Abstract (en)
A calibration method for an industrial inkjet system, which comprises printheads (H 1,1 ,...,H N,M ) that are positioned in a matrix, comprising the steps: - selecting a printhead (H i,j ), a working parameter for printheads, a sensitive field (F) with a set of P sensitive values (V 1 ,...,V P ) which corresponds to the working parameter; - forming a calibration target by generating for each sensitive value (V k ) of the set of P sensitive values (V 1 ,...,V P ) a calibration patch (P i,j,k ), based on the sensitive value (V k ) wherein the sensitive field (F) is located; and an optical-machine-readable code (C i,j,k ) to refer to the corresponding patch (P i,j,k ) and to encode an identification (I i,j ) of the printhead (H i,j ) and the sensitive value (V k ); - jetting the calibration target and selecting a calibration patch (P i,j,r ) by comparing the calibration patches (P i,j,1 ,...,P i,j,P ); - scanning and decoding the optical-machine-readable code (C i,j,r ), which refers to the selected calibration patch (P i,j,r ) and adapting a value of the working parameter according to the sensitive value (V r ) and identification (I i,j ) of the decoded scanned optical-machine-readable code (C i,j,r ).
