If you are related to the printing industry or own a business that needs packaging for its products, you've most probably heard the word “flexography," even if you don’t know its meaning.
Flexography is a type of printing that has changed the whole printing and packaging industry. It is popular because of the speed, efficiency, and versatility that it offers.
Flexographic printing has become the center point of the packaging industry as it is used in several sectors, such as the food, beverage, and pharmaceutical industries. Great results can be achieved on numerous materials like plastic, paper, and metals.
Is it a good choice for your business? Let's find the truth with this blog as it explores every aspect of flexography, including its benefits, step-by-step process, and applications.
Flexography is the new version of the traditional letterpress technique. It uses raised image plates that are made of rubber or photopolymers to apply quick-drying ink onto the base.
This printing process is designed to be used on different types of materials, including uneven and flexible. It always provides consistent results.
Due to this, it is the first choice for industries that require mass production, such as food packaging, label printing, and shipping containers.
Flexography is highly versatile, which is why it is widely used in the market. Here are some examples of flexography printing:
Attractive designs are printed on pouches for snacks and beverages with this type of printing.
It is used to produce vibrant labels for jars and bottles for different industries.
Using flexography, patterns, and designs are printed consistently on a large scale.
Flexography relies on specialized machines and plates to deliver consistent results. Let’s discuss the different presses and plates used in this process.
Modern flexographic printing presses are categorized into three main types. These are described below:
Printing units are stacked vertically into this kind of press. It is suitable for flexible materials.
In the central impression press, the color registration is very precise, as it uses a single impression cylinder.
Print units are arranged horizontally in this type of press. It is used with rigid substrates.
Flexographic plates are made from durable photopolymers. These are designed to be operated at high speed to provide consistent results. These plates are reusable, which makes them cost-effective.
To truly understand the value of flexography, let's take a closer look at each step of this process.
Flexographic printing involves different stages to ensure precision and efficiency. The six steps of this printing process are explained below:
The process begins with designing the plate. It is the heart of flexographic printing. Photopolymer or rubber plates are put under UV light to create raised areas. These plates are then washed and dried for future use.
Flexography uses inks that are based on water and solvents. These can also be cured by UV light. The viscosity of the ink is carefully adjusted for smoother application. These are selected as per requirements.
A cylindrical roll engraved with microscopic cells is used in flexographic printing to transfer ink to a printing plate. It collects a certain amount of ink from the reservoir and transfers it to the printing plate.
The substrate passes through the printing press and the inked plate that is mounted on a cylinder makes direct contact with it. The flexible nature of the plate ensures even ink distribution on uneven surfaces, as well.
After printing, the substrate goes through drying units. The heat helps the ink to cure quickly. If needed, additional steps are carried out to enhance the look and durability. Such as lamination or varnish.
The final product is thoroughly inspected to ensure quality and consistency. Any issues are addressed before packaging and delivery.
Although the process is simple, understanding its advantages and disadvantages will provide a clearer picture of its popularity.
Flexography has revolutionized the printing and packaging industry with versatility and efficiency. However, It comes with both strengths and limitations. Let’s explore the pros and cons of this printing type to find its suitability for your business.
Flexographic printing is used in many industries due to the perks it offers. Some of them are described below:
It works on different types of materials, such as paper, cardboard, plastic, foil, and more.
This printing process is Ideal for high-volume printing as it has minimum downtime.
The setup costs are spread over large production runs. This makes it economical.
Additional operations like cutting and laminating can be done during printing. This makes the overall process convenient.
It is environmentally friendly due to the use of water-based inks and a lower amount of waste.
Apart from offering many advantages, there are also some drawbacks to flexography. These are:
Plate creation is expensive. Due to this reason, this process is less suitable for short runs.
This kind of printing is great for bold designs, but it struggles with gradients and complex designs.
Plates degrade over time. That’s why they need to be replaced to maintain quality.
Wondering if flexo printing is the best or offset. Let’s compare the key differences to get a better understanding.
Although both these printing methods appear the same, they have many differences. These are discussed below:
| Feature | Flexography | Offset Printing |
| Substrates |
Works on porous as well as non-porous materials, such as cardboard and plastic. |
Mostly used on flat and smooth surfaces like paper. |
| Production Speed | It has a faster setup and high speed for large-volume production. | It has a relatively slower setup but it is suitable for small-batch runs. |
| Print Quality | This is good for bold designs but limited in color gradients. | This is superior for detailed and color-accurate images. |
| Cost Efficiency | Economical for longer runs due to lower costs per unit. | Expensive for short runs due to the complicated setup. |
| Applications | Ideal for packaging, labels, and flexible materials. |
Best for brochures, magazines, and high-end printing jobs. |
This comparison clearly shows that flexo printing is the best for massive and high–speed production. Let’s discuss some practical applications of flexography used in the market.
Flexography offers versatility, which is why it is the ideal choice among different industries. Its adaptability with numerous materials and high-quality prints makes it perfect for the following applications:
