One combination disclosed in the description is an image processing method comprising: accessing a design file to obtain image data, the image data comprising a plurality of color separations or channels, in which the image data comprises at least a 1D or 2D barcode represented therein and a first encoded signal encoded therein, the 1D or 2D barcode comprising a first plural-bit code and the first encoded signal comprising a second plural-bit code; operating a barcode reader to analyze the image data to decode the 1D or 2D barcode to obtain the first plural-bit code; operating a signal decoder to analyze one or more combinations of color separations or channels of the plurality of color separations or channels to decode the first encoded signal to obtain the second plural-bit code; determining whether the second plural-bit code conflicts with the first plural-bit code; and identifying a conflict based on said act of determining. Of course, other features and combinations are described as well.
