    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...

    tone value increase

    TRUE but - 2 reasons - #1-I don't trust Creo or Kodak and I want to be sure I'm printing a 1-2-3% dot accurately! #2- When the bean counter up front decided to change plates all I need to do is linearize - curve stays the same! Oh, and by the way, on a previous post you thought on a negative...

    tone value increase

    Here, try this and let me know how it works! 1-Print this tone scale with linear plates (attached). Use "Deer" poster for density reference Coated & Uncoated! 2-Measure dot area. 3-Enter "Wanted" values into rip (no one ever gives you them) (attached). 4-Print with new adjusted plates. Oh, you...

    Trouble color matching blues & purples - offset CMYK, G7 methodology, GRACoL 2013

    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%...

    Unable to achieve a flats seamless grey with CMYK

    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.

    PIA’s 2018 State of the Industry Report

    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...

    PIA’s 2018 State of the Industry Report

    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...

    Color Management Training

    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...

    printing sequence

    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...

    Issue with operator

    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 -...

    Consiistent-excessive dot gain/TVI on all units.

    >>>>>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...

    Pantone and CMYK - How To Ensure Desired Color?

    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!

    Who was the Greatest Person in History of Printing?

    By far Felix Brunner.

    Why is the target not linear?

    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...

    Press Dot Gain help please!!!!!

    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...

So You Want to Invest In Inkjet

I Want to Invest in Inkjet, But…
Over the past few years I’ve watched a group of transactional and direct mail printers strategically shift from monochrome toner machines to full-color toner and inkjet presses. Most banished old black-only toner boxes but kept their color toner devices around because they anticipated needing both color inkjet and toner presses to meet customer needs. They were right then and continue to be right today. Because toner and inkjet can be better together. Read the Post
