Looking for suggestions out there for aim point standards for density and dot gains for Flexo.
We have a customer that is fairly critical of color on their product as they should be.
We are a flexo shop that prints, die cuts, and laminates with a 2 Mil gloss clear laminate for this mentioned customer.
We changed our entire process for this, new materials, inks, etc. We ran a finger print of the new substrate and inks and all appeared to be well. That is until I found out they left out the part about going with the 2 Mil gloss clear laminate.
This is all done in line, so the pressman can easily obtain color retains of the control vehicles after laminate, not so much before, without stopping and starting the press again.
My main question as I fear, is, A. )The curve should have been made to incorporate a compensation for the laminate. B. ) Are the aim points recommended by FIRST to be matched on the actual printing or after the lamination. C. ) If the recommendation is to hit the numbers on the printing before lamination, what is the best scientific way to translate this for the press room to check density and gains after lamination. The easy thing I would imagine is to read sheets before and after, then publish the after aim points based on this. But I did not know if there was a better suggest.
Anyone else out there doing the same?
Thanks in Advance.
