What Is Flexography Printing?

Flexography is a common printing method for high-volume productions, using films, papers, and foils. It uses inks that you can evaporate. One benefit of this type is that you can use it on food products, which allows you to work with various products. In this process, ink is put on the roller, and a blade allows the removal of the extra amount of ink.

This ink comes from the rubber plate, which comes to the letterpress cylinder that holds the ink. Next, the plate that carries the ink allows an image to be transferred to the paper.

Advantages Of Flexography Printing

So, why do we have to do this type of printing? Well, there are multiple reasons, like:

  • It is among the types that work for the vastest range of needs. You can try it for many surfaces, including flat, rough, porous, and non-porous.
  • Also, you can use it with a wide range of ink. Additionally, it works for a vast range of procedures post-process. At the same time, you can dry it easily, and you do not have to spend a lot of ink on this type.
  • At the same time, it offers an eco-friendly solution that makes a huge impact.

Flexography Printing Packaging Pieces Of Equipment

Knowing about flexographic equipment can help you learn many things about this type. So, if you want to use this printing type, you should also understand the basic equipment you should know about.

What is a Print Wheel?

When it comes to this type of printing, you need to know this equipment well. So, you need to know the size of the message you want to print on your product. At the same time, you should figure out the number of times this message will be on your print job. Your wheel’s circumference has a huge impact on the product you get.

The Printer

The printer is an important part of your flexography job and comes in various sizes. You can use them for different material sizes and try using multiple printers simultaneously.

Flexography Printing And Inking Methods

Ink is an important part of your print jobs and can change how things work. Here is what you need to know about these systems:

  • The two-roll inking system allows a rubber roller to pick the ink from the reservoir and then take it to the transfer roll. Then, the ink is applied to the plate, which allows you to print on it.
  • The single-roll system would use a doctor blade that takes the extra ink from the pickup roller. Also, it ensures the printing plate gets the right amount of ink for your print jobs.

Some Other Pieces of Equipment

There are some other pieces of equipment you need to know about when doing a print job in flexography:

  • You should have mounting frames and backup rolls.
  • A pneumatic cylinder lets you decide where printers will come on and off.
  • Also, you should have motor drives to control the printers well and take them to upline speed.
  • Using ink pumps and doctor blade chamber systems will help you get automation in the inking system.

How to Do Flexographic Printing?

In this section, you can read about the process you must follow for flexographic printing. So, here we go:

  • The process starts with preparing what will be printed on your product. So, you should make the artwork in software and keep all the specifications you need to consider for the particular job.
  • In the second step, the substrate materials are rolled inside the machine, ensuring the process becomes automated without any breaks.
  • Then, the substrate roll goes into the printing press. Also, the enclosed chamber inside the press gets ink and fills it. Next, the doctor’s blade chamber determines to remove extra ink.
  • The next step is to ensure the ink goes to the image carrier from the inking system. This process becomes possible with an anilox roller with microscopic cells that allow a layer of ink.
  • Next, the image carrier allows the image to go to the substrate.
  • Your system keeps the best pressure and allows the substrate to get the process between the image carrier and the impression cylinder.
  • Then comes the drying process, where roller-less and plate-less dry your ink.
  • The last step occurs when your substrate gets rolled up and the die-cutting is done. This way, every piece of separate printing gets separated.

This process gets your flexo printing job done, and you need to learn to master and troubleshoot it to perfect your print jobs.
