Exactly as I have been thinking to myself silently, which is why I've been latching on to every piece of info I can find about color separation, bromoil, dye transfer printing, and home-made coatings I can find.
Kind of a bummer that as soon as I get the kid out of college and have a few spare bucks for myself the hobby I treasured as a kid begins to fall apart.
So, if I have to make glass plates, then I'll make glass plates. If I have to hand coat paper, then I'll hand coat paper. If I have to boil plant stems or grind rocks to get my own color dyes, then I'll boil plant stems and grind rocks. But I've been waiting 25 years to get back into this, and no mere lack of commercial materials will stop me, regardless of what compromise must be made in the product.
