Why is the anilox roller so important?
The purpose of the anilox roller is to pick up ink from the fountain roller (or, in some configurations, directly from the ink fountain) and deliver a predetermined, metered, uniform amount of ink to the rubber printing plate.
What is ink spitting?
Spitting is when the ink is sprayed on to the web in an uncontrolled manner. This is caused when the doctor blade lifts because of excessive doctoring pressure allowing the UV ink to pass under the blade and spit on the web.
What is an anilox cleaner?
Anilox Deep Cleaner 3S The cleaning liquid is developed to deep clean aniloxes in the Flexo Wash machine. It is a water based strong alkaline liquid based on special surfactants. It is formulated to loosen the dried ink in the cells of the anilox. The liquid is corrosive to light metals, e.g. aluminium.
What is the purpose of an anilox roller in the flexography printing machine?
The Anilox Roller is often referred to as the heart of the flexographic press. It is designed to deliver a precise and consistent amount of ink to the printing plate.
What is BCM anilox?
Anilox Cell Volume. Cell volume is the capacity of the engraved surface in a square inch, expressed in billions of cubic microns (BCM). Higher volume translates to higher solid ink density, more color or a heavier coating thickness. Anilox cell volume changes over time, due to wear, plugging and cleaning procedures.
How do you clear the inks accumulation on the Dr Blade set?
Clean the chamber – A cleaning routine involves wiping down the chamber with a cloth and flushing with approved cleaning solutions every day to remove ink deposits and particles from the doctor blade and blade clamp.
Why choose anilox for your Flexo printer?
It is essential for all flexo printers that the anilox gives the correct ink density from the first print and stays consistent throughout the whole run regardless of which cell structure or shape is used, and the anilox manufacturers are going to great lengths to achieve this. By Michal Lodej.
How to clean anilox roll?
One of the most basic yet important concepts when cleaning the anilox roll is to do so as soon as possible. Letting the rolls sit in the press, not rotating or without a supply of ink, will cause that ink to dry in the cells. To prevent this, keep the ink and rolls circulating.
What technology is used in Anilox rollers?
Apex International, which recently changed its name from Apex Group of Companies, uses laser technology on its range of conventional anilox rollers and its GTT slalom cell structure anilox rollers. The base of the anilox is a steel roll, which then has a ceramic, titanium and water mix sprayed over it.
What is happening to the flexo print process?
In recent years the flexo print process has enjoyed a period of persistent growth thanks to new advancements in ink, anilox and plate technology, as well as printing presses.
