Question for Dan the Man

(1/3) > >>

inkman996:
Hey Dan I have a job coming up that uses three colors red/kelly green/yellow. I want to create a fourth color out of the red and green. What i am hoping to do is get a good darker color than all the rest, i never did it with a green and a red in the past. What would you recommend for parameters. Solid on solid? Halftone one? 110's screens? red on green or reverse? I am assuming the color will be some what of a muddy drab green?

can I play, too?

here's my guess . . . Dan tha man can correct!

red and green mixed should give you a brown. If you are just looking to darken up the green and you are using a darker red, I would print a solid green with a very fine halftone of red on top. 20%? Maybe less . . .

For spots, we would use 230's and if it is a raster type image with photo type gradients, it would go on 305's. Yellow first, then solid green and little bit of red on top.

this also changes depending if you are printing on an underbase or not. Total ink that can safely be deposited on a light color shirt is higher as the cotton will soak it p. When printing on an underbase, the ink stays on top of it and only about half the qty can be laid down safely. In some cases the green might not be 100% but 80% or so (if there are other colors going into the mix). From what I am understanding, on cotton 250%+/- works, on underbases 150%+/- is OK (or you can think of it as 150% plus underbase has to be less than 250%).



here's an approximation of the results . . .

You have the same thoughts I had. But needed to be sure. The image is all spot colors so mesh counts probably 160 or 200. I figured solid green and some percentage of red on top. Colors are not specific so i am going to use a darker than flag red for this print.

Thanks!

with or without the underbase?

JBLUE:
Heres my two cents even though it is not even worth the two pennies. If this is a job that you have time to play around with I would play with the percentages and see what you get on press. Its a great way to learn what you can pull off. If it is not just bite the bullet and throw down the fourth screen for the color you need. It will take less time to do that then it will to re burn a screen, new film, set it up again and trying to dial in your percentages. Those two colors together get pretty nasty looking quickly if your off.
