Like engraving, gravure is a form of intaglio printing that produces fine, detailed images. Gravure printing has usually been the chosen process most suitable for printing fine tones with a sharp dot formation giving a high quality result and best suited to the long run markets. There are four basic means of engraving the image into a gravure cylinder: Diffusion-Etch Process. It is an intaglio printing process where the image is engraved onto the surface of an image carrier below its nominal surface. Gravure presses run at high production speeds: 3000-3300 feet per minute. Electromechanical engraving devices take much longer than chemical processes; on a 40-inch wide cylinder with a 30-inch circumference, there are over 25 million cells. The direct-transfer process is also quicker than the diffusion-etch process, taking only about 4:10 minutes to etch a cylinder. A solvent is used to wash away the unexposed resist, and the photopolymeric resist produces cells that print with smoother edges than cells etched by electromechanical engraving. The popularity of the Sunday rotogravure section, which was filled with printed photographs, increased the use of gravure. The ink is transferred to a substrate (paper, plastic, film, and more) using a rotary press. We also make it possible to produce extremely complex and high-resolution applications, as required in security printing, via special gravure cylinder that are oriented to the particular requirements.

Rotogravure (or gravure for short) is a type of intaglio printing process, which involves engraving the image onto an image carrier. Gravure, unlike most other printing processes, prints from depressed, ink-filled cells produced on the surface of a copper-plated cylinder. Gravure printing cylinder for printing machine. A gravure cylinder comprises a (typically) steel cylinder base, or an underlying metal structure that supports the engraved image-carrying layer. As in the diffusion-etch process, the exposed (non-image) areas become hard, while the unexposed (image) areas remain soft. Also called the Single-Positive System, the direct transfer process is, like the diffusion-etch process, a chemical etching process. Gravure Gravure Also known as rotogravure, this is a technique in which an image is engraved into a printing cylinder. Gravure5. Also called conventional gravure engraving, diffusion-etch is the oldest method of gravure cylinder engraving. Copper polishing machine 4. Each printing process has its strengths. 07-Jan-2019. Building on earlier printing methods, modern gravure began in the late 19th century, and became widespread in the early 20th century. The screen is used to "convert" the solid image into many tiny cells (similar to making a halftone from a continuous-tone photograph, for example), which are small squares oriented at a 45º angle to the direction of web travel through the press (diamonds, basically). First came chemical etch, followed by electro-mechanical (diamond cutting) and then laser etching. A roto-gravure printing base cylinder is made by providing a cylindrical body (1), for example of steel, and applying thereover a cover layer (2) by thermal spraying, for example plasma-spraying, or arc-spraying.
