							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 of the Settings dialog box
ScanGear (Scanner Driver):
Output Resolution  in Output Settings  on the Advanced Mode  tab

							Data FormatsYou can select a data format when saving scanned images. You should specify the most suitable data
format according to how you want to use the image on which application.
Available data formats vary by application and operating system (Windows or Mac OS).
See below for the characteristics of each image data format.
PNG (Standard File Extension: .png)
A data format often used on websites.
PNG is suitable for editing saved images.
JPEG (Standard File Extension: .jpg)
A data format often used on websites and for digital camera images.
JPEG features high compression rates. JPEG images slightly degrade every time they are saved, and cannot be returned to their original state.
JPEG is not available for black and white images.
TIFF (Standard File Extension: .tif)
A data format featuring a relatively high compatibility between various computers and applications.
TIFF is suitable for editing saved images.
Note

						

							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.

type of item to be scanned. Otherwise, items may not be scanned correctly.
Important

						

							Placing Multiple Items:
Allow 0.4 inch (1 cm) or more space between the edges
(diagonally striped area) of the platen and items, and
between items. Portions placed on the diagonally striped
area cannot be scanned.
 more than 0.4 inch (1 cm)
