IV. Which term does each definition refer to?

a) It consists of an ink duct or ink fountain, a doctor blade, a plate cylinder, an impression cylinder, and obviously the material to be printed on. The plate cylinder is provided with a copper layer or shell, in which little engraved cells are made. These cells have to be provided with ink. This can be done in several ways. The plate cylinder could rotate in the ink duct, but it also occurs that the plate cylinder is sprayed with ink, or is provided with ink by the form rollers. After the process of inking, there is ink not only on the engraved cells, but also in other places outside these cells. For that reason excess ink is scraped off by a doctor blade. The paper web is wound off the roll and carried through the printing unit, in between plate and impression cylinders.

b) A thin strip made of steel used to regulate ink flow on flexographic and gravure press.

c) Printing technique where the image is engraved into a copper and chrome covered cylinder. From there the ink is directly transferred to the printing material

d) High quality analog black and white, colour analog, black and white digital or colour digital drawings.
