IMAGING DEVICE FOR FORMATION, IMAGING METHOD AND STORAGE MEDIUM Russian patent published in 2018 - IPC G03G15/01 

FIELD: physics.

SUBSTANCE: claimed group of inventions includes an imaging device, an imaging method, and a non-timed machine-readable storage medium storing a programme to cause the system to execute the imaging method. Moreover, the imaging device contains a printing unit configured to print a graph in which patterns, each of which includes an object of imaging the first primary colour and an object of imaging the second primary colour, and relative positions in the sub-scanning direction of the object of imaging the first primary colour relative to the object of imaging the second primary colour of the patterns different from each other, and a plurality of the pieces of information to identify the respective patterns is located in each of at least three positions in the main scanning direction, a receiving unit configured to adopt one of the plurality of the pieces of information for each of the at least three positions from the user, as information relating to the correction of the colour offset between the first primary colour and second primary colour, and a correcting unit configured to correct the colour offset between the first primary colour and the second primary colour based on at least adopted three pieces of information.

EFFECT: improving the quality of the printed image by correcting the colour offset between the reference colour and the correction colour.
