Scanner Based Spectrum Estimation of Inkjet Printed Colors
Abstract:Fast and accurate color measurement devices would have benefitted printing in general and specifically commercial and industrial printing presses, however, such devices are expensive and are therefore not always available. On the other hand, a scanner is cheap and available in most print services providers, and is sometimes even integrated in the output paper path of commercial presses, e.g. the HP7500 press. It is commonly agreed that scanners are not color measurement devices - certainly not accurate ones. This paper shows feasibility of providing printer output spectrum estimation using a scanner as the measuring device. Such a method could further be used for colorimetry and color characterization. To do that we need to estimate the color specification of a scanner - or - the mapping function from the spectrum to the scanner measurements, which we will consequently invert. Unlike traditional methods that ignore the printing process, we propose to use the printer color model as a prior knowledge to perform accurate spectrum estimation. The applicability generality and high quality of the proposed method are demonstrated on two different printing processes: a Thermal Inkjet printer and an LEP (HP Indigo) press.

CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, and a vibrant interactive papers session. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper presentation.
