Before checking and changing screens on a PDF page, you must refine, color-match, and (optionally) trap the PDF file in Prinergy.
- Use a composite Adobe PostScript or PDF file for the input file, since color-matching makes changes that can only be done to a composite file.
- Embed any fonts that are used in the input file, either while creating the PostScript output file in the source software, or in Prinergy during the refine process.
- Select CEPS Conversion in the refine process template. This allows the components of CT/LW files to be converted into a format that DotShop screening can be applied to.
- Set up the Color Matcher JTP in the refine process template to convert RGB colors to CMYK colors. Depending on your input file or design requirements, you may select:
- Map All Spot Colors to Process (in the Spot Color Handling section)
- Set Colors to Knockout (in the ColorConvert section)
Note: Do not set colors to knockout when you will need double hits of spot colors. - Set Black to Overprint (in the ColorConvert section)
Once the PDF file is successfully set up and refined, you can check, change, and/or add screens in the refined PDF pages using DotShop.
