Hey everyone i am having a lot of trouble with putting white ink on some black shirts. the white is coming out somewhat blotchy looking not a very thick whits and u can still see some black underneath. i used a 160 count screen and a 85 cound and both seem to come out the same... what am i doing wrong?
had this same problem last week, consulted these forums and received some very useful information. question, do you use any sort of off-contact? i usually tape 2-3 pennies to the screen so the mesh doesnt rest on the shirt, and thus pull ink off the shirt when you lift the screen up. anyway, for a thick, opaque white on a dark shirt you want to fill the stencil with ink prior to placing the screen over the shirt. then, with the stencil completely filled with ink, drop the screen over the shirt and hit it with 1-2 passes. check out this video, this guy is legit...
after utilizing this method almost all of my white-on-dark prints were lookin frosty..and by frosty i mean white as snow..crisp, clear, and bright. hope this works for ya
thanks i will try that tomorrow when i get back to work. it looks like it should work good. Do u tape one or two pennies on each side of ur screens fr distance? i would assume one??
hmm, im confused by your last question. i stacked 3 pennies together, then taped them to the middle of the frame of the screen, it kept the mesh from resting on the shirt, which is most likely part of the reason why your ink looked thin. im guessing that some of the ink was pulled off the shirt due to the mesh sitting on the wet ink
Try switching to 110 mesh tightly stretched. Then make sure you don't have a polyester bleeding problem by doing a test print on a 100% cotton black shirt and see if the print looks the same. If these are 50/50 shirts you will need to use a good quality "Low Bleed" plastisol like International Coatings 711LF White.
