Chapter 2. Scanning Concepts

2.5 Some Scanning Tips
Depending on the contents of your documents, basically, we can classify them into three image types.

2.5.1 Controlling The Data Size
When encountering large data size problem, try the following:

  1. Scan at a lower resolution.
  2. Set a smaller and more precise scanning area that trims dummy data.
  3. Scan only up to the capability of your output device.
  4. Use application software to convert scanned image to lower resolution, lower gray levels before saving.
  5. Use compression to save files. For example, TIFF file format contains compression schemes that are effective in reducing data size.
2.5.2 Using "Preview" Function
You can set the scanning area more easily with a whole picture of the scanned image by "preview function". Analytical data are extracted from preview data that can be used for automatic exposure, automatic type setting, automatic scope and histogram analysis. Moreover, with the MiraScan driver, you can obtain the preview of parameter change effects in the preview picture area with a pre-acquired preview image.

2.5.3 Using the "Zoom" function
You can get a close-up look at the scanning area with the zoom function. A more detailed scanning image and scanning area is set by using "zoom" function repeatedly.

2.5.4 Making adjustments
You can adjust the scanning parameters including resolution, scaling, brightness, contrast, color, tone map, mirror effect and inverse effect before scanning. You can get an instant preview of parameter change effects in the preview picture area with MiraScan driver.
