This article explains how to print with white ink and what alternatives there are to printing with white ink.
Screen printing with white ink for beginners, step by step.
Epson sells a white ink cartridge for use with its inkjet printers. This option may work for small print jobs on your home printer, but the cost of the white ink cartridge is much higher than typical ink cartridges.
Approach the print or design project from a different angle. You can print the dark color with the type reversed on white paper, meaning that when you want an element to print white, you reverse or “turn off” the white type or element from the background. No ink is applied to the area where you want white, only around it as a background. In essence, “printing in white” is the absence of ink.
If your design has white elements, for example a white heart on a red background, only the red will be printed and the white heart will be the paper showing through. This option is much cheaper to print. Of course, this method will not work if the paper you are using is not white.
