Basically yes, you just have to plan and execute this correctly in terms of production technology!
A code, numbering or personalisation under a scratch-off field can make sense for many applications. First and foremost, for the listing of prizes won or winning numbers in a competition or sweepstake. Codes are often used for access authorisations to websites or as licence numbers to activate software or online services.
The technology in detail:
Medium to large quantities of scratch tickets are cost-effectively pre-printed with the image in offset printing and then screen-printed with scratch fields. In offset printing, several individual lots are printed together on one sheet, e.g. 16 scratch-off tickets in DIN A7 format on a 350x500mm sheet. Within this number of tickets, different images can be printed under the scratch field, for example 14 tickets with "Unfortunately no" and 2 tickets with "Instant win". This method is therefore particularly suitable for classic prize draws or a limited number of different images.
However, if there are different codes throughout, they must be printed digitally. With digital printing techniques that build up height in the ink layer, such as laser toner or UV inkjet, the motif to be unveiled by a scratched off field can, however, be discreetly recognisable through the scratch-off ink in the case of strong contrasts. The image must therefore be designed as a low-contrast solid surface under the scratch field, for example, a dark grey text in a light grey solid surface. Or an orange text in a yellow solid. This ensures an equal height. So please do not print the code black on white!
Small quantities of scratch tickets can also be produced very cost-effectively and flexibly using our self-adhesive scratch label. You can even add scratch fields to printouts on your own office printer. This offers absolute discretion and maximum data protection for sensitive codes, as the information is only known within your own company. The same rules apply to the design of the code field as mentioned in the previous paragraph.
