So, it's an expensive practice. $400 (a box of 11x14 print material and 4L of chemistry) might get you four 10-print editions, if you aren't wasting a lot of printing material to get to your perfect print. If you don't need so many copies, you'll get more, of course. And don't forget the cost of the masking film, at over a dollar a sheet.
Apparently surfaces other than glossy are still manufactured as well, but they are only sold in large quantities to professional labs, so home users are out of luck.
