Manufacturing
Production Process
Hard resin/Varnish Process
The ‘Hard Resin’ is the main ink raw materials composed of natural rosin. Kwang Myung Ink is making ink and varnish with 100% self produced hard resin.Having its own hard resin technology, Kwang Myung Ink has been manufacturing 10 different hard resins by condensation reaction. As these various hard resins have their own characters, two or three hard resins need to be mixed together in ink and varnish production; which can maximize the advantages of each hard resin.
Blending/Aging process
Powder putting colors into inks is called ‘pigment’. It is the ‘blending process’ that mixes and melts pigment into liquid varnish. To mix up completely solid pigment and liquid varnish, the mixture needs to go through ‘aging process’ in a heated tank for 24 hours.
Dispersion process
It is the ‘dispersion process’ that crushes up pigment finely to be melt into liquid varnish perfectly.Dispersion process is one of the most critical process determining the quality of ink.The smaller particle size of the pigment in inks guarantees the better inks transfer on printing rollers in press and ultimately on the printed materials. Kwang Myung Ink is operating fully automatic dispersion process for 24 hours equipped with state of the art automatic bead mills such as K-240, K-120 and Cobra-mill from Bühler Switzerland.
Adjustment process
It is the ‘adjustment process’ that modifies the mass produced base inks in accordance with each customer’s specifications (Tack, Viscosity, Flow, Drying time, etc.) by adding various additives. The massive database has been built in Manufacturing Execution Systems(MES) on specifications and requirements by customer, item, country and season; which controls the adjustment process automatically.
Packaging process
The packaging process is the final production process that prevents the ink from drying and oxidizing by blocking the air contact with the surface of the ink beyond simply containing the ink in the packaging container.
In order to maximize the shelf life of the finished product in any environment and climate from -40 ° C to + 50 ° C in the world, Kwang Myung Ink has advanced automatic packaging facilities.
Kwang Myung Ink has the packaging facility that provides all the ink packaging solutions used in the global printing market.
