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:
Knowing this, the best practice when creating fields is that they have, at the very least, a 7mm margin
on each size of the actual area you want to capture from. For example, an effective 30mm wide pattern
will actually be 44mm wide using these margins. The margin should be for both the vertical size and the
horizontal size.
Distance between patterns
In implementations where a lot of patterns need to be close together (a questionnaire, multiple choice
question, checkmarks, etc) it is important to understand the risk of then pen writing across multiple
fields on the paper. People using the pen may, for example, make a very broad checkmark which would
bleed over to the next field. This can cause PlanetPress Capture to detect the ink as being present, and
thus trigger whatever that field does.
