Mix some "glycerine" in with your ink.
Can you please elaborate on the 130F reducing coagulation? Would you have an estimated time, or a calculated range, before inks on screens, above 130F pallets starts to clog? What type of WB inks has acrylic formulas and which does not....
Believe it or not, printing with warm pallets (130F) can also aid ink flow and reduce coagulation with the Acrylic formulas that are commonly found.
I never really paid attention to that bec I heat-cure my prints but based on your quoted description it does seem to prolong the curing time. However the main use of fixers is for color fastness and not for reducing or increasing curing time. If it does indeed increase the curing time then it is just a side effect of the additive."Tulco screen printing supply" describe fixer UR & UX as "A self curing additive that allows the inks to cure within 72 hours without heat curing. Although heat is not required, curing at 150ºC for 15 seconds or more will result in a reduced setting time"
my question is, is it prolonging the curing time or shortening the curing time?
If my house is on fire I'd be more worried about overcuringOne of my books suggests using plastic wrap over the screen if, for instance, you suddenly have to run to the bathroom, or the house is on fire, but I haven't tried it yet. It works well for latex paint if you wrap up your brushes in it overnight and put 'em in the fridge, so I guess it's worth a shot in a pinch.
