See § Setting Engraving Parameters
Setting Engraving Parameters
Customize your contrast and engraving depth by adjusting the
engraving parameters in EZCad.
• To darken an image, use a higher frequency setting. To
lighten it, use a lower one.
• To increase engraving depth, increase the amount of energy
per unit area by reducing the speed parameter or increasing
the laser's power or the number of loops.
Engraving too deep, however, reduces image quality, especially for coated
materials.
Constantly using settings over 80% will shorten the expected service life
of your laser.
Resolution should usually be set to 500 dots per inch. Reducing your
image resolution can be helpful in some cases, reducing flaming and
increasing the energy of the pulse in a way that improves the quality of
the resultant image in some materials such as some plastics.
