Rowmark^® is a manufacturer that produces laser and rotary engravable laminate thermoplastic sheets, commonly referred to as engravers plastic or microsurfaced plastic. Common trade names for this material are Rowmark^®, LaserMark^®, LaserMax^®, LASERmag, UltraGrave^™, or LaserGlow^™. The substrate or base layer of the laminate sheet is composed of an extruded acrylic resin. The acrylic resin layer is composed of a copolymer emulsion of ethyl acrylate/methyl methacrylate, acrylic-styrene copolymer, methyl methacrylate and ethyl acrylate. Additional additives can be included with the base resin such as processing aides, impact modifiers, colorants and color additives having heat stabilizers that facilitate a maintaining of color intensity under elevated temperatures. A cap layer of the sheet is added in the form of a recyclable metallic hot stamp or colored acrylic. Laser processing of Rowmark^® can be done with either a 9.3 or 10.6 micron CO₂ laser without a noticeable difference in process quality. Laser processing of Rowmark^® with a 1.06 micron fiber laser has the potential to create a surface mark depending on the dyes, pigments, and polymers used in the top engraving surface of the material. Laser cutting of Rowmark^® with a CO₂ laser produces a clean cut edge with slight tackiness depending on the specific type of material. Laser engraving of Rowmark^® with a CO₂ laser results in a smooth, clean ablation of the thin top layer on the material, revealing the underlying substrate. Laser marking of Rowmark^® is limited to use with the 1.06 fiber laser and will produce a contrasting surface mark depending on the dyes and polymers used in the top layer.
