2.4 Local and PC Copy Principles

This section covers the main differences between Local Copy and PC Copy operations.

	Local Copy = Scan and print the scanned document using only the
	Stylus Scan processing power. Can be connected or not connected to
V	a computer.
	PC Copy = Scan, process the scanned document in the open
	application, and print from the application.

2.4.1 Local copy process

Scan > gamma curve > color matching table > print

1.The scanner scans at 300 or 600 dpi.

2.The image data is processed through the gamma curve to remove the background color of plain paper or photo paper. Unlike the Stylus Scan 2000, this image processing includes MicroWeave, halftones, and so on.

3.The color matching table is consulted to convert RGB to CMYK.

4.The printer prints at 360 x 360 or 720 x 720 dpi, and color is full color.
