An intaglio or recessed printing process. The recessed areas are like wells that form the image as paper passes through.
A printing process used in high-output rotary presses, in which the printing elements take the form of small cells on the surface of the gravure form cylinder. The print image is generally transferred onto the cylinder by means of electromechanical engraving using a diamond stylus. During the course of the printing process, the printing cylinder is entirely coated in ink. A doctor blade then removes the excess ink from the surface and the only ink remaining is the ink in the cells. A rubber roller then presses the paper web against the printing cylinder and the ink remaining in the cells is applied to the paper.
The depressions in an engraved printing cylinder or plate are filled with ink, the excess raised portions being wiped off by a doctor blade. Ink remaining in the depressions is deposited on the plastic film or other substrates as it passes between the gravure roll and resilient back-up roll.
Also rotogravure printing or intaglio printing. Uses a sunken or depressed surface for transferring the image. A copper wrap-around plate or cylinder with the image etched below its surface rotates in a bath of ink. The excess is wiped off the surface by a doctor blade. The ink remaining forms the image by direct transfer to the paper. By contrast, letterpress printing uses a raised surface and offset printing uses a flat surface.
a machine printing process often used for wallcovering. The copper printing rollers are engraved with a design and then plated with chrome for hardness. The engraved or recessed areas of the rollers pick up the ink and deposit it on the wallcovering surface. There is a separate roller for each color, and the depth of the engraving determines the strength of the color. This means that each roller or cylinder is capable of printing tones of that color. Gravure machinery usually allows up to eight printing rollers/cylinders which print the wallcovering as it passes through the machine. The machinery runs at high speed and the ink is applied and then runs through a dryer before the next color is printed. This process allows for very fine detail and reproduction of images with photo quality.
A high-speed, cost-effective and the most common wallpaper printing process; utilized copper cylinders, with one color per cylinder, etched with the pattern design; can achieve fine detail and a wide range of tones in as many as 12 colors.
This printing process uses an etched cylinder to transfer ink to a substrate.
A process in which the printing areas are below the non-printing surface. The recesses are filled with ink and the surplus is cleaned off the non-printing area with a blade before the paper contacts the whole surface and lifts the ink from the recesses.
A high-quality printing technique that uses direct contact between an etched copper plate and the paper. This technique is rather expensive because the plate has a relatively high cost. However, it is the best way to print high quality, large volume materials such as brochures and annual reports.
Intaglio printing process employing minute engraved "cells" which carry the ink to the printing surface. Rotogravure employs etched cylinders and web fed stock. Sheet fed gravure, as the name implies, involves individual sheet feeding.
A printing process that employs minute engraved wells. Deeply etched wells carry more ink than a raised surface, hence print darker value shallow wells are used to print values. A doctor blade wipes excess ink from the cylindrical printing surface.
Depositing ink on plastic film or sheeting or product from depressions of a specific depth, pattern and spacing, which have been either mechanically or chemically engraved into a printing cylinder.
A printing process employing minute engraved wells (cells). Generally, deeply etched wells carry more ink than a raised surface (letterpress and flexographic), hence print darker values. Shallow wells print lighter values. A doctor blade wipes excess ink from the cylindrical printing surface. Rotogravure employs etched cylinders and web-fed stock.
