ICC Profile Extension for Device MTF Characterization

We propose a method to maintain image sharpness consistency across different devices, analogous to the way ICC profiles are used to maintain color consistency. The method is based on creating a profile of the perceived blur caused by the printing and viewing process. We show how to measure and analyze the sharpness profile of a printer, and demonstrate that the profile consists of multiple 2D modulation transfer functions (MTF's), varying over different ink combinations and colors. We propose storing the sharpness profile within an ICC profile. The profile can then be used to adaptively pre-compensate for the induced blur, and maintain sharpness consistency.
