Scanned images with the following problems will be rejected.
(Note that these examples only apply to Method 2, Card Reading over Internet.
If you are mailing your cards to us, don’t worry about these examples.)
Bad | Problem: image is in color
Color scans produce huge image files. Our conversion software cannot read color images. | |
---|---|---|
Bad | Problem: image is grayscale
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
This is a two-tone (also called bi-level, black-and-white, B/W, line art) scanned image. TIFF files prepared in this way should be no bigger than 20k bytes per card. |
