Method for Eliminating Fill Areas Lower than 100% Photoshop
« on: December 09, 2016, 01:48:03 PM »
This is likely a "dumb" question.  We had a spot color file in PS that totally effed us, all channels where thresholded but it left certain areas at 99% K.  Couldn't see it on monitor in PS, couldn't catch it in pre-flight where we use a a temperature map to catch this stuff so it made it all the way to imaging before someone catches it.  It's a little maddening since our pre-flight is thorough and threshold = 0% or 100% K, not 99.....

I can adjust our temp map to light up 99% or less but I'd rather this get taken care of in PS v. making it to AI for final output.

It's really the same fight I'm having these days with really poor preview ability in channels.

Levels are your friend :)

A threshold at around 160-170 and there should be zero data under 100% though

Exactly, but if you can't see the random areas that are 1% under 100%?   Also have no clue why the threshold adjustment would leave 99% data behind.

The effed up part of this is that I want back into the file and did the threshold adjustment again and voila, all 100%.  That just makes my brain hurt.
