DPI (Options Page) [DEFAULT SETTING: 500]
DPI (dots-per-inch) represents the number of times the laser will fire over a one-inch path. This setting
determines the image resolution and quality when performing raster engraving functions. Higher DPI
settings result in cleaner and deeper engravings but require more time to complete. Lower DPI settings result
in coarser and shallower engravings but require less time to complete. The LV-290 offers 8 DPI options: 125,
250, 300, 380, 500, 600, 760, 1000, and 1500 experiment with different settings to get your desired effect.
Below is a chart for your convenience detailing the Set DPI (your input setting) vs. Actual DPI (your output results).
Set DPI 125 250 300* 380 500 600* 760 1000 1500
Actual DPI 127 254 381 381 508 762 762 1016 1524
NOTE
Outputting a full-table (25.1" x 18.1") job using 300 or 600 DPI will result in a truncation error; this is
due to the large differences in set DPI vs. actual DPI output for those two particular DPI settings.
Therefore, when processing a 25.1" x 18.1" job using 300 DPI, we recommend you move to the next
higher DPI setting of 380. Similarly, for a 25.1" x 18.1" job using 600 DPI, we recommend you use
760 DPI.
Mirror (Options Page) [DEFAULT SETTING: Unselected]
Checking this box will automatically engrave your image with a mirrored effect. This setting will flip the image
along the Y-axis from left to right and vice-versa.
Tip
When engraving a stamp, via the stamp mode, the stamp image needs to be engraved in reverse
(mirrored) for the final stamp to be correctly laid out.
