Safeguards
There are certain safeguards against contamination:
l PlanetPress Capture checks for pattern size and placement. If the data contains ink for a
specific pattern but the ink location does not correspond to the Capture Fields of the
document it's updating, it will fail.
l Errors can be set to stop and revert the whole current batch. If a single error occurs during
the pen data processing, it is possible for this processing to be stopped and all changes
the Capture Database reverted. In implementations where the pen signs high number of
documents, this can especially be an easy way to do this, as chances are the data will not
match in at least one case.
Conclusion
l PReS Workflow can only generate 20,000 unique patterns
l One pattern is used (locked) for each page containing a pattern.
l Processing the ink data from a pen and closing the document releases the pattern
l Most implementations will not need more than 20,000 patterns
l When necessary, patterns can be extended using multiple servers or Pattern Sequences
(as long as these are used in separate physical locations).
l It is extremely critical that contamination be avoided at all costs.
l Whenever possible, always avoid using pattern sequences unless it is absolutely
necessary to do so.
Anoto penDirector
The Anoto penDirector is a software driver provided as a download by Objectif Lune Inc. The
penDirector creates a bridge between the Anoto Digital Pen and a PlanetPress Capture
workflow in PReS Workflow.
In order to use penDirector, it needs to be downloaded from the Objectif Lune website, on this
page. This software must be installed after PReS Workflow. The setup will install a pre-
configured version of penDirector which can be immediately used with PlanetPress Capture.
The communication between penDirector and PReS Workflow is either through a folder transfer
or HTTP Post communication.
