Process-Based Sequences: In this case, while documents are still printed and their route num-
ber attributed to their pattern sequence, the pens do not have this distinction. However, the dock-
ing station where the pens are placed at the end of the day are set to send the pen's data to a
specific process which will only handle processing for that specific route number. In this case,
one physical computer (and, presumably, printer) is used for each route, and the driver must
dock the pen in the proper docking station which corresponds to his router number, at the end of
the day.
As you may have figured out by now, we are still not actually printing more than 20,000 patterns. The
only distinction here is that we are re-using patterns in separate "zones" (or, well, sequences) and as
long as pens and pages using capture patterns are not exchanged between these zones, they act inde-
pendently with their own 20,000 pattern limitation.
Note: The mobile phone application, "PlanetPress Mobile", which uses Bluetooth communication
to receive pen data and transmit it to PlanetPress Workflow, can still be used with both pattern
sequence methods, as it is the equivalent of a docking station on the web. PlanetPress Mobile
was added to PlanetPress Capture in version 7.4.
Contamination
The single but critical danger with any implementation that deals with PlanetPress Capture is "Contam-
ination". Basically, contamination happens when an Anoto Digital Pen writes on a "wrong" document or
is docked in the wrong location. This can happen any number of ways and in different situations, and
can have devastating effects in some of those cases so please pay special attention to this section.
First, contamination is not limited to implementations that extend their patterns through methods 1)
and 2) above. Any time that a pen writes on a "wrong" document, it is considered contamination. A
simple example in a basic implementation would be to print a document with a pattern on it, put this
paper aside (or lose it on a desk somewhere) and forget about it. Assuming proper processes were put
in place, this document would eventually be closed by a manual or automatic procedure. However, the
physical document with the pattern still exists even if it is closed in regards to the PlanetPress Capture
database. Contamination would happen if a new document is printed with the same pattern, but some-
how the "old" document re-surfaces and someone writes ink on it and docks the pen. When this hap-
pens, neither the pen nor PlanetPress Workflow can understand that the data does not belong on that
document and will happily update the "current" document, possibly closing it. Because the "old" doc-
ument relates (presumably) to a different client, this means the "current" document has invalid inform-
ation.
This can be prevented through simple methods such as printing a date on each sheet and ensuring that
users never sign a document that is older than a certain time, for example 48 hours. These sheets
should simply be destroyed.
