Problem 1: Always answer no

Output from commercially available printers is not as good as a photographic print so the answer to our question will nearly always be no. If we always answer the question the same way, the answer isn't very helpful. We can get around this by asking a more complicated question like "Is the printed image 80% as good as the ideal print?" The problem with this is that it is very difficult to figure out how to answer that question. Instead of making the question more complicated we could ask an equally simple question a lot of times. This is the approach we have taken and we have done it by breaking the image up into a number of tiny blocks. Then the question for each block is, "Is the printed image identical to the ideal print in this image block?" For high quality printers, the answer to some of these should be yes. High quality printers will have more yes's than low quality, so the answers to our questions are now more meaningful.
