Multiple Waveforms of GCC LaserPro S290LS
GCC, a global forefront equipment-manufacturing provider in the visual communication industry, is pleased to announce that the GCC LaserPro S290LS laser engraver contains unique laser tubes with multiple waveforms.
A waveform is a pulse with a specific shape, pulse energy and duration. The benefits of a waveform are that it allows customers to adjust pulse conditions to optimize marking, micromachining and applications. Users enjoy flexible control over pulse duration and peak power through the use of predefined waveforms. Each waveform is optimized for pulse energy and peak power at a given pulse duration and frequency. These waveforms work for any power demands and frequencies giving users a great scope of pulse characteristic optimization for specific applications.
Below is a table of the corresponding waveforms for different S290LS wattages:
One of the benefits of waveforms is that color marking can be achieved on metal materials. In the picture below, the S290LS 40HHS model is utilized to process matt 304 stainless steel.
The first step of this process is to design a matrix with fixed speed/power range and frequency, then set multiple waveforms as the key parameter; different colors will be marked by laser once this is done.

Here is the suggested parameter setting for the 40HHS model:

  • Low speed range: below 15%
  • Moderate power range: 28~55%
  • Fixed 3000 DPI with waveforms selection 0, 1, 2, 3, 4, 5
Next you will have to select the preferred color, and repeat the corresponding parameters to color your graphic design. This process will greatly save your time compared to traditional complicated parameter experiment steps.


  1. Placing the media over the entire work table may lead to varied color contrast caused by minor changes of spot sizes (power density) on different parts of the work table. Placing the media in the same position will help with color reproduction.
  2. High frequency setting will darken markings and reduce color variation effects; while low frequent setting will only destroy metal surfaces. 125kHz is recommended for frequency setting.
  3. Low DPI setting (below 1500 DPI) will mark materials with different gray levels instead of producing colorful contrast and therefore high DPI is advised.


  1. Color marking is very sensitive to material surface treatments and texture (matt, glossy, brushed, or mirror), spot size (power density), as well as material composition. Even the same parameters applied to the same materials cannot guarantee the exact color duplication.
  2. Marking colors may vary when viewed from different angles with reflected ambient light.
