Longer Laser Engravers help you create high-quality artwork and personalized items with ease. They are suitable for both beginners and experienced creators who want to explore different engraving projects.
Their excellent engraving and cutting abilities support a wide range of materials. Creators often choose glass and stainless steel for industrial-style projects.
Rainbow Scratch Paper provides a more colorful and creative option for laser engraving. This material helps you create high-contrast and colorful designs. You can use it for custom illustrations, artistic stationery, unique greeting cards, and eye-catching decorations.
Scratch Rainbow Art Paper Laser Engraving: A Step-by-Step Guide
Scratch Rainbow Art Paper is a popular material among artists and hobbyists because of its striking visual effect. It usually features a matte black top layer with a colorful background layer underneath.
Laser Engravers can engrave scratch paper with millimeter-level precision. However, unlike wood and other solid materials, it is much thinner and more delicate. Scratch Rainbow Art Paper uses thin, multi-layer coated paper, so you should handle it carefully during laser processing.
The laser only removes the thin black top coating to reveal the rainbow gradient underneath. Therefore, the laser beam needs to work like a delicate brush. It should selectively remove the dark surface layer without burning through the paper below.
To achieve clear and vivid engraving results, carefully adjust the power and speed parameters. Scratch paper usually requires lower power and faster speeds compared with many other materials.
These settings allow the laser to work on each point for a short time. The laser removes the black matte layer to reveal the rainbow colors underneath. You can create detailed designs, such as fairy illustrations or geometric patterns, while keeping the base layer intact.
You can use air assist during this process for cleaner and more accurate engraving. It helps remove tiny black dust particles created during engraving. This keeps the engraving area cleaner and improves processing accuracy.
Recommended Laser Engraving Settings for Scratch Rainbow Art Paper
Before engraving scratch paper, it is a good practice to secure the edges of the sheet flat on the working bed. You can use honeycomb pins or low-tack tape to prevent the paper from moving or lifting during fast engraving passes.
To engrave a scratch rainbow sheet like the example shown, use the following basic parameters. These settings work well with different Longer models and help reveal vibrant colors without burning the backing layer.
- Longer Nano Pro: Power 12.5% - Speed 6000 (mm/min)
- Longer Nano: Power 20% - Speed 6000 (mm/min)
- Longer B1 40W: Power 12.5% - Speed 8000 (mm/min)
- Longer Ray5 10W: Power 12.5% - Speed 6000 (mm/min)
Note: Low power settings are crucial to prevent burning through the delicate colored layer. You can adjust the settings based on the thickness of the specific paper brand’s top coating.

Tips for Achieving Clean and Vibrant Engravings
With the correct settings, the laser can remove the black coating from the selected areas smoothly. The laser creates gentle heat during engraving. This heat removes the surface layer and reveals the colors underneath without damaging the rainbow background.
The engraving process leaves behind a powder-like coating residue. Clean the paper lightly after processing to remove the residue. A soft, clean, dry brush is a practical solution for removing loose black residue. You can also use a gentle puff of air to clear away any remaining particles.
After cleaning, the paper will show a permanent and vibrant artwork. It can feature a magical fairy on a crescent moon or any detailed design that shines with brilliant rainbow colors.
One of the most interesting features of Scratch Rainbow Art Paper is its naturally high contrast. The dark coating absorbs diode laser light effectively, even at low power settings. This allows you to create extremely sharp details.
Creative Applications of Scratch Rainbow Art Paper
Scratch paper engraving has many practical applications. You can use it to create custom products, including:
- Art prints
- Decorative bookmarks
- Festive invitations
- Promotional displays
- Creative craft kits
Longer Laser Engravers offer millimeter-level precision. They help you create fine linework and detailed silhouettes with consistent results. The laser reveals colorful rainbow effects.
Maintenance and Safety Tips for Laser Engraving Paper
1. Clean the machine after engraving
Removing the black scratch layer creates fine carbon dust. Clean the countertop and laser module regularly with a dry or slightly damp cloth. Also, check the air assist nozzle and laser lens to maintain proper airflow and engraving performance.
2. Test your settings before engraving the final design
Paper is thin and flammable, so always test on a scrap piece or an unused area of the sheet first. Unlike metal or ceramic, paper has less tolerance for incorrect settings. Too much power or a slower speed may cause burn marks or damage the material.
3. Monitor the engraving results during testing
Browned edges or gray areas around the rainbow colors indicate excessive heat. Low power or high speed can achieve better results.
4. Keep the paper flat during processing
Lightweight paper can move under strong airflow. Make sure the sheet stays flat and keep the laser protective enclosure active during engraving.
By following these steps, you can achieve clean and safe results for your paper art projects.
