Laser engraving on Gravoply has revolutionized the way Australian businesses create professional signage, custom labels, and durable plaques. This premium double-layer engraving material, also known as Traffolyte, delivers stunning contrast and precision that traditional engraving methods simply cannot match. Whether you’re producing industrial labels, decorative signage, or commemorative trophies, mastering the art of Gravoply engraving will elevate your projects to professional standards.
What Makes Gravoply the Ultimate Engraving Material?
Gravoply stands out in the competitive world of engraving materials due to its unique two-layer construction. The material features a colored cap layer bonded to a contrasting core layer. When your laser engraver removes the top surface, it exposes the underlying color, creating crisp, permanent markings that resist fading, weathering, and wear.
This innovative design makes Gravoply particularly valuable for applications requiring durability and readability. From industrial equipment labels that must withstand harsh environments to elegant indoor plaques, Gravoply delivers consistent results that maintain their visual impact for years.
Essential Equipment for Gravoply Engraving
Before diving into techniques, ensure you have the right laser system. CO2 lasers are the gold standard for Gravoply engraving, typically requiring at least 40 watts of power for optimal results. Fiber lasers can also work effectively, though settings will differ significantly.
Critical accessories include proper ventilation or fume extraction systems, as engraving plastic materials releases fumes that require adequate removal. An air assist feature helps prevent melting and burn marks by cooling the material during the engraving process, resulting in cleaner edges and sharper detail.
Step 1: Prepare Your Gravoply Material
Success begins with proper material preparation. Start by removing any protective film from your Gravoply sheet. Clean the surface with a soft cloth and mild detergent to remove dust, fingerprints, or oils that could affect engraving quality.
Secure your material firmly in the laser bed using appropriate fixtures or jigs. Movement during engraving ruins precision, so take time to ensure stability. For irregularly shaped pieces or small items, custom jigs prevent shifting and guarantee consistent results across multiple projects.
Step 2: Configure Your Laser Settings
Laser settings determine the difference between professional results and disappointing failures. For standard Gravoply sheets, start with conservative settings and adjust based on your specific material thickness and desired depth.
Begin with moderate power levels around 10-15% of your laser’s maximum capacity and engraving speeds between 400-600mm/s. These baseline settings work for most applications, but every laser system behaves differently. The goal is to remove the cap layer completely while avoiding excessive melting or discoloration of the core material.
Increase your lines per inch (LPI) setting for smoother results. Higher LPI values mean more laser passes over the same area, creating a more uniform surface finish. Settings between 300-500 LPI typically produce excellent results for detailed work.
Step 3: Master Focus and Depth Control
Precise focus is non-negotiable for quality Gravoply engraving. Your laser’s focal point should sit exactly at the material surface. Most laser systems include focusing tools or gauges; use them every time you set up a new job.
For Gravoply, you’re aiming to engrave through the cap layer without significantly cutting into the core. This typically requires shallow engraving depth. Monitor your first few passes closely and adjust power or speed if you’re not achieving clean color transitions.
Step 4: Optimize Your Design Files
File preparation significantly impacts final results. Convert your designs to vector format when possible, as vectors produce cleaner lines than raster images. Use black fills for areas to engrave and set stroke lines appropriately for your design needs.
Avoid unnecessary duplicate lines in your design files, as these waste time and can cause over-engraving. Clean up your artwork before importing it to your laser software, eliminating any overlapping paths or redundant elements.
For text-heavy projects, select fonts with good readability at your intended size. Extremely thin or ornate fonts may not reproduce well at small scales, so test different options on scrap material first.
Step 5: Test, Adjust, and Perfect
Professional engravers never skip test runs. Cut small samples with different settings to find your optimal parameters. Create a test matrix varying power, speed, and LPI to see how each affects your specific Gravoply material.
Document your successful settings for future reference. Different Gravoply color combinations may require slight adjustments, so maintain a settings library for each variation you commonly use.
Pay attention to edge quality. If you see excessive melting or rough edges, reduce power or increase speed. If the cap layer isn’t fully removed, increase power slightly or decrease speed until you achieve complete color transition.
Step 6: Post-Engraving Finishing
After engraving, some Gravoply pieces benefit from gentle cleaning. Use a soft brush or compressed air to remove any debris from engraved areas. For deeper engravings, you can enhance contrast by filling engraved sections with paint or ink, then wiping away excess from the surface.
Allow painted pieces to dry completely before handling. This technique works beautifully for outdoor signage or applications requiring maximum visibility.
Step 7: Troubleshooting Common Issues
Encountering problems is part of the learning process. If you notice graying or discoloration in your engraved areas, you’re likely using too much power or moving too slowly, causing excessive heat buildup. Reduce power incrementally and increase speed until the issue resolves.
Incomplete cap removal indicates insufficient power or excessive speed. Make small adjustments rather than dramatic changes to find the sweet spot. Remember that material thickness variations can affect results, so verify your Gravoply specifications.
