tell me about scanner operating modes

The scanner can work in the following operating modes:

•RGB mode

•graytone mode

•B/W modes

•2D-sharpening, 2D-softening, and 2D-blur

rgb mode

Full 24-bit true color mode for 16.8 million colors. Use the true color mode for precise reproduction of all color shades. This mode creates large files, especially when scanning large formats.

graytone mode

In Graytone mode, the actual gray level of each pixel is scanned; 256 levels are recognized, corresponding to 1 byte (8 bits) per pixel. This results in graytone files that are 8 times larger than uncompressed files scanned in Line mode at the same resolution; for example, an E-Size drawing scanned in graytone mode at 300 dpi has a file size of 150 MByte, compared with typically 0.4 to

1.0 MByte for a compressed file in Line mode.

b/w modes

In these modes, the scanner outputs each scanned pixel as a single bit, either black (1) or white (0), depending on whether its gray level is below or above the threshold.

Both fixed level and 2D-Adaptive thresholding are supported.

The copy modes incorporate Dual 2D-Adaptive processing with different combinations of ADL+ Error Diffusion Halftoning, 2D- Background suppression, 2D-Auto edge enhancement and 2D- Adaptive thresholding. The copy modes are ideal scanning wide format documents that are intended for re-printing. The ADL+ Error Diffusion Halftoning supports visibility of graytones in printed output
