These instructions cover using scanning hardware and software in the Daley Library Reserve Reading Room (Windows XP Professional operating system and the Macintosh operating system).

Use Policy | Getting Started | Preview and Scanning | Working in Photoshop Elements

Scanning Computer Use Policy

• These computers are for the exclusive use of UIC students, faculty or staff. Reserve Reading Room staff may request users to show a UIC I-Card.
• These computers are to be used ONLY for scanning and related work. Patrons using the computer for other purposes will be asked to leave the workstation.
• Any files left on the Reserve Reading Room computers will be deleted at the end of the day.

NOTE: You cannot print from the Reserve Reading Room workstations.

Getting Started

1. Open the scanner cover and place your document face down on the scanner. The document should be placed so that its edges are against the top and right sides of the scanner. There is an arrow in the top right corner of the scanner to remind you.
2. Close the scanner cover.
3. On either PC or Macintosh, click (or double-click) on the Adobe Photoshop Elements icon.

Previewing and Scanning Your Materials

A. You should preview your items to make sure your image is properly placed and that you're getting only the area you need before you do the actual scan.

1. From the Photoshop Elements File menu, choose
        Import > EPSON TWAIN 5...
   to begin scanning.


2. Once Epson Twain has opened, a preview scan may begin automatically.
   If you see this window:
   
   
   
   Click Cancel. Then choose Manual Mode...
   A large dialog box full of options will appear.


3. To begin a preview scan , click on the icon on the left (the one that resembles a sheet of paper with the upper right corner folded over) in the Preview square:
   
   
   
   

B. Image Type and Destination

These settings tell the scanner what kind of original item you're scanning, and the final output quality you want.

1. Image Type


• If you want to scan a color image set the Image Type to Color Photo.


• If you want to scan a black and white image


1. Click on the Image Type button


2. In the list of Image Types, select Black & White Photo.


3. In the Pixel depth box, select 8-bit Gray


4. Click OK.


2. Image Destination


• If you are scanning an image to be shown on a screen (for example: a web page or powerpoint presentation)


1. Set the Destination to Screen, Screen Vivid or Screen/Web.


2. Set the Resolution to 72


• If you are scanning an image to be printed on paper


1. Set the Destination to Laser Printer.


2. Set the Resolution to a number between 150-300.


• 150 dots per inch is fine for most scans. Try this resolution first. If you find the results unsatisfactory, try increasing the resolution to 200 dots per inch. Note that file size increases significantly as you increase the resolution.


• Note: For more information on Screen Resolution and why it is set to a lower number than Print Resolution, please read How Image Resolution Works for Images Displayed on Screens.


3. Select the area to scan.


• Adjust the selection area in the image Preview window.


1. Using the mouse, click and drag a rectangle around the area you want to scan. (The dotted line rectangle that appears is the marquee.)


2. If you want a closer look at the area to be scanned, click on the button with the magnifying glass inside the Preview box to zoom to the selected area.




3. Adjust the selected area by resizing the marquee. To resize the marquee, allow the mouse to hover over an edge or corner of the marquee until arrows appear. Then click and drag to the correct size.



4. Image Settings: Brightness, Contrast and Color


• Click on the AUTO button to automatically adjust the brightness and contrast. If you prefer to do this manually, click on the first three buttons for more options. Click Reset to reset the image to its original settings.
  
  
  




5. Adjust the image size.



The Source fields will tell you the dimensions of your original image.


• If you are scanning an image to be shown on a screen, select pixels from the units menu on the right.


• If you are scanning an image to be printed on paper, select inches from the units menu on the right. You may also choose to show size as a percentage.



If you already know the dimensions that you would like your image to have, type them into the W and H fields in the Target section. You can also use the slider bar or click on the arrows to adjust the dimensions by percentage. The W and H boxes will change automatically.




Note: It is better to resize the image now rather than after the image has been scanned, especially if you wish to increase the apparent size. Scaling an image after it has been scanned will often result in lost quality (a fuzzy or more pixelated image).

Sizing: For displaying on a screen (for example: the web or powerpoint) images should not be larger than 640x480 pixels. The file size will increase as the dimensions increase so if possible, your dimesions should be smaller than this.



6. Scan


• When you are satisfied with all of the above settings, click Scan.


• The Epson Twain window may close automatically, but if it does not, click Close.

Working with Your Scanned Image in Photoshop Elements

Your image should now be in an untitled window inside Photoshop Elements.

1. Double-click the magnifying glass to see the image at full size.


2. If the image needs to be rotated, from the Image menu choose one of the Rotate options. CW will rotate clockwise (to the right) and CCW will rotate counter-clockwise (to the left).


3. If you'd like to sharpen your image, go the Filter menu in Photoshop, and choose Sharpen -> Unsharpen Mask. In the window that opens, choose the settings that look best in the preview window and click OK.


4. When your image is finished you will need to Save your image.


• Insert a floppy diskette (PC only) or 100 MB Zip cartridge (PC or Macintosh), and from the File menu, select Save As.


• If you intend to print this scanned image on paper


1. Save your image in Photoshop format.


2. Name your image and click Save.


• If you intend to display this image on a screen


1. Save in JPEG format.


2. Name your image and click Save.


3. Photoshop will prompt you for the image quality. For Image Options, set the Quality to 5 (Medium). (You don't get much better image quality by choosing high or maximum, and your files will be unnecessarily large. The "Low" setting is not recommended.) Set the Format Options to Baseline (Standard).
