Offset, the perfect technique for products with a high rotation of designs
The offset printing system is powerful and versatile. With our new COMEXI OFFSET CI8 printer we have become the first company in Spain to offer this technique. Our hybrid printing combines offset and flexography and has a flexographic-printing body and a central drum system that ensures more opaque colours and incredible definition. Perfect for short and medium runs, 3,000m2 plus, of products with a high design rotation.
How does offset printing work?
Offset printing is a system derived from lithography, which is indirect printing. The graphic information is broken down into percentages that are lasered onto a plate. The ink is then transferred to the printing surface with a roller, resulting in the desired design.
The offset technique is characterised by its speed in the production phase. Its EB (Electrom Beam) inks do not contain solvents, dry quickly and are very resistent.
Offset provides high quality in relation to the chosen material (paper or plastic film), well-defined typography, sharp dots and clean stochastic screen, and is comparable to rotogravure in terms of visual quality.
Which markets use offset printing?
As we have seen, offset printing is recommended for short to medium runs from 3,000m2 upwards approximately, and it can be applied to different materials, such as OPP, PET and paper-based laminates.
