What Is Flexographic Printer?
A flexographic printer is a type of printing press that utilizes flexible relief plates to transfer ink onto various substrates. It is commonly used in large-scale printing operations, delivering high-quality and high-speed printing results. Flexographic printers offer excellent versatility, allowing precise printing on a range of materials such as paper, plastic, cardboard, and flexible packaging.
Flexography is known for providing quality results and its efficiency in speed. The popularity of flexo printing continues to grow, despite widespread digitisation in many printing sectors. Here are main advantages of flexography.
High Quality Paint
Flexography achieves a consistently high level of print quality across a wide range of materials/substrates without the need of special coatings, as it reduces the overall cost per unit. This is a significant advantage over other print solutions which may have a very narrow band of compatible substrates.
High Speed Production
Flexographic printers are designed for high-speed production, enabling rapid printing of large quantities. This makes them a preferred choice for time-sensitive projects, meeting demanding deadlines without compromising print quality.
Versatile Paint Process
Flexographic printing can be applied to a wide range of industries, including textile printing, packaging printing, label printing and more. The versatility of the machines means that presses can be adapted to accommodate different types of order, giving print businesses the ability to diversify their market appeal and remain competitive.
Economic For Medium & High Volume Production
Despite great advances in digital printing, digital is still expensive and comparatively slow for medium and high volume print runs. For the many clients who still require medium to large volume print runs, especially in the label business, flexography wins hands down and can often compete with Digital on short runs too.
One-Off Cost For Plates
Once a plate is made, it can be used an indefinite number of times with no additional costs. This means that the larger the print run, the lower your cost per unit. If looked after correctly, Flexo plates can be reused many times, so that repeat orders can be printed with very few overheads. This often compares favourably with the design and setup time required for digital printing, especially on labour intensive short volume print runs.
In-Line Converting Flexibility
Cycle time is drastically reduced by the in-line converting capacity native to many modern flexographic printers. This means that most print runs can be completed in a single pass. Flexographic printers can integrate many other kinds of in-line processes too, including silk screen, hot foil, cold foil, digital print, variable data print, lamination, booklet insertion, RFID insertion, multi-layer printing, and reverse side print. It is also possible to apply primers, coatings, adhesives and varnishes in-line, cutting overall finishing time.
Possible to Use Different Types of Inks & Drying Systems
Inks and drying systems have developed in complexity and efficiency alongside flexographic print technology itself. A modern flexographic printer can use a variety of water-based or solvent based inks. Efficient drying mechanisms – whether using air heaters, IR or UV Driers – can increase web speed, reduce overall energy consumption and decrease ink usage. Printers have access to a potentially limitless number of colours through easy mixing of modern inks. Precise and repeatable colour formulas can be created that retain faithful consistency even when used on multiple substrates, e.g. company brand colours used on labels, food packaging and textiles.
Easy to Use and Maintain
One of the arguments in favour of digital printing is the supposedly cumbersome setup time required by flexographic printers. While this may have been the case in the old typesetting days, modern flexographic printers actually have very short set up and job changeover time, enhanced by the latest Servo drive systems. Furthermore, a flexographic printer will give you a long production lifespan – and an impressive ROI – with relatively few maintenance requirements, so long as the unit is serviced regularly.
