Fabrics That K15Pro Prints
The K15 Pro’s high-precision blue diode laser can mark or slightly burn the surface of many natural and blended fabrics. Unlike printing with ink, laser engraving uses heat to create a permanent, textured mark.The results vary depending on the fabric’s material, color, and thickness.

FAQ
Engraving on fabric with the Carverall K15 Pro is a creative way to personalize clothing, tote bags, and accessories. With proper material selection and laser settings, you can achieve clean, stylish, and long-lasting designs that give your DIY projects a professional finish.
Q1: Can I engrave colorful images?
No — The patterns is achieved by laser etching the surface of the materials, laser engraving burns the fabric, producing a monochrome mark only.
Q2: How do I stop the fabric from burning?
Please always test the materials before formal print on your fabrics, lower the laser power, increase speed slightly, and keep the laser in focus.
Q3: Can suede be laser-engraved safely?
Yes, for the Tshirt, the most recommended materials is the Suede Tshirt, but also use low power (around 15–20%) and good ventilation. The result is a soft, velvety texture rather than deep cuts.
Q4: Any Suggestion if I want to print with the laser machine?
- Choose bold fonts and simple graphics — fine details can disappear on fabric.
- For maximum contrast, engrave on light-colored fabrics.
- Fix your T-shirt flat on a board or use masking tape to prevent shifting.
- If you’re engraving suede or leather, ventilation is important — mild smoke is normal.
