Laser Engraving - Dark Natural Textiles
Dark denim and cotton fabrics can easily be 'bleached' by the laser beam. To do this, it is important to use a lower laser power (approx. 20% at 100w) and to engrave without a Z-offset.
- CAUTION: If you use too much laser power or the resolution is too high, you may rip or damage the fibres of the fabric. Depending on your graphic, a resolution of 250 - 500dpi is suitable.
Laser Engraving - Light Natural Textiles
If you'd like to achieve a dark engraving on a lighter material, you'll need to deliberately defocus the lens. For example, a Z-offset of 2 - 20mm can be used, depending on the material. The further the lens is from the material, the larger the laser spot will grow.
Laser Cutting - Natural Textiles
Try using a frequency of 1000 - 3000Hz when laser cutting. If you want to avoid the rustic, dark edges, try turning on Air Assist during the cutting process and use the nozzle with the smallest diameter. This way, you should achieve the cleanest cut possible.
