Title: Discharge cool grey
Post by: Pangea on January 05, 2018, 12:56:02 PM
I just got an order for some light pink, sky and orange tees with a print using cool grey 9. The main reason the customer came to me to, possibly, replace their current printer is because I run water based/discharge ink and they want a nice thin print.

Would you guys run this with discharge ink or stick with a straight water based?

Assuming that the shirts will all discharge, won't that always result in a thinner print with softer hand?

That makes sense to me, I don't print gray too often and never think about that color being more of a white then black ink.

They have a B rating on the Gildan discharge chart so they should be fine. Thanks!

Straight WB would actually give a softer hand. Activator can add a bit of stiffness, though usually negligible.

Cool grays can actually be kind of tough. Reason being that you are essentially discharging all the way to greige
and then dyeing back to cool gray. And greige tens to be warm, particularly on your pink and orange.

Either route you'll want max pigment load.

In the long term will it? In my experience after washing the "crust" from discharge disappears but straight wb is forever.

What do you mean by "max pigment load"? I plan on following the Matsui CMS for the color match and that's a very exact ratio (white to black pigment). If you're referring to activation rate what percentage would you suggest?
