Halftone (Raster Page) [DEFAULT SETTING: Dithering]
This option controls the way a raster-engraved image is processed. The “digital image to engraved output”
process can be processed via two methods: Dithering or Error Diffusion. Each offer additional output options
yielding different output effects, style, and quality.
•
Dithering
: Interprets and outputs the raster engraving via the dithering method. This mode will allow you to
select the Pattern Type and Dithering Matrix, and Enhanced Dithering.
-
Pattern Type
: Dot, Bayer, Corner, 45 Degree [DEFAULT SETTING: Dot]
Each pattern type uses a different shape and arrangement of dots to compose the shading effect of
a raster image.
The following diagram is an example of the raster effects when using the different pattern types.
-
Dithering Matrix
: Variable depending on the Pattern Type selected. [DEFAULT SETTING: 8x8]
This controls the resolution (dot size) and the number of dots the image is broken down into for the
dithering process. As an example, selecting 2 x 2 will shade with a 5-grade halftone, where as an 8 x
8 Dithering Matrix will dither with a 65-grade halftone.
The following diagram is an example of the raster effects when using the different dithering matrices.
-
Enhance Dithering
[DEFAULT SETTING: Unselected]
Selecting this will produce a finer dithering output.
-
Error Diffusion (Raster Page)
: Interprets and outputs the raster engraving via the error 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.
