Zusammenfassung:	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 and will directly impact the coating covering the inside walls of the can to rapidly cure the coating. De-tempering and annealing of the aluminum can body does not have time to occur, thus leaving 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 digitally controlled to introduce only the needed heat and to not overheat the can.
