Abstract: Substrates and technology for detecting printing plate misuse or mismatch. Such misuse or mismatch may result in multiple, different encoded signal being erroneously included in packaging. One claim generally recites a substrate for a package, hang tag or label, the substrate including: barcode including check digit; printed control icon, the printed control icon comprising a design printed with each of four (4) ink separations, the design comprising plurality of design elements, the plurality of design elements comprising a central element, rotation indicator corresponding to the check digit, and a plurality of registration indicators, the four (4) ink separations comprising Cyan (C) color channel, Magenta (M) color channel, Yellow (Y) color channel and Black (K) color channel; in which the printed control icon indicates a printing plate mismatch when it comprises more than one (1) observable rotation indicator. Of course, other features, claims and combinations are described as well.

Abstract: This disclosure relates to advanced image signal processing technology including encoded signals and digital watermarking. One implementation is directed to a method comprising: obtaining data representing a color area; determining that the data representing the color area, or information obtained by using the data representing the color area, indicates that the color area comprises a reflectivity of 15 percent (%) or less at or around 660 nm; generating an encoded signal, the encoded signal comprising a pattern including signal elements at various spatial locations corresponding to the color area; generating holes in the color area according to the pattern, said generating holes yield an encoded color area; and selecting a fill color for placement within the holes of the encoded color area, said selecting utilizing an encoded signal error that is associated with the color area, the fill color, and a reflectance difference at or around 660 nm between the color area and the fill color, said selecting also utilizing a color error that is associated with the color area, the fill color, and the reflectance difference. Of course, other implementations, methods, packages, systems and apparatus are described in this patent document.
