I received a question about filling the Riso ink tubes with alternate inks, but I have no idea what the properties are for Riso ink, and I'm curious. The client asked about using offset inks or water-based acrylic inks. Is anyone familiar with non-oem inks or mixing inks by hand? I understand that it is not recommended to run different inks through the drums and that Riso's oem inks work best. The client is running prints on an RP model, but I'm assuming it could apply more globally.
