• Set increment for arrow keys – It is now possible to set the increment for moving Objects with the arrow keys in the Preferences. [PPDPDF-1551]
• Import Spot Color libraries – ASE files can now be imported and used as color libraries in the PDF Editor. [PPDPDF-823]
• Assign ICC profiles to Vectors or Text – ICC profiles can be assigned to or removed from Vector and Text Objects. [PPDPDF-1489]
• Downsample Image Resolution – The function for changing the Image Resolution has been implemented. [PPDPDF-645]
• Editing Metadata – The dialog Document Info has been expanded to include the option of editing Metadata. [PPDPDF-1454]
• Lock Open Files – Automatic locking when opening PDF files has been disabled by default in this version. If you still prefer this behavior, you can enable the option «Lock Open Files (Restart required)» in the Preferences. [PPDPDF-1505]  

The following improvements have been implemented to simplify operation:

• Local saving of files from a Workflow System – The behavior when saving files locally has been improved. Locally saved files are no longer automatically checked into the Workflow. [PPDPDF-1511]
• Restructuring of Actions in the tab »Edit« – The revised structure in the tab Edit provides users with a clearer list for quick access to Actions. [PPDPDF-1540]
• Convert Text to Outline – The function »Convert Text to Outline« now converts Text into individual glyphs that can be moved or edited separately. [PPDPDF-1429]
• Standardization of the »...« menu – The »...« menu has been standardized across the entire application, and the point size has been increased. [PPDPDF-1535]

• Page Size in the tab »Lists > Pages« – The TrimBox is now always displayed. If no TrimBox is defined, the MediaBox is used as a fallback. [PPDPDF-1499]
• Formatting in the tab »Workflow« – The display of information in the tab Workflow has been revised. Descriptions of Print Items are now centered vertically. [PPDPDF-1497]
• Display thin lines more clearly– The display of very thin lines (threshold value: > 0,3 pt) has been revised. These are now automatically detected and displayed more prominently on the screen if the corresponding option is selected in the PDF Editor Preferences. [PPDPDF-1009]

The following Bugs have been fixed in the PDF Editor with this Release:

• Delayed loading of the Image List – Preview Images in the Image List were loaded late or not at all. This behavior has been improved. [PPDPDF-1400]
• Incorrect loading of Preview Images – Preview Images were loaded from the wrong document. This error no longer occurs; Preview Images are now loaded from the selected document. [PPDPDF-1400]
• Exiting the application on macOS – Exiting the application on macOS could cause a crash under certain circumstances. Such crashes no longer occur. [PPDPDF-1399]
• Opening multichannel TIFF files – TIFF files now open reliably with EGCs. [PPDPDF-1525]
• Application icon macOS compliant – The application icon is now displayed in the standard macOS size. [PPDPDF-1513]
• Move Text with the Shift key – When moving Text with the Shift key, Text Objects were distorted or positioned incorrectly. This behavior has been fixed. [PPDPDF-1488]
• Incorrect coordinates when adding Dielines – Dielines may have been placed at incorrect coordinates. This error no longer occurs. [PPDPDF-1520]
• Change object order – In complex PDF files, Objects could not be moved correctly to the foreground or background. This behavior has been fixed. [PPDPDF-1504]
• Open PDF with multiple pages – When opening Multipage PDF files, the pagination was sometimes not displayed. This bug has been fixed. [PPDPDF-1502]
• Display Transparency Grid – The transparency grid could not be activated. This error has been fixed. [PPDPDF-1501]
• Using Output Intent for Display – Until this version, PDF files with embedded Output Intent could not be processed. This behavior has been fixed in version 1.12 of the PDF Editor. For the application, it is recommended to use Color Profiles from the directories /Library/ColorSync/Profiles und /Users/{USER}/Library/ColorSync/Profiles/. [PPDPDF-1314]

Below you will find a detailed description of all changes in the categories New Features and Improvements.

Starting with version 1.12, the PDF Editor has a new feature for visually comparing changes to the saved version or to another document.

By default, the comparison is made with the currently saved version, allowing you to visually check any changes you have made to the PDF file. However, using the selection menu of the option Compare with [11] (Figure 2), you can also select a different, user-defined document for comparison, provided that it is already open in the PDF Editor.

The documents are aligned precisely with each other and superimposed for comparison based on defined page margins – by default, the TrimBox. A transparent visualization mode ensures that the reference document remains visible while differences are highlighted in color. This display is based on a digital Overprint comparison, enhanced with selective transparency for better traceability.

In the area Sensitivity [10] (Figure 2) the user can choose between three levels High, Medium, or Low to adjust the Sensitivity of the difference analysis to specific requirements.

To perform the PDF comparison, proceed as follows:

1. Navigate to the tab View [2] and select the tab Visualize [3].
2. By selecting the entry Combined View [4], all areas that require checking are highlighted in color. In our example, the pink highlighting indicates that both Texts would change color in the printout or even disappear.
3. In the selection menu of the Highlight Area [1], select the option Compare [5] [9].

Figure 1: The view in the tab View > Visualize

4. After activating the Comparison Mode, make some Fixups for selected Objects. To edit the file, you need to switch to other tabs of the PDF Editor to make the desired changes. In our example, the following changes should be made:
   • the large Text [6], which is Overprinting, should be set to Knockout.
   • the sun [8], which is an Image in RGB Color Space, should be converted to CMYK.
   • the color areas [7] in the wave should be slightly changed.
5. When you return to the tab Visualize [3] (Figure 1) after editing the Objects, the changed areas are highlighted in color. Light yellow areas differ only slightly, dark yellow areas differ more significantly, and red areas differ extremely.
6. If you cannot see much, select High from the dropdown-menu Sensitivity [10]. This allows you to immediately see which areas differ significantly from the original version.

Figure 2: The view in the tab View > Visualize after editing a PDF file

This New Feature provides a precise and configurable PDF comparison function, ideally suited for use in prepress, layout control, or quality assurance.

In version 1.12 of PDF Editor, the existing function Crop Images to Visible Content has been extended with the option Crop Image to Page Box. Image content outside the selected Page Box – e.g. the TrimBox – is removed in addition to the cropping path of the Image, so that only the Image area relevant for printing remains.

The function Crop Image to Visible Content, combined with the additional function Crop Image to Page Box, is used to reduce superfluous Image data in print PDFs and supports structured, production-oriented data preparation. It minimizes potential sources of error, improves data consistency, and optimizes further processing, for example during print sheet assembly or in prepress Workflows.

Starting with this version, the PDF Editor offers three alternative ways to access the function Crop Images to Visible Content:

• Via the menu Edit > Optimize Document > Crop Images to Visible Content (Figure 3).
• Via the tab Lists > Images > Crop Images to Visible Content (Figure 4).
• Via the icon »Crop Images to Visible Content« in the footer of the tab Lists (Figure 4).

The following sections describe in detail the two options for the function Crop Images to Page Box via the menu Edit > Optimize Document and via the tab Lists > Images.

In version 1.12, the functionality in the tab View > Analyze [17] has been expanded to further refine the visual and content-related checking of PDF files.. A new filter option is now available in the settings areas Color Spaces and Page Objects to identify and evaluate complex Color Objects:

• DeviceN Colors [18] [19] – Objects based on the DeviceN Color Model can now be filtered and analyzed. Two DeviceN entries can be found in the list of Color Spaces:
  • DeviceN (CMYK only) – Specifies Objects that are composed of the colors DeviceN Cyan, DeviceN Magenta, DeviceN Yellow, or DeviceN Black.
  • DeviceN – Specifies Objects that are composed of at least one or more Spot Colors.
• Smooth Shades [20] – Objects with Smooth Color Gradients (without visible banding) can now be displayed and analyzed separately. This enables early identification of potential issues in gradient output, such as banding in Screening or Digital Printing.

These two new filters enhance transparency and control when working with complex layouts and advanced color spaces – especially in professional printing environments and prepress Workflows.

Figure 5: The tab View > Analyze with the filter options Smooth Shades and DeviceN Colors enabled

Starting with version 1.12, the PDF Editor offers the ability to select a Simulation Profile – ICC-Profile – for Color Preview. This allows for a realistic on-screen simulation of how colors will appear under defined printing conditions (e.g. ISO Coated v2 (ECI), PSO Coated NPscreen ISO12647 (ECI)) during the editing process.

The Simulation Profile [21] can be selected directly by the user in the footer of the PDF Editors application frame.

Figure 6: The PDF Editor with a selected Simulation Profile

To the question of which simulation profile is displayed by default for a document, the following answers apply:

• PDF/X files – When opening a PDF/X file, the profile defined in the embedded output intent is used as the Simulation Profile.
• Non-PDF/X files – The ICC Profile set in the Preferences of the PDF Editor as the CMYK Working Color Space is used as the Simulation Profile. You can change the Simulation Profile at any time – however, please note that a Custom Simulation Profile is not saved with the PDF file when exporting for print.

This function provides a color-accurate on-screen Preview based on professional print conditions – a key advantage for quality control in prepress Workflows.

With version 1.12, the PDF/X export functionality in the PDF Editor has been extended with the essential option to select an Output Intent. In the dialog Save As, the Output Intent [22] can be selected if a PDF/X entry is selected in the PDF version. This allows you to control specifically for which print condition the saved PDF/X file was prepared by the data creator, ensuring consistency in the processing of the PDF file across all production stages – from prepress to the printing press.

Figure 7: The dialog Save As in the menu File with extended PDF/X export function and selected Output Intent

As of version 1.12, the embedded ICC Profile [24] of each Image is displayed in the tab Lists > Images [23]. This provides users with important information about the color characteristics of embedded Images at a glance, which is a decisive advantage in color-critical Workflows.

If no ICC profile has been assigned to an Image, the clear label Not embedded [25] appears. This enhancement facilitates the checking and assessment of color consistency in PDF files and supports secure and standard-compliant further processing in prepress.

Figure 8: The tab Lists > Images showing the embedded ICC Profiles

With version 1.12, the usability of the PDF Editor was further improved. Selected Objects can now be rotated freely using drag points at the corners [26] – without any numerical input. Objects can be rotated flexibly and positioned precisely by simply dragging the corner points. The rotation angle [27] is displayed during rotation. An exact angle can be entered in the tab Edit > Edit Object.

This enhancement greatly simplifies the design of complex layouts and the post-processing of print data that requires individual object adjustment.

Figure 9: A selected object is rotated

With version 1.12, the Transparency reduction function in the PDF Editor has been enhanced with a very important practical feature: the ability to exclude Spot Colors from Transparency reduction. This feature is particularly important for technical Spot Colors such as «Die Cut» or «Crease», but also for Spot Color Channels such as «White», «Primer», or «Varnish», as these Spot Colors must not be rasterized or modified because they are essential for further processing in the printing process.

By specifically excluding these Spot Colors, you can ensure that they are not offset against background Objects or converted into Pixel Images. Instead, they remain unchanged as Vector Objects even after Transparency reduction. This increases production reliability and ensures correct technical implementation in further processing.

To exclude Spot Colors from Transparency flattening, proceed as follows:

1. Open the dialog Optimize Document via the menu Edit > Optimize Document....
2. In the dialog that opens, enable the option Flatten Vector Transparencies [28] and select the desired reduction setting [32] for transparency reduction.
3. Optionally, you can also activate the option Remove Objects on Invisible Layers [29].
4. In the settings area Do not include, you must activate the Spot Colors that are to be excluded from the Transparency reduction, e.g., Die Cut [31] or Crease [30].
5. Confirm your settings with OK.

The selected Spot Colors are excluded from the Transparency reduction, which means that their Spot Color definitions are retained independently of the rest of the Transparency structure. This extension contributes significantly to quality assurance and ensures the technical correctness of the Print Data in further processing.

Figure 10: The dialog Optimize Document with selected Spot Colors that are to be excluded from Transparency flattening

As of version 1.12, the PDF Editor offers the ability to convert Images to a different color space – either RGB, CMYK, or Grayscale.

This feature allows you to precisely convert the color values of embedded Images to the desired output color space by selecting the Target Profile. The conversion can be applied to individual Images as well as to multiple Image Objects in the document.

To convert an Image to a different Color Space, proceed as follows:

1. In the PDF Editor, navigate to the tab Lists > Images.
2. Select the desired Image(s) with a mouse click.
3. Right-click to open the conText menu and select the menu entry Convert to ICC Profile... [33].
4. In the dialog that opens, configure the following settings in the Target section:
   • the desired Target Color Space [34] – RGB, CMYK or Grayscale –,
   • the Target Profile [35] for the intended Color Space,
   • the Rendering Intent [36] for the conversion as well as
   • the Use Black Point Compensation [37] should be applied or not.
5. Confirm your selection by clicking OK.

This feature provides advanced control over Color Processing and supports Data Preparation for different Printing conditions or adaptation to different Output Channels.

With Version 1.12, the Increment for Cursor Keys [38] can be defined in the Preferences of the PDF Editor. This determines the Offset by which a selected object is moved to the left or right and up or down when you press the left or right Cursor Key or the up or down Cursor Key.

This customization enhances flexibility and precision during manual object alignment, offering significant advantages, especially when working on fine details.

Figure 12: The dialog Preferences with the option Increment for Cursor Keys selected

With version 1.12, the PDF Editor has been enhanced to allow importing and managing Custom Color Libraries in ASE format (Adobe Swatch Exchange) within the Preferences of the PDF Editor. After import, this special Color Library is available System-wide within the PDF Editor, allowing brand-specific Color Palettes to be applied consistently throughout the document.

To import a user-defined ASE color library into the PDF Editor, proceed as follows:

1. Open the menu Preferences in the PDF Editor.
2. In the dialog Preferences that opens, navigate to the section Color Management.
3. Click on the button Define Spot Color Library...[39].
4. The dialog Edit imported Spot Colors opens.
5. Click on Import ASE Color Spot Library...[42].
6. Select the desired ASE file from your File System and confirm with Open.
7. After successfully importing the Color Library, confirm the operation with OK to apply the Color Library.
8. You will automatically return to the dialog Preferences. Confirm your entry with OK to permanently save the imported Spot Colors.
9. The imported Color Library is now available throughout the PDF Editor and can be used when assigning Spot Colors to Objects, Texts, or Areas.

Figure 13: Left: The dialog Preferences with the button Define Spot Color Library...; Right: The dialog Edit imported Spot Colors and the dialog Edit Spot Color

In the dialog Edit imported Spot Colors, you can perform the following actions:

• Edit [40] – The selected Spot Color can be edited to change the alternative Color Space [44] and the alternative Color Values [45].
• Delete [41] – One or more Spot Colors can be deleted permanently.
• Search [43] – By entering a search criterion, you can quickly filter an extensive list of Spot Colors.

Whereas users were previously only able to assign ICC Profiles to Images and remove embedded ICC Profiles from Images, version 1.12 now makes this possible for Vector and Text Objects as well. This enhanced feature allows Objects to be marked with the desired Color Profile for consistent Color Conversion.

In the PDF Editor, you can assign or remove ICC Profiles in three different ways:

1. In the settings area Color of the tab Edit > Edit Object.
2. Using the command Assign ICC Profile... in the tab Lists > Images.
3. By calling the command Assign ICC Profile from the conText menu for the currently selected Image Object.

Version 1.12 introduces a new feature for reducing Image Resolution. This deliberately reduces the amount of data in an Image by reducing the number of Image Pixels (Data Points).

This feature allows oversized or high-Resolution Image Data to be adjusted in a controlled manner to meet specific production requirements, such as reducing file size or improving performance in the RIP process.

There are two options available for reducing the Resolution of an Image, which are described in detail below:

• Reduce Image Resolution for selected Images – via the tab Lists > Images
• Reduce Image Resolution of all Images on the current page – via the tab Edit > Actions > Optimize

Version 1.12 introduces the option to edit PDF Metadata – Title, Author, Description, Keywords, and more – in the tab General of the dialog Document Properties. This information is crucial for structured file management, archiving, and the creation of standard-compliant PDF documents (e.g., according to PDF/X or PDF/A).

For a better overview, the editable fields are highlighted with a white background. Double-clicking on these fields allows you to enter Text directly. This new feature makes it easier to quickly adjust Metadata, improves the search of files, and ensures legally compliant documentation when sharing or publishing PDF files.

With version 1.12, the following PDF Metadata can be edited directly in the PDF Editor:

• Title – Internal name of the PDF file. Ideally, this corresponds to the file name to ensure unique assignment.
• Author – Name of the author – used to improve identification and search of the file on the Internet.
• Description – Additional information – Free Text field for a description of the content – used to make the PDF file easier to find on the Internet.
• General – Free field for additional descriptive information used to improve the categorization and search of the PDF file on the Internet.
• Keywords – Relevant keywords for categorizing the content and improving the search of the PDF file on the Internet.
• Author of the description – Name of the author of the Metadata Description.
• Copyright information – Additional information that may contain references to protected content within the file.
• Copyright protected – Additional information indicating whether the file is protected by copyright.
• URL for copyright information – Additional information – Web address with further information on the legal protection or terms of use of the file.

Figure 18: The tab General of the dialog Document Properties

Automatic locking when opening PDF files has been disabled by default in this version. If you still prefer this behavior, you can re-enable the option Lock Open Files (Restart required)  in the Preferences.

This feature allows you to automatically lock all PDF files opened in the PDF Editor. The purpose of this feature is to ensure the integrity and security of important documents by preventing accidental changes or parallel access. It can be activated in the Preferences of the PDF Editor and provides an additional layer of protection for recurring work processes with defined documents.

To reactivate this feature, proceed as follows:

1. Open the PDF Editor and load the desired PDF document.
2. The quickest way to open the Preferences is to press the keyboard shortcut Ctrl + , (Windows) or cmd + , (macOS).
3. In the section General, activate the option Lock Open Files (Restart required) [61] by clicking the checkbox.
4. Confirm your entry by clicking OK.

From now on, all files opened when the PDF Editor is started will be automatically protected against unintentional changes.

Figure 19: The dialog Preferences with the new option Lock Open Files (Restart required)

In version 1.12, the behavior when saving PDF files from connected Workflow Systems locally has been improved. Locally saved files are no longer automatically re-uploaded to the Workflow when saved locally. This change allows users to process or archive PDF files locally, independently of the connected Workflow, without overwriting the original document in the Workflow. This increases control over the document flow and prevents accidental changes in the Workflow.

To save a file locally, proceed as follows:

1. Open the tab Workflow [62] and connect to the desired Workflow.
2. Select the document [63] that you want to check out from the Workflow. The selected document is highlighted in blue.
3. Open the file in the list of Print Items by double-clicking it, or click Check out [64] to release the document for editing in the PDF Editor.
4. To save the PDF file locally, select File > Save As....
5. In the dialog box that appears, select a local storage location, e.g., your Workstation [65] or a Network Drive [66].
6. If necessary, assign a new file name [67] and save the PDF file by clicking Save [68].
7. The file is saved locally without being automatically uploaded back to the Workflow.
8. Any further editing of the document will then be saved locally only.

Figure 20: Left: The tab Workflow with a selected document; Right: The dialog Save As on macOS

In version 1.12, the tab Edit > Actions [69] has been restructured. The available Actions are now grouped systematically according to their focus, giving the user interface a much clearer and more efficient structure.

The revised structure improves navigation-based operation during object editing and allows faster access to frequently used tools. The functions are now divided into five groups:

• Arrange [70] – These functions allow you to precisely position selected Objects relative to each other or to the page, e.g. by centering and spacing them evenly.
• Separations and Objects [71] – This group includes the following actions:
  • Add Dieline... – Adds a Dieline to the selected origin and the defined offset of the print file.
  • Create Spot Color Separation... – Creates a new separation channel for the selected origin and the defined offset.
  • Offset Path... – Moves selected path Objects inward or outward by the specified offset.
• Fonts and Text [72] – This group includes the following actions:
  • Embed all system-available fonts – Embeds missing fonts in the PDF document if they are available on your local system.
  • Convert Text to Outline... – Converts all Text in a document – applies to all pages – to Vector Paths.
  • Convert selected Text to Outline... – Converts the selected Text Objects to Vector Paths.
• Pages [73] – This group includes the following actions:
  • Add Bleed… – Creates a bleed at the specified spacing by mirroring the Objects.
  • Scale Current Page… – Changes the page size for the current page by scaling the content by a percentage or absolute value.
  • Delete Objects Outside Page Box... – Removes all Objects that are completely outside the selected page box.
  • Set MediaBox to Origin... – Resets the MediaBox to the origin 0/0 of the coordinate system.
• Optimize [74] – This group includes the following actions:
  • Optimize Document... – Reduces the file size by cleaning up redundant data, flattening the contents, and removing unnecessary Objects – without visual impairment.
  • Downsample Image Resolution to... – Reduces the Resolution of all Images on the current page.

Figure 21: The tab Edit with the newly structured Actions

In version 1.12, the function Convert Text to Outline has been revised. The individual letters of Text Objects are now converted into individual glyphs, so that each character is available as a separate Vector object. This allows individual letters to be edited, positioned, and transformed separately.

The conversion is lossless and preserves the exact shape of the characters as pure Outline Objects – regardless of embedded font, font style or font size. Texts with non-embedded fonts cannot be converted to Outlines, as there is no description of the curves for the letters.

If you want to Convert Text to Outlines, the PDF Editor offers two options:

1. Via the menu Edit, which contains the following commands:
   • Convert Text to Outline... [76] – Converts all Text in the document to Outlines. Alternatively, you can also access this function using the keyboard shortcut cmd + Shift + O (macOS) or Ctrl + Shift + O (Windows).
   • Convert selected Text to Outline... [75] – Converts only the selected Text to Outlines.

Figure 22: Menu Edit with the two menu commands

1. Use the option Convert Text to Outline... [77] in the tab Edit > Actions > Fonts and Text.

Figure 23: The tab Edit > Actions with the option Convert Text to Outline...

In version 1.12, the  «...» menu [77] [78] (three-dot menu) has been visually standardized throughout the PDF Editor and optimized in terms of display size to ensure better usability on high-resolution displays (e.g., 4K monitors). The adjusted display makes the menu easier to use with touchscreens or digital pens – ideal for tablets or hybrid devices.

Figure 24: The tab View > Analyze and the tab Edit > Edit Object with the standardized «...» menu

In version 1.12, the display of color values in the tab View > Analyze has been revised. From now on, the Color Values of Hidden Separations [79] are no longer displayed in the Process Colors and Spot Colors panels. Only the color components of the Separations that are actively displayed are evaluated and shown.

Figure 25: The tab View > Analyze with hidden Process Colors (Magenta, Yellow) and Spot Colors (PANTONE 2726 C)

Starting with version 1.12, the Page Size [81] is displayed by default in the tab Lists > Pages [80] based on the TrimBox. If no TrimBox is defined in the PDF document, the PDF Editor automatically uses the MediaBox as a reference for displaying the Page Dimensions.

This adjustment ensures reliable and consistent display of the relevant Page Sizes – regardless of the technical definition of the PDF document – and thus supports precise evaluation of print-relevant formats.

Figure 26: The tab Lists > Pages with the Page Size display

In version 1.12, the formatting of the list view in the tab Workflow [82] has been revised. The information contained is now centered vertically in relation to the Preview Image [83], and Print Items that are currently open in the PDF Editor are marked with the note Checked out [84].

Figure 27: The tab Workflow in the new Layout

The version 1.12 introduces the new option Display thin lines more clearly [85] in the Preferences of the PDF Editor. This option makes very thin lines with a stroke width of less than 0.3 pt appear more clearly.

This new option improves the display of Technical Drawings, Plans, and vector-based content without changing the actual line thickness in the PDF document or when printing. This ensures that fine details remain clearly visible even on high-resolution displays and when zoomed in.

To access this feature, proceed as follows:

1. Start the PDF Editor and open the desired PDF document.
2. Open the Preferences of the PDF Editor – the easiest way is to press cmd + , (macOS) or Ctrl + , (Windows).
3. In the section General, activate the option Display thin lines more clearly [85] by clicking the corresponding checkbox.
4. Confirm your entry by clicking OK.
5. The screen display is adjusted immediately: Very fine lines appear slightly enhanced and are more visible – without any changes to the original document.
