Of course, what we are applying the pre-masked metallic film to are simple rectangles of acrylic, and then the laser cutting is done after the film is applied. Orientation of the metallic brush pattern must be kept in mind so that all the parts reflect light in the same way once in place on the client's wall. If high-performance vinyl film is to be used to add color or details to our letters and logos, it will be plotted out and ap- plied to acrylic parts after they have been cut. This way the laser is never used to cut through vinyl. A lot of our acrylic letters and logos are not covered with any film, but the factory masking on the acrylic is left in place, or a new layer of transfer tape is applied before cutting on the laser. The paper pre-mask is dampened with water right before cut- ting so flame damage by the laser on our cut parts is greatly reduced. On occasion, if thicker acrylic is need- ed than what we have on hand, we may bond two thicknesses of acrylic sheet to- gether, covering the parts with a thin coat of acrylic glue as a laminating adhesive. Typically, we mix the water-thin acrylic glue with the thicker version in about a two to one ratio. When doing this, the blank sheets are kept small, coated with glue, and then weighted down for several minutes while they dry. If the bond is tight and even, there will be no voids in the lamination and the cutting will produce a fine, clean edge almost as if the parts were made from one thicker piece of acrylic.
