O. C. [. . . ] The Grayscale 16-bit option is provided in ScanWizard Pro for professional pre-press scanners. CMYK CMYK images are made up of the standard four colors (cyan, magenta, yellow and black or K) for separated film or digital files used for sheetfed or web offset printing. CMYK mode instantly converts the scanner's RGB input to the CMYK color space. CMYK images are four-channel images, containing 32 bits per pixel. Lab Color Lab images are three-channel images containing 24 bits per pixel. Lab mode is useful for editing a pixel's luminance but not its color values. Lab mode produces device-independent color and is recommended for moving images between systems or printing to a PostScript Level 2 printer. 60 Microtek ScanWizard Pro for Macintosh Web / Internet Colors This mode is useful for displaying images on the Web or Internet. Output for the Web / Internet color mode in ScanWizard Pro is 8-bit, 256 indexed color images in the sRGB color space. 256 Colors (Default) / 256 Colors (Custom) These are single-channel images (8 bits per pixel) that use a color lookup table containing up to 256 colors. The file size is smaller for images in this mode. As an initial setting, selecting 256 Colors (Default) uses an Adaptive palette with Diffusion. If the 256 Colors (Custom) option is selected, the dialog box below appears. 1) Palette: The Palette option lets you choose the method for creating the color palette table. Uniform uses a 6-66 fixed color palette table. Adaptive (default) creates a color palette table from the more commonly used areas of the color spectrum that appears in the image. 2) Dither: The Dither option can improve the color quality of the 256-indexed color image for photographs or continuous-tone images, using a technique of mixing available colors to simulate missing colors. Pattern uses a structured pattern to simulate missing colors. Diffusion (default) uses the error diffusion technique to dither colors and produces the best quality for 256 colors. Line art Line Art images are made up of one bit of color (black or white) per pixel. Few editing options are available in this mode, but this mode is useful for images consisting purely of black and white or even single colors, such as mechanical drawings, blueprints, or fine-line illustrations. Black-and-White Diffusion This is a single-bit black-and-white image dithered with error diffusion. The black and white pixels are arranged in a way as to "fool" the eye into seeing gray. Reference: The Settings Window 61 Resolution settings The settings related to resolution include the resolution box, the resolution list box, and the resolution unit. [. . . ] The theory is simple: Whenever amounts of cyan, magenta, and yellow are present in the same color, that color has a gray component. Some or all of this gray component can be printed with black ink while maintaining the original color appearances. In contrast to UCR, GCR involves a more general color replacement, with black being substituted over all colors. The neutral center of both diagrams looks the same. [. . . ]
