Following Conversion from RGB to CMYK loses mesh gradient transparency , I replaced the mesh gradients with simple transparency gradients in Illustrator CS5.1. Note that the blue and red emojis have white spots on the eyes and a gradient in the face color:
When I save as a PDF with Uncoated FOGRA 29 color profile, those two emojis lose the white spots and the gradient in the face color. Here is the result in PDF, which is also missing those nuances after I upload to the manufacturer's website:
I used an ellipse and then the gradient tool with white color on the stop points and different opacity values:
When I change the stop colors to solid colors, then the gradient renders similarly in Illustrator and in the PDF. I would rather avoid changing all my gradients to these colors.
Is it possible to make the opacity gradients work in CMYK with FOGRA 29?
