Method for Adjustment of Decorative Printing and Apparatus for Carrying Out this Method

A method for printing wood material boards, in particular wood fiber material boards, by means of a digital printing process, comprising the steps of:

• a) applying at least one layer of a first pigmented primer to the wood material boards from the at least one first batch and the at least one further batch,
• b) applying at least one layer of a second pigmented primer to the wood material boards from the at least one first batch and the at least one further batch,
• c) measuring the color values of the wood material boards from the at least one first batch and forwarding the color values to a computer program;
• d) measuring the color values of the wood material boards from the at least one further batch and forwarding the color values to the computer program;
• e) processing the color values of the wood material boards from the at least one first batch and the at least one further batch in the computer program and adapting the color values of the digital print for the at least one first batch and/or at least one further batch;
• and
• f) printing at least one side of the wood material boards by means of digital printing technology, forming a decorative layer in such a way that no color deviations occur between the printed decorations of the wood material boards from the at least one first batch and each further batch.

An apparatus for producing decorative prints of identical quality on carrier materials from at least one first batch and at least one further batch, the apparatus comprising:

• a) at least one means for applying a first pigmented primer,
• b) at least one means for applying a second pigmented primer,
• c) at least one means for measuring the color values of the carrier material,
• d) at least one means for adapting the color data, and
• e) at least one printing line having at least one digital printer for printing at least one side of the carrier material by means of digital printing technology, forming a decorative layer in such a way that no color deviations occur between the printed decorations of the carrier material from the at least one first batch and each further batch.
