Fountain Solution and Cleaner TPC

TPC is the English abbreviation of Japan's Toyochem Printing Chemical. This company is a joint venture between Japan's Toyo Ink Corporation and Graphic Printing Chemicals, a world-renowned printing ink manufacturer. It specializes in the production of fountain solutions, cleaners and other printing chemical protections for use with Toyo Ink. Supplies company. Now, the printing chemical products produced by TCP have been sold all over the world.

As we all know, in the past, printing factories mainly used petrol to clean ink rollers and blankets. This practice is not only flammable, pollutes the environment, but also accelerates the corrosion and aging of the blanket. Now, this practice has not only been eliminated in foreign countries, but is also gradually being eliminated in the country, and replaced by a variety of water-based cleaners.

On the other hand, what is commonly used on printing presses is the alcohol dampening system. Compared with the traditional hydrated version, this dampening method can greatly reduce the amount of water, thus avoiding the paper deformation and the excessive emulsification of the ink due to the large amount of water. However, since alcohol is a chemical that is harmful to the environment and to the human body, reducing alcohol consumption is an inevitable trend.

In fact, fountain aids such as fountain solution and detergents not only ensure the working quality of dampening system and ink supply system, improve the quality of printed matter, but also provide printing consumables that are also important for improving working conditions and preventing environmental pollution. The TCP company is the leader in the development and production of various printing chemical additives. The following describes some of the major products of TCP for users' reference.

1 Violet Fountain (Violet Fount)

Ziquan fountain solution is a fountain solution specially designed for rotary offset presses using thermosetting inks and cold suspect inks. It contains preservatives to prevent bacterial growth in dampening systems, as well as powerful wetting agents and fat-reducing fats, which can be quickly cleaned, reducing paper waste and downtime.

In the conventional dampening system, a 2% to 4% Ziquan dampening dilution can be used, and its pH should be between 4  8  5  2 . When using the alcohol dampening system, the amount of alcohol should be between 8% and 10%.

With this fountain solution, the consumption of ink can be reduced, the amount of water and alcohol can be reduced, and the short-time shutdown eliminates the need to apply protective glue to the plate, making it suitable for high-speed printing presses.

2 Multi Fountain Fluid (MultiFount)

Duo Quan fountain solution is a high-quality, multi-purpose fountain solution for sheet-fed presses. Suitable for conventional alcohol dampening systems and DirecttoPlate's alcohol dampening system, it can also be used in traditional moist dampening systems.

When more than one fountain solution is used for the alcohol dampening system, 8% to 10% of alcohol need to be added. It can form a very thin wetting film on the printing plate, will not cause smear or excessive emulsification, guarantee the printing product clean and bright color, reduce the amount of ink at the same time.

Duoquan fountain solution dilution ratio of 2% to 4%, pH value 4  6 ～ 5  0.

3843 rubber roller and blanket cleaner

843 Cleaner is a commonly used cleaning agent that can effectively remove the ink and dirt on the ink roller and blanket. It can be mixed with water to form an emulsion, which can effectively remove ink, paper, dust and dirt. Or automatic cleaning device, does not damage the ink roller, blanket and photosensitive resin plate.

When cleaning the blanket, apply a cleaning agent with a cloth or a lint-free cloth, apply it to the ink roller and the blanket, and remove the ink several seconds after permeating the ink layer, and then wash it with water. It can also be mixed with fresh water and detergent (5% each). When cleaning the ink roller, the cleaning agent is first added to the ink roller, and then the ink roller is driven so that the cleaning agent is evenly distributed on each roller, and then the ink is removed with a scraper. The ink roller after cleaning should be stopped for a few minutes before adding new ink.

4 special strong ink roller calcium cleaning agent

Due to the large amount of calcium in paper and hard water, the ink roller will be calcified for a short period of time during the printing process, resulting in printing failures such as non-inking, uneven bars, and uneven ink printing. Calcium removal agent is a new product that can quickly and effectively remove the calcium material of the ink roller. It does not need to disassemble the ink roller when it is used. It is convenient and saves time, and it will not cause the aging of the ink roller, and at the same time, the time needed to use the accumulated grease is solved. Longer deficiencies.

With the continuous improvement of the grade of printing equipment, high-quality, high-performance ink rollers and blankets have been continuously applied. We advise users to use fountain solutions and cleaners that can match inks, rollers, and blankets in order to give full play to the advantages of the former in terms of quality and performance.
