Error Diffusion

Unlike halftoning, error diffusion scatters the black pixels in a random pattern to represent shading. It

uses the quantity of black dots instead of the size of the black dots to represent the different shades

of gray. The pattern created will be dependent on the quality setting that you choose in the driver

with the exception that there is no chart to reference. Higher quality settings such as 5 will produce a

more densely packed, higher dot quantity pattern whereas lower resolution setting such as 2 will

produce a loosely packed, lower quantity dot pattern

NOTE: DO NOT use Error Diffusion when engraving rubber stamps otherwise dots will appear in the

background. Choose only Halftone.

Black and White Mode

This mode thresholds the image at 50% black. Each pixel that is greater than 50% black will be

converted into white and each pixel that is 50% black or less will be converted into black. This effect

is very similar to trying to duplicate a photograph using a photocopier.

Helpful Tip

Engraving grayscale bitmaps using a dithering pattern requires some practice and a bit of trial and error

to achieve perfection. It also requires some knowledge of bitmap editing software. These images will

visually appear different on one material as opposed to another material even if you use the same driver

settings. As a rule of thumb, use an Image Density setting of 5 using halftone or diffusion pattern on

harder materials such as marble, anodized aluminum or microsurfaced engraver's plastic. Use an Image

Density setting of 3 using the halftone or diffusion pattern for softer materials such as wood or materials

that you intend on engraving very deeply.

Vector Optimizer

The four available selections apply to vector output only and have no effect on raster images. Regardless

of which of the following selections you choose, vectors are grouped by pen color and will always output

in the color order listed in the printer driver.

OFF

Turns off this feature.

ENHANCE ONLY

The printer driver collects all the vectors from the application software and reconstructs them (so

to speak) by removing start and stop points within the vector curves so that they run smoother

with less jitter. It has no effect on straight, horizontal or vertical, lines
