Velum is not velum is not velum. Same with ink. There are plain velum papers made for printing, and special velums made specifically for photoresist for screenprinting.

Note that they sell a black photo (dye) ink made specifically for this purpose, but as you'll see in my other response, it isn't necessary if you don't use black.
Some Epsons use dye, some pigment. Some use a dye black that they call photo black and a second pigmented black for text printing. Some Epsons are all pigmented inks, some are all dye. Many Canon printers use dye for colors and a pigmented black, some add a dye black for photo black.
So it isn't enough to ask how an Epson or Canon printer works for transparencies for photoresist - which model? OEM inks or aftermarket?
