Nexus PDF workflow with preps 5.3

[lildfly]

ive recently gone to pdf workflow using nexus 9.5 and preps 5.3. everything is working seamlessly except my In-RIP Color ID marks, preps is giving me an error that it cannot find the file? these files work great in ps workflow but aren't working in the pdf workflow. does anyone know fix? is there another way i can create custom mark in preps that will give me color separation info for each color on my final output? thanks

Did you convert your marks to PDF? You will need to do that for them to work in Preps.
