If you are scanning for the web, keep files small so your web page will load as quickly as possible. The accepted resolution for web images is 72dpi.
For greyscale (black and white) photographs and for colour images that will be used in a printed project, 300dpi is preferred.
For line art (black and white only images that have no shades of grey), 600dpi is the preferred resolution.
RGB is the default colour setting for most scanners. It’s fine for web images but not acceptable for printed projects. Remember to change the setting to greyscale for black and white photographs or for colour images that will be reproduced in black and white. Use the Black & White setting for line art.
For images that will be printed in colour, either use the CMYK setting or use an image editing application such as Photoshop to change the colour mode from RGB to CMYK. This is important.
