A. Choose Printing Mode
A-1 B/W (Black & White) Mode–
It is useful to activate this mode when using ClipArt or drawings with
several colors, shades of gray, or many outlines. This mode will create a laser output similar to that of
a laser printer. The entire selected image will be engraved using a single pen, black one (power &
speed setting). The ZX SERIES driver will interpret colored and shaded areas as different shades of
gray by producing a halftone effect while engraving. Instead of engraving only solid lines,
gray/halftone areas will be a collection of dots. The resolution and depth of these halftone areas can
be adjusted with the DPI, the B/W mode dithering settings from 2x2 to 8x8, error diffusion, and pattern
type. Experiment with these different settings to get the best results.
Fig. 6-10 Raster Dithering mode setting
Dithering type – The gray areas of image will be filled with from a 5- grade halftone with 2x2
dots to a 65- grade halftone with 8x8 dots. 8x8 dithering type would presents the image into
different shading effect than the 2x2 dithering, while the 2x2 dithering type would have smaller
dots than 8x8, that produces higher resolution. The dithering type choice would depend on the
image and application.
Enhance dithering – The enhance dithering as what it reads would help to compensate the
shortage of smaller grade halftone type, such as choosing 2x2 dithering type and enhance
dithering at the same time, the image would be printed with 256- grade halftone and 2x2 dots,
therefore, better shading effect with small 2x2 dots/ grids.
Error Diffusion – The error diffusion presents the shade of image as a spread halftone instead
of dots, therefore more detailed.
