Claim of US Patent No. 9,064,202

1. A data processing apparatus comprising:
an obtaining unit configured to obtain multi-valued data, a multi-value of which shows gradation of each of a plurality of
pixels forming an image to be formed on a predetermined area of a print medium;

a dot arrangement determining unit configured to determine a dot arrangement of the plurality of pixels corresponding to the
predetermined area for each of predetermined areas, according to a unit matrix that arranges dot arrangement patterns corresponding
to the plurality of pixels, the dot arrangement patterns being used to determine the dot arrangement and being based on multi-valued
data corresponding to each of the plurality of pixels in the multi-valued data obtained by the obtaining unit; and

a layout determining unit configured to determine a layout of the dot arrangement patterns in the unit matrix depending on
a position of the predetermined area on the print medium, so that the layout of the dot arrangement patterns in the unit matrix
used for a first predetermined area and the layout of the dot arrangement patterns in the unit matrix used for a second predetermined
area, a position of which differs from a position of the first predetermined area on the print medium.
