Digital production colour printing, which is printing on a digital press using dry or liquid toners instead of ink, is now more than 10 years old. The first machines from Indigo and Xeikon were first seen at IPEX in 1993, but it was at drupa in 1995 that they really first became available. At the same drupa, Heidelberg introduced their new Quick-master 46-4 DI press that also worked from digital data, but which output using four-colour offset printing. This product could be said to have slowed down the acceptance of digital colour presses because of its better and more acceptable quality in addition to the lower priced operation.
