I’ve been using Planetpress for a particular project which colors are extremely important (part of our customer branding). Somehow I specify in PP Design those colors in CMYK, everything is fine until I generate a PDF (Windows Printer) (Acrobat Pro) . All the colors changes for other values than the one enterred.
The only way to get the proper colors so far : Print, still Acrobat Pro, but print as a file.
After I have to distill the EPS/PS file, remove the WaterMarks (of a paid software…) and it’s the only way to get the colors I defined in my project.
