Q:
Is there any issue with printing 400% black? There is a children’s book we’re doing that may need to be adjusted if this is an issue. I know some printers need black to be below 300%.
A:
We normally ask that the maximum ink density is 300% for each ink (CMY & K), but for coated GLOSSY sheets that density can increase to 350%. For uncoated or coated MATT sheets, we suggest sticking to 300% or lower. One thing to think about with high ink density is offsetting: if you want to have a super saturated sheet, a varnish should really be applied to prevent offset.
Hope this helps!
