Overprinting/trapping issues...

[Silence04]

so i've come to this cross in the road once again....

I've got a 2 color job that is using 4545U and 7498U, printing on a white material. (4545U is for the text, 7498U is for the background... with total coverage, no white material will be showing through)

The problem, is of course, the trapping that will be required... when both of those inks get on top one another it will create a dark green outline around all the text; which will hinder the design because it's being printed at a small size (about business card size).

So I'm thinking the fix would be to flood the material with 4545U, then overprint a lighter green pms on top to net out a green that looks like 7498U.
but how am i suppose to know what lighter green pms to choose?

Am i over complicating this, should i just live with the trapping?
Are overprints always a shot in the dark when you can't be at the printshop for a presscheck?

any advice?

Have you discussed this with your printer yet? They usually offer great advice when it comes to trapping and text. That can be a tough one sometimes. But most vendors should be able to give you the proper advice. I personally wouldn't even know how to do trapping on my own. I think more designers than not, leave that up to the printer, and take their advice as necessary to get the best output. I just know that small type and certain color situations to ask my printer about it. :) They know more than I do in that area!

it's 100% opaque (or foil), because the text will vanish on the dark background.
You'd have to knock out and trap if this is the case.

Are overprints always a shot in the dark when you can't be at the printshop for a presscheck? To some degree yes. 7498U is dark enough that if you flooded the background
with the 4545U overprinting probably wouldn't make the 7498U too much
darker, though it will a little. 371U might build to about 7498U when
overprinting 4545U. I'd check with the printer though.
