It uses the hypercube algorithm, which is a sort of under color removal. Basically it reduces proportionally CMY if (and only if) black plus CMY surpasses the given percent. It doesn't touch the K channel. So, if an output profile has, say, 300% of ink limit and you use 350% on cmsCreateInkLimitingDeviceLink it does nothing. If the profile is ink limited to 300% and you use cmsCreateInkLimitingDeviceLink of 250%, then you obtain a maximum of 250% There are better ways to inklimit, but you need more information like drop weight. The hypercube works quite well given its simplicity. Lcms2 does include a function to estimate the ink limit of a given CMYK profile.
