Dif Useful Height >= 1.0 X, else F otherwise

In Screening modes, this parameter is reported as "Useful Row Height is Too Short (1.5X)" when that is the case.

{7} lists the Data Safety Margin, which is the ratio of the unused error correc- tion words to the recommended (!) number of such words. Data Safety Mar- gin can exceed 100%, when the ECL is higher than the minimum recommended, or be limited to 50% or lower, even with perfect printing, when the ECL is below minimum. The grade is assigned as:

Aif Safety Margin >= 62%, else

Bif Safety Margin >= 50%, else

Cif Safety Margin >= 37%, else

Dif Safety Margin >= 25%, else

Fotherwise

In Screening modes, this parameter is reported as "Low Data Safety Margin (44%)" when that is the case.

{8} lists the Edge Accuracy measured in the Start or Stop patterns. The grade is assigned as:

Aif Edge Accuracy >= 62%, else

Bif Edge Accuracy >= 50%, else

Cif Edge Accuracy >= 37%, else

Dif Edge Accuracy >= 25%, else

Fotherwise

In Screening modes, this parameter is reported as "Poor Edge Accuracy (59%)" when that is the case.

{9} lists the Print Growth measured in the Start or Stop patterns (the growth of the dark modules or "bars"). The grade is assigned as:

Aif Print Growth is between +/- 20%, else

Bif Print Growth is between +/- 30%, else

Cif Print Growth is between +/- 40%, else

Dif Print Growth is between +/- 50%, else

Fotherwise

In Screening modes, this parameter is reported as "Excessive Print Growth (33%)" or "Excessive Print Shrinkage (-43%)" when those are the cases.
