screen printing > Newbie
Will white (low bleed) ink typically be heavy/thick?
Colin:
Actually Sonny, there are several different reasons why an ink will be tacky after flashing. None of them will have a direct corellation to heat.
Colin:
I should add that yes, depending, being to hot can make an ink tacky.
But even if the ink is right at flash temp... it can still be very tacky.
Gilligan:
Well, I'm DONE!
Whew... learned a lot I think.
I never could get anything close to a "one hit" white but I still used his "fill" then print technique... If I did it right and cleared the screen on both passes (pfp) then I'd get a pretty good feel to it... granted that happened like twice out of 36 prints (granted the hoodies were kind of weird to print on.
I also realized that I need to cheat the screen a little on left chest prints otherwise I get way too close to the edge on a little 20x24 screen.
I should have punted on that screen and made a new one but I just pushed through it. The print close to the screen edge ended up blurry, I assume from being so close to the edge amplified all the imperfections in my technique and made it that much harder to hit the same spot on each stroke. Though that is still weird since I was only hitting it once then flash then hit it again. I probably could have lowered my off contact to counter this.
Overall I give the job a C. The good thing is that it's my father-in-laws friend's company I'm doing these for. The bad thing is that their slogan is "We have an eye for detail"... oops. Kind of like "we are perfectionist" 'well, what about those shirts" "oh, well.. our printer isn't." ha!
Other good thing about the job is that we found out the wife can actually print with a 5" blade... so from now on she's on left chest prints. LOL Maybe I'll get some 12" squeegees and see if that helps on smaller prints. I found out that a 5" blade feels very flimsy and is kind of hard to print with actually. Is it common to up the durometer of the blade for smaller squeegees?
Also realized I want a dip tank! LOL

Hey Sonny,
actuallt the tac is, in my shop, is more a function of time under the flash as opposed to temp. The temp is pretty constant the time is my gut feel. You have to remember also i am in the frosty north and ink temps are all relative. Ink brands are a factor also, this just off the flash works the nuts on One Stroke Versamax inks which otherwise can be a pain in the arse other brands like Wilflex not so much...just sayin'

Colin and Mike. I get it. All I'm saying is that out of 11 issues when printing dark shirts 9 of them are TOO MUCH HEAT. Figuring out how to lower the heat is the test. Some suggestions...higher mesh=less ink. Harder squeegee=less ink. We want the ink on top of the shirt not inside the shirt. Have a great day guys, now go put some ink on underwear.
