Flexography Printing

Flexoprinting technology is suitable for particularly thin, flexible and hard films, for almost all paper types, thick cardboard material, packaging materials with a rough surface, tissues and pressure-sensitive materials... Automation Solutions; References

Flexoprinting is a relief printing technology where the image area is part of the raised surface of image carrier. Modern flexo printing system consists of a closed chamber doctor blade, the ink metering roller or anilox roller, the form cylinder as the image carrier and the impression cylinder.

The ink is pumped into the chamber where the doctor blades construction shears the ink onto the anilox roller which has tiny engraved cells. This enables the supply of a fine film of ink to the printing plate mounted on the next roll in sequence, the form cylinder. The ink is then carried by the raised portion of the image carrier and transferred onto the web. The impression cylinder supports the web when it the form cylinder.

Once each print deck there is an interstation dryer that removes enough volatiles from the ink so that the next print deck may apply another colour without altering the previous one. After the last print deck there is a much longer dryer that completes the heat setting of all the inks applied.
