 Re: Questions about emulsion and plastisol inks
1. it depends, some emulsions have some more water content than others; overnight is safer, but if you have a proper drying cabinet, the time can decreas dramaticaly and in 1 hour you cand be good to go; generaly, i let the emulsion sit for 15 minutes, then use a domestic hair drier for about 5 minutes and then let it dry overnight.
2. plastisol doesn't air dry (like the ink from a fountain pen), it needs heat (350 degrees or so); anyway, it's a good ideea not to leave the plastisol ink in the image area of the screen; you can leave the ink on the screen and go for the week-end, come back on monday and still be able to use that ink, just agitate it a little with the squeege. (and cover the screen with a newspaper to prevent dust building up);
for the worst case scenario, there are some chemicals strong enough to wipe up a country from the map; ask your supplier |
