I've been using RC paper, it's all I've ever used, and I have a print dryer with excellent canvas. Will it still curl with a print dryer?
As for a print washer, I've been researching the DIY threads. I think I'm going to outfit a 10 gal aquarium with some intake and outflow hoses.
If you get serious about a DIY print washer, let me know. I have experience and have added some touches not found on commercial units. Won't go into details on this thread, though.
