Flexographic printing is a popular method for printing large orders of custom labels at rapid speeds
Flexo label printing is a popular method of printing labels that are used on various products in different industries, including food and beverage, pharmaceutical, cosmetic, and personal care. This method of printing is ideal for producing high-quality, durable labels that can withstand various environmental conditions. In this article, we will explore the different aspects of flexo label printing, including the process, materials, advantages, and applications.
What is Flexo Label Printing?
Flexo label printing is a printing process that utilizes flexible printing plates made of rubber or photopolymer materials. The plates are mounted on a cylinder, which rotates and transfers ink onto the substrate (the material to be printed on). The ink is transferred through a series of rollers, each with a specific function, such as ink metering, impression, and transfer.
The flexo printing process allows for a wide range of colors and high-quality printing, with the ability to print on a variety of substrates, including paper, plastic, and metallic materials. It is also possible to add finishing touches to the label, such as embossing, varnishing, and laminating.

Materials Used in Flexo Label Printing
Flexo label printing utilizes various materials, including inks, substrates, and printing plates.
Inks:
Flexo inks are formulated with special properties to adhere to a variety of substrates and dry quickly. The inks are made of four components: pigments, binders, solvents, and additives. Pigments provide the color, binders hold the pigments together, solvents carry the ink to the substrate, and additives improve the ink’s properties, such as viscosity and drying time.
Substrates:
Flexo label printing can be done on a variety of substrates, including paper, plastic, and metallic materials. The choice of substrate depends on the application and the required durability of the label. For example, food and beverage labels must be able to withstand moisture, while pharmaceutical labels must be resistant to chemicals.
Printing Plates:
Flexo printing plates can be made of rubber or photopolymer materials. Rubber plates are more traditional and are made by carving out the design on a rubber material. Photopolymer plates are created by exposing a light-sensitive polymer material to UV light through a film negative. The exposed areas harden, while the unexposed areas are washed away, leaving the design on the plate.
