Acrylic:
There are two different types of acrylic
– cast and extruded. The cast acrylic becomes white
or mat after engraving, the extruded acrylic remains clear. Use extruded acrylic for
engravings that are filled with paint and cast acrylic for normal engravings. Cast acrylic can
be best engraved without protection foil. It is better to engrave the entire surface with a low
energy setting.
Engraving photographs:
Engraving photographs can be quite a challenge at the beginning. But as soon as you
understand the basics it will become easier for you. Scan the desired picture with a
resolution of 300 dpi. Adjust brightness and contrast so that lighter colors become lighter
and darker colors become darker. The photo might look better if you use a filter, which
sharpens the contours. The next step is the selection of a raster. Usually the software offers
a selection of different rasters with a specified number of lines per inch and different raster
angles. Use a raster with between 20 and 100 lines per inch. Increasing the number of lines
per inch decreases the size of the points. Try which raster you think looks best. With one
material large dot look better, with another material smaller points look better. If you cannot
select rasters with your software, the machine will select the raster automatically.
