Rotogravure Printing Machine

We are an eminent Rotogravure Printing Machine Manufacturer, Exporter and Supplier in India. Rotogravure is a type of intaglio printing process; that is, it involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, it uses a rotary printing press. Once a staple of newspaper photo features, the rotogravure process is still used for commercial printing of magazines, postcards, and corrugated (cardboard) product packaging.

Details :

  • The first step of gravure is to create the cylinder with the engraved images that need to be printed: the engraving process will create on the cylinder surface the cells that will contain the ink in order to transfer it to the paper.
  • Since the amount of ink contained in the cells correspond to different color intensities on the paper, the dimensions of the cells must be carefully set: deeper cells will produce more intensive colors whereas less deep cells will produce less intensive ones.
  • There are three methods of photoengraving that have been used for engraving of gravure cylinders, where the cell open size or the depth of cells can be uniform or variable - gravure cylinders of Rotogravure Printing Machine are usually made of steel and plated with copper and a light-sensitive coating. Previously machined to remove imperfections in the copper, most cylinders are now laser engraved.
  • In the past, they were either engraved using a diamond stylus or chemically etched using ferric chloride, which creates pollution. If the cylinder was chemically etched, a resist (in the form of a negative image) was transferred to the cylinder before etching. The resist protects the non-image areas of the cylinder from the etchant. After etching, the resist was stripped off. The operation of Rotogravure Printing Machine is analogous to the manufacture of printed circuit boards.
  • Following engraving, the cylinder is proofed and tested, reworked if necessary, and then chrome plated. a rotogravure printing press has one printing unit for each color, typically CMYK or cyan, magenta, yellow and key (printing terminology for black), but the number of units varies depending on what colors are required to produce the final image. There are five basic components in each color unit: an engraved cylinder whose circumference can differ according to the layout of the job; an ink fountain; a doctor blade; an impression roller; a dryer.
