Our conversion software cannot read color images.
Bad

This is a 256-level grayscale image.
Grayscale scans produce huge image files.
Our conversion software cannot read grayscale images.
Bad
Problem: customer scanned front of card
Every black pixel looks like a punched hole to our conversion software.
Remember to scan only the back side of each card.
Bad
Problem: too dark
When the scanner threshold is set too dark, speckles appear, and stains appear as black areas.
Speckles and other artifacts look like punched holes to our conversion software.
Bad
Problem: too light
When the scanner threshold is set too bright,
the punches may become irregular
and too narrow to be read accurately.
Good
No problem: card is readable
