Spray printed numbers
Spray printing can be done even if the card does not have an overlay over the cards. Sequential or random numbers, contact information, barcodes are generally all thermal printed. Numbers in black on a dark background does not come out as well as spray printing on a lighter background. If this is the case we can also add a white background behind the area that will be spray printed so that the information can be visible.

Advantages:
1. Cheaper than thermal printed numbers.
2. Turnaround time is shorter than thermal printed numbers.
Disadvantages:
Cheap looking font style.
