A brief discussion on the formula of fountain solution

Fountain solution, also known as fountain solution, dampening solution, bath solution. The dampening solution contains a wetting agent. In the offset printing, the dampening solution plays a role in three aspects: one is to form a water film on the blank part of the printing plate; the other is to supplement the hydrophilicity damaged in the printing process. Layer; third is to reduce the surface temperature of the printing plate. Nowadays, there are many manufacturers producing offset printing fluid products, such as German BOTTCHER Company, Beijing's Aibixi Company, and Shanghai's Lide Company. Although the role of these products are used for dampening, if subdivided, these products actually include two types: one is that it does not need to be diluted or diluted, and it can be directly added to the offset printing dampening system (commonly known as water bucket). The product used for printing can be called fountain solution; the other is the product that needs to be diluted and formulated before adding the offset printing dampening system, which can be called dampening additive.

The role of formula analysis:

<1>According to the development of new products, it is possible to analyze the basic recipes of samples, guide the direction of R&D, and help customers shorten the development cycle.

<2>According to the analysis of sample formulation, imitating production, leading competitors

<3> Find the root cause of product quality problems from the perspective of chemical composition, provide solutions, and refer to suggestions

The role of component analysis:

<1>For poor material properties, analysis of material composition, quality diagnosis, and finding the source of quality problems

<2>Helping customers to pay attention to the specified substance composition in the formula system and the content of each component to improve the product's indicators

<3> Qualitative analysis of samples, provide a list of material ingredients, provide reference for raw materials, reduce technical investment, and save costs
