on the back cover at the bottom, check the address of the distributor. If got local's address, means local edition. If got oversea's address, that's imported one. That's how I recognize it.

what i noticed, if it's locally pressed, there will be something like "manufactured and distributed by" followed by local address ON the cover back. Or else, if the writing on the back cover say manufactured oversea but then got distributor sticker OUTSIDE the case, mean it's not pressed locally. The sticker is just to tell who distribute it in here. But sometimes there's no local distrbutor sticker. So i just checked if there's any local address written on the back cover.
