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.
This is because the pen's camera (which captures the position of the pen)is located under the pen tip and must fully see the
pattern. The following image illustrates how the pen reads its position:
