Please find some links and notes from the 2 Regular Guys Podcast. This week, our guest will be Brian Walker, a pioneer in direct to garment pretreatment and inks. Brian has been in the industry since 1986 and will talk to us about where pretreatment and DTG printing is going. Brian will also be sharing his latest venture, garments that are pretreated when you buy them.
Coated and Uncoated Papers in DTG Printing – Sometimes we have to stop and look at our procedures and see if anything has changed with the component parts. Too often, we continue with a method or technique because “that’s the way we’ve always done it.”
We have until recently used uncoated paper between a pretreated shirt and the heat press to protect the heat press and dry the shirt. We used uncoated paper because silicon coated paper cause the shirt to be still and shiny. We then used silicon coated paper between the printed shirt and the heat surface to cure the ink. The silicon kept the ink from sticking to the paper.
Today, you can use silicon paper for both steps. This allows you to stock only one paper, and not stand in front of your heat press trying to determine if the paper is coated or not. With advances in pretreat solution, the glossy finish (when applied properly) is no longer an issue.
Pretreatment Methods for DTG – Best to Worse If it’s in your budget, buy an automatic pretreat machine. This will give you consistency with this critical step in the process. Be sure to check max pretreat area matches the potential print area of your DTG machine. Also check that the spraying process is completely enclosed. If not, be sure to spray away from your DTG machine.
