USING THE SCRIPTSERVER® PAN CONFIGURABLE WATERMARK RESOURCE

Contents | Index | About the Icons

Abstract

The ScriptServer® PAN Printing System (PAN) product supports advanced form creation and imaging capabilities. This memo describes one such technique.

Techniques Covered In This Memo

This memo covers:

• The basics of creating a form which prints a background watermark (a thumbnail sample is shown to the right). The resource and form described here ship with PAN version 1.5.1 and later; if you are using an earlier version you will need to create the form and the resource.
• Changing the text, orientation and density attributes, as well as some advanced techniques.

The form will work with plaintext as well as most PostScript jobs and Microsoft Windows applications.

Creating the Form

The form requires one resource. Create the resource and the form as follows. Each step will be described in detail in a separate following section:

1. Create a special Other Resource with PAN Administration -> Resources -> create resource. This resource is a PostScript language snippet whose function is unique to ScriptServer PAN.
2. Create a Form with PAN Administration -> Manage forms -> create form and add the resource to it.

Creating the Resource

The resource is a PostScript snippet whose functionality is tied to specific capabilities of the PostScript code generated by the ScriptServer PAN Printing System. It is a resource of type Other. In ScriptServer PAN version 1.5.1, this resource is named pan$watermark in the global resource set.

To create the resource (for versions prior to 1.5.1), create a new resource of type Other, and cut and paste the following PostScript code into it. For compatibility with later versions of PAN, name the resource pan$watermark.

So that you may use multiple forms that slightly different versions of the watermark (such as a DRAFT watermark and a CONFIDENTIAL watermark,) we recommend that you create a new resource, then use the clone feature to make a copy of the pan$watermark resource for your new form.

Be sure to leave a blank line at the end of the resource!

Creating the Form

Create a Form and add the resource to it.

Changing Watermark Attributes

The following lines (the lines repeated below which are not grayed out) in the PostScript code can be altered to change the text, size, font, density and fill state:

end

Advanced Techniques

Because of PAN's late binding and resource instance inheritance scheme, some advanced techniques are possible if resource instances are defined in the queue-specific resource sets for printers, or in a shared resource set instead of in the default global resource set. For both of these examples, there is a single form which references a single named resource, as described above.

Location-Based watermarks: Queue Specific Resources

If resource instances for the named resource are created with different text in the queues associated with different printers, then jobs printed on the form will have different text depending on which printer they are ultimately printed on.

Day-Of-Week watermarks: Shared Resource Sets

If shared resource sets are created for the days of the week and day-specific resource instances are created in them, then by changing the shared resource set associated with a queue (on a daily basis) it is possible to change the text depending on the day of the week.
