I have an .ai document, this is my working document. ! want to export it to PDF (to be portable but still vector), the problem is the color are all messed up and seem washed out (in spite the fact I included the color profile):
If I export it as PNG the colors are correct:
How can I do to have a PDF with the colors I want?
I would guess that your PDF is a CMYK file rather than RGB. If you're then viewing the PDF with something other than Acrobat or Adobe Reader, the colors in the file may be being interpreted incorrectly when rendered for your screen.
Try the PDF save using the "High-quality Print" setting, which is an RGB mode for desktop printers, and see if that makes a difference.
