My point precisely. It's a setting you'd find when saving out a grayscale photo in certain file formats, and it's not important unless you're professionally press-printing; even then, if you're printing at decent quality, it doesn't matter much. It developed in newspapers, because the paper is so cheap that the ink spreads dramatically, so they had to make some serious adjustments in halftone photographs to allow for the extra amount the ink was going to spread out from each halftone dot, in order not to get a dark morass of ink where their photo should be.
If you're printing on an offset press with decent paper, it's a non-issue to anyone who isn't wearing a loupe. With good paper, especially with coated paper, there's little to no spread from where the ink is laid down.
