Contrast (Raster Page) [DEFAULT SETTING: 0]
This provides a quick and easy way to immediately adjust the contrast of an engraved image. Moving the
slider to the Dark setting will increase the contrast levels of the engraved output, whereas moving the slider
to the Light setting will decrease the contrast levels of the engraved output.
TIP
There are other ways to adjust an engraved image's contrast such as: adjust the power/ speed
settings or simply adjust the contrast of the image in software with the graphic software application.
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.
o 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.
Dot
o Dithering Matrix [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.
