    Gcr for pdf

    Here’s my nickels worth- GCR affects all tri-chromatic colors (Y-M-C). The ‘graying’ component of a color is reduced and replaced with black. I.e. “reds” graying component is Cyan. Blues graying component is Mag. GCR - “pushes” the tone scale to be more saturated or less saturated in the...

    Gray Balance consistency run

    Printing 50/49/40 is impossible! These values are at or near the midtone area - where the midtone dot gain changes under the best conditions (+/- 2%} is the standard deviation of a good press! So as long as these gains climb together- you get a ‘darker’ grey - when one goes up or down relative...

    G 7 certification

    “If you imaged plates from linear film and printed using ISO conforming ink hues to the specified densities then you would automatically achieve grey balance. Great” No such luck! The dot gains make grey balance (at density). The proofs were Matchprint SWOP. At density the midtone gain was...

    G 7 certification

    So here’s a little ‘history’ of color reproduction. In the ‘old days’ we had ‘trade houses’ which produced color separations for the printers. I was one of those - so how did we know how to make the separation’s? We made them all to SWOP - (Specifications for Web Offset Publications) - based on...

    . . .a great story-I did some consulting for a company (Branch Smith) in Texas. They won the prestigious Malcolm Baldridge Award - I believe the ONLY printing company to do so. While there I found several issues, a big one was the press was ‘doubling’ in the Magenta Unit - I called and asked...

    Disappearing dot gains?

    I’m thinking something in the RiP got corrupted. . . Maybe reset it & re-liberalize. Press ALWAYS gain - seldom sharpen. I have the RiP “wanted” numbers if that helps. Dan 412.889.7643

    I have instructions on how to achieve Grey Balance at press. This will work for single, 2-color, & 4-color presses. It's designed for people who can't afford, or don't have the tools necessary, for G7 or other methods. I have density numbers for Coated and Uncoated as well as the "wanted" RIP...

    Felix Brunner Items-

    Here's an item I wrote several years ago and the responses. The standard deviation of a press is + or - 2%. That 4% variance in any particular color will show a cast but if you keep the colors in 'balance' the 4% variance becomes only a 'light' or 'dark' variance - this difference we can live...
