SCANNING PROCEDURES
Preparation
Scanners should be turned on before computers. Shut down computers, turn on scanners and start computers again. In UCSD labs scanners should already be on! In this case leave on/off switch alone.
To access scanners:
1. Open Photoshop and use File>Import command to find the appropriate scanner
or,
2. Look for a scanning software icon somewhere on the desktop or for Macs in
the Apple Menu.
To Use Flatbed Scanner
Place image in scanner face down, near the arrow and ruler guides.
Look at the menu in the scanning software and make sure the appropriate type of scan is selected, line art, gray scale or color. If you're scanning in color, make sure that the prescan is also set to color. Note if you use line art you will get a bitmapped image and will have to change the file type in Photoshop using Image>Mode>Grayscale.
Press PRESCAN.
When your scanned image appears, set the outline of the image using the cropping tool. In software such as Scan Wizard, you can grab the lines of the rectangular box. Remember that it's better to scan too much and precisely crop in Photoshop.
Set the appropriate resolution and scaling. The resolution for web work is screen resolution, 72dpi. You will see a box something like the one below:
| width |
scale
|
| height |
MAKE SURE THE SCALE IS SET ACCURATELY!!!! If in doubt make sure it's at 100%. If you're getting a tiny scan, this is probably the reason.
Press SCAN
To save your image, use command File>Save As in Photoshop. Be careful to select names for your images that will help you remember what they are. Make sure that you save to a disk! If you want to work on a PC, remember to use no more than eight letters in name and add .psd. Generally you should save in Photoshop format.
Note: The scanner also has controls for contrast and color correction that are similar to those in Photoshop. After you are familiar with these tools in Photoshop you can experiment with the scanner controls. While it is supposedly better to correct a scan during the scanning process, the tools in Photoshop are both easier to use and more sensitive and hence unless there is a severe problem, I recommend using the Photoshop tools.
