Single Process Printing Versus Double Process Printing

Zazzle uses a DTG (Direct-to-Garment) printing process to produce each shirt. Our light color apparel uses single process printing, while our dark apparel uses double process printing.

Single Process Printing: The color white is not printed on our light colored fabrics. Any white used in the design will come across as transparent allowing the color of the fabric to show through.

Double Process Printing: Dark color apparel has an upcharge due to the extra process of printing a base layer of white ink under the design to make it more vibrant.

Even though the design is the same in all three shirts, note the color differences in Mickey’s face. In the two light apparel t-shirts (white and light blue), no white is actually printed in those designs (single process printing) and so you’re seeing the fabric’s color filling in Mickey’s face. In the dark blue t-shirt, you’re seeing the undercoat of white that was initially added to make the design more vibrant (double process printing).
