<p>[PROBLEMS] To improve read accuracy of invisible information printed together with visible information on a medium such as paper. To enable input of a parameter of a value more approximate to the real one into a system to simulate environment data and the like during extraction by using color data on each of the visible ink used for printing the background and an invisible bar code, the indivisible ink, and a physical medium (itself). [MEANS FOR SOLVING PROBLEMS] It is possible to easily input a parameter for simulation used in an invisible code printing support system by imaging a sample print prepared for parameter acquisition by using a "parameter acquiring device" to serve as a standard of devices corresponding to the invention of an "electronic scrap system", capturing the image into a DTP system, and reading the color data on a necessary region into a parameter DB. Since it is unnecessary to experimentally create and input the parameter and input it as a value, and since a physical medium and an ink both actually used are used as they are, their optical characteristics difficult to numericalize and the influence of the blue component emitted by an ultraviolet LED emitting ultraviolet light, which is invisible, can be inputted together as an image, the parameter having a high reproduction accuracy in actual use can be inputted, and a printed sheet with high read accuracy can be produced.</p> |
