Abstract: A system is provided in an automated machine vision inspection environment. The system includes inspection cameras and a spectrophotometer or spectrometer, both implemented to be used online to detect the absolute colors of printed portions of items being inspected. The spectrophotometer or spectrometer is aimed at a fixed spot within a field of view of one of the digital cameras of an inspection system, which has a-priori knowledge as to exactly where the spectrophotometer or spectrometer is aimed. The image taken by the camera will be used to determine whether the desired measurement spot on the decoration pattern has actually been measured by the most recent snap of the spectrophotometric data. When the vision system determines that the spectrophotometer or spectrometer was truly aiming at the correct region when it captured its inspection data, it will instruct the system to accept the color measurement and will log the related data and information accordingly. If the correct spot is not measured, the data may simply be discarded or may be kept for other uses.

Abstract: An improved inside of can curing technology is provided. One implementation uses narrowband, semiconductor produced infrared energy which is focused into the inside of the can to affect a very high-speed curing result. It uses focused high powered, radiant energy that will directly impact the coating covering the inside walls of the can to rapidly cure the coating. The curing is accomplished so rapidly that the de-tempering and annealing of the aluminum can body does not have time to occur, thus leaving a stronger can. It is therefore possible to make either a stronger can with the same amount of aluminum or a can of the same strength but with less aluminum. It is also possible to eliminate the natural gas fueled oven that is the current standard and replace it with a completely hydrocarbon-free curing alternative that has superior performance. This high powered radiant, narrowband energy will be introduced directly into each individual can where it will rapidly cure the inside coating while being completely and dynamically digitally controlled to introduce only the needed heat and to not overheat the can.
