Intelligent monitoring of the offset printing process
In this paper, we present a neural networks and image analysis based approach to assessing colour deviations in an offset printing process from direct measurements on halftone multicoloured pictures—there are no measuring areas printed solely to assess the deviations. A committee of neural networks is trained to assess the ink proportions in a small image area. From only one measurement the tra...
متن کاملShort Time Spreading of Offset Printing Liquids
Liquid–solid interactions are important for numerous natural and industrial processes in agriculture, coating, filtration, painting and printing. Understanding the effects of sequential absorption of oil components and water, in various arrangements, on porous coatings during the very short time it takes for a paper to pass through a printing machine is a prerequisite for a successful printing ...
متن کاملTwo offset printing workers with cholangiocarcinoma.
OBJECTIVES Previously, the author reported a cluster of 11 cholangiocarcinoma cases exposed to 1,2-dichloropropane (1,2-DCP) and/or dichloromethane (DCM) in an offset proof-printing company. Before that report, the association between the two chemicals and cholangiocarcinoma had not been known. The current study describes two cholangiocarcinoma patients exposed to 1,2-DCP or DCM in different of...
متن کاملThe Analysis of Printing Quality of Offset - Printing Ink with Coconut Oil Base
Abstract—The objectives of this research are to produce prototype coconut oil based solvent offset printing inks and to analyze a basic quality of printing work derived from coconut oil based solvent offset printing inks, by mean of bringing coconut oil for producing varnish and bringing such varnish to produce black offset printing inks. Then, analysis of qualities i.e. CIELAB value, density v...
متن کاملWear Analysis of the Offset Printing Plate’s Non-printing Areas Depending on Exploitation
Original scientific paper One of the most important features in lithography is the stability of the printing plates during the printing process. The offset printing plates are mainly built of aluminium foil which is processed to obtain surface structure needed for printing process requirements. Printing plate is during printing process under mechanical and chemical influence of the machine part...
