Alcohol-free fountain solution operational performance

2020-05-21

Although the Alcohol-Free Fountain Solution is similar to alcohol in the process of printing, it can improve the dispersion of water, speed up the flow rate and leveling. But the use of Alcohol-free Fountain Solution than the use of alcohol more cost-saving, more safe, no pollution, each shift can save about 35% of the cost of moisturizing materials. Today to introduce the alcohol-free Fountain Solution Use performance characteristics and its function.

1. the speed of ink drying on a print, the difference between the use of alcohol and the use of alcohol-free fountain solution: using alcohol or alcohol-free fountain solution, Printing Ink drying speed is the same. Only air temperature, humidity, water absorption of paper, solvent volatilization speed in ink, etc., is related to the speed of ink drying on printed matter, and the fast and slow drying of printed matter is not related to the use of alcohol or alcohol-free fountain solution.

2. the use of alcohol-free fountain solution, the effect on the ink color of printed matter: it will not have an impact on the ink color of printed matter, because the ink is oily material, the production material of alcohol-free fountain solution is water-sensitive material, hydrophilic material and oily material are not compatible, so the ink color of products printed with alcohol-free fountain solution will not change.

3. why alcohol should be replaced with alcohol-free fountain solution: alcohol-free fountain solution, although similar to the role of alcohol in the printing process, both in the water to improve the dispersion of water, speed up the flow of water and leveling and other functions. But the use of alcohol-free fountain solution than the use of alcohol more cost-saving, more safe, no pollution, each shift can save about 65% of the cost of moisturizing materials.

4. the difference between alcohol-free fountain solution and alcohol: the molecular weight of alcohol is small, while the material with small molecular weight is volatile. The alcohol can reduce the temperature of the Ps Plate when the plate volatilizes, and when the temperature of the PS plate is lower than the air temperature, the moisture in the air changes to the liquid to stick to the PS plate, so when using alcohol PS plate the layout has an additional water supply source. Alcohol-free fountain solution of the large amount of material, large amount of material is not volatile. remind, PS plate the layout temperature and air temperature are close, the moisture in the air can not fall on the layout, the water obtained by using alcohol-free fountain solution PS plate is only supplied by water roller.

Functional:

1. increase the viscosity of the fountain solution.

2. alcohol can sterilize the fountain solution, the alcohol problem is obvious.

3. reducing the tension on the liquid surface, water becomes more "wet" to facilitate its diffusion in the hydrophilic part of the plate.

4. alcohol the toxicity is high, the isopropanol content is generally required to be below 400 ppm, but is often greatly exceeded in the printing shop.

5. feasibility: in the aspect of feasibility, it is necessary to point out that the alcohol-free fountain solution can not be applied to the printing press at will, and communicate closely with the printing operator, and it is absolutely necessary to adjust the machine carefully.

6. necessity is reflected in the use of alcohol-free fountain solution, the function mentioned above will be preserved, while the existing problems will be overcome, saving money, environmental protection and labor protection, enterprises, society and workers will benefit. In particular, because alcohol is actually a kind of active ink thinner, it will make ink lose luster, and affect color. No alcohol after all this problem, ink will be reduced, dot more accurate, printing paper will also dry faster.
