4/c tiff

[older]

We have a 5 pms color bc that has a 4/c background tiff that is suposed to be screened reflex blue. How do we tell what percent screen it should be?
Graphics says they can change it when they know the screen. The file says 15% but they don't trust it. It's a shame that this card is our own and has been printed before, but the files were deleted from prepress archives by mistake. Sure hope someone can help. ops:

Just find the darkest portion of the image, and read what the Cyan channel is. Since there is 100% cyan in the process recipe for reflex, this should get you there.

Actually, you could just go to your cyan channel and convert it to grayscale (other channels will be discarded), save as TIFF and place in your layout at 100% PMS - the screening is already taken care of.
