ADDITIONAL COMMENTS
Engraving photographs can be challenging at first but becomes easier once there is an understanding of
what to look for and how to achieve the desired results. In an image processing software, scan the
image in at 300 DPI. Adjust the brightness and the contrast to brighten the light colors and darken the
dark colors. The photo might look better by using a sharpening filter to sharpen up the image slightly.
The next step is to select a halftone pattern. Usually, imaging software gives the choice of using
different halftone patterns including frequency of lines per inch and pattern angles. Use a line frequency
above 20 and below 100. The size of the dots decreases as the line frequency increases. Experiment
to see which pattern looks the best. Big dots look good on some materials and small dots look better
on others. If it is not possible to assign a halftone pattern in the imaging software, the ULS Windows
printer driver will automatically default to a predetermined pattern based on
FILL SPACING
. The
driver will automatically assign a 90 lines per inch, diamond shape halftone pattern at an angle of 45
degrees when the
FILL
SPACING
is set to
2
and the
HIGH RESOLUTION
switch is
ON
. It will
assign a 45 line per inch diamond shape halftone pattern at an angle of 45 degrees when the
FILL
SPACING
is set to
4
and the
HIGH RESOLUTION
switch is turned
OFF
. Choosing a fill spacing
larger than
4
is not recommended because resolution becomes too coarse. When using the
B/W
RASTER
mode switch, which prints all ClipArt or drawings as grayscale bitmaps, use the same
parameters and techniques as for engraving photographs.
