Flexographic Printing: A Complete Overview
Flexographic printing, often referred to as “flexo printing,” is a versatile method used for printing on various flexible materials, including paper, plastic, cellophane, and metallic film1. In this article, we’ll explore the process, applications, and benefits of flexography.Get more news about

The Flexographic Printing Process
Pre-press Preparation:
The pre-press process is crucial for flexographic printing. Accurate artwork preparation and platemaking are essential to avoid wasted ink and materials.
Flexible printing plates, typically made of rubber or photopolymer, are mounted onto a cylinder.
The substrate passes through the press, and ink is transferred from the anilox roller (which controls ink flow) to the printing plate.
Printing Stations:
Each flexographic press has multiple printing stations, depending on the number of colors needed.
For each printing station, a roll of material passes through multiple flexible rotary plates, with each plate used for a single printed color.
The plates derive their color from specialized rollers that transfer ink onto the plates.
The plate cylinder and impression cylinder work together to apply pressure, transferring ink from the plate to the substrate.
Substrate Variety:
Flexography can print on a wide range of substrates, including coated or uncoated paper, corrugated cardboard, metal, and plastic film.
Applications of Flexography
Packaging Industry:
Originally used primarily for food packaging, flexographic printing has evolved to serve many other applications.
Approximately 60% of the packaging industry utilizes flexography in some way.
Industrial Printing:
Simple and economical rotary flexo printers use printing plates on a drum to continuously print logos and messages on flat products during production.
In summary, flexographic printing offers versatility, high-quality results, and the ability to print on diverse materials. Whether for packaging, labels, or industrial applications, flexo printing remains a valuable choice in the world of printing technology.
