Pre-treatment roller set (optional item or commercially available)
A paint roller can be used to apply the pre-treatment solution to the T-shirt, and makes it easier to
apply the solution to uneven areas such as pockets. The tray is used to allow the pre-treatment
solution to soak into the roller. Choose a paint roller made of short polyester fiber with excellent liquid
absorption and release, and one whose handle is made of rust-resistant aluminum. Use a tray to
allow the pre-treatment solution to soak into the roller. When using a paint roller, make sure to apply
the pre-treatment solution evenly, or the white print quality may not be as bright or printed colors may
appear distorted. The optional pre-treatment roller set includes the roller, handle (roller grip), and a
tray. If you don't have the optional set, use a different paint roller for each color.
Distilled water (commercially available)
Distilled or purified water is used to dilute the pre-treatment solution and to clean sensor covers.
Pre-treatment machine (commercially available)
A pre-treatment machine is used to spray the pre-treatment solution onto the T-shirt. Using a pre-
treatment machine is quicker and easier than using a paint roller; however, more of the pre-treatment
solution may be used because of overspray. For best results, we recommend an electric sprayer that
allows you to spray a fine mist. Check in advance if the solution can be applied properly according to
the pre-treatment solution and pre-treatment conditions.
Sticky tape or lint roller (commercially available)
Use sticky tape or a lint roller to remove lint from the print surface of the T-shirt. Take care not to pull
fibers up from the T-shirt.
Hard roller (optional item or commercially available)
Use a hard roller to press the fibers flat on the print surface of the T-shirt before printing. Make sure
that you prepare a separate hard roller from the pre-treatment solution roller.

Pre-treating a T-shirt
If you are printing with White ink on a cotton T-shirt, or printing on a polyester T-shirt, pre-treatment
solution must be applied to the T-shirt.
Follow the instructions in these sections to prepare your T-shirt for printing.
Note: When printing with color ink on a cotton T-shirt, we recommend that you do not perform pre-
treatment as printed fabric can become too delicate for washing and rubbing.
