A&E OCTOBER 2018 • a-e-mag.com 19 Learn how to produce a modern and elegant holiday card using your laser to engrave and cut a simple piece of paper. Materials Needed: • Paper (anything goes, but you will get the best results using paper with a weight of more than 150 g. For this project, I used a noble, two-tone card- board from the GMUND 925 series) • Damp cloth (optional) Equipment Needed: For the best cutting results, use a hon- eycomb cutting tabletop. The minimum contact area will keep residue on the back of the material to a minimum. Alterna- tively, you can use an aluminum cutting grid table. Step One: Design Create your own design or download a premade template. See Image 1 for the design template or download the PDF: www.bit.ly/CardTemplateTrotec. The colors listed in the engraving parameters below refer to the colors of the specific pieces in the design template. Due to the special characteristics of the paper, you can create two different levels of engraving. Test this using the grayscale matrix. (Image 2) Image 4: For a perfect cutting result, use different laser parameters for the complex geometries of the tree and outer contour of the card. Laser Process Creative Christmas Cards Step Two: Laser Processing Put the paper on the honeycomb cutting tabletop and cover the rest of the table. This ensures full vacuum of the engraving table and prevents the paper from shifting. (Image 3) Using a 120-watt laser with a 1.5-inch lens, send the job to the laser using the following parameters: Engraving 1 (black): Power: 40%; Speed: 70%; 500 ppi; Air-Assist: On Engraving 2 (red): Power: 14%; Speed: 70%; 500 ppi; Air Assist: On Cutting 1 (blue): Power: 5%; Speed: 3%; 1000 ppi; Air Assist: On Cutting 2 (cyan): Power: 5.1%; Speed: 1%; 1000 ppi; Air Assist: On Cutting 3 (green): Power: 15%; Speed: 3%; 1000 ppi; Air Assist: On The laser parameters vary depending on the type of paper you are using. Use the grayscale matrix to find the optimum parameters for your paper. For a perfect cutting result, use different laser parameters for the complex geometries of the tree and outer contour of the card. (Image 4) Step Three: Post-Processing The crease line allows you to easily fold the card. Some types of paper tend to pro- duce traces of smoke. In most cases, they can be removed with a damp cloth.
