The following is a brief description of the principles behind machine offset printing:

Litho-offset printing is an indirect (or offset) printing process Four seasons mp3. Its functioning is based on the fact that water and grease (i.e. inks) are mutually repellent. The ink is transferred to the ink mountain. It then proceeds to the grinding unit, with its many rollers of varying diameters (whose rotating action fluidities the ink) Download Hercules.
Some rollers are also endowed with crosswise movement, ensuring uniform distribution of the ink on the plate. The plate is wrapped round a cylinder and is first processed by dampening rollers, followed by the inking rollers 좀비고 퍼스트블러드. The dampening rollers apply a thin coat of dampening water (generally a water and alcohol solution.
The inking rollers apply the ink. The inks (which are greasy) adhere only to the processed portion of the plate 안드로이드 전화. Due to the water-repellence mechanism, the water (repelled by the greasy ink) does not moisten the images. The dampening water therefore provides precisely outlined images 파워밀 2015. There is of course no constant relation between the dampening water and the ink. Relations vary as a function of other parameters, such as transfer speed 프린세스 메이커2 리파인. The relation absolutely must be balanced.
Considerable skill is required to achieve this end. The plate then transfers the images to the rubber blanket, which receives the ink but not the water 윈도우 10 정품 iso. The blanket transfers the printed elements to the sheet with the aid of the counter pressure cylinder. This method is also known as indirect (offset) printing Cookie Run.
The sheets are fed to the machine by means of a sheet feeder, featuring suction devices which raise the sheet, separate it from the underlying sheets, and place it on a slide.
The sheet position on the slide is ensured by a fence. This enables the pressure cylinder grips to take up the sheets always from the same position. This means the distances are kept uniform for all printed sheets (i.e. “register”).
Many of the operations of today’s machines are automated. These operations include paper and plate format changes, washing and adjustment of the inks by means of sophisticated control units.

When printed, the sheet is ready for later processes.
