Laser printers and copiers work through an electrostatic digital process that produces high-quality materials. TESLIN® SPID substrate is a coated version of Teslin SP substrate designed for tray feeding in laser printers and single color copiers that use fuser oil. For such printers uncoated Teslin substrate thinner than 10 mil (254 micron) is not recommended, as multiple feeds are common if tray feeding is attempted. In oil free laser printers, Teslin TS range can be used. Some loss in lamination peel strength with thermal laminating films is noted with toner imaged Teslin SPID substrate.
In laser print applications where registration of the toner image with preprinted information is critical, either Teslin SPID or Teslin TS substrates are recommended. These materials have been stabilized to limit shrinkage to < 2 percent.
In a pressure-sensitive format with the proper adhesive and liner, Teslin SP grade can be fed in laser printers. In the pressure-sensitive format, the release liner provides adequate sheet-to-sheet slip for successful tray feeding. The proper pressure-sensitive adhesive must be specified to avoid adhesive squeeze-out at sheet edges, which can lead to adhesive deposits on the transport surfaces and internal jams.
Teslin substrate has been imaged in certain models of Canon, Xerox, Kodak, Konica Minolta, Lexmark and Ricoh color copiers and printers. However, equipment options in this field change rapidly. Teslin TS and SP grades also have been successfully imaged using machines that use minimal or no fuser oil.
