Determing Resolution

The data in the image you scan is a collection of dots carrying information about brightness and color. The density of these dots is called "resolution," and "dpi" (dots per inch) refers to the number of dots in one inch.

You can specify a resolution in [Image Quality] in the MF Toolbox settings dialog box, or in [Output Resolution] in the ScanGear MF.

Images for Display on a Monitor

Images for display on a monitor in general should be scanned at a resolution of 75 dpi.

Images for Printing

Images to be printed should be scanned at a resolution which corresponds to the resolution of the printer.

With a color printer, the colors are expressed as a certain percentage of ink pigment so scanning your document at half the resolution of the printer should be fine.

Printing Scale

For example, if you want to print a document which is twice the original size vertically and horizontally, the resolution of your document will be reduced by half. In such a case, scan the original document at double the resolution so that you can print the document with sufficient quality, even if you double the size of the document. Conversely, if you want to print a document at a reduced size, it should be sufficient to scan at half the resolution.

Resolution and Data Size

If you double the resolution, the image data will be four times greater. If the data is too large, processing speed will slow down significantly, and you may experience malfunctions such as lack of memory. Make sure the resolution corresponds to the purpose of use of the image and set at the lowest level possible.
