Flexography is a form of relief printing that uses flexible photopolymer plates and water-based inks to create sharp, detailed images on a wide variety of substrates. These presses are favored for their speed and versatility, which makes them suitable for a range of applications from labels and packaging to newspapers and magazines. In this overview, we will explore the advantages of flexographic presses, how they work, and their applications in the digital printing industry.


printing is a form of relief printing used to produce labels, packaging, and other products.

This type of printing uses flexible plates that are wrapped around cylinders, allowing for a broad range of colors and designs. Flexography is often used in printing on plastic, paper, cardboard, or other materials. Flexography differs from other types of printing such as offset printing, digital printing, and silk screen printing in that it uses liquid inks that are applied directly to the substrate via a flexible relief plate. Offset printing uses an intermediate medium such as a rubber blanket to transfer the image from the plate to the substrate.

Digital printing relies on inkjet technology to apply the image directly to the substrate. Silk screen printing uses a stencil to press ink through a mesh onto the substrate. The advantages of flexography include its cost effectiveness, ability to print on a wide variety of materials, fast turnaround times, and ability to print on irregular surfaces. The disadvantages include its lack of accuracy when reproducing fine detail, limited color gamut, and the need for frequent plate changes.

There are several types of flexographic presses available including letterpresses, rotary presses, and web presses. Letterpresses use a flat plate cylinder with a raised image that is then transferred to the substrate. Rotary presses use a cylindrical plate that is wrapped around an impression cylinder and then inked with a series of rollers before transferring the image to the substrate. Web presses are continuous presses that can print large volumes of product quickly and efficiently. The components of a flexographic press include the plate cylinders, anilox rollers, inking systems, impression cylinders, doctor blades, drive systems, and drying systems.

The plate cylinder holds the flexographic plates which have an image area that has been raised off the surface and a non-image area that remains flat. The anilox rollers transfer the ink from the ink pan to the plate cylinder. The inking system applies ink to the plate cylinder, while the impression cylinder transfers the image onto the substrate. The doctor blades wipe any excess ink from the plate cylinders and impression cylinders, while the drive systems control the speed at which the press operates.

Finally, the drying system ensures that the ink dries quickly before it reaches its destination. The setup of a flexographic press begins with loading the plate cylinders into place. Once these are loaded and locked in position, they are aligned with each other and with the impression cylinder. The next step is to install the inking system which consists of two rollers that apply ink to the plate cylinder. Lastly, adjustments are made to ensure that there is even pressure between all three cylinders and that they are all in perfect alignment with each other. Once setup is complete and all three cylinders are aligned properly, it is time to start printing.

The press begins by loading the substrate onto a conveyor belt which will carry it through all three cylinders. As it passes through each cylinder it picks up more color until it is complete and ready for drying. Flexography can be used for printing labels, packaging materials, paper products, plastic products, cardboard products, and much more. Examples of products printed using flexography include beverage labels, cartons, shrink wrap labels, folding carton boxes, flexible packaging materials, and much more. When choosing a flexographic press for your needs there are several considerations to keep in mind such as cost effectiveness, speed of production, and types of substrates that can be printed on. Additionally, proper maintenance and training is essential for ensuring optimal performance from your press.

Choosing the Right Flexographic Press

When selecting a flexographic press for your needs, there are a few important considerations to keep in mind.

First, consider the size of the press and its capabilities. If you need to print large runs of labels or packaging, you may need a larger press with more advanced features. Additionally, think about the materials and colors you will be printing on, as well as the type of ink you need and the type of printing plate you will use. The cost of the flexographic press should also be taken into account. You should also consider the level of automation of the press.

Automation can help to streamline production and reduce costs, but if you only need to print small runs of labels or packaging then manual presses may be more appropriate. Finally, consider the training and support that comes with the press. Investing in a quality flexographic press is important, but having access to experienced technicians who can provide technical support and training is equally important.

Advantages and Disadvantages of Flexography

Flexography is a form of printing that has become increasingly popular in recent years due to its cost-effectiveness, speed, quality, durability, and environmental friendliness. While the advantages of flexography are numerous, there are some potential drawbacks as well.

Cost-effectivenessFlexography is often more cost-effective than other printing processes, especially when printing on large quantities of materials. The plates used in flexography are relatively inexpensive and can be used for multiple print runs without requiring additional costs for new plates. Additionally, the process is fast, which can help reduce costs associated with labor.


Flexography is a very fast printing process, making it ideal for large print jobs. The process can be completed in a fraction of the time it takes to complete other forms of printing, such as offset or digital printing.


Flexography produces very high-quality prints with excellent detail and definition.

This makes it an ideal choice for printing labels, packaging, and other products that require high-resolution images.

Environmental Friendliness

Flexography is an environmentally friendly printing process due to the fact that it does not require the use of solvents or other hazardous materials. This makes it a safe option for companies that are looking to reduce their environmental impact.

How Does a Flexographic Press Work?

Flexographic printing is a versatile form of printing that uses flexible plates on cylinders to produce high-quality prints in a variety of colors and designs. To understand how a flexographic press works, it is important to understand the various components involved in the process.

The first step in setting up a flexographic press is to mount the rubber plate on the cylinder. This is done by using a solvent to attach the plate to the cylinder. Once the plate is in place, it is then clamped onto the cylinder. After this, the ink is mixed and loaded into a fountain, which is attached to the press.

Next, the press needs to be set up to receive the substrate material. Substrate materials such as paper, plastic film, or foil are placed between two rollers and passed through the press. This ensures that the substrate material is fed into the printing process in an even manner. Once the substrate material is ready, it is then fed through the press and comes in contact with the rubber plate.

As it passes over the plate, it picks up the ink and transfers it onto the substrate material. The process of transferring the ink onto the substrate material is known as flexography. Once all of these steps are complete, the substrate material is then passed through a drying tunnel, which removes any excess ink and ensures that the final product is clean and dry. After this, it is then ready to be cut and packaged for shipping.

Components of a Flexographic Press

Flexographic printing presses are composed of several components.

The most important are the plate cylinders, anilox rollers, inking systems, and impression cylinders. Plate cylinders are the main component of a flexographic press. They are made from metal or polymer, and carry the image to be printed. Anilox rollers are also essential for flexography.

They are used to transfer the correct amount of ink onto the plate cylinder. The inking system is responsible for distributing ink onto the plate cylinder evenly. Finally, the impression cylinder presses the substrate against the plate cylinder, allowing for the transfer of ink onto the substrate. In addition to these four main components, flexographic presses also contain other parts such as doctor blades, impression systems, register systems, and drying systems. Doctor blades are used to keep excess ink off the anilox roller and ensure it transfers only a specific amount of ink onto the plate cylinder.

Impression systems are responsible for maintaining pressure between the plate cylinder and the impression cylinder so that ink is transferred correctly. Register systems help ensure that images are printed in their exact positions on the substrate. Finally, drying systems are used to ensure that the printed image is dry before it is moved off the press. Flexographic presses have come a long way since they were first introduced. Today’s flexographic presses have advanced components and technologies that allow for precise printing and higher quality images.

With a better understanding of these components and how they work together, you can make sure your flexographic press is running optimally.
