Error Diffusion (Raster Page):

diffusion method. This mode will allow you to select from three diffusion types: Floyd, Stucki, and
Jarvis.

Diffusion Type: Floyd, Stucki, Jarvis
[DEFAULT SETTING: Floyd]
Each diffusion type presents the shade of image as different spread halftones instead of
dots to compose a raster image.
The following diagram is an example of the raster effects when using the different
diffusion types.

TIP
There is no “correct” or “best” setting when using the Raster options. The most
appropriate settings will be based on a variety of factors: your design, the material you
are engraving on, the results you wish to achieve, etc. Please take some time to
experiment with the multitude of raster options to get the one you feel is the best for
your piece. This is where much of the fun in engraving is….experimentation!
