Ink Problems? Newbie

Posted on Mon, 23 Feb 2004 at 16:43



Yesterday I tried making my first shirts. It went badly. I was printing white plastisol on old black shirts but the ink was coming out unevenly. Sometimes it was way too thick and other times it wasn't passing through the screen at all. I think the screen was getting clogged. Should I use a thinner on the ink or is there something I'm doing wrong in the application?

What mesh are you using? 110 works well for white. Too fine a mesh will give you trouble with white. I use a squeegee with a sharp edge. If the squeegee is bending excessively, you're not printing with the edge and need a stiffer squeegee. I use a 70 durometer or a 60/90/60. Angle the squeegee back toward yourself about 30 degrees and push it away. If the ink is thick, you can thin with the thinner recommended by the ink company. You're not supposed to thin with mineral spirits, but if you try it, try it with a small quantity of ink so you don't ruin a whole gallon. I wouldn't make a habit of it, though. If all else fails, get a quart of another kind of ink.
Good luck,
Paul

Paul,
Thanks for the tips. The screen I'm using is a 110 mesh count but the squeegee I'm using is only 9 inches. I have to make two passes to cover the whole image. Should I be using a larger squeegee? I'll try the mineral spirits idea with a small amount.
Thanks again,
D.Sousa

White ink is hard to print, especially for your very first project, but you can get good results if you are patient. First, the ink (especially white) has a "false body" which means it gets stiff when you're not using it. To break down the false body, stir it vigorously with a stick for a couple of minutes. Then as you're printing, work the ink back and forth with the squeegee often to keep it soft. With white I find I need to make two, and sometimes three passes, flashing in between to build up a nice opaque layer of ink. If you must reduce the ink use a curable reducer rather than mineral spirits and just use a tiny amount (2% by weight).

i also have a question about ink. i am literally screening for the first time and got the emulsion part fine (after a few tries). but, my question is, what is the "correct" way to do the actual screening part? where do you first put the ink? how much ink? which way do you run the squeegee? ive screened about 6 shirts now and all of them have come out differently. most have areas that are too light and some have areas where the ink spread a tiny bit (i guess i put too much). is there a fool proof way to get it right nearly every time?

thanks.
