Why did the dull varnish not show as dull?

Answered by Suzanne Morgan

I recently had my printer print a two-pocket 9 x 12 folder using 10 pt. Kromekote C1S. I specified dull in-line varnish to dull down the heavy ink coverage areas on the front cover, in order to "pop" the unvarnished predominantly white areas. End result? There was no distinguishable difference between varnished and unvarnished areas on this paper. I know dull aqueous or dull UV would have been more obvious, or even dry-trap dull varnish, but the cost would have been significantly greater. However, no difference whatsoever? What went wrong?

There may be several reasons why the dull in-line varnish didn't appear dull enough -- if at all.

So, in addition to the above, here are a few things that you could do to avoid that problem in the future.
