Identifiable Printing Methods
When measuring labels and lots, the printing state, character spacing and contrast will influence the reading accuracy.
This section describes identifiable printing conditions.
Plain Printing Surface
Printing surface with patterns is difficult to identify.
Flat Printing Surface
Printing surface with concave convex is difficult to identify.
Character Spacing
Narrow character spacing is difficult to identify.
Contrast
A proper contrast shall be required to ensure correct reading.
