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 Printer Driver will
automatically default to a predetermined pattern based on
RESOLUTION . Refer to the
chart below.
RESOLUTION ANGLE SHAPE LINES PER INCH
1000 45 DEGREES ROUND 180
500 45 DEGREES ROUND 90
333 45 DEGREES ROUND 60
250 45 DEGREES ROUND 45
200 45 DEGREES ROUND 36
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.
