Use of Digital Modelling of the Print for the Estimation of Quality of a Press
Abstract:At processing and reproduction of images always it is necessary to be set by questions of quality of received images. Quality of so complex object as the image is very important, but it is simultaneously enough indistinct concepts.
Depending on tasks in view it is estimated by various ways. In the submitted work quality is considered as a measure of a generality of two images, initial (original) and reproduced (the printed image). Such way allows estimating quantitative change of parameters at their transformation, i.e. the process of reproduction.
At a rating of quantitative change of parameters there is a problem to define criteria of quality of the image giving in to measurement which most full meet to system of human vision.
The ideas developed in this work, reflect interrelation between structure of the image, its perception the person, and as its quantitative representation. Proceeding from these preconditions, consideration and the decision of the research problem of parameters of printed process is spent. As against a traditional way of the control over test objects the rating of quality is made on all area of the reproduced image. For definition of parameters of quality the original way of processing of luminosity-chromatic characteristics of the image is used. It enables to establish communication between objective (physical) and subjective (visual) parameters of the image, at its reproduction that facilitates a task of reception of high-quality images.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
