Description:

How to change resolution and rendering method of faxes for a result more in keeping with the customer's expectations 
 

How-to:

Talking of fax quality we can act on two different parameters:  the resolution and the rendering method.

Resolution: this parameter can have two settings: 200x200 dpi or 200x100 dpi.
To change this setting you should act on the Digital Fax printer like this:
- Open the printers panel in Windows
- Select Digital Fax printer
- Right click and select "Printing preferences"
- Select the desired resolution using the "Image quality" parameter. 

Rendering: please proceed as follow:
- Open file "Stonefax.config.xml" in the folder <StonevoiceAS>\apps\stonefax\settings
- Change/add the key:
<preference key="print.RenderingMethod" value="Bitonal" />
- Save and close the file
- Restart the Digital Fax service

The value can be:
- Normal: Best for images but not so good for text (medium transmission speed)
- Bitonal: Best for text but not so good for images (fast transmission speed)
- HiContrast : Good for text and images (low transmission speed)
The default value is Normal.

In case of fax with text and images that are not black, the result may be a fax not readable.
It is possibly to modify Digital Fax to increase the contrast proceeding in this way:

- Open folder <StonevoiceAS>\Apps\Stonefax\Settings
- Backup (copy/paste) the file "Stonefax.config.xml"
- Open the file "Stonefax.config.xml" and change like follow:
    <configuration>    
        <preference key="print.RenderingMethod" value="Bitonal" /> 
        <preference key="print.GSExtraParams" value="-dNOPAUSE -dBATCH -dSAFER -sDEVICE=tiffgray -r200" />
        <preference key="print.EnableTiffDither" value="false" />
    </configuration>

- Save and close the file.
- Restart Digital Fax service and test
