Flexography Process, History and Mechanics

Flexography

printingchillers-flexography-15Flexography is the process in which labels, and packaging products are produced and printed. The process uses flexible printed plates made of rubber or plastic to create the labels. The slightly raised plates are rotated on a cylinder, and then the picture is transferred on the medium. Quick drying inks, high speed printing process, and multiple types of material absorbent and non-absorbent are used.  Started in the late 1800’s, the technique developed into the 1900’s by way of food packaging in the United States.  Flexography uses four different types of cylinders. The first roller transfers the ink from the pan. Once the cylinder is coated it then rolls along the meter roller or Anilox roller and makes the ink a uniform thickness onto the plate cylinder. The plate cylinder then rolls across the medium. The medium is wedged between the impression cylinder and plate cylinder. The impression plate then moves the wet product to a cooled drying room.printingchillers-flexography-14
