3.2. Before/After
To experiment with this function, refer to the sample file "Sample_Convert Black Text to Rich Black.pdf". The file contains black text with the CMYK color values 0/0/0/100. This text should be converted to Rich Black with the CMYK values 50/50/0/100.
After applying the Fixup, the file "Sample_Convert Black Text to Rich Black_End.pdf" is created. The black text elements were converted to Rich Black. The values from Figure 1 were used for this.
