Displaying overprinting opaque inks in Illustrator / PDF

[Stephen Marsh]

why can you do this to the Blue ?.......but you can not do this to the gold ?
what's the reason you knock out the blue from the brown

Spider, it is my guess that the person soft-proofing these files is savvy enough to know that the gold should not knock out the underlying inks and that it is opaque and probably printing last in the ink sequence - while the blue is printing earlier and the ink is transparent and thus requires a knock-out and trapping.

Hi All,

Thanks all for the relpies, sorry for not replying sooner I thought I received email notification for replies but obviously not!

Yes the client is soft proofing these and we have a 'single pdf' workflow, therefore the same PDF get approved that is the print tool. Therefore I can't have two pdfs one thats correct for colour and the other thats correct for separation. The gold is not gripped/trapped and just overprints (like a foil gold) where the other colours trap. Esko lets you define ink separations that are opaque and provides a pdf that looks correct and prints correct, I am looking for an alternative. I hope I'm making sense ?

Why do you need color under the gold? If trapped correctly you wouldn't need color under the gold.

simply because the mis-registration error is higher with metalic foil blocking station than a normal colour, so the trap/grip would have to be larger plus the foil is opaque to cover the inks without any show-thru.

See attached pic of Esko's ink manager window. This lets you define ink properties /print sequence. Unfortunately I only have a demo version !
