relief printing — Leading Printing Techniques Printing is described as the method of transferring ink onto paper (or additional substrate) simply by a printing plate. A number of different printing technologies have already been developed and these can be split into four leading technologies according to the type of image carrier used. Letterpress […]

transfer of ink — The transfer of offset printing ink to the printing substrate or intermediate carrier through splitting the ink layer is mainly affected by the following parameters: the thickness of the ink layer on the offset printing plates (ink supply), the period of contact (printing speed and geometry of the printing components), […]

powder application offset printing — In sheet-fed offset printing, the conventional ink is still not thoroughly dry when the sheet arrives at the delivery pile. Consequently one of the major requirements in sheetfed offset printing is the avoidance of smearing, offsetting (transfer of ink onto the following sheet), and blocking in the pile (sheets lying […]

drying hot air in offset — One problem with offset printing is that the ink is usually not sufficiently dry after printing, and therefore direct further processing/finishing of printed sheets is not possible. In offset printing a sufficiently dry sheet that can be further processed is only achieved through special additional drying units integral to the […]
