Tips & Hints for Using Your Scanner

Scanning

To get the best possible scans, there are several factors other than the scanner that will influence how
you view the image.

1. Your graphics card will affect the way you see the image. The more colors you can display, the

better. If you can, set your video to 16-bit Hi Color or 24-bit color True Color. 16-bit color allows
the computer to use thousands of shades or variations of color. 24-bit allows millions of color.
Contrast this with 256 colors or, worse yet, 16 colors.

2. For visual part of the display, having an SVGA monitor is infinitely better than a VGA monitor

(capable of displaying better resolutions & colors).

3. On some computers and with some originals, you can get a better image if you adjust the gamma,

brightness, contrast and/or other effects.

4. The graphics program that you are using to scan can also effect the image, especially after you

have scanned it. Some more advanced graphics programs will allow you to adjust several effects
in your image: sharpening, auto-cropping, descreening and other image corrections. Whether you
need to use some of these effects will depend on your use for the image and the quality or source
of the original. The process of scanning will magnify any flaw in your image, even if that flaw is
not readily visible when you look at the image without any magnification. For example, scanning
magazine pictures will often reveal a moiré pattern because of the resolution of the original and
the process used in the printing (moiré will often look almost as if someone has a dirty screen laid
over the image). Moiré can, in some instances, be corrected through de-screening either during
the scanning process (refer to Scanner Operation) or in more advanced graphics programs after
the image is scanned (such as in Ulead Photo Impact).

Printing

If you are going to be printing your scanned image, there are some important things to keep in mind
for both your printer and while scanning.
1. A printer capable of higher resolutions and more colors (16-, 24-, or 30-bit color) will give you a

truer image.

2. A printer which is capable of higher resolution will also improve your printed output. You may

have to use special paper to get the best results or to achieve the higher resolution setting of your
printer.

3. Scan at the resolution of the printer (i.e. if the printer is 300dpi scan at 300dpi).
4. Make sure your scanned image does not exceed the available printing area of your printer (all
