The purple colors are made from midtown (40-50-60%) areas of Mag/Cyan, they are the most difficult to control because of dot gain. i would measure the mid tone gain of your “good” profile sheets & compare the gain of your current sheets. You will have to add a color bar that contains Solid&50%...

Another thought- compare several sheets, notice any ‘doubling’ or distortion of any of the dots? i had a similar problem with a 2-color screen job - it was dot shape - changing the tonality.

So right Gordo - I would meet with the print shop owner and my first question was “how much is budgeted for training”. I have NEVER had an owner tell me he had a budget for training. When consulting the owner would ask me “how much money will you save me?” My response was always - “how much are...

I’m a big fan of Mr. Demming as well. No one in the U.S. would listen to him, not even GM! He said “you don’t inspect quality - you produce quality!” I have the same respect for Felix Brunner, he contends you can’t control color on press with Lab controls - see attached. Few listen to him either...

This is a problem I run into often. The previous operator had all the knowledge and seldom shared his information. If you like you can call me to discuss your situation. I was a consultant for the only printing company to win the Malcolm Baldridge Award. It was Branch Smith in 2002 of Texas. I...

The "correct" color sequence after testing by PIRA and others is K-C-M-Y or C-M-Y-K (Black can be first or last). The reason PIRA explained is that the 'Red' (color) trap is better with M-Y together, and humans are very sensitive to the color Red. If you put C-Y together then the 'Green' would...

I agree that 200- 250 is very reasonable. Does the pressman print to gray balance? I helped Life Touch years ago - their make ready was around 300 sheets. (some yearbooks were only 150 copies) I created plate curves based on gray balance and they told me their make ready dropped to 100 sheets -...

>>>>>I have a couple - check water temperature at pan and roller temperature - cooler may help. I would try another ink set, maybe Wikoff (they have a heavy pigment load). The most expensive item in ink in the pigment. When consulting I asked the ink companies "why" they don't list the pigment...

I've always wondered - what 'standards' are the Pantone books printed to? What are the tolerances? I personally won't trust any printing without a color or gray bar to measure!

By far Felix Brunner.

Here's the simple answer (I hope) - In the beginning . . .film was produced linear, plates were exposed - a 50% dot became 54% on the plate (in a good shop - "others" it became 60% or more .. .). When printed at correct density, on a press set up correctly (rollers,blankets, pressures, etc.) the...

print contrast print contrast GATF described print contrast as a value of 75% screen tint (film/CTP or otherwise) and solid. The late Ken Rizzo (GATF) measured the higher density of magenta in G7 sheets and noted that the print contrast value dropped when the density reached 1.50 (The 1.44...

You should print a GATF test form with "ladder bars" to be sure there is no major problems. Dan Remaley 412.889.7643

dot gain or LOSS! dot gain or LOSS! Creo was the worst! Your right Creo wasn't thinking of film OR the correct value, they were only interested in the correct 'exposure' for their positive plates. EVERY Creo shop that I visited, using positive plates, measured the 50% patch near 45-46%! The...

Dot Gain Dot Gain Here's my take on this issue- the Pantone screen book isn't printed to any standard AND it doesn't have a nice gray color bar to confirm that it's printed correctly, book to book page to page. My old book had some density/dot gain numbers (AVERAGED) that were 'near' SWOP...
