In this article, you will learn
- which prerequisites must be met for this Fixup,
- how to apply this Fixup.
1. Introduction
In the $PRODUCT_NAME_WORKFLOW application, the Reinforce White Objects Fixup is available. The purpose of this Fixup is to enlarge white objects such as lines, vectors, or text by the specified value.
2. General
The Reinforce White Objects Fixup can be used to increase the line width of lines (strokes), vectors, or text. This Fixup can be used, for example, to slightly reinforce negative text in digital printing. This can improve the readability of small text while preserving the text itself.
You can find this Fixup in the Data Preparation tab of an Article, Order or Production Job by:
- entering the name of the Fixup in the Filter area,
- activating the option Color in the Category area,
- activating the option Add in the Action area,
- activating the option White or Stroke in the Property area.
3. Description
With this Fixup white lines, vectors, or text can be enlarged or reinforced by the specified value. This can improve the readability of negative text.
3.1. Prerequisites and Functionality
To ensure that the Fixup can be applied as intended, the following requirements must be met:
- The file contains white objects.
- The white objects are defined as CMYK (0/0/0/0) or grayscale (0%). RGB or Lab white is not recognized.
The Reinforce White Objects Fixup consists of three individual Fixups that are combined in a single dialog.

The individual Fixups are described in detail below:
3.1.1. Reinforce White Lines
By default, this Fixup is enabled, as indicated by the activated checkbox [1]. When this Fixup is enabled, white lines (strokes) are reinforced by the specified value.
The following options are available for reinforcing white lines:
- For Line Width less than [4] – enter the line width of the lines to be reinforced. For Variable Content [6], select the desired placeholder – database field or user-defined field – from which the line width should be retrieved.
- Set Line Width to [5] – enter the new line width for the lines identified previously. For Variable Content [7], select the desired placeholder – database field or user-defined field – from which the line width should be retrieved.

3.2. Before/After
To experiment with this function, you can use the sample file "Sample_Reinforce White Objects.pdf". The file contains white lines and white text as well as white vector objects. The moon in the background was created as a vector object. A white line is incorporated into the yellow road line running through the center. A line of white text can be found above the car. All objects were created using CMYK white.
After applying the Fixup, the file "Sample_Reinforce White Objects_End.pdf" is created. In this file, all white objects have been reinforced. All three Fixups were enabled and the values shown in Figure 1, Figure 2, Figure 3 and Figure 4 were used.
