The technology relates to advanced image signal processing. One claim recites an image processing apparatus comprising: memory for storing data representing a digital image; one or more processors configured for transforming the data by embedding a digital watermark therein, the digital watermark comprising a synchronization component and a message component; one or more processors configured for: attacking the transformed data to yield altered, transformed data; analyzing the altered, transformed data to obtain detectability measures therefrom, a first detectability measure comprising a measure corresponding to the synchronization component strength, and a second measure comprising a measure corresponding to the message component strength; based on a combination of the first detectability measure and the second detectability measure, predicting&#x2014;along one or more swipe paths&#x2014;a likelihood that the transformed data, once printed on a physical substrate, will be detectable from optical scan data representing such. Other claims and combinations are provided.
