Opis:
Vibrations in offset printing presses are serious problem, which beside influence on machines’ parts, are also source of problems with printing process and achieving prints of right quality. In this paper construction of offset printing unit is presented. Reasons of vibrations and their types in printing units are shortly described. Moreover, this article shows the role, which some of printing unit’s elements play in resisting of vibrations appearance. There is model of printing unit of sheet-fed offset printing machine presented in here. Model is described by the system of differential parametric equations. There were computer simulations realized, that pointed conditions, which should be fulfilled, so the parametric vibrations occurred.

Opis:
In the 17th century, funeral sermons were a frequent type of public address. Over six hundred of such sermons were published in Poland at the time. They were published by presses all around Poland, so that each region is represented in the production. Consequently, funeral sermons are a good source for research in regional varieties of Polish in the 17th century. The article presents the problem on the example of printed material from Lublin, published in the press owned by Paweł Konrad, Anna Konradowa, and Jan Wieczorkowicz. The inspection of the texts has shown that they represent typical qualities of 17th-century standard Polish, as well as regional differential and frequency-based qualities. Because sermons were written not only by authors from Małopolska, it can be assumed that their language was largely influenced by editors and printers.

Opis:
There are several causes of vibration of off set printing presses. Major are cyclic work of feeders and deliveries, gaps with mechanisms for fixing plate and blanket in cylinders of printing pair and inappropriate stress between those cylinders. All mentioned above causes increased exploitation of bearings, gears driving cylinders and other parts of the printing press. The consequences of vibration are also breaking of paper web and such artefacts as doubling and streaking on the prints. In this paper printing pair cylinders of lithographic printing press are described as a two-degree of freedom model. Solution of a system of differential equations, which describes this model shows influence of vibration of printing unit cylinders on the fluctuation of the ink film thickness on the prints (magnitude of streaking phenomenon).
