Scanning images

06/02/09

Before you scan an image, make sure that the software necessary for your scanner has been installed. To ensure a high-quality scan, predetermine the scanning resolution and dynamic range your image requires. These preparatory steps can also prevent unwanted color casts from being introduced by your scanner.
Scanner drivers are provided and supported by the manufacturers of the scanners, not Adobe Systems Incorporated. If you have problems with scanning, make sure that you are using the latest version of the appropriate scanner driver.
You can determine the resolution for your scan using the original and final image dimensions and the resolution of your output device. Scan resolution translates into image resolution when you open the scanned image in Photoshop.
To estimate scan resolution:
Do one of the following:
For laser printers and imagesetters, multiply the printer’s screen frequency by 2. To determine your printer’s screen frequency, check your printer documentation or consult your service provider.
For inkjet printers, check your printer documentation for the optimal resolution. Many dye sublimation printers and devices that print directly onto photographic paper have an optimal resolution of 300 to 400 dpi.
Determine the ratio of the final image dimensions to the original image dimensions. For example, the ratio of a 6-by-9-inch final image to a 2-by-3-inch original image is 3.
Multiply the result of step 1 by the result of step 2.
For example, suppose you are printing to an imagesetter with a screen frequency of 85 lpi and the ratio of the final image to the original is 3. First multiply 85 (the screen frequency) by 2 to get 170. Then multiply 170 by 3 to get a scan resolution of 510 ppi. If you are printing to an inkjet printer with an optimal resolution of 300 dpi, multiply 300 by 3 to get a scan resolution of 900.
Note: Different color separation procedures might require different ratios of image resolution to screen frequency. It’s a good idea to check with your service provider or print shop before you scan the image
If your scanned image contains an unwanted color cast, you can perform a simple test to determine whether the cast was introduced by your scanner. If it was, you can use the same test file to create a color-cast correction for all images scanned with the scanner.
To identify and correct a color cast introduced by a scanner:
Make sure that your monitor has been calibrated.
Open a new Photoshop file, and use the Linear Gradient tool FPRIVATE “TYPE=PICT;ALT=Linear Gradient tool ” to create a blend from pure black to pure white.
Choose Image > Adjustments > Posterize, and posterize the blend using 11 levels.
Print the 11-step gray wedge on a black-and-white printer, and then scan it into Photoshop.
Note: You can also perform this test using an 18-percent neutral gray card or an 11-step gray wedge from a photography store.
Open the Info palette, and read the RGB values on-screen for each of the gray levels. Uneven R, G, and B values indicate a color cast.
Use Levels or Curves to correct the color cast, and then save the dialog box settings.
Open the scanned image you want to correct, reopen the dialog box you used to correct the cast in step 6, and load the saved settings.
