Engraved Copperplate Printing
The printing of textiles from engraved copperplates was first practiced by Bell in 1770. It was entirely obsolete, as an industry, in England, by the end of the 19th century.
The presses first used were of the ordinary letterpress type, the engraved plate being fixed in the place of the type. In later improvements the well-known cylinder press was employed; the plate was inked mechanically and cleaned off by passing under a sharp blade of steel; and the cloth, instead of being laid on the plate, was passed round the pressure cylinder. The plate was raised into frictional contact with the cylinder and in passing under it transferred its ink to the cloth.
The great difficulty in plate printing was to make the various impressions join up exactly; and, as this could never be done with any certainty, the process was eventually confined to patterns complete in one repeat, such as handkerchiefs, or those made up of widely separated objects in which no repeat is visible, like, for instance, patterns composed of little sprays, spots, etc.

Famous quotes containing the words engraved and/or printing:
“When I received this [coronation] ring I solemnly bound myself in marriage to the realm; and it will be quite sufficient for the memorial of my name and for my glory, if, when I die, an inscription be engraved on a marble tomb, saying, “Here lieth Elizabeth, which reigned a virgin, and died a virgin.””
—Elizabeth I (1533–1603)
“It seems not more reasonable to leave the right of printing unrestrained, because writers may be afterwards censured, than it would be to sleep with doors unbolted, because by our laws we can hang a thief.”
—Samuel Johnson (1709–1784)
