Looking for some pros and cons of printing 10 micron. Are there any benifits as far as color holding better on press ? Or is it more for the detail it holds ? Any info will be greatly appreciated.
1st-order FM can appear grainy in large areas of flat color - say a big, blue square. 2nd-order is supposed to remedy that, but I've not had the opportunity to work with 2nd-order stochastic.
WOW! I like the response. No we do not use this in our everyday work flow. We have tested 20 micron. Yagger or anyone, can you share the optimum press conditions you speak of ?

I can only express a opinion of what I have experienced in a real life production environment. In regards to printing cereal boxes, I imagine any colour analysis over time on those sheets (if any is done at all) would show a fluctuation from the original calibration, especially printing on Packaging board.
I guess its horses for courses, packaging is tight margin work, as long as it looks good, bright etc, then run. The work we print is high end of the market and really did see a change. Im not saying its down to FM print completely, but the current structure of our business, meant we couldn't run FM effectively (as we did before).
We are running a stable hybrid screening with a great print result, so a great business decision.
In June I went to the Heidelberg Factory in Germany, what great experience. The General attitude to FM, was the experiences I have found up to that point. Obviously they were 'Biggin up Hybrid !!!', but the results I have seen to have backed up what they said.
Hello Sirs,
I am a print manager of a CD102 brandnew. And I am facing to a problem of gray tone. Could you please spend sometime to read and give me some advice?
when I print a gray tone with AM, there is color variation between sheet and sheet. There is no doubling and slurring on it. The color variation is not much, delta E is below 1 but easily recognized by eyes.
After reading your comments in this topic, I found that FM could be solution. FM is more stable than AM. Please tell me which point of FM is more stable than AM? Dot area? Gray composition?
Many thanks in advance!
Regards,
Delta E
Thank you Mr. Gordo!
That's the thing I am trying to use GCR to apply on the image via Photoshop.
When I check on PDF file (the file for plate making), I can found that separation value of the gray area is changed from:
C 49%, M 35%, Y35%, K 0%
to
C 29%, M 15%, Y 12%, K 38%
I will try on press tomorrow with this new separation!
But do you think that the image looks much different with the new separation?
Thank you for you very fast and very kind reply!
Regards,
DeltaE
