<p>[QUOTE="Daggarjon, post: 583054, member: 4230"]very nice links! i have known for a while that the Eurion is not the only factor stopping scanners from scanning currency, or as the one site put it, it may not even BE a factor. I have also known for a while that the culprit scanners use is a watermark of some sort, although i was under the impression it was 'hidden' in a specific color wavelength. The one site stakes claim to it being hidden in a certain 'histogram' characteristic, although identical histograms dont share the scanner block. I think the Histogram theory holds weight, although i still believe a color wavelength is being used either by itself or in combination of somethign else. try scanning a note while completely blocking certain colors wavelengths... i promise the results can be amazingly different then what they eye sees on the paper note!</p><p><br /></p><p>and no, Dave, its not really a sore subject, it actually a good idea to keep the conversation going so as new theories and finds are ... well, found, they can also be shared <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /> while it is very frustrating to not be able to perfrom 100% legal activities, i am also up for any challenge. (ive never stated to be a 100% LAW ABIDING CITIZEN!!!) And if folks want to ban legal activities, then the more of an outlaw i shall become!</p><p><br /></p><p>For the moment, i am looking into a new flatbed scanner. I cant believe how difficult they are to find in stores. All that are sold these days are all in 1 pieces of junk! I am sorry, but it they sell flatbeds for $200 or more, how can they sell a gadget that scans, copies and prints for $75?? I have a possible answer to that... they make them all in 1's out of recycled baby bottle inserts and recycled baby diapers... both uncleaned.... sorry for the mental image <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /> but that what the all-in-1's turn out to be! I kep my Euro and Canada $5 notes handy anytime i go to a store to test a scanner. I also have a copy of the legalese saying its legal to scan ... just in case anyone from management inquires as to what on earth i was doing lol</p><p><br /></p><p>On the subject of trying to protect printed images would be almost impossible.
