Gravure is capable of transferring more ink to the paper than other printing processes, gravure is noted for its remarkable density range (light to shadow) and hence is a process of choice for fine art and photography reproduction, though not typically as clean an image as that of sheet fed litho or web offset litho. Gravure Inks is also well-suited for printing on a host of other types of substrates, such as foils, plastics, etc. When used on plastic packaging, most gravure presses require the use of fast-drying solvents. Other use for the gravure processes are in wallpapers and laminates for furniture where quality and consistency are desired.
Gravure or Roto or Rotogravure is the process of intaglio printing. In this printing process the image impression is engraved on an image carrier using a rotary printing press. Mostly gravure inks are extensively used in printing magazines. Since it has the major quality to print all types of images as a dots pattern and it makes easy visibility. Enormous gravure presses print mostly on reels of paper instead of sheets of paper. Rotary gravure presses has the capability to print quickly and extensively. For example it can print upto 12 feet narrow labels and even print 4 meter wide rolls.
Rotogravure is a modern printing process for the most part of commercial printing. And it is utilized for the high velocity creation of extensive print magazines. It can print steadily huge number of mail order catalogs and magazines with high quality. Gravure press has saddle stitching as added services for magazine or brochure work. A rotogravure ink is used for printing postcards, corrugated packaging and magazines.
The inking framework for a gravure press is far less difficult than that utilized for offset lithography. The gravure cylinder is somewhat submerged in a vast container of slim, intensely liquid ink. Now the ink is pushed into the fountain pan as much required from the sump. Then the surface of the cylinder filled with the ink due to the rotation of the cylinder on the ink. Finally the excess ink is removed from the surface of the cylinder with the help of slim, flexible blade and pre-wiping devices. This will avoid the inked cells to contact with the substrate. A few gravure inking framework use cloth-covered roller which is moderately submerged but it makes the ink fountain to contact with the surface of the gravure cylinder. Sometimes ink is spread onto the surface of the barrel by a spout.
Usage of Rotogravure Inks
Gravure is widely used for long-run magazine printing, wrappers printing and flexible packaging printing in excess of 1 million copies. Gravure’s major quality shortcoming is that all images, including type and “solids”, are actually printed as dots, and the screen pattern of these dots is readily visible to the naked eye.
