Changing the Original Document Source
The Original Document Source setting identifies the item you want to scan.
You can choose from the following settings:
Flatbed Reflective: Scans paper originals (non-transparencies) e.g., photographs, documents, and
brochures.
UTA (Transmissive): (Astra 3450 only) Scans transparent objects through which light can pass (e.g.,
35mm slides). Optimum quality is achieved by making sure your Frame (see Frame Tool p.18) does not
extend beyond the image area of the transparent material.
UTA (Negative): (Astra 3450 only) Scans photographic negatives or films. Optimum quality is achieved
by changing the Image Mode (see below) to “True Color, 42-Bit RGB” and making sure your Frame (See
Frame Tool p.18) does not extend beyond the image area of the film negative.
Automatic Document Feeder: The Automatic Document Feeder option is not available with the Astra
3400 or 3450 scanners.
Changing the Image Mode
VistaScan can scan a wide variety of image types.
True Color, RGB: Scans a full color photo or document. The RGB indicates the colors of Red, Green,
and Blue. This setting creates larger files that the B/W Photo setting.
True Color, CMYK: Converts RGB (video) color data into CMYK (printed) color data using a special
color transformation process. When scanning is completed the CMYK image is ready for printing on a
CMYK color printer.
NOTE: Most ink jet printers use RGB rather than CMYK printing.
256 Colors: Scans color images using 256 colors. The 256 color images take up less memory and hard
disk space than the True Color RGB option.
