Image scanners


Image scanner manufacturers

As their name implies, image scanners are used to scan images. The most common type is a flatbed scanner. This is a scanner where the image or document to be scanned is laid flat and the scanning device is rolled across it. Other scanners work in reverse, the document is rolled through and the image scanned as it passes.

Image scanners come in all shapes and sizes, buy only what you need.

Image scanner software

To get the image into a computer you need software. The scanner usually comes with installation software which takes care of connecting the scanner to the computer. This involves installing the TWAIN drivers. To work on the image you can use almost any graphics or drawing package commercially available. Often one will be included with the scanner.

 

Scanning information and support

How to... help and support

Now that you have a scanner, how can you best use it?

There are a few simple guidelines to follow, considering whether you scan for viewing or printing.

For viewing, and posting to the world wide web, 72 dpi or 96 dpi (dots per inch) is perfectly fine, as it keeps the file small. Save as JPG interlaced, whenever possible, to help speed up the loading of the page.

For printing purposes, a resolution of 300 or 600 dpi is best. Matching the resolution output of your printer with the scanning resolution is an easy way to get the best results. The new photo image printers can print up to 1200 dpi.

There is very little reason to scan at 2400 or 4800 dpi as these files become very big and there is little else you can do with them unless you have a high quality printer or photo setter to print them. Need help?
