Hi to all. I want to export a document that has several curves that the blend mode is set to color dodge with no transparency, but as soon as i publish to pdf or tiff or jpg, the exported file doesn't keep the blend for the curves. Any suggestions about it?
Without seeing an example I cannot suggest a path to proper output, however importing Illustrator files with layers, blends, gradients and transparency is like shooting yourself, not recommended.
First AI CC2015 files are regularly failing in our 3 RIPs, secondly AI EPS and PDF files are in many cases not true EPS and PDF files, they're Illustrator specific EPS and PDF files so exporting or importing them to anything but Illustrator is a non starter.
With that said if you can get the right transition and if the RGB is not out of gamut you should be able to get I to CMYK and to output.
