PlanetPress Capture Implementation Restrictions
This document describes the limitations of the Anoto Digital Pen & Paper Technology,
especially in regards to using it within a PlanetPress Workflow implementation. Note that these
limitations apply to any Anoto technology implementation and not just our own.
Printer limitations
Any document printed with Capture Fields (aka Anoto Patterns) must be sent through a Laser
printer. Bubble jet printers are not supported and will most likely cause reading errors with
Anoto Digital Pens. Thermal printers will not work either due to the low quality printout and the
absence of actual blank ink on the paper.
Black ink close to patterns
Because the Anoto Pen & Paper technology relies on infrared to read pure-black dots on the
paper, it is imperative that no other black ink interfere with this reading. Though it is possible to
print Capture documents on a black & white laser printer as long as there is no other ink on top
of, or close to, the patterns, this is not recommended. A color laser printer should be used, and
any elements placed close to, or on top of, the Capture Patterns should be printed in color.
Black ink can be simulated using composite colors, but should never be pure black.
