How to ensure the printing effect of the four - color carton printing machine
With the application of carton packaging is more and more widely, so that the carton machinery processing market development is also more and more fast. In carton processing, in addition to forming outside is the need for carton printing, carton printing carton printing machine cannot do without, then in the daily operation of production, which can help to improve the printing quality.
1, usually to the excess ink scraping clean, do not appear to hang, run, ink knife line, it must be linked to the placement of the hardness, height and angle adjustment placed right. www.chinacartonmachine.com
The hardness of the material 2, embossing rollers on the inking rollers, the hard material on the inking rollers, the soft material, a large quantity of ink. Roller pressure is small, on the contrary, it is a small amount of ink, ink quantity. Printing plate patterns need deep imprint rollers hard material; printing plate pattern embossing rollers to shallow, hard material, printing speed need to use some of the soft material embossing rollers.
3, always want to keep the consistency of the ink viscosity, to measure the timing, plus the solvent. Old and new ink to be used in proportion. Using a composite solvent, prevent the ink composition in proportion to the emergence of precipitation, anti rough, it is best to use ink and ink circulation of the stirring bar lei.
 

4, the ink is drying, not by heating and drying, the higher the heat in the printing ink is not easy to dry, the temperature is too high will make the surface of conjunctival ink, causing the surface dry inside dry conditions. Again in the ink of low boiling point solvent premature evaporation, high boiling point solvent residue, slow drying rate. Requirements of the drying box in 40-50 degrees can be, the wind can not be directly blown on the film, the heat can not be directly baked in the film surface, to have a good exhaust.
