How To Solve The Slow Drying Of Ink?

      If the ink can be fixed well, it is dried from the inside to the outside. In this case, although the ink surface can resist static pressure after solidification, the ink layer cannot withstand friction.How To Solve The Slow Drying Of Ink?

How To Solve The Slow Drying Of Ink?

      The common ink for offset printing mainly depends on chemical reaction for drying. The oxidation and high polymerization of ink rosin is the role of desiccant and an important component of ink.How To Solve The Slow Drying Of Ink. If the ink is not dry enough to resist the pressure of the next color, the paper cannot print the second color.How To Solve The Slow Drying Of Ink?

      Worst of all, if the ink needs to be dried for a long time, the medium containing rosin will excessively penetrate into the paper, and the ink film lacks the ability to bind pigment, which may lead to white deterioration. The operator should know that this trouble is very complex. It is based on unbalanced factors such as ink, paper and printing conditions.How To Solve The Slow Drying Of Ink?

      As drying is one of the chemical reactions, the temperature can affect its drying speed. Control the temperature of paper or printing room if it is under abnormal conditions. From 60 ° F V less than 0 ° f is ideal.How To Solve The Slow Drying Of Ink.If the amount of desiccant in the ink is not enough, pay attention to its characteristics and amount, and add some desiccant to the ink. But adding too much desiccant is not recommended. (refer to note).How To Solve The Slow Drying Of Ink?

       Too much wetting water will cause this trouble.How To Solve The Slow Drying Of Ink.Too much moisture in the paper slows down the drying rate. In this case, it is best to add strong desiccant.How To Solve The Slow Drying Of Ink.Too much acidity of wetting water (low pH) will reduce the activity of desiccant. The suitable range of pH is from 5.0 to 6.0. At a minimum, the pH value should be maintained above 4.5.How To Solve The Slow Drying Of Ink?

      For the same reasons above, it is very dangerous for the pH value of paper to be too low. When the pH of paper is too low, such as in non coated paper is lower than 4.5 and in coated paper is lower than 6.0, it is necessary to use strong desiccant or more ordinary desiccant than usual.How To Solve The Slow Drying Of Ink It is known that some synthetic chemicals in water tank liquid can have adverse effects on drying speed.How To Solve The Slow Drying Of Ink?

     If you find trouble after completing all the printing colors, you have to use up the oil to print again.How To Solve The Slow Drying Of Ink.Light is a kind of radiant energy in the form of electromagnetic wave. When the electromagnetic wave is 0.38-0.77 (its spectrum is called visible spectrum), any single visible spectrum is immutable and constant, and once the color is fixed, the spectrum reflected by it is also invariable and constant. How To Solve The Slow Drying Of Ink?

     So why does a chameleon change color? Because there are many special and displaceable pigment cells in its body, and it can adjust the distribution of pigment cells in its body according to the changes of external three primary color light, so as to achieve the effect of changing color.How To Solve The Slow Drying Of Ink?

      NDC – GBS can also be said to be an anti-counterfeiting technology inspired by chameleon. The active color produced by ndc-gbs technology is particularly sensitive to the length and strength of visible electromagnetic wave. How To Solve The Slow Drying Of Ink?

    This active color is wrapped by molecular encapsulation technology. How To Solve The Slow Drying Of InkThis active color will show different colors excited by different amounts of visible photoelectric magnetic wave,How To Solve The Slow Drying Of InK?

      which is not available in any anti-counterfeiting technology at present. If this change is applied to the trademark, the trademark will become an exclusive printed color pattern that cannot be copied.How To Solve The Slow Drying Of Ink?

     Our passive interferometric optical variable printing technology is one of the most advanced anti-counterfeiting technologies in the world. It has the characteristics of complex process, unique formula and long development cycle. How To Solve The Slow Drying Of Ink?

     Its manufacturing technology and equipment are the only ones we have, and we can’t buy raw materials and finished products on the market. With this analysis, the anti-counterfeiting effect of the anti-counterfeiting trademark made by this composite anti-counterfeiting technology is certainly better than the current anti-counterfeiting technology, and the market is very huge.How To Solve The Slow Drying Of Ink?

      In an investigation report of the anti-counterfeiting Intelligence Bureau of the International Chamber of Commerce in 1995, it was proposed that in order to have good anti-counterfeiting performance and get common application, a commodity anti-counterfeiting technology must meet a criterion: it cannot be copied by imitation and copying, and it is easy to be recognized by the public and traders; Easy to verify and cheap, can not be completely replaced,  How To Solve The Slow Drying Of Ink?

      wear-resistant. In order to meet the above conditions and have exclusive technology, the production conditions should also be practical, which can carry out large-scale industrial automation production.How To Solve The Slow Drying Of Ink?
