PROBLEM TO BE SOLVED: To provide a printing checking sheet preparing device by which whether a two-dimensional cord has properly been printed can be judged, and also, which one of the printing parameters of a printing apparatus should be adjusted can easily be judged, and also to provide a printing checking sheet, a preparing method for the printing checking sheet, a computer program, and a two-dimensional cord preparing device.;SOLUTION: The printing checking sheet preparing device 100 is equipped with: a two-dimensional code preparing section 114 which prepares a two-dimensional code; an expanded two-dimensional code preparing section 116 which expands the two-dimensional code and makes an expanded two-dimensional code; a degraded two-dimensional code preparing section 118; a sheet image preparing section 120; and a printing section 124 which prints a sheet image. In this case, the degraded two-dimensional code preparing section 118 makes the two-dimensional code degraded to a state being hard to read, and makes a degraded two-dimensional code. The sheet image preparing section 120 prepares a checking sheet image by arranging the two-dimensional code, and the expanded and degraded two-dimensional codes. The printing checking sheet 126, the preparing method for the printing checking sheet, the computer program, and the two-dimensional code preparing device are also provided.;COPYRIGHT: (C)2008,JPO&INPIT
