Data generation apparatus, data generation method, and computer-readable medium for assigning a thumb index for pages of a book

A data generation apparatus for generating data to be used for bookbinding by bundling a plurality of paper sheets into a book form, comprising:

• a determination unit configured to determine based on a criterion defined in advance for a characteristic of the book whether to assign a thumb index for each page of the book;
• and
• a generation unit configured to generate, for a page to which said determination unit has determined to assign the thumb index, data that arranges the thumb index to be printed at a fore edge of the page of the book,
• wherein said determination unit determines to assign the thumb index when, as the characteristic of the book, a grammage of the pages included in the book has not more than a predetermined value.

• and
• a generation unit configured to generate, for a page to which said determination unit has determined to assign the thumb index, data that arranges the thumb index to be printed at a fore edge of the page of the book,
• wherein said determination unit compares a color of the fore edge of the each page with a color of the thumb index, and determines not to assign the thumb index when the color of the fore edge is identical or similar to the color of the thumb index.

• and
• generating, for a page to which it is determined in the determining step to assign the thumb index, data that arranges the thumb index to be printed at a fore edge of the page of the book;
• wherein it is determined in the determining step to assign the thumb index when, as the characteristic of the book, the number of pieces of classification information to which image data included in the book belong falls within a predetermined range defined based on the number of pages of the book.

A non-transitory computer-readable medium storing a program for generating data to be used for bookbinding by bundling a plurality of paper sheets into a book form, that causes a computer to function as:

• a determination unit configured to determine based on a criterion defined in advance for a characteristic of the book whether to assign a thumb index for each page of the book;
• and
• a generation unit configured to generate, for a page to which said determination unit has determined to assign the thumb index, data that arranges the thumb index to be printed at a fore edge of the page of the book,
• wherein said determination unit determines to assign the thumb index when, as the characteristic of the book, the number of pieces of classification information to which image data included in the book belong falls within a predetermined range defined based on the number of pages of the book.
