Using Print Materials Using Your Printer adhesives are semi-liquid and may contain volatile components that can cause printer contamination or fumes when the adhesive is heated or placed under pressure. Zone coating (or zone printing) of the adhesive involves placing the adhesive only where needed. Zone coating is generally used with paper labels and integrated forms. A no-adhesive border of 1 mm (0.04 in.) around the outside edge of the label sheet generally gives good results. Check with your forms supplier to determine whether selected labels are appropriate for your printer. A stripped edge matrix of 3 mm (0.125 in.) along the outer border of the label sheet, combined with a tight adhering adhesive that does not ooze, may prevent glue contamination. This design requires a stiffer backing material to prevent crushing when the sheet is aligned on the reference edge. Generally, vinyl and polyester labels lend themselves to this design with few problems. Paper and dualweb designs require some testing to determine which backing produces good results. Finally, make sure that the adhesive has pull strength adequate to prevent label peeling during printing. Adhesives must be able to withstand pressure of 25 psi and fuser temperatures of 212°C (414°F) without creating hazardous fumes or oozing from edges of labels or die-cuts. Contact your forms supplier for additional information. Face Sheet (Printable Stock) Paper, vinyl, and polyester are the major printable stocks used for labels. When using alternate face sheets, your forms supplier can provide information on whether the stock face can withstand temperatures of 212°C (414°F) and pressure of 25 psi. You should test the stock to ensure it works satisfactorily with your printer. Using Print Materials 133
