[. . . ] 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 6-6-6 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. 56 Microtek ScanWizard Pro TX for Mac & PC Resolution settings The settings related to resolution include the resolution box, the resolution list box, and the resolution unit. Resolution is the sampling of image pixels per measurement unit or the amount of pixel information stored in an image. Together, the image resolution and dimensions determine the file size of the image, which is measured in kilobytes (KB) or megabytes (MB). The resolution of an image is important in determining the quality of the output image. Resolution is also directly related to file size, and the higher the resolution, the larger the resulting file size will be. When dealing with resolution, remember to distinguish between optical resolution and interpolated resolution. Optical resolution is the "real" resolution as measured by the scanner's optics. Interpolated resolution is software-enhanced resolution and can be useful for enlarging very small images or for printing line art to obtain superior results. A. Resolution list box This shows the resolution setting. [. . . ] Kodak's ICC profiles ) may contain some proprietary profile information that could benefit the original CMM to reproduce more accurate color. Therefore, it is highly recommend to duplicate a copy of the profile in C:\Windows\System\Color folder that you're going to use for calibrating your monitor. In the following example, select "Copy of P22G18M7. ICM*" -- a duplicate of P22G18M7. ICM" which represents "Generic P22 1. 8 Gamma" monitor. *The file "Copy of P22G18M7. ICM" is generated by selecting P22G18M7. ICM from this dialog box first. Press Ctrl+C to copy, then press Ctrl+V to paste. 138 ScanWizard Pro TX for Mac & PC 4.
