DIRECT PART MARKING APPLICATIONS
For Data Matrix family codes the Decoding Complexity parameter is available when
Processing Mode is set to Standard and selects the decoding algorithm according to the
printing/marking technique used to create the symbol and on the overall printing/
marking quality.
The possible selections progress from Low to Very High where Low can improve decod-
ing time for good print/mark quality and/or relatively normal size codes. This is the
default setting. Very High can improve the decode rate for low print/mark quality and/
or small size codes. This algorithm is much more aggressive but in general it may have
longer decoding times than the lower complexity algorithms. To minimize decoding
time it is better to select the lowest value that still guarantees good decoding.

For QR code the Decoding Method parameter allows the Dot Peen Decoding algorithm
to be selected which improves the decode rate for low quality Direct Part Mark codes
and in general for Direct Part Mark codes with dot peening type module shapes.
