Abstract
The present invention is directed to a method for quantitative and qualitative evaluation of laser printed samples, the method comprising the following steps: a) providing (S1) a laser printed sample, b) capturing (S2) a digital raster image of the laser printed part of the laser printed sample and thereon providing digital image information that constitutes the digital raster image, c) identifying (S3) at least one distinct part within the digital image information, d) obtaining at least one image histogram for the identified at least one distinct part of the digital image information, e) fitting (S4) a probability density function on the obtained at least one image histogram, and f) determining (S5) at least one parameter of the probability density function.
