- Flexo Label Printing Machine is for Self-adhesive paper is relatively thick, generally as thick as two sheets of 150g/m2 coated paper. It is composed of two layers: coated paper, aluminum foil, colored polyester film printing layer and wax paper layer.
- The paper used for self-adhesive printing is generally high-grade coated paper, gold card, silver cardboard, and colored polyester film. The surface of the paper is smooth and clean.
- The self-adhesive paper has low ink absorption. It is composed of base paper and top paper. It is easy to separate and affect the printing plate. The printing speed should be slower.
- When printing a large area of images on a full page, it is easy to get dirty on the back.
The Flexo Label Printing Machine is essential for efficient label production.
The Flexo Label Printing Machine excels in producing high-quality labels.
Using a Flexo Label Printing Machine ensures optimal ink distribution.
Flexo Label Printing Machines are designed to minimize mess during operation.
Self-adhesive label printing, also called self-adhesive printing and trademark printing, involves using a Flexo Label Printing Machine to print labels onto self-adhesive materials. The printed products can be easily peeled off and pasted onto goods or products. This method is essential for marking packaging efficiently.
Printing method one: embossed printing
Self-adhesive labels are printed using letterpress printing. The printing plate is a photosensitive resin letterpress plate. The printed labels have the advantage of full ink color. However, the grades of letterpress printing equipment vary greatly. Some are still using circular flattening letterpress printing machines, and some are using ordinary letterpress printing machines. Some rotary letterpress machines have adopted professional inclined-back, satellite or unit-type self-adhesive label printing machines, so they cannot be generalized during the transformation.
The Flexo Label Printing Machine is particularly well-suited for high-speed production lines.
With a Flexo Label Printing Machine, professionals can achieve precise color matching.
The Flexo Label Printing Machine offers versatility for various printing substrates.
Understanding the capabilities of the Flexo Label Printing Machine is crucial for modern printing businesses.
The adoption of the Flexo Label Printing Machine has revolutionized label production.
Professional self-adhesive printing machines primarily focus on letterpress printing and have the ability to print film labels. However, they require contacting the supplier to replace certain components. This includes adding a tension control system managed by a servo motor and a film surface treatment unit. Additionally, some high-end machines can incorporate precision registration systems. It’s also essential to adjust the UV light source power appropriately.
Utilizing a Flexo Label Printing Machine can significantly reduce production costs.
Many print houses are investing in Flexo Label Printing Machines for their efficiency.
Flexo Label Printing Machines are designed to accommodate a wide range of label formats.
The choice of a Flexo Label Printing Machine can enhance production flexibility.
For enterprises that use circular flat letterpress printing machines to print self-adhesive labels, if they print film labels, they can replace the photosensitive resin plate with a highly elastic flexographic plate, use water-based inks or UV inks suitable for flexographic plates, and change the properties of the ink. Adapt to substrate changes.
Understanding the Flexo Label Printing Machine
Printing method two: offset printing
Offset printing serves as the main method for label printing factories in my country for paper self-adhesives. This printing method is characterized by fine graphics and depth of layers, making it suitable for mass production. The equipment can be multi-purpose, aligning well with the characteristics of the Chinese label market. However, sheet-fed offset printing is not ideal for printing films with non-absorbent surfaces. Film labels typically require roll-to-roll printing and use volatile drying inks. While offset printing can handle thicker plastic materials, like in-mold labels and tags, the machine must be equipped with a UV curing device, which entails significant costs.
Printing method three: flexo printing
At present, the quality of flexographic printing is no less than that of offset printing, and even has its own unique features. The advantages of this printing process are simple machine structure and low cost. The printing quality is comparable to offset printing and gravure printing, and has the advantage of thicker ink layer than offset printing products. Flexo printing uses water-based ink and UV ink, which does not pollute the environment.
Flexographic printing offers a quality comparable to that of offset printing and boasts unique features. Its advantages include a simple machine structure and lower costs. The printing quality rivals that of offset and gravure printing, with a thicker ink layer than offset products. Flexo printing employs water-based and UV inks, contributing to environmental sustainability.
Printing method four: gravure printing
Gravure printing utilizes a short ink path ink supply system and is web-fed, showcasing a high degree of automation. It employs solvent-based inks that dry quickly, making it the preferred choice for film printing. Gravure printing machines typically operate at higher speeds and often include a roller die-cutting device, allowing for die-cutting and creasing. This method is suitable for printing various labels; however, due to lengthy plate-making cycles and high costs, gravure is best suited for large-volume label production.
Printing method five: screen printing
Screen printing is the most adaptable printing method for various substrates. Many screen printing factories currently utilize affordable equipment to handle the printing of self-adhesive labels and film labels.
