1. A manufacturing method of a laminated sheet having a printed layer,
given that a table that associates density data of a specific area included in image data with a burnup degree of the printed layer corresponding to the specific area at printing based on the image data is an image-burnup degree conversion table, the method comprising:
identifying the image-burnup degree conversion table that satisfies a printing condition for a laminated sheet by a processor;
acquiring printed image data that is image data for forming the printed layer of the laminated sheet by the processor;
calculating the burnup degree of the printed layer based on the image-burnup degree conversion table and the printed image data by the processor;
determining whether the laminated sheet satisfies a burnup degree standard based on the calculated burnup degree by the processor; and
if it is determined that the burnup degree standard is satisfied, forming the printed layer in accordance with the printing condition and the printed image data by a printer in response to a command of the processor.
