Display masks should be used to prevent bad dots during the scan. Bad dots lead to bad alignment and mapping. . Bad dots are:
- heavy distorted dots
- crooked dots
- elliptical dots
The scanning method "flat screen" and "curved screen" offer extensive interpolation- and extrapolation methods to "fill" missing dots. Masked dots are therefore reconstructed mathematically.
There is a tradeoff between bad dots and masked dots. If too many dots are masked, interpolation and extrapolation also causes issues. So it must be considered on-premise which kind of masking makes sense.
Masks are drawn during the calibration procedure, if the appropriate option is set:
A masked result should look like this:
We recommend to explore the post-scanning options (available from Anyblend 5) to review the impact of the mask on the scanning results as well as to adjust the behaviour of the extrapolation algorithm.
