Choosing the right resolution has a huge impact on the engraving result. The material used, the graphic content and the processing time play an important role.
Materials absorb energy during laser engraving. Due to the strong heating, the dots become larger and can overlap (= “dot bleed”). This property is particularly important for photo engraving and must be considered. In order to counter this effect, the right resolution is crucial.
Used material | Preferred resolutions |
---|---|
wood, glass, textile, stone | lower resolutions: 125, 250 und 333 dpi |
acrylic, TroLase materials, paper, cardboard | moderate resolutions: von 500 bis 600 dpi |
stamps, metal, processing with fiber laser | higher resolutions: von 600 bis 1000 dpi |
Depending on the level of detail in the graphic, it is recommended to increase the resolution to 600 dpi despite the “dot bleed” described above. This allows even very fine details to be optimally engraved.
The higher the selected resolution, the more time is needed for the laser engraving.
If you choose a different resolution, you can also save engraving time. For large-scale engravings, for example, choose a lower resolution and compensate for the resulting line spacing with a higher Z offset value.
See our example of how you can engrave the same graphic at 500dpi with the same result at 125 dpi in just 1/4 of the time:
Speedy 360, 80 Watt, P=65%, v=50% | ||||
---|---|---|---|---|
Resolution | 125 dpi | 250 dpi | 333 dpi | 500 dpi |
z-Offset | +12 mm | +12 mm | +9 mm | +6 mm |
time [h] | 1,52 | 3,31 | 4,28 | 6,47 |
In this case, a higher resolution will increase the energy density when engraving. If the stamp is engraved at 500 dpi, the engraving speed must be reduced in order to reach the recommended engraving depth of 1.1 mm. In contrast, engraving can be faster at a resolution of 1,000 dpi and thus some time can be saved despite the higher resolution.
