Today was without a doubt the worst day of printing I've ever had.
I'm trying to print some fine dots over a layer of silver ink, which is quite rough and textured. Everytime I do a perfect print on newsprint, the black ink just doesn't take to the silver. I feel like I've tried everything, but also feel a little burnt out with this and other things. Wish I just used grey instead.
Anyone got any tips on printing 60 dot frequency halftones over rough silver ink? Thanks guys.
Metallic inks trap poorly, to keep them from scuffing they have a surface finisher that raises to the top as they dry. Trap is one of those multi-use terms that can mean a slight over print to aid register OR the ability of one ink to stick (trap) to another. Metallic inks need to be overprinted ASAP before the scuff barrier sets.
