Paper quality
The PlanetPress Capture technology, when generating the Anoto Pattern, already accounts for
ink dispersion on laser printers and on general-use laser paper. Therefore, using paper that is
not of the same quality (for example, one where the dispersion rate is much higher) or the same
type (reflective paper)may not permit the pen's camera to read the pattern properly.
Pattern sizes
The absolute minimum required for an Anoto Digital Pen to read the pattern and know it's
position on the page is 7mm (1/4"). Any pattern smaller than this will not be readable. However,
at 7mm width and height, the pen can only recognize a single dot within that pattern, at the top
of the field.
