Abstract

A coded data output apparatus comprises an image data input or generation section, a resolution parameter specifying section, a resolution parameter modifying section and an image data output section. The image data input or generation section inputs or generates data for a dot code image to be printed. The resolution parameter specifying section specifies parameter data relating to the resolution of the image data input or generated by the image data input or generation section. The resolution parameter modifying section modifies the parameter data relating to the resolution specified by the resolution parameter specifying section according to the characteristic specific to the applied plate making apparatus. The image data output section outputs the input or generated image data according to the parameter data relating to the resolution and modified by the resolution parameter modifying section.

Claims

1. A code data output method used when image data of a dot code is output from a computer to a recording apparatus for recording the dot code on a recording medium, the dot code comprising a plurality of dots each of which is respectively provided in any one of dot existing areas on the recording medium in association with data, which is reproduced in accordance with whether each of the dot existing areas includes any one of the dots, respectively, when the dots are optically read by a reading device, the computer producing the image data of the dot code in consideration of an enlarged size of said each of the dots which are supposed to be enlargedly recorded on the recording medium, when the recording apparatus records the dots on the recording medium such that said each of the dots has a predetermined size, and is respectively recorded in a corresponding one of the dot existing areas.

2. The code data output method according to claim 1, wherein the predetermined size is equal to 50% to 80% of said each of the dot existing areas.

3. The code data output method according to claim 2, wherein the predetermined size is equal to approximately 60% of said each of the dot existing areas.

4. The code data output method according to claim 1, wherein the recording apparatus is a plate making apparatus.

5. The code data output method according to claim 1, wherein the recording apparatus is a printer.
