+== 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.
