It is a relief printing process it utilizes an engraved printing plate. It moves ink on a substrate, Main elements of rotogravure plate wrapped around a tube, doctor blade, belief cylinder, substrate rolls right through off into a drying device.

In packaging this procedure is utilized to print items such as plastic pictures and to make this procedure unique is that engraved printing plate, it is etched mainly to generate little cells. Which maintain the ink and based upon the thickness and the dimensions of their mobile it retains less or more ink you get longer unique detail or much more intense colors.

Rotogravure Printing Procedure

The rotogravure process is an immediate transfer way of printing on wood-pulp fiber based, artificial, or laminated substrates, for example, Movies like polyester, OPP, nylon, and PE.

The modern-day rotogravure printing press utilizes a printing cylinder that has been laser engraved with other cells capable of keeping ink, the dimensions and pattern of that reflect the primary image. These cells are made to move their ink directly onto the substrate with a mixture of stress and capillary activity, so generating the printed picture.

The procedure, also commonly referred to as gravure printing, is employed in the production of food and non-food packaging, in addition to tags, wall coverings, transfer printing, also contains an assortment of additional applications in the security printing, industrial, and tobacco sections of a business.

Rotogravure Printing Presses

The design of a gravure printing media follows an in-line arrangement in which the necessary variety of printing units is set up over a horizontal plane. At a conventional gravure printing press, every group consists of these are following

Printing Cylinder: A Sleek tubular sleeve or Complete cylinder, made from steel, aluminum, Vinyl, or composite material, which Can Be engraved with the Picture to be printed.

Doctor Blade: The System that removes ink in the non-engraved Parts of the printing cylinder and also removes excess ink in the engraved sections.

Impression Roller: a rubber coated sleeve that’s mounted onto a steel mandrel. Its primary purpose is to press on the substrate contrary to the printing cylinder.

Inking System: Comprising an ink pen, ink holding tank, and Also ink pump with Return and Supply ink pipes.

Drying System: comprising a room that dries the ink when it’s about the substrate and before it reached another printing device. Drier abilities are determined based upon the required printing rate, ink sort (solvent or water-based), and ink put down the volume.


The rotogravure printing method has become the most popular printing process employed in flexible-packaging production, due to its ability to publish on thin films like polyester, OPP, nylon, and PE, which come in a vast assortment of thicknesses, generally 10 to 30 micrometers.

Other valued features include:

1-printing cylinders which may continue through large-volume runs with no image degrading.

2-Superior Excellent picture reproduction.

3-Low per-unit prices are running high volume manufacturing.


Shortcomings of the gravure printing process include:

1-Large startup prices: hundreds of thousands of copies required to make it rewarding

2- Rasterized texts and lines

3-Long lead time for cylinder preparation, which can be offsite as the methods utilized are so technical


Through assessing about the optical print quality effect by the viscosities of gravure ink, the decisions are after: – The change curve of ink density differs for different viscosity values along with the frequencies does not necessarily increase with viscosity raising (more moments in unit quantity), but it’s better with higher density value. The value of density does not significantly increase with viscosity rising, but it may be diminished after reaching a saturation point. Twenty-five minutes is Best viscosity to be chosen to get black ink. – Different viscosity worth of up ink 16 minutes to 30 seconds, the comparison properties are not better with ink viscosity bigger or even smaller. However, from 22-25 moments, a comparison is best for ink viscosity. – As a goal analysis, the raising of ink viscosity caused more subdued of printing look, and cause mottling issue. Dots of the high and low – viscosity trials exhibited problems like dispersing, missing dots, and doughnuts. The Very Best scatter structure was observed in 22 next to 25 moments for black color.
