If you are printing a picture that is dark, purple, blue and red on a pink shirt, you can utilize light pretreat and no white. If the picture is yellow, lime green and sky blue on a pink shirt, it would require dark pretreat and white ink.

Dark Pretreatment

Another method you can use to pretreat shirts before DTG printing is Dark Pretreatment. Dark pretreatment is an unexpected equation in comparison to light and plays out a couple of more tasks. The main functionality of dark pretreatment is to make a surface that white ink can be imprinted onto. Without pretreat, white ink would assimilate into the texture.

When printed, the white ink lands onto the shirt and begins to gel up when in contact with the pretreatment. This prevents the ink from remaining wet and forming bubbles giving the color ink a surface to print on and not drain or blend. When the shirt is placed in the heat press, the heat activates the pretreatment as a bonding agent so the print can get into the fibers and wind up one.
