Editing Flexography (section)

===Ink controls===
The ink is controlled in the flexographic printing process by the ink system. The ink system contains an ink pump, anilox roll and either a [[fountain roll]] system or [[doctor blade]] system. The fountain roll or two-roll system has one roll spinning in an ink pan pressed against the anilox roll to transfer a layer of ink to then be applied to the printing plate. This system is best used for low quality print such as flood coats and block lettering due to its inability to produce a clean wipe of the anilox roll. The doctor blade system can either be an open single blade system or an enclosed dual blade system. The single blade system uses an open ink pan with a roller that is then sheared with one doctor blade to create a uniform layer of ink to be distributed. The remaining ink sheared from the anilox roll will collect in the ink pan to then be pumped back into the system. The cylinder plate, anilox, and doctor blade are independently controlled by hydraulic, pressure and/or pneumatic systems. This system is best used for low to mid quality print work - usually found in corrugated box printing. The dual blade system is an enclosed system that has one doctor blade for doctoring the ink and one containment blade that contains the ink in the chamber and allows ink from the anilox roll back in. Dual blade systems require 2 end seals and adequate chamber pressure in order to maintain the tight seal between the ink chamber and the anilox roll. This system is best used for high quality, intricate print designs, like those found in the label industry.
