4. 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.
• For recommended settings for specic materials, see Instructions for Specic Materials (Page 17).
Note:
• 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 aming 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.
