Black ink first

[Pangea]

We have a job coming in that's basically a big black circular shape with white lettering inside of it. Rather than trying to knockout the white to print it first would it make sense to print the black as a solid shape, flash then p/f/p the white over top? I've done this with a bleed blocker base before but wanted to get other opinions before burning screens. The shirt color is sport grey otherwise I would probably do it a different way using discharge.

You should be able to run it with the black first, but there is no need to make it solid under the white.

I agree with Sepsink, black first then white, your asking for trouble printing a solid white over a solid black base, ink not adhering, smearing of the edges on your white, black ink could bleed thru your white etc

Awesome, good to know I'm on the right track. The white is thin lines and pretty basic text, not much at all so I may take this as an opportunity to try it out two ways and see how they differ.

watch your flash if you do print black first, we have burnt up a few too many garments doing this. black ink heats up real fast and usually melts on things like triblends....

We'd print black first, with the white knocked out. one or two screens for the white if needed. We would not flash the black to underlay the white, that would be for a an extraordinary situation.

Knocked out the white and put a very thin stroke on the black (my press is a 20+ year old Atlas with not great registration). Printed black, flashed, printed white, flashed, printed white again. Took way too long but it's done, delivered and billed.

Looks great! You could probably avoid the 2nd flash with s mesh. One hit white all day long with good EOM and those thin lines.

We will often print black first, then white, flash and top colors WOW on the auto. Biggest issue is buildup with the black after a certain number of prints. Might be the synergy black we use, that stuff will build up fast an very thick... like several mm’s thick. Not fun to wipe down a base screen with a large patch of black on it... but 300 pcs & under we usually do okay without having to do that. Anybody good a good tip to avoid buildup on the base screen when printing black first?
