Setting Scan to File Image Resolution

Image resolution deals with the amount of data, or pixels used when scanning an image. The higher the image resolution, the better the image looks. However, depending on where the image will ultimately be used, you may not need a high resolution image. For example, if an image will only be viewed on the web, you won't need an image that's 1200 x 1200 pixels. The following will provide guidelines on image resolutions appropriate for various delivery styles.

To set image resolution

1. In the Xerox Nuvera user interface, click Scan To File.
2. Select the Basic tab (default tab chosen after clicking Scan To File).
3. Click the Resolution drop-down menu.
4. Determine final output of image. See example guidelines below:
• Choose 1200 dpi, if image is composed mostly of text and/or line art, and final output is print.
• Choose 600 dpi, if image is composed mostly of photographic or halftoned pictures, and final output is print.
• Choose 400 dpi, if image is composed mostly of text and/or line art, and final output is the web or internet.
• Choose 300 dpi, if image is composed mostly of photographic or halftoned pictures, and final output is the web or internet.

NOTE: These are only suggested settings.

5. Make any other programming choices.
6. When you are satisfied with your settings, click <Scan>.

Scan to File Resolution

Remote copy is the use of Scan to File for the purpose of reprinting on another Xerox Nuvera system.

A local copy is created using the Copy function on the Xerox Nuvera. The local copy is equivalent to 1200 x 600 dpi scan (chosen for very high productivity with competitive image quality). Because 1200 x 600 dpi is an asymmetric image which is not conducive to integration into make ready applications, the 1200 x 600 option is not provided for Scan to File. For particularly stressful documents, local copy will generally be better than the remote copy.

The Scan to File selection between 600 x 600 dpi and 1200 x1200 dpi is a document dependent one. It is dependent on productivity, archival file size and image quality requirements. Because the coarseness of the error diffusion (diffusion dither) varies between the two resolutions, the user is encouraged to try both and evaluate pictorial and business graphic areas for digital grain and text for sharpness. Chose the resolution best suited for your application. Generally 600 x 600 dpi image quality is preferred for pictorials and 1200 x 1200 dpi for text. The preference will also vary depending upon which mode (text, mixed text and graphics, mixed text and photos) is used.

Remember, documents scanned with higher contrast and lighter (more background washout), will compress better, improving productivity and storage.
