Abstract

Abstract The ultimate goal of each production process is to optimize all the subprocesses leading to the high quality final product. Within the printing process, dot gain is identified as one of the most important variables to control because of the extremely negative impact to middle tone contrast and the overall reproduction. Dot gain consists of two components, mechanical and optical dot gain, as a result of two different contributions. This article proposes a model for separately analyzing components of dot gain for electrophotography prints using gradient method, where the impact of printing technique and paper type will be examined. It is shown that mechanical dot gain for electrophotography prints can be satisfactorily approximated with Gaussian, whilst optical dot gain is once again confirmed to have the form of a Lorentzian.
