Did you know that not just anyone can reproduce a UL mark? UL requires every mark to be printed by an authorized label supplier. Dion Label Printing is an approved UL printer and can reproduce their logo on a variety of substrates (refer to our listing: PGAA.LP1597). In addition, we partake in the PGDQ2 program at UL. The PGDQ2 program allows Dion to offer a variety of proprietary products which are tested and approved by UL under your exact substrate and temperature requirements. You give us the parameters required, and we will determine which of our product fits for your application, or please see our DLUL product line at www.ul.com under UL listing number PGDQ2.MH29628.
