OID printing requirements
2.1Equipment Requirement
OID_ ll: The resolution of image setter is recommended to be NOTLESS than 1200dpi (dot per inch)
2.2 Paper Quality Requirement
Smoothness of paper that can support 600 dpi resolution printing is crucial on OID II system. Heaviness of the paper is not the primitive concern on OID II system
1.For better " reading and decoding" performance, it is recommended to use ART-COATED Paper
2.OID II can also apply to general office use A4 size paper.
2.3 Size of OID II DOTs
To have best sensitivity from OID II system, the diameter of the DOT should be well controlled within the range of 40um to 80um, as shown below. Detection angle is likely to be deteriorated if the diameter fell out of recommended range. For example, 0 to 45 degree can be achieved under conventional printing process while 10 to 35 degree can only be expected under poorer printing quality.
Remarks:
Printer of factory has to pay special attention to the INK intensity and the accuracy of the index film.
