Scanning

Scanning is the process of converting printed material (i.e. photographs, postcards) into digital images  that can be manipulated using graphics software. To scan a document, you must have a computer with a scanner connected to it and scanning software. The scanner imports the printed material into the computer and the software allows you to manipulate and edit the scanned image.

A note about scanning for the web. Monitors display from about 72 to over 100 pixels per inch. You can and should scan at higher resolutions if you wish the image to be larger than the original, or if you want to print the image too. After your image is the size you want, resave for the web specifying the pixel size. So if you are scanning for print and web, scan as high as is practical. When you optimize your image for the web, the difference in dpi makes no difference in file size when you are saving images for the web as .jpg, .gif or .png. Your original image, scanned at the highest practical resolution, can be saved as a .psd (which will save the dpi information) in PhotoShop and used for print too.

Scanners are available at the Student Microcomputer Facility in FAC 212. Instructions for using the scanners are located at each scanning station. To use any of the computers in this lab you must have a user number with PRS (Print Relay System) service. If you are a student and have a valid UT ID, but need an IF user number, talk to an SMF proctor. Faculty and staff must obtain PRS validation at FAC 248.
