As a screen printer, most of the work you’ll do is off-contact printing. That means a tiny vertical space is left between the screen and the pallet below. When you print, the squeegee pulls across the screen and provides enough pressure for the screen to come in contact with and evenly ink the substrate below. As the squeegee pulls away, the screen also pulls off of the substrate cleanly. The proper off-contact distance depends on many variables, from the ink you’re using to the type of material you’re printing, but the usual recommendation is to have as small an off-contact as possible. For t-shirts, the recommended off-contact is generally 1/16 of an inch, while thicker materials like sweatshirts have a recommended off-contact around 1/8 of an inch.

It’s hard to overstate the importance of proper off-contact. Without it, the quality of your finished print can suffer in a variety of ways. If your off-contact distance is too small, the screen will come in too close contact with the substrate. That can smudge and smear the finished print, or the screen itself can stick to the shirt. When the off-contact is too great, the print might look stretched, as the force of the squeegee presses and elongates the screen during the printing process.
Improper off-contact can give you a lot of headaches. It can cause the final product to be smudged or blurry; ink can be uneven, bubbled and blotchy on the shirt; and colors can fail to match up properly. It can be difficult to compensate for poor off-contact to get a final product you can feel confident handing off to your customers. If you’re not careful adjusting your off-contact, you can waste a lot of time trying to correct sloppy prints and waste a lot money throwing away misprints.
Correct off-contact is a matter of proper press setup. Before each project, the off-contact distance should be checked and set to fit the substrate below. On many screen printing machines, setting the off-contact is usually done with knobs or wrenches. It can be time-consuming, but it’s worth the effort to ensure you’re set up for successful printing.
