Opis:
The text presents the basic issues of offset printing and shows instances of state of the art technological solutions from main three European manufacturers. The main objects of interest are solutions which will support profitable production of packaging products. Modern machines allow to increase production flexibility. Innovative technology facilitates cheaper machine exploitation and reduces ecological impact. Automation in production processes lead to faster and cost-ffective production, which improves competitiveness in printing industry market.

Opis:
According to lots of books, the pressure in offset printing affects the optical density and the quality of printouts. One of the quali-ty parameters is a tone value increase. An advantage of our research method is obtaining printing effects for different pressures on one printout, thus meaning for identical printing conditions. We obtained the same printing conditions through using different amounts of under-lay sheets fixed to the blanket cylinder, under a blanket. The pressure was increased from optimal settings – in accordance with the ma-chine manufacturer’s recommendation. The test printouts were printed using Adast Dominant 515, on a coated and an uncoated paper. The optical density value was measured on the tone value scale from 10% to 100% stepping regularly by 10%. For this scale the tone val-ue increase was computed. The research shows that for both types of paper the optical density and the tone value increase changes not very much above the optimal pressure recommended by the machine manufacturer. A difference in the optical density and in the tone val-ue increase is bigger for coated paper than for uncoated paper. Changes in these two parameters are negligible in places where used form 0 to 4 underlay sheets and are quite significant in the place where 5 underlay sheets were.

Opis:
The aim of this research is the application of the Method of Organizational Congruencies before and after the substitution of organic solvents with vegetable agents for the cleaning of an offset printing machine in order to assess the organizational changes. A solvent-free process is the goal of the Subsprint Project (Technology Transfer Program of the European Community). This, study shows how human and environmental health is improved by using vegetable agents, though this change may lead to some other organizational constraints such as an increase of the time needed, monotony, and repetitiveness of the technical actions involved. The authors underline ’that the knowledge of the impact of the new technology on health helps a better understanding of the resistance to the change and its further amelioration.

Opis:
The printing literature provides different values of pressure between cylinders in the printing unit and between rollers in the ink unit of the offset printing machine. Very often there is no information on whether a given value of pressure is maximum or average. Another frequent problem referred to in the printing literature is that authors do not reveal the source of theorems, equations or other important information. This article includes a set of values collected for pressure, line pressure, press clamping and the contact zone width that have been presented by other authors in their specific articles and books. It also includes definitions of pressure, line pressure, press clamping, indentation of blanket and metric clamping. In addition, the article briefly presents findings of the experimental research related to the contact zone between cylinders and rollers was carried out in the printing unit and in the ink unit until present. This article also gives publication references which provide for different equations concerned with the clamping force of cylinders, their compression or indentation, the contact zone width and the impact the specific stress-strain has on blankets.
