In general it is recommended that you scan the image at a higher resolution than you need That way you retain the amount of information in the image and if necessary you can reduce the resolution in the imaging application after the image has been scanned and acquired Different types of images need different types of scan settings However after a certain point increases in scan resolution will not improve the output image quality For example a text image can be scanned at 600 dpi for output to a 600 dpi laser printer but a color image should be scanned at 180 dpi to be output to a color BJ printer When the image is output to a Bubble jet printer in the color or grayscale mode for example the basic resolution of the printer is halved For example for a 360 dpi printer the basic resolution is set for 180 dpi e If your image is Black amp White with no shades of gray such as line art scan in Black and White mode e If you are scanning continuous tone black and white photographs charcoal drawings or any original with shades of gray scan in Grayscale mode e For full color images such as photographs or illustrations scan in Color mode e With OCR applications using Black amp White scan mode more than 300 dpi is the recommended scan resolution e The minimum scanning width and height will vary according to the selected scan resolution For example at 75 dpi the minimum size for previewing is 9 pixels per side which is appro
