Does Texcharge offer you a cmyk download? Its a little file that has the l.a.b. coordinates already loaded up. At the very least you will want to do a swatch test for each color and color overlap - then try your best to simulate/Sherlock your way into figuring out what that color space is by comparing the print to the visual that photoshop is giving you. Then you enter those values into your custom cmyk space.What are your dot gain settings? I would start at 40% and adjust from there. You may need only 25%-30%.... Try medium black generation. This will make some of your grays a blend of cmy.Other than that, what is you screen/mesh/squeegee/print set up?

My dot gain settings in CMYK are 38% for Magenta and Yellow and 40% for Cyan and Black - in the spot channel settings I have the dot gain set to 88% at 50%.We are using 120 mesh (Threads Per CM) yellow mesh, separations are done in Photoshop for four-colour process prints and sent to our I-Image direct to screen machine at 65 lpi with a round dot at 22.5 - this seems to be working pretty well for our simulated process prints but would you recommend changing for four-colour process printing?On press the Trichromatic inks are used straight out of the tub in Y, C, M, K order as recommended by Sericol with hard squeegees and at a minimum pressure but enough to clear the screen.
