SDIs Dust Removal System (DRS) is the ultimate tool for removing particulate contaminants. Unwanted particles as small as one micron are readily removed from your surface or substrate by simply passing the tacky roller over whatever substrate youre working with. Whether youre cleaning your work area, or a material you are about to print on (or both) the DRS roller is the way to go. The DRS roller has been used industry-wide for many years. Do you face mount photo prints to Plexi? You probably use a DRS roller. The light blue SDI roller is perfect for for inkjet-coated substrates such as art papers, photo papers, canvas, dye sublimation metal, and more. The DRS rollers have a 12" handle, are constructed of very high-quality plastic, and have a 30 degree handle.
