Reduce Coverage: This option is mainly used with the 8845 printer. 
This is the same as selecting the U macro.
Raster Rendering: Options selected here can also be selected from the 
Raster Imaging tabbed dialog box of the Printer Interface. For more 
information see page 8-35 of this user guide. The following options are 
available here:
Printer Default: Uses the rendering method selected in the Printer 
Interface.
Diffused: When Diffused is selected, dots are placed to approximate 
source pixels . The amount of "error" in the approximation is balanced 
with adjoining source pixels to better approximate the source image. 
This option is ideal when printing a continuous gradient from black to 
white or printing line drawings.
This type of dithering is applied when the Repro Desk option “Use Error 
Diffusion for Gray or Color RTL images” check box is selected.
This option provides the same functionality as specifying the R macro.
Ordered: When Ordered is selected, dots are placed in a regular pattern 
to approximate the source pixel. A lighter source pixel is mapped to a 
pattern containing fewer pixels, while a dense pattern is applied for dark 
pixels. This is the default option for color and RTL printers. Ordered 
Dither is also automatically applied when a Repro Desk job is imported 
into PlotWorks and the “Use Error Diffusion for Gray or Color RTL 
images” check box is not selected in Repro Desk. This option is ideal:
When printing in color
When printing drawings that contain fills
When printing photos.
For printing output similar to Repro Desk raster output when the 
Repro Desk option “Use Error Diffusion for Gray or Color RTL 
images” check box is not selected. In this case select Ordered Dither 
from the Raster Imaging tabbed dialog box. 
When printing using the Océ 9800 series of printers.
When you want print output to resemble output from the Océ 9800 
printers
This option provides the same functionality as specifying the 
macro
.
Ordered Pattern Set: Options are:
