Print Data Validation (PDV) is a file-based verification of multi-lane variable data fields on cut sheet and roll-to-roll print applications. Real-time variable data verification, performed immediately after printing, provides the only viable solution for 100% checking and the verification of correct sequencing and print quality of variable printed data on high speed printing and finishing machines.

Discovery Print Data Validation (PDV), operating in combination with Discovery Multiscan, is an in-line variable data integrity and print quality inspection tool, ideally suited for sheet-fed or web applications with defined repeats containing multiple variable printed fields on each item.
Discovery PDV compares all of the variable data (up to 400 fields) on a sheet or web repeat to a data file and reports on any data errors, missing or duplicate sheets found during the production run.

A Discovery PDV solution gives you the confidence that your print data meets your customers’ specification, reducing your liability and waste, while improving your productivity, efficiency, and profitability. It provides the most comprehensive, adaptable and powerful solution on the market for verifying the integrity of print jobs running large volumes of variable data to ensure your printing is always 100% accurate.

Lottery, gaming, phone cards, tax stamps or security print applications typically consist of serialised printed sheets/web repeats, each with multiple variable data fields. All variable data is driven by a data file, consisting of data records identifying the individual sheet or repeat number, with multiple data fields related to each record. The Discovery PDV identifies the specific sheet or web repeat, reads all the variable data fields on every item on the sheet/repeat and reconciles it to the original data file.

In the event of a mismatch being identified, the nature of the error and its location is logged, the operator is alerted and either the web is marked or the sheet is diverted. Discovery PDV reports on the number of sheets/repeats seen, the status of each sheet or repeat, each data record and each data field. The data is readily available in common formats for importing into most MIS or report generation platforms.
