In order to solve the two-dimensional code in different scenarios to meet the needs of multi-code integration,anti-counterfeiting tracing,information value-added,and other multiple applications,and to meet the code scanning software and hardware system compatibility,a new color two-dimensional code which can be read directly was designed in this study.The two-dimensional code was coded by color information,and a clear code and two dark codes were combined to produce a clear code which can be directly read in visible light.At the same time,under the condition of a colored light source or filter gated,the two dark codes can be read directly by scanning the codes.The clear code can be used to record the public information on commodity labels and other items,and the two dark codes can be used to record special information such as the source of anti-counterfeiting,information value-added services,and so on.In this study,the basic principle and design technology of the two-dimensional code were given and the related technical difficulties in its design were solved.Through the print test,the expected design target requirements can be extended.
