Default = 3
Range = 0 to 19 (invalid values are ignored; values 1, 2, 9, and 10 are ignored for device independent color)
Snap to Primaries
This algorithm converts each component of a color specification to its corresponding primary color. For example, assuming 8 bits per primary, an RGB input value greater than 128 snaps to 255; a value less than or equal to 128 snaps to 0.
Snap Black to White, Colors to Black
Choosing this option converts black to white and all other colors to black. Input primary colors equal to a black specification are converted to a white specification, and other color specifications for the input primaries are converted to the black specification.
Device Best Dither
This dither pattern produces the best results for many images. Note, however, that the recommended dither pattern varies with the image, the intended use of the image, and the subjective judgements of the user.
Error Diffusion
The input primaries of a given pixel (x,y) are printed at the closest density available and the local error is propagated to the unprinted neighboring pixels. Error diffusion applies only to raster data printed using the Configure Image Data command.
