Inkjet printers use two different types of inks: pigment and dye-based ink. Although both can be used for fabric printing, pigment ink is better suited to print on fabric. Dye-based ink is less costly than pigment ink, but colors react unpredictably on fabric, and can wash out entirely when the fabric is washed.
Pigment ink, although more costly than its counterpart, is used to print on a variety of different surfaces and will give a better finish to the printer fabric. You can determine whether your printer uses dye-based ink or pigment ink by referring to the printer’s manual.
Physical examination of the ink can also be used to determine which type of ink is used by the printer. When the printer cartridges need to be replaced, remove a small amount of yellow ink and place it on a piece of glass. Examine the ink for color variations. Pigment ink that is yellow will be vibrant but opaque. Dye-based ink with yellow dye will be transparent and somewhat brown in color.
Note: Remember that when you are printing a design with white spots, the white spots will end up being the same color as the fabric selected because some printers do not print white. Although this depends on the printer, it is important to choose the designs accordingly.
