1-Touch Laser Photo Switch
This switch is automatically selected when printing photos from Universal Laser Systems 1-touch
Photo laser photo printing software. This switch also be selected when printing a photo processed by
1-Touch Photo and then imported into other software before printing. This switch optimizes settings
for best results with 1-Touch Photo images.
Image Density
The Image Density setting determines how many lines of pixels (or dots) per vertical inch are used to
render a raster image on the material being laser marked or engraved. It can also be referred to as the
vertical resolution or dpi of the image. There are seven image density choices available in most models
(two extra density levels are available in SuperSpeed models). Higher Image Density (DPI) settings
produce better quality raster images with finer detail, but reduce productivity by increasing raster
engraving time. Lower Image Density (DPI) settings produce lower quality raster images, but increase
productivity by decreasing raster engraving time.
Image Density (DPI) settings will also have an effect on vector quality and processing speeds when
vectors objects contain many curves and small segments. Higher image densities will produce finer vector
detail, but may reduce productivity and vice versa for lower image densities. By running samples on scrap
materials and tying different density settings, you can find a compromise between throughput and image
quality that is acceptable to you.
SuperSpeed (optional accessory)
If the optional SuperSpeed accessory is installed a switch will be present to turn activate the feature. This
feature uses a beam splitter to separate the laser beams from the top and bottom lasers by a controlled
amount so that they will focus, one above the other on the material processing table with a distance
between them equal to the density selected. Each laser is pulsed separately, to allow two lines of raster
data to be engraved simultaneously which will cut job completion time in half. When this switch is
activated two extra densities become available. See the accessories section for more details on operation
of the SuperSpeed.
Print Direction
The default direction is Down which begins raster engraving at the top of the field and finishes at the
bottom. On some materials you may get better results by starting at the bottom and engraving towards
the top of the field (Up) due to the fact that smoke and fumes from the engraving process travel over the
surface of the material before being exhausted and can mar the previously engraved areas.
