Section 7: Using the Epilog Dashboard

Resolution
Print quality is commonly referred to as Resolution, and is one of the variables
that determine image quality when engraving in raster mode. Resolution is
expressed in dots-per-inch (DPI) and is determined by the number of lines or dots
that are engraved for every inch of movement. Each horizontal line is referred to
as a raster line. The higher the resolution setting, the finer the detail that can be
achieved. This Epilog laser system can engrave at resolutions ranging from 100
to 1000 DPI. Keep in mind that engraving resolution is only one factor in
determining image quality. The quality of the artwork being sent to the laser can
have a bigger influence on the look of the final product than the resolution. If low
quality artwork is sent to the laser system, even the highest resolution will not
improve it. Also keep in mind that image quality is subjective. 300 DPI may be
just fine for some images and some customers, while 500 DPI is the absolute
minimum for others.
Speed and Power settings are dependent on resolution setting. For example, there
is greater overlap of each raster line at 500 DPI than there is at 300 DPI. The
additional overlap at 500 DPI has the effect of lasering over more of each line
twice. This means that on material like wood, you will notice a greater depth of
engraving at 500 DPI than you will at 300 DPI if you use the same Speed and
Power settings.
Resolution (Print
Quality) is set in
the Dashboard prior
to sending the job
to the laser.
Higher resolution
produces better
image quality.
