Doctor Blade Chamber System Flexo Supplier
The most recent development in the flexographic printing process is the Doctor Blade Chamber System Flexo. Two doctor blades are used along with an enclosed chamber to dispense the ink to the anilox roll.
An anilox roll is a hard cylinder, usually constructed of a steel or aluminum core coated by an industrial ceramic whose surface is engraved with millions of very fine dimples, known as anilox cells.
For color consistency and job repeatability, delivering and metering ink to the anilox roller needs to be done correctly. If it is, the system can realize the true volume of the anilox roller, by Michal Lodej.
Newer models have simplified loading and mounting designs, allowing easier installation and consistent blade contact angles with minimal pressure.
Doctor Blades Chambers System Flexo are an essential part of commercial printing. The meter controls the liquid ink, and it does this by wiping the cylinder surface of excess ink while the cylinder rotates in an ink supply. With perfect inking, perfect doctoring and extremely long blade life due to very low pressure and unique construction.
Doctor Blade Chamber System are now a standard on all central impression (CI) flexographic presses and high definition (HD) corrugated post printers. After years of being relegated to jobs with low graphics requirements, flexography now rivals other printing methods for quality and efficiency, due in part to advances in the ink delivery process. Specifically, Doctor Blade Chamber Systems allow for better control over ink film thickness, color consistency, ink consumption, cleaning costs and press run time.

Frequently Asked Questions(FAQs)
This a sealed, completely contained ink chamber that works along with the anilox to determine the volume of ink supplied to the transfer roll so that the ink film volume is kept consistent while printing.
By isolating the ink within an enclosed chamber that dictates how the ink is transmitted onto the anilox roll, it discourages the recirculating of unused ink, enabling manufacturers to operate with enhanced ink efficiency.
The chamber system may be configured for all ink types including water based inks, solvent-based inks and uv curable inks. The doctor blade, ink chamber, seals and pump material should be selected based on the kind of ink used.
Yes. Chamber width, arrangement of the doctor blade, the type of ink seal material used in the chamber end seals, as well as the pressure system and the overall design may be chosen based upon the design and function of the particular press being used.
