Screened Adhesive can be a problem solver for your custom heat transfer business. We at 1st Street Graphics have been successfully using screened adhesive on transfers for custom printing uniform materials such as dazzle cloth, performance wear, polyester (tight knit to tricot mesh) and reversible mesh jerseys. When applied correctly the prints will successfully adhere to these fabrics and handle multiple washings. With the addition of a screened adhesive you can also avoid most ink migration from the garment dyes up through the design. We recommend application at 60 lbs or very firm pressure and 375 degrees for 5 seconds for most applications. In all cases it is wise to test the printed product to be certain that the design is firmly applied to the garment. Remember you are actually gluing the ink to the garment instead of embedding the ink in the fiber of the garment. Always cold or warm peel your transfer after application. You do not want to hot peel and possibly split the inks in the paper removal process.
We have successfully used adhesives on uniform products from Badger, Teamworks, Augusta, and A4. The adhesives do not work consistently on tightly woven fabrics such as polyester wind shirts or nylon jackets that are design to be wind or water resistant.
If you are using heat applied numbers or names on the same side of the garment you must print the custom design first before lowering your temperature to accommodate the heat applied vinyl numbers. Covering the printed design with a Teflon sheet will protect it during the numbering process.
One of the other invaluable uses for adhesives is when you are needing to print
very fine detail. Because plastisol ink is re-melted and embedded in the fibers of the garment during the application process, finely printed details do not adhere well. If you add a clear adhesive you will not have this problem.
