In this article, you will learn
- which prerequisites are required for this Fixup, and
- how to apply this Fixup.
1. Introduction
The Fixup Redye CMYK Objects is available in the Workflow. The purpose of this Fixup is to redye detected CMYK objects and change the appearance of the Print Item.
2. General
The Fixup Redye CMYK Objects can be used to redye CMYK objects. For example, a classic black can be converted to Rich Black, resulting in the objects being printed in a "darker" black.
You can find this Fixup on the tab Data Preparation of an Article, Order or Production Job by:
- entering the name of the Fixup in the area Filter,
- activating the option Color in the area Category,
- activating the option Change in the area Action,
- activating the option CMYK, Spot Color or Vectors in the area Property.
3. Description
This Fixup can be used to redye the desired CMYK values. If the redye should be restricted to certain object types, this can be done by selecting the appropriate object type.
3.1. Prerequisites and Functionality
For the Fixup to perform as intended, the following requirement must be met:
- The file contains vectors or texts that are colored with CMYK.
Figure 1: The dialog of the Fixup Redye CMYK Objects
To redye fills, strokes, or text , the following options can be selected:
- Templates [1] – settings selected in the dialog can be saved as a template and applied to other Articles/Print Items, as well as used within Fixup Chains and in the Operations Apply Fixups and Check Print Item and Apply Fixups.
- Apply to [2] – select in the selection menu which object types should be affected. The following options are available:
- Text – all texts of the original color are redyed.
- Vector – all vectors of the source color are redyed.
- Text and Vectors – all texts and vectors of the original color are redyed.
- Variable Content [6] – for Variable Content [6], select the desired placeholder – Database Field or User-defined Field – from which the value for the selection of object types should be retrieved. The following values must be present in the selected field for the selection to be created:

- Source Color [3] – enter the CMYK color value of the texts, vectors or both texts and vectors that should be redyed.
- Tolerance [4] – enter the desired tolerance for each color value. By entering a tolerance, not only is the exact color value determined, but the entered tolerance is also taken into account.
For example: If the color value 10/20/40/0 is searched for and a tolerance of 1% is entered, the color values 9/19/39/0 and 11/21/41/1 will also be included. Since inaccuracies in color conversion can always occur, a small tolerance is useful. For Variable Content [8], select the desired placeholder – Database Field or User-defined Field – from which the value for the respective tolerance should be retrieved. - Target Color [5] – enter the CMYK color value that the selected objects should subsequently have.
- Include intermediate color values [6] – when this option is selected, all tonal values of the searched CMYK value are included.
3.2. Before/After
To experiment with this function, refer to the sample file "Sample_CMYK_Redye.pdf". The sample file has a size of 300 x 300 mm. The design consists of vector objects and a text line that have been created in different CMYK colors.
After applying the Fixup, the file "Sample_CMYK_Redye_End.pdf" is created. All objects that were previously colored in Magenta (0/100/0/0) were redyed to Cyan (100/0/0/0).
