Method for improving the consistency of the color density over a printing width and inkjet printer

Abstract

The invention relates to a method for improving the consistency of the color density over the printing width of an inkjet printer (10) comprising the steps of: Printing a 2-dimensional pattern (32), wherein the 2-dimensional pattern (32) has the same nominal print density over a printing width and varying nominal print densities in printing direction; Dividing the 2-dimensional pattern (32) in multiple columns (38) across the printing width; Recording with a camera (24) at least one color value for each nominal print density in each of the columns (38); Deriving a correction curve for each column (38) from the recorded color values; and Correcting printing signals and/or printing patterns with the correction curves. Furthermore, the invention relates to an inkjet printer (10).
