Hello! New to the forum, long-time screen printer here. I'm wondering about Inktech's Satin Poster series. I've inherited a gigantic quantity of the stuff and it's been stashed away in storage for a few years; it's become quite thick (I remember when I first got it, it was pretty loose).
I know you're supposed to use their brand of thinner for extending/cleaning, but what terrible thing would happen if you just used paint thinner/varsol/turpentine or the like? Just curious. If anyone who has experience with this brand of solvent inks could give me some advice, I'd appreciate it.
