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 manual. 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 too thin and thinner parts of characters and thin lines
may disappear altogether. The opposite effect would occur on inverted images such as
white text on a black background.
