What Is White Ink Printing?

White ink printing is simply printing with white ink on a clear or nonwhite background. This technique is commonly used as a base layer beneath CMYK ink, but it can also be used to create high-contrast black and white designs.

Cyan, Magenta, Yellow, and Black are the four ink colours that printers mix together to create a specific colour. Because CMYK inks are incapable of producing white, white ink must be added during the printing process. Aside from the ink, specialised software is needed to control how the white ink is printed.

When white ink is used as a base layer, the CMYK ink colours are brightened, making your graphic designs appear more vibrant and accurate. This is especially useful when printing on off-white or uncoated paper, which partially absorbs ink and may change the colour of the ink if there isn’t a white base layer.

There are two main methods for printing with white ink, whether as a base layer or as the primary colour. White ink can be used as a spot colour by applying it only to specific areas of the material, or it can be used to fill the background, which is known as flood coating.
