== Grayscale picture printing ==
If you want to print a picture in grayscale, do not activate color mapping. That way, the laser will adjust the laser power:
- Black is the raster power you did set
- White is 0%
- Anything in between will be a percentage of your raster power
== Using the Color mapping ==
In some cases, it is useful to raster or vector with different speeds and powers. To do that use the Color Mapping window in the Driver settings.
To make it easy, start with the basic colors Red (#FF0000 or 255,0,0), Green (#00FF00 or 0,255,0), Blue (#0000FF or 0,0,255). The colors black and white are reserved, white uses no power and black is the power you did set in the first tab.
You can have different settings for raster and vector, but be careful, the number of colors mapped is limited (maybe something like 16).
=== Using the color mapping to test a material ===
You can make yourself a setting for the driver and a small pdf file with full and just border squares of different colors. That way, you can have a test of different settings for your new material just in a single run. One trick is to write the settings directly in your PDF, that way, you can keep your piece of material for latter.
