The invention discloses a process for printing of panel-shaped workpieces, in particular in the region of an edge, in which a section of a panel-shaped workpiece to be printed is subjected first of all to one or a plurality of pre-treatment stages which are selected from a) pre-cleaning, b) degreasing, c) improvement of the adhesion and wetting properties and d) reduction of the electrostatic charge, and in which the pre-treated section to be printed is subsequently printed with a desired pattern, in particular by means of inkjet printing. The invention also provides an apparatus for performing said process.

1. A process for printing panel-shaped workpieces, comprising: (a) pre-treating a section of a panel-shaped workpiece to be printed with at least two pre-treatment stages automatically selected from a group consisting of pre-cleaning, degreasing, improving of the adhesion and wetting properties, and
1. A process for printing panel-shaped workpieces, comprising: (a) pre-treating a section of a panel-shaped workpiece to be printed with at least two pre-treatment stages automatically selected from a group consisting of pre-cleaning, degreasing, improving of the adhesion and wetting properties, and reducing of an electrostatic charge, wherein the automatic selection of the at least two pre-treatment stages is controlled electronically and is based on a factor selected from a group consisting of a material type and a surface condition of the section to be printed, and combinations thereof, and(b) printing the pre-treated section with a desired pattern,wherein the factor is detected by an electronic sensor disposed upstream of the pre-treatment stages. 2. The process according to claim 1, wherein the at least two pre-treatment stages are carried out in a through-feed operation. 3. The process according to claim 1, wherein the pre-cleaning stage comprises a partial stage which is selected from the group consisting of brushing, grinding, and cleaning by means of CO2-snow blasting, and combinations thereof. 4. The process according to claim 1, wherein the degreasing stage comprises electro-mechanical wiping of the section to be printed with a degreasing agent. 5. The process according to claim 1, wherein the improving the adhesion and wetting properties stage comprises a partial stage which is selected from a group consisting of grinding and roughening, priming, corona treatment, plasma treatment, flame treatment, and application of adhesion promoters, and combinations thereof. 6. The process according to claim 1, wherein the reducing the electrostatic charge stage is carried out as a final pre-treatment stage. 7. The process according to claim 1, wherein the printing is carried out in a through-feed operation. 8. A process for printing panel-shaped workpieces, comprising: (a) pre-treating a section of a panel-shaped workpiece to be printed with at least two pre-treatment stages; and(b) printing the pre-treated section with a desired pattern,wherein: the at least two pre-treatment stages are automatically selected based on a factor selected from a group consisting of a material type and a surface condition of the section to be printed, and combinations thereof;the automatic selection is controlled electronically;the at least two pre-treatment stages comprise at least two of pre-cleaning, degreasing, improving of the adhesion and wetting properties, and reducing of an electrostatic charge; andthe factor is detected by an electronic sensor disposed upstream of the at least two pre-treatment stages.
