Description:

How to change fax resolution and rendering method to improve fax quality and meet customer's expectations. 

How-to:

Fax quality can be tuned through 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 access 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

Accepted values are:

• 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
