Image Quality
To create a higher-quality image that is better able to display fine-print text, go to the Options menu Device tab and click Video Size. Set the video size at the highest setting. Note that this will cause the software to "stutter" very strongly when you move what is beneath the camera. Do not use this setting for video capture.
For the absolute highest quality image, use the TIFF format following the steps below.
File Type
To change the type of file created to store your image, go to the Options menu. Choose the Snapshot or Snapset tab depending on whether you want to capture a single image (Snapshot) or a series of images (Snapset). Change the Image Format to your desired file type.
The default file type is PDF. PDF is the easiest format for quickly browsing a page. If you want a file that can be easily edited in a program like Paint of Photoshop, use an image format such as TIFF, PNG, or JPEG. For a basic-quality image, use PNG or JPEG. For a very high-quality (and larger file size) image, use TIFF.
