Advantages and Features of Flexographic Printing Machines

Flexographic printing machines use fluid inks with strong fluidity. The ink is transferred to the graphic part of the printing plate and inked by the ink fountain roller and anilox roller. Then the printing pressure is applied by the pressure roller to transfer the ink on the printing plate to the substrate, and finally the printing process is completed by the dry surface.

The flexographic printing press is composed of a line connected flexographic printing press and 4-8 mutually independent printing units, which are arranged horizontally and driven by a common power shaft. The unit flexographic press supports only one printing unit for each pair of plates, so the unit flexographic press can be designed to accommodate different drum heads.

    The main advantages of flexographic printing machines are:

  1. For web presses, double-sided printing can be realized by changing the transfer route of the substrate, or by turning rollers.

  2. Printing materials can be a wide range of hard materials such as sheet paper, cardboard, corrugated paper, can also be in the form of web, such as self-adhesive paper and newspaper materials. The viscosity of the printed material must be accurately measured with a viscosity cup.

  3. The printing unit and processing function can be flexibly configured according to the needs of users. The unit type flexo printing machine can be convenient to install auxiliary equipment, and auxiliary joint processing can be carried out after printing, such as glazing and die cutting. Easy to operate and maintain, with good performance, you can use Dyne pen to measure the tension.

  4. Suitable for short plate live printing units more stations, a multi-purpose machine, for less batch, delivery time is urgent, need to use more stations of special printing, the use of this kind of equipment has advantages.

  5. Now high-speed multi-color printing parts standardization, parts universality, product serialization degree is high, in the design of advanced. Such as equipped with tension, edge, alignment automatic control system.

  6. The spacing between each embossing unit of the short-distance arrangement flexo printing machine is small, which is convenient for multi-color overprinting. Therefore, this machine can be used for printing small prints such as trademarks and packaging boxes with higher accuracy. For printing materials with smaller scalability, the overprinting effect is also better.

        The reason why flexographic printing press develops at a constant speed is that in addition to the technological breakthrough of plate and ink, its own characteristics are an important reason to attract users. Its characteristics are as follows:

(1) The machine is simple in structure and easy to operate and maintain. The price of flexographic press with the same function is about 30-50% of that of offset press or gravure press.

(2) The genetic material has strong adaptability, and satisfactory printing results can be obtained from 0.22mm plastic film to 10mm corrugated cardboard.

(3) The imprinting force is small, about 19.6-39.2n/cm2, especially suitable for printing corrugated paper and other substrates that can not withstand excessive pressure.

(4) The low printing cost is mainly due to the low machine price, low plate making cost, low paper loss rate in the printing process, and 30-50% cheaper production cost than intaglio printing.

(5) The printed matter is of good quality. The anilox roller inking system with short inking path not only simplifies the structure of the inking system, but also realizes the quantitative control of film thickness. The breakthrough of high-performance photosensitive resin plate technology has greatly improved the resolution and dot reproducibility of the printing plate (up to 1-95%). Flexographic printing can achieve 300 lines / inch color level printing, and the printing effect can be comparable to offset printing and gravure printing.
