The nature and demands of the printing process and the utilization of the printed product determine the essential properties required of flexo products. Measuring the substantial properties of inks/coatings and understanding how these are affected by the choice of constitutants is a important part of the technology. Flexographic printing products 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 Four main variants that can be used in flexography:
- electron beam (EB) curing
- ultraviolet (UV) curing
What is it used for?
Flexo has an advantage over lithography in that it can use a wider range of inks, and is good at printing on a variety of different materials like: foil, brown paper, film, and synthetic paper. Typical products printed using flexography include: brown corrugated boxes, flexible packaging, retail bags, shopping bags, food bags, hygiene bags, beverage cartons, flexible plastics, self-adhesive labels, disposable cups, laminates, and even envelopes.
What equipment do you use?
Many companies make these presses and a few of them are: Mark Andy, NilPeter, Rotatek, LohiaCorp, Domino, Heidelberg, Hemingstone, Bobst, and many many more!
These presses utilize 1-8 colors typically and are highly customizable. All or most of these presses have the following: fountain roller, doctor blade, anilox roller, plate cyliner, flexo plate, and an impression cylinder.
