I am printing on material using Roland VersaUV running EUV4 Inks. I have a material that I would like to enhance adhesion and discovered a primer. However, I'm unclear as to whether I can use the cartridge. The Primer is EUV. Would this be compatible with my machine to use in the GLOSS slot (I don't use gloss). Roland does so CMYK, WH, GL and PR are available for EUV4...but this EUV PR is all I can find. I'm not sure if it's universal. Any help would be appreciated.
