Adjusting Cropping Frames
Adjusting Cropping Frames
You can specify the scan area by creating a cropping frame on the image displayed in the Preview area.
When you click Scan, only the portion within the cropping frame will be scanned and passed to the
application.
You can create two or more cropping frames. When you click Scan, all cropping frames will be scanned.
(Scan is repeated for each cropping frame.)
Important
You cannot create additional cropping frames when you used Multi-Crop in ScanGears Advanced
Mode.
Cropping frame types
(1) Focus Cropping Frame (rotating thick broken lines)
The settings in Basic Mode or Advanced Mode will be applied.
(2) Selected Cropping Frame (stationary thick broken lines)
The settings will be applied to the Focus Cropping Frame and Selected Cropping Frames
simultaneously. You can select multiple cropping frames by clicking them while pressing the Ctrl key.
(3) Unselected Cropping Frame (stationary thin broken lines)
The settings will not be applied.
Initial cropping frame
A cropping frame (Focus Cropping Frame) is displayed automatically around the preview image
according to the document size. You can also create a cropping frame by dragging the mouse in the
Preview area.
Adjusting a cropping frame
The cursor will change into  when it is positioned over a cropping frame. If you click and drag
the mouse in the direction of the arrow, the cropping frame will expand or contract accordingly.
The cursor will change into  when it is positioned within a cropping frame. Click and drag the mouse
to move the entire cropping frame.
You can rotate a cropping frame 90 degrees by clicking 
 (Switch Aspect Ratio). However,  (Switch
Aspect Ratio) is not available when Output Size is Flexible.

							In Advanced Mode, you can specify the cropping frame size by entering the values into  (Width) and 
 (Height) in Input Settings.
Note
Cropping frames are set according to the document size (Auto Crop) by default. For details, see
Cropping Frame on Previewed Images in Preview Tab (Preferences dialog box).
Creating multiple cropping frames
Click and drag the mouse in a space outside the existing cropping frame to create a new cropping frame
in the Preview area. The new cropping frame will be the Focus Cropping Frame, and the old cropping
frame will be the Unselected Cropping Frame.
You can create multiple cropping frames and apply different scan settings to each cropping frame.
You can select multiple cropping frames by clicking them while pressing the Ctrl key.
If you select multiple cropping frames and change the settings on a tab at the right of ScanGear (scanner
driver), the settings will be applied to all the selected cropping frames.
When you create a new cropping frame, it retains the settings of the latest cropping frame.
Note
Create up to 10 cropping frames.
Scanning takes longer than usual when multiple cropping frames are selected.
Deleting cropping frames
To delete a cropping frame, select it and click  (Remove Cropping Frame) on the Toolbar.
Alternatively, press the Delete key.
When there are multiple cropping frames, all the selected cropping frames (Focus Cropping Frame and
Selected Cropping Frames) are deleted simultaneously.

Resolution
Resolution
What is Resolution?
The data in the image you have scanned is a collection of dots carrying information about brightness and
color. 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 square
inch (2.54 cm square).
The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less
detail.
Setting the Resolution in MP Navigator EX
In MP Navigator EX, you can specify the resolution with Scanning Resolution in the Scan Settings dialog
box.
Images for Printing
Images to be printed should be scanned at a resolution that corresponds to the resolution of the printer.
For example, if you want to print using a 600 dpi black and white printer, you should set the resolution to
600dpi.
With a color printer, specifying the resolution at half the resolution of the printer should be fine. For
example, if you want to print scanned paper/photos using a 600 dpi color printer, you should set the
resolution to 300dpi. However, with a high-resolution printer, printing takes longer than usual if you set
the resolution to half the resolution of the printer.
Example of Appropriate Resolution when Printing to Scale
If you print a document at twice the size both vertically and horizontally, the resolution of the document will
be reduced by half. If the resolution of the original document is 300 dpi, the resolution of the enlarged
document will be 150 dpi. If you print the document with a 600 dpi color printer, the lack of detail in the
image may be obvious. In that case, if you scan at the Scanning Resolution of 600 dpi, the resolution will
be 300 dpi even if you double the size of document and you can print the document with sufficient quality.
Conversely, if you print a document at half scale, it should be sufficient to scan at half the resolution.

Scanning resolution: 600

Setting the Resolution in ScanGear (Scanner Driver)
In ScanGear, you can specify the resolution with Output Resolution in Output Settings on the Advanced
Mode tab.
Page 574 of 805 pages Resolution
 
						

							Example of Appropriate Resolution when Printing to Scale
The scanning resolution is automatically set so that the value set in Output Resolution will be the
resolution of the scanned image. If you set Output Resolution to 300 dpi and scan at twice the size, the
document will be automatically scanned at 600 dpi, and the resolution of the scanned image will be 300
dpi. You can print the document with sufficient quality using a 600 dpi color printer.

Note
Although you can change Output Resolution in ScanGear (scanner driver), it is recommended that
you scan at the default value.
If you double the resolution, the file size quadruples. If the file is too large, the processing 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.

File Formats
File Formats
You can select a file format when saving scanned images. You should specify the most suitable format
according to how you want to use the image on which application.
Available file formats vary by application and computer (Windows or Macintosh).
See below for the characteristics of each image file format.
BMP (Standard File Extension: .bmp)
A standard file format for Windows.
BMP is often selected for images that are used only on Windows.
JPEG (Standard File Extension: .jpg)
A file 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.
Exif (Standard File Extension: .jpeg)
A file format supported by many digital cameras.
It adds information such as the date of image capture, camera model, shutter speed, shooting mode
and comments to JPEG files.
The file format version must be Exif 2.2 or later in order to print on a Direct Print compatible printer.
TIFF (Standard File Extension: .tif)
A file format featuring a relatively high compatibility between various computers and applications. (Some
TIFF files are incompatible.) TIFF is suitable for editing saved images.
Note
MP Navigator EX supports the following TIFF file formats.
- Uncompressed, black and white binary
- Uncompressed, RGB (8 bits per channel)
- Uncompressed, YCC (8 bits per component)
- Grayscale
PDF (Standard File Extension: .pdf)
A file format developed by Adobe Systems. It can be used on various computers and operating systems.
Therefore, PDF files can be exchanged between people who use different operating systems, fonts, etc.
regardless of the differences.
Note
Only PDF files created with MP Navigator EX are supported. PDF files created or edited in other
applications are not supported.

Color Matching
Color Matching
Color Matching adjusts devices as shown below to match the colors of an image displayed on a monitor
or a printed image with the colors of the original document.
Example: When sRGB is selected as the output profile (target)
Input Profile (Source)
 Scanner 
ScanGear (Scanner Driver)
Output Profile (Target)
 sRGB 
OS
Application
 Application
Printer Driver
Monitor Printer
ScanGear (scanner driver) converts the images color space from the scanners color space to sRGB.
When displaying on a monitor, the images color space is converted from sRGB to the monitors color
space based on the operation systems monitor settings and the applications working space settings.
When printing, the images color space is converted from sRGB to the printers color space based on the
applications print settings and the printer drivers settings.
