Exporting to pdf with CMYK transparency
I have a shape with a CMYK fill color and a transparent image. When I export it to PDF the colors get distorted. In the export the color setting is in CMYK.
What I noticed is when I change
Transparency blend space > Document CMYK to
RGB I get the colors as they are in the PDF.
What can I do to export with the intended colors?
Eventually I realized I had several issues:
- I used CMYK dark gray: (c0,m0,y0,k95) which was converted on export to light gray (Although in InDesign output settings it was set to
Display all blacks as rich black). I solved it by adding color to the gray (c60,m50,y50,k80)
- The images were in RGB, so the color changed a little on export. Converted all to CMYK with photoshop, so no surprises there.
export settings > outputI had to use color conversion > convert to CMYK
And got all the colors right in the PDF
