Digital BW, The Print

To calibrate, I was always told, is to measure and adjust the accuracy of an instrument against a standard. To linearize, in my understanding, is to plot output values against input values so that the output function is orderly and reliable.  To differentiate a bit more,   the first is a way of establishing validity, i.e.--is the device (and its operator) accurately measuring what it is intended to measure. The latter has more to do with reliability, i.e.--will repeated outputs be the same for the same given input. That said, the real value of all of this to me is in providing operational definitions of the steps you perform in doing your work: the procedures, measurement methods, materials and equipment you use to get a specific result.
