When it comes to package a product, printing plays a crucial role. These days more and more printing companies are opting for flexography. It has become a common printing method. Companies prefer this method because it ensures high quality printing. Various materials can be printed with the help of this technology. It can be used on corrugated cardboard boxes, gable boxes, cartons, disposable containers, paper sacks, wrappers and labels of food items.
Why Flexography has become so popular?
One of the reasons for which this method has become popular is definitely that it can be used on different packaging materials. However, the major reason behind its popularity is that this method is very simple. It is absolutely easy to carry out printing on various materials.
Another reason for which companies prefer this technology is that it is adaptable to water-based ink easily. Using water based ink decreases the emission on VOC (volatile organic compound) which is highly pollutant. Flexography can be considered to be a green orienting technology.
Colors used in Flexography
Like other printing methods such as Gravure and Lithographic, the four basic colors used in Flexography include black, cyan, magenta and yellow. These colors are mixed to create different shades on the surface of the custom printing boxes. These inks dry quickly due to their low viscosity.
How flexography is carried out?
This printing method can be divided into four segments including
- Image preparation
- Plate making
Image Preparation: Images are captured or produced and then assembled to create a single image that will be printed on the surface of the printing material.
Plate Making: The Flexographic plates are created. Rubber, plastic or special type of polymer is used to create the plates. The plates are then attached to a roller so that ink can be applied. The images come in contact with the ink.
Printing: The next step is printing which is done in either of the 5 methods including in-line, newspaper unit, stack type, commercial publication Fflexographic presses and central impression cylinder.
Finishing: The printing material undergoes different procedures such as cutting, coating, folding to finish the packing of custom printed gable boxes or cartons or disposable containers and many more.
