Variable Data is a form of on-demand printing in which elements such as text, graphics and images may be changed from one printed piece to the next without stopping or slowing down the printer, using information from a database or external file. For example, a set of personalized letters, each with the same basic layout, can be printed with a different name and address on each letter. These letters can then be matched with addressed and bar coded envelopes.
Variable data printing is mainly used for direct marketing, customer relationship management and advertising. We print the piece and the variable data at the same time.
