Factors to Consider When Choosing Leather For Laser Engraving:
1. Type of Leather:
The type of leather significantly impacts the engraving outcome. Two common types are:
- Vegetable-Tanned Leather: Known for its natural appearance, it engraves well and develops a charming patina over time.
- Chrome-Tanned Leather: Softer and more pliable, it can be engraved, but the results may be subtler compared to vegetable-tanned leather. However, it’s a good idea to enquire with your leather supplier about the amount of hexavalent chromium (if any) in the leather patches that are chrome-tanned that they offer. However, keep in mind that any leather that has an appropriate exhaust system is safe to use with a laser.
2. Thickness:
Leather comes in various thicknesses, measured in ounces (oz). Consider:
- Thin Leather (2-4 oz): Suitable for detailed engravings, often used in projects like wallets.
- Medium to Thick Leather (5-8 oz): Ideal for items like belts, allowing for deeper and more substantial engravings.
3. Texture:
The texture of the leather affects the engraving’s final appearance:
- Smooth Leather: Offers a consistent surface for detailed engravings, perfect for intricate designs and text.
- Textured or Distressed Leather: Adds character but may result in a more rustic appearance after engraving.
4. Surface Finish:
Consider the finish applied to the leather:
- Aniline-Finished Leather: Known for a natural look and feel, it may engrave well, but the finish can impact engraving contrast.
- Pigmented Leather: Requires higher laser power due to its protective topcoat.
5. Color and Dye:
The color of the leather influences engraving visibility:
- Natural or Light-Colored Leather: Shows details prominently, providing a high-contrast look.
- Dark-Colored Leather: Engravings may be subtle, requiring careful design considerations and laser settings.
6. Quality of Leather:
Opt for high-quality, full-grain leather for better engraving results. Full-grain leather tends to engrave more consistently and beautifully than lower-quality or corrected-grain leather.
7. Testing and Experimentation:
Before starting a significant project, conduct test engravings on small leather scraps. This allows you to fine-tune laser settings and ensure optimal results on your chosen leather type.
8. Masking:
Laser engraving on leather is a delicate process that requires precision and attention to detail. One crucial step to ensure clean and professional results is masking the leather before engraving. Masking protects the surface from smoke, residue, and potential damage during the engraving process. Below we’ll explore how to effectively mask leather for laser engraving and recommend suitable masking tape for the job.
Materials Needed:
- Leather Piece: Choose the type and color of leather suitable for your engraving project.
- Masking Tape: Select a high-quality masking tape suitable for laser engraving.
Steps to Mask Leather for Laser Engraving:
- Step 1: Select the Right Masking Tape:
Choosing the correct masking tape is crucial. Opt for a low-residue and heat-resistant tape designed for laser engraving applications. Blue painter’s tape and certain specialty masking tapes don’t work well for this purpose. We have tested hundreds of masking tapes over the years and have found this semi-transparent masking tape available on Amazon (Paid Link) to be the best.
- Step 2: Cut the Masking Tape:
Cut the masking tape into strips or pieces that align with the dimensions of your leather piece. Ensure that the tape covers the entire engraving area and extends slightly beyond the edges.
- Step 3: Prepare the Leather Surface:
Clean the leather surface thoroughly to remove any dirt, dust, or oils. A clean surface ensures better adhesion of the masking tape.

Press down firmly on the masking tape to ensure good adhesion to the leather. This step is crucial for preventing the laser from seeping underneath the tape during engraving.
- Step 6: Trim Excess Tape:
Using a craft knife or scissors, trim any excess tape extending beyond the edges of the leather. This creates clean edges for a professional finish.
- Step 7: Check for Secure Adhesion:
Double-check that the masking tape is securely adhered to the leather surface. Any loose edges or bubbles may compromise the engraving quality.
- Step 8: Proceed with Laser Engraving:
With the leather properly masked, proceed to set up your laser engraving machine. Ensure that the laser settings are suitable for the type of leather you’re working with.
- Step 9: Post-Engraving Care:
Once the engraving is complete, carefully remove the masking tape. Take your time to avoid any potential damage to the engraved area.
Tips for Successful Masking:
- Use Low-Residue Tape: Choose masking tape with minimal adhesive residue to simplify the post-engraving cleanup process.
- Avoid High-Adhesive Tapes: Steer clear of tapes with excessive adhesion, as they may damage the leather surface upon removal.
- Test on Scrap Pieces: Before masking your main project, conduct tests on small leather scraps to ensure compatibility with your chosen tape.
By following these steps and selecting the right masking tape, you can achieve clean and precise laser engravings on leather, enhancing the overall quality of your projects.
