2 0 1 5 J U N E P R I N T W E A R || 61 WHAT IS A LASER BRIDGE EMBROIDERY MACHINE? E tching requires a galvanometric laser. This is the type also used for laser bridge machines. Standalone lasers also may also be available as galvanometric or plotter. If you want to etch, make sure the standalone is galvanometric. The laser travels along this bridge and is pro- grammed to stop at each head and cut or etch the item. There's no limit to how long a bridge is built. It's also possible to group several multi- head machines under a single bridge. If you have 36 embroidery heads, a bridge could span over two 18-head machines, three 12-head machines, or six six-head machines. Opposite: Denim is ideal for laser etching because the process removes color from the indigo dyes. It's used to create the worn, distressed look as well as for adding logos or graph- ic elements on a back pocket or down both legs. This page: A laser bridge machine works on cap ap- pliqué. The design on this cap was etched, the shape was cut out, and then sewn using a scalloped stitch. The appliqué fabric was suede, which etches nicely. (Images courtesy BITO and Henry Bernstein)
