System and method for stamp ordering and thermal carving

A method of ordering a stamp in a system including a host computer which is connected to a network, and a plurality of seal carving apparatuses located at a plurality of sites in such a way so as to be connected to the network, the host computer is connected to a database of a data storage device that is connected to the network, the database of the data storage device is configured to store information on user accounts, order information and operational information for the plurality of seal carving apparatuses, the host computer comprising:

• seal image creation means;
• site selection means;
• ID issuing means;
• order information registration means;
• and order information transmission means, with each of the seal carving apparatuses located at the plurality of sites comprising a thermal head having a plurality of individual heat generating elements and a control device, the control device including order acceptance means and carving control means;
• the method comprising steps to be executed by the host computer, the steps including:
• creating seal image data, in the seal image creation means, in such a way that a user using a terminal device connected to the network creates a seal image having the seal image data such that the seal image data created by the user is stored in the database of the data storage device;
• allowing the user to specify, in the site selection means, at least one of the plurality of sites where the seal carving apparatuses connected to the network are located for placing an order for a stamp, which includes where the stamp is carved, based on the seal image data;
• issuing an ID, in the ID issuing means, for identifying set contents of the order;
• registering information, in the order information registration means, on the issued ID and order information associated with the issued ID in the database of the data storage device connected to the network;
• and
• transmitting, in the order information transmission means, the issued ID to the specified at least one of the plurality of the seal carving apparatuses connected to the network,
• the method further comprising steps to be executed by each of the seal carving apparatuses, the steps including:
• in the order acceptance means, inputting the issued ID and accepting the input of the issued ID that is registered in the database of the data storage device connected to the network;
• and
• in the carving control means, performing a control process of selectively and thermally driving the individual heat generating elements with the thermal head in abutment with a porous material having an ink permeability that is non-proportional to driving amounts of the individual heat generating elements such that a non-linear correlation property between the driving amounts of the individual heat generating elements and the ink permeability of the porous material is determined, using the non-linear correlation property to create corrected gradation image data based on the seal image data and thermally driving the individual heat generating elements by a driving amount based on the corrected gradation image data, which forms a seal image on the porous material, thereby performing seal carving of the stamp ordered by the user based on the seal image data which is identified by the accepted issued ID.
