							Adjusting Cropping Frames in the Image Stitch Window"Cropping" is the act of selecting the area you want to keep in an image and discarding the rest when
scanning it.
In the  Image Stitch  window, you can specify a cropping frame on the image displayed in the Preview area.

							ResolutionThe data in the image you have scanned is a collection of dots carrying information about brightness andcolor. The density of these dots is called "resolution", and resolution will determine the amount of detail your image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.5 cm).
The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less
detail.
How to Set the Resolution
You can set the resolution in the following screens.
IJ Scan Utility:
Resolution  on the 
 (Scanning from a Computer) tab or  Resolution on the  (Scanning Using the
Scanner Buttons) tab of the Settings dialog box
ScanGear (Scanner Driver):
Output Resolution  in Output Settings  on the Advanced Mode  tab
Appropriate Resolution Settings Set the resolution according to the use of the scanned image.

							Important•
If you double the resolution, the data size of the scanned image quadruples. If the file is too large, theprocessing speed will slow down significantly, and you will experience inconvenience such as lack of
memory. Set the minimum required resolution according to the use of the image.
Note
•
When you will be printing the scanned image by enlarging it, scan by setting a higher resolution than
the recommended one above.

							Color Matching"Color Matching" is the act of making adjustments so that the color tones match between the original item,
the monitor display, and the color printout. On your scanner or printer, the color tones are adjusted as shown below.
Example: When sRGB is selected as the output profile (target):
The image's color space is converted from the scanner's color space to sRGB by ScanGear.
When displaying on a monitor, the image's color space is converted from sRGB to the monitor's color space based on the operating system's monitor settings and the application's working space settings.
When printing, the image's color space is converted from sRGB to the printer's color space based on the
application's print settings and the printer driver's settings.
