Laser engraving - Dark natural textiles
Dark materials including denim or cotton fabrics can be easily “bleached” using laser engraving. For this process a low laser power (up to approx. 20% at 100 watts) must be used and the engraving should be done without Z offset, (material dependant).
CAUTION: Using too much laser power or resolution which is too high can tear the fabric or dissolve the fibers, immediately or after the first wash at the latest. Depending on the graphic, a resolution of 250 to 500dpi is suitable.
Laser engraving - Light natural textiles
In order to achieve a dark laser engraving results on light textiles, deliberate defocusing is required, for example a Z offset of approx. 2 to 20 mm is used depending on the material. The further the lens is from the material, the larger the laser spot.
Laser cutting - Natural textiles
Use a frequency of 1000 to 3000 Hz for laser cutting. To avoid dark edges, we recommend switching on Air Assist during the cutting process and using the nozzle with the smallest diameter.
