Permaset Aqua Print Paste (Extender)
This can be added to any Permaset ink (or any waterbased screen printing ink, really) to lower the opacity of the ink. The more you add to the ink, the more transparent it will be when printed. This is great for doing overlapping colors or for doing tonal prints. This is a curable extender so you should be able to add as much to the ink as you want without affecting its curing properties, but as always, wash-testing is recommended before large production.
