I've had good success photographing bromoil prints to reproduce them. You need a good copy setup (softboxes or diffuse light, like strobes though hanging ripstop nylon). The light needs to be even, so if it's a large print, you may need 2 lights on each side, or tall striplight softboxes. (I shoot a lot of paintings for artist websites).
To check for even illumination, meter with an incident meter all around the art work. To check for reflections, put something dark and shiny over the art, or a framed print with glass. Use a DSLR to dial it in if possible. I shoot with ilford Pan-F plus - if the neg is MF, I do two brackets back and forth til the end of the roll, cut off a few frames and develop those to check for contrast and highlight strength. Sometimes you need to pull or push a bit to dial it in. With sheet film, this is easier, and to save even more $$ I'll mask off half the rear standard with black cardboard, shoot, rotate the rear standard 180°, adjust bracketing and shoot again.
This is a standard copy setup for even lighting -
