Key steps in the process
Flexographic printing begins with a pre-press phase, where flexographic plates are created with digital systems such as DuPont Cyrel. These cylinders are then used to transfer precise patterns onto various types of substrates.
- Inking is provided by anilox rollers, which apply a uniform amount of water-based, solvent or UV dyes.
Once printing is complete, finishing touches such as lamination or varnishing add a layer of protection and enhance the visual excellence of the products.
Materials and inks used
Flexographic printing is suitable for various substrates, including paper, cardboard and plastic or metal film. Printing dyes, whether solvent, UV, solvent or water-based, meet the specific needs of the applications, ensuring excellent adhesion and high-end color. This process is recognized for its ability to produce durable and vibrant flexo prints, essential for high-end packaging, meeting customer expectations.

Importance of flexo cylinders
Printing cylinders play a central role in this type of printing. Made of photopolymer, they are designed to offer excellent reproduction of details and a conversion speed adapted to industrial needs. The choice of suitable cylinders guarantees homogeneous flexo printing and consistent results. These accessories are also optimized to reduce the environmental impact thanks to cleaning processes and non-toxic agents, meeting the requirements of global standards for sustainable production.
The advantages of flexographic printing
Flexographic printing is distinguished by characteristics that meet the requirements of modern industries. Its speed and flexibility make it essential for various uses, particularly in the field of packaging.
Versatility of flexo printing media
Flexography easily adapts to a wide range of media, whether cardboard, metal or plastic film. This process is commonly used to produce food packaging or industrial bags. Thanks to the specific dyes, the results are high performance on each type of substrate. This ability to work with different materials makes it a solution adapted to the varied needs of customers in global sectors.
Efficiency and speed of production
Flexographic printing is designed for fast work cycles thanks to its instant-drying dyes and continuous machines. This technology significantly reduces downtime and losses during the activity. The anilox rollers and photopolymer cylinders guarantee precise and consistent printing. The combination of productivity and precision is ideal to meet the needs of users requiring tight deadlines.
Economic and ecological advantages
The printing cylinders (DuPont Cyrel, etc.) are robust and designed for extended use cycles, reducing the costs associated with their replacement. Please use water-based or low-solvent dyes to reduce the environmental and cleaning effect of the process. Advanced cleaning systems, such as those offered by leaders such as DuPont, also limit the use of harmful agents. This sustainable approach meets the expectations of users seeking solutions that combine design and compliance with global environmental standards.
Main uses of flexo printing
Flexographic printing is distinguished by its ability to produce a wide variety of products on various substrates. This process is used in several sectors to meet specific industrial needs.
Packaging
Flexographic printing is essential for food, pharmaceutical and industrial packaging. This process allows the addition of specialized finishes, such as metallic effects, which enhance the visual appearance of the product. The flexibility of flexo printing dyes compared to machines ensures uniform use on substrates such as plastic film or cardboard. This technology provides reliable information that meets the requirements of users who are looking for reliable converting solutions for their high-end packaging.
Labels
Flexography is ideal for adhesive labels, heat-shrinkable compared to other formats. It guarantees a clear flexo print with vibrant color, even on complex surfaces. This process is often used for a mass-market product, particularly in the food and cosmetics sectors. Water-based and solvent-based dyes provide long-lasting results, which are essential for packaging that must withstand environmental constraints.
Other printed products
In addition to packaging, flexographic printing is applied to products such as newspapers and wallpapers. The process is valued for its ability to print complex patterns on a variety of substrates. Modern machines, such as those equipped with DuPont Cyrel cylinders, provide exceptional information and precision while meeting the needs of high-volume production. This makes it an essential solution for applications in diverse and constantly changing markets.
Tips for optimizing flexographic printing
Optimizing flexographic printing requires careful planning and careful selection of materials and equipment. These practices ensure consistent results while meeting specific customer needs.
Choosing the right systems and dyes
The choice of dyes depends on the type of substrate used, whether it is paper, plastic films or cardboard. Water-based, UV or solvent-based inks adapt to different types of applications and guarantee good adhesion. Indeed, please use machines adapted to the chosen dyes to maintain a consistent design. Investing in systems such as those offered by DuPont can improve the precision and visual impact of the printed product.
Collaborate with an expert team
Working with a team specialized in flexography can transform the management of your printing projects. These experts know the subtleties of printing machines and cylinders (DuPont Cyrel, etc.), which makes it easier to choose the right solutions. Their experience also allows them to optimize the use of dyes in relation to the chosen materials. This also meets user expectations while respecting global standards. Close collaboration improves the quality and consistency of finished products.
Improve production management
Download specialized guides and use dedicated tools to optimize the selection of your flexographic machines and products. These resources provide valuable information on choosing the right dyes and cylinders for each application. They also help organize work smoothly to meet deadlines and reduce waste. Proactive management promotes faster activity cycles while maintaining a high level of performance in final reports.
