Automatic Enhancements with Margins (Drop Down Menu)
Calculates optimal enhancements but with margins on either side of the printing for best edge
quality. With margins added the motion system over-strokes (travels beyond the edge of the
print data) so that the motion system does not try to laser mark or engrave while it is
accelerating or decelerating to change direction for the next raster stroke. If engraving or
marking near the edges of the laser processing field these margins are automatically reduced.
Automatic Enhancements without Margins (Drop Down Menu)
Decreases file completion times by removing over stroke margins. The laser system attempts to
compensate for laser response while accelerating or decelerating to change directions for the
next raster stroke, but edge quality may suffer on some materials.
Image Enhancement Manual Mode
In manual mode, Image Enhancement controls (CONTRAST, DEFINITION and DENSITY) can be adjusted
manually. Keep in mind that the TUNING value may need to be readjusted for different settings of the
manual image enhancements. Manual mode settings are explained here:
Contrast
CONTRAST increases laser power at the edges of thin graphical elements in areas of a graphic that
are high density (a lot of detail packed close together) such as the area outlined in the figure below:
Within this area, using too little CONTRAST may cause thinner parts of the letters or thin vertical
lines to appear too thin, faint or even non-existent when rastering at high speeds. Having too much
CONTRAST will cause the affected areas to appear too thick, bold or over-powered.
Definition
DEFINITION increases laser power at the edges of thin graphical elements in areas of a graphic that
are lower density (graphic elements with a lot of white space around them) such as the area
outlined in the figure below:
The low-density parts of the graphic are typically the ascenders and descenders of text or thin
vertical lines in a graphic being printed. Within this area, using too little DEFINITION may cause
thinner parts of the letters or thin vertical lines to appear too thin, faint or even non-existent when
rastering at high speeds. Having too much DEFINITION will cause the affected areas to appear too
thick, bold or over-powered.
Density
DENSITY decreases laser power at the edges of all graphical elements to compensate for laser lag in
turning off at high speeds. If the DENSITY is set too high, then the entire engraved image may
appear too thick, bold or over-powered. Setting the DENSITY too low may cause the image to appear
