A system for printing and emissive image on a substrate that includes red, green, and blue additive-color emissive inks configured to be printed to a substrate using an ink printer device intended for use with subtractive-color ink. An image to be printed can be converted to color negative form prior to printing using the subtractive-color ink printer. The system may include a subtractive-color ink printer intended for use with subtractive-color ink cartridges. The system may also include a computer device programmed to convert an image to a color negative form.
