Recording data generating apparatus, image recording apparatus, recording data generating method and storage medium

A recording data generating method generating recording data used for reproducing a gloss of an image by recording inclined structures on a recording medium, the recording data generating method comprising:

• converting gloss data with a first resolution having an inclined structure as one pixel into inclined structure data representing a combination ratio of a predetermined number of kinds of inclined structures;
• generating N-value quantization data representing one of the predetermined number of kinds of inclined structures by performing a halftone process of the inclined structure data of each pixel with the first resolution, N being equal to the predetermined number of kinds;
• and
• generating recording data used for recording one of the predetermined number of kinds of inclined structures for each pixel with the first resolution based on the quantization data.

A non-transitory computer readable storage medium storing a program for causing a computer to function as a recording data generating apparatus that reproduces a gloss of an image by recording inclined structures on a recording medium, the recording data generating apparatus comprising:

• a conversion unit that converts gloss data with a first resolution having an inclined structure as one pixel into inclined structure data representing a combination ratio of a predetermined number of kinds of inclined structures;
• a halftone processing unit that generates N-value quantization data representing one of the predetermined number of kinds of inclined structures by performing a halftone process of the inclined structure data of each pixel with the first resolution, N being equal to the predetermined number of kinds;
• and
• a recording data generating unit that generates recording data used for recording one of the predetermined number of kinds of inclined structures for each pixel with the first resolution based on the quantization data.
