Attached is a way to print to grey balance at press. Measurements are Status 'T" and absolute (including paper). Call with questions:412.889.7643....
Here is a way to develop plate curves for the press. The pre-press rip must have 4 channels Y-M-C-K. Email me for more information....
Start with a good 'Color Bar' that has solids, 50% - 75% patches and a Grey patch of 50C-40M-40Y - next to a 50% Black (for visual reference). Now...
Density is usually measured "absolute" (including paper) and in the U.S. - Status 'T'. Run sequence is K-C-M-Y (Black can be first or last) -...
Here is a quick and easy way to print to Grey balance at press (you'll need help from pre-press though). You can change the "wanted" numbers for...
IF the inks were "pure" (Magenta is the problem) and reflected correctly then y-m-c equal values would work. Since they don't Cyan is always...
I have a couple conventional UGRA plate scales - if anyone needs? $50 each. Works with traditional positive/negative plates. danremaley@comcast.net
Even if the density is "correct" the dot gain changes will change halftone images. Be sure you include Solid/50%/75% in the color bar. 50% is to...
Attached are some items that you may find interesting- especially the Brunner Stuff! Ever wonder at press, why most of the images look good except...
I found this old poster that has some information (attached). I also have all the dot area values for the entire tone scale - call me if you like...
What are the values (y-m-c) in these black areas? 1- you could convert to Medium GCR to remove or reduce y-m-c values. 2- change y-m-c values to...
. . . Did you know that you can measure the 50M/40C/40Y grey patch as a ‘density’ and know everything about your press sheet? Set you densitometer...
Here’s my take- All of the ‘color decisions’ are made prior to press! Pre press separates the image and decides grey balance & dot gain....
