Xerox 490/980 Color Continuous Feed Printing System

Relative (Default of CMYK)

After dynamic range compression is done, colors that can not be reproduced will be converted, lightness will be sustained as much as possible, and saturation will be decreased. This is not intended for conversion of wide dynamic-ranged images, or high key and low key images.

Saturation

The saturation option is specific for pixels in images. When saturation is changed, it changes the hue and lightness of an image.

It is not recommended to change this option for photos, but is useful for conversion of graphics and charts for presentations.

Absolute

The Absolute option allows colors of reproducible areas to be converted correctly. When colors are converted, lightness is similar to original and saturation will be decreased. For colors in areas that are not reproduced, halftones will decrease significantly. It is not recommended to choose this option for conversion of wide dynamic-ranged images, or high key and low key images.

Output Screen Characteristics

The following options can be selected on the Output screen:

•Screen Job: Selects Halftone Dot [Not Selectable]

•Halftone Dot Shape: Circle [Not Selectable]

•Select Frequency: Choose from 80/100/120/150/200/300

Note

PS/PDF must be the same setting in upstream/downstream. It is only selectable on the upstream system.

Screen Angle: Select C:15 o M:75o Y:0o K:45o [Not Selectable]

User TRC

When the Browse button of User TRC is selected, the Edit TRC window is displayed. Make any desired changes on the Edit TRC window.
