Labeling | Holoflex Limited

Label is a piece of paper, polymer or other material affixed to a container or article, on which is printed a legend, information concerning the product, addresses, etc. A label may also be printed directly on the container or article.

Flexographic Printing Technology
At Holoflex Limited we have complete in-house production facility for label printing which uses the Flexographic Printing Technology. Flexography (often abbreviated to flexo) is a form of printing process which utilizes a flexible relief plate. It is essentially a modern version of letterpress which can be used for printing on almost any type of substrate, including plastic, metallic films, cellophane, and paper. It is widely used for printing on the non-porous substrates required for various types of food packaging, product labels, tags etc. The Flexographic Printing Technology involves the following processes:
Plaemaking
Mounting
Printing

Flexographic Printing Ink Technology
Formulating the right ink for the right substrate and application goes a long way in Flexographic Printing Ink Technology. Formulation of flexographic inks requires a detailed knowledge of the physical and chemical properties of the raw materials composing the inks, and how these ingredients affect or react with each other as well as with the environment. Flexographic printing inks are primarily formulated to remain compatible with the wide variety of substrates used in the process. Each formulation component individually fulfills a special function and the proportion and composition will vary according to the substrate.

There are five types of inks that can be used in flexography: Solvent-based inks
Water-based inks
Electron beam (EB) curing inks
Ultraviolet (UV) curing inks
Two-part chemically-curing inks

Ink Control Technology
The ink is controlled in the flexographic printing process by the inking unit. The inking unit can be either of the below:

Fountain Roll System
The fountain roll system is a simple old system yet if there is too much or too little ink this system would likely not control in a good way.

Doctor Blade System
The doctor blade inside the anilox roller uses cell geometry and distribution. These blades insure that the cells are filled with enough ink.
At Holoflex Limited we use the doctor blade system on our flexographic unit to achieve superior print quality.
