Essential Tips To Consider For Engraving Laminates


Laser machines have come a long way to prove themselves as one of the immeasurably helpful tools for engravers, manufacturing companies, and retailers. Although there is a spectrum of materials that can be engraved with the help of a laser, there are some considerations and adjustments you would have to make while engraving certain surfaces.

Listed below are some of the techniques that would be instrumental in the procedure for engraving laminated surfaces.

Soft Focus

If in case you have the job of conducting a reverse engraving of the given materials, you can consider making a second pass with a soft focus that would facilitate the creation of a supple glass-like finish for the end product. For this, you would have to focus your laser beam on the surface of the material and let the first raster pass. After that, you would have to reduce the laser out of the focal point by 0.5 millimeters to allow to run for the second pass.

Bottom-up Engraving

You can use your laser to start engraving from the bottom of the material instead of the usual orientation. This simple reversal of the procedure would eventually lessen the generation of residue that is produced in the duration of the process over the surface of the already engraved material. This would provide a solution for the issue from the residue being re-deposited on the heated core of the material, thereby making it incredibly difficult to clean afterward.

PPI or, Resolution

If you can reduce the number of pulse firings per inch, especially in case of engraving comparatively larger text or objects, it would help you to retain the cooler temperature of the material on which the engraving is being done. Make sure that you set your PPI at around 500 to facilitate the photoengraving process in order to decrease the so-called branding effect which is a common problem that can be found throughout the process of fabrication.

Color Contrasting

One of the primary problems that one faces while dealing with white core colors and comparatively darker top colors are while achieving distinctively sharp, white engraving onto the surface of the product. Here again, the previously mentioned bottom-up engraving technique would assist you in minimizing the redistribution of the pigmented residue that can form over the white surface. In order to achieve this, you would have to increase the power in 5% increments and conduct multiple processes to finally generate an end product that would be in line with your preferences.

Vector Cutting

If you have the ability to make use of protecting masking in the place where you would be conducting vector cuts, it is recommended that you implement this technique into the procedure. The integration of this technique would assist you to reduce the generated residue, helping you to minimize the efforts that would be required in a cleanup. For this to materialize, you have to ensure that the laser beam of the device is placed in such a manner so as to focus on cleaner and smoother cuts.

Air Assist

This procedure is habitually inculcated in the arena of a vector cutting applications in order to get rid of the heat and the combustible gases that can be emitted from the cutting of the surface. This is done by channelizing a steady stream of air across the surface that is being cut so as to minimize the possibility of potential framing or scorching.
