Abstract
The characteristic variations of a printer largely influence the recognition precision of code information, and the recognition precision of code information appended to printed matter cannot often be guaranteed depending on printers. To solve this problem, a printer forms a predetermined chart, and the image forming characteristics of the printer are detected from the code information recorded on the chart. A generation method of generating code information obtained by encoding information to a regular sequence of a pixel cluster is controlled in accordance with the image forming characteristics.
