Selecting Profiles

When selecting a profile, you first need to consider the characteristics of the scanned images. Use the following questions as guidelines:

• What is the resolution of the images?
• Are the images primarily color, grayscale, or bitonal? Do they contain text, pictures, or a combination of the two?
• Do the images contain line drawings?
• Do you want to reproduce the background in the encoded image?
• What is the quality of the text? Is it typeset or handwritten? Is it consistent in weight throughout or faded in places?
• Are the images single page or multiple page? (PNM files, for example, may be multiple pages.)

The answers to these questions determine whether you should use a bitonal or color profile to encode the images.
