A lot of people have problems with plastics that either have a red or blue top on white or vice versa a white top and either a red or white core. The problem that people have is typically a contamination of the color that invades the white and discolor the white core. In some of the earlier days of laser engraving I use to have a lot of problems with the Rowmark Lasermark series. However this problem for me has become a non issue since the release of our new Trolase laserable product. This product has a very good acrylic core and the pigments from the colors do not migrate like they do on other plastics. However, there is one thing as a laser engraver that you have to do and that is using the least amount of power that you can. This is not only in raster engraving, but also in vector engraving. The problem that people have is that they use way too much power. In this video I am going at 100% speed, 19% power and 600 DPI on a 60 watt laser. DO NOT USE WHAT YOUR LASER SUPPLIER SAYS – TEST YOUR MATERIALS WITH YOUR LASER.
