Difference Between Weak Solvent Ink And Solvent Ink

Dec 03 , 2019

Inkjet inks can be roughly divided into water-based inks, solvent-based inks, and UV-curable inkjet inks that have just been developed in recent years according to their main components. The main characteristics of water-based inks are low cost, no pollution, and bright colors, but because its main component, water, has a slow volatilization rate, the inkjet screens of water-based inks are not easy to dry and absorbed by the medium (it requires a special coating for the medium) , It is mainly used in paper and various media (cloth) as the substrate and coated media. The screens usually made of water-based inks are mainly used indoors because of their poor weather resistance, and solvent-based inks are basically used as outdoor applications. The main components of solvent-based inks are organic solvents. Generally, solvents such as esters and ketones are used. In the process of combining with the medium, the medium is first swelled and then fused to tightly combine the colorant and the substrate in the ink. The type ink does not require the medium to be coated, and its evaporation speed is fast, which can meet the requirements of high-speed printing. As the market size of outdoor photo machines continues to expand, the use of weak solvent inks for important consumables is also becoming more widespread. So what are the advantages of weak solvent inks? The supplier of the Large Inkjet Printer Solvent Ink will tell you below.


Weak solvent ink, also known as environmentally friendly solvent ink, is a new type of outdoor solvent spray with high safety, low volatility, low to low toxicity, and high flash point that has been popular in the outdoor solvent-based digital inkjet market in recent years. Ink, its development has not stagnated. At present, some people have put forward higher requirements to develop it into green solvent outdoor inkjet.


Six outstanding properties of weak solvent inks:

(1) Beautiful and rich colors, realistic effects, wide color gamut, excellent color expression;

(2) Waterproof, abrasion resistant and not easy to discolor.

(3) Adopt imported raw materials, good dispersion stability, no plugging;

(4) Long-lasting outdoor performance, can resist the influence of UV light and prevent color fading;

(5) Does not contain benzene, toluene, xylene, cyclohexanone and other toxic solvents, and has a very small taste;

(6) Good adhesion and quick-drying.

Comparison of Mild Solvent Ink and solvent-based inks:


Compared with solvent-based inks, the biggest change of weak-solvent inks is the environmental friendliness, which is mainly reflected in the reduction of volatile VOCs and no longer using many toxic organic solvents, which is no longer needed in the production workshop of weak-solvent inkjet printers. Ventilation. However, we must see that the main component of weak solvent ink is still organic solvents. Objectively speaking, weak solvent ink is a classification of solvent-based inks, and it is an environmentally friendly "version".


Eco-friendly and high-precision features are commonly advertised by machines using weak solvent inks. In the production process of inks, in addition to the selection of environmentally friendly solvents, weak solvent inks also have two higher requirements compared to solvent-based inks: one is to control the ink dispersion better in order to achieve high-precision output The other is that the filtration precision of the ink production process is higher.


Ink is a high-consumption consumable and one of the key factors affecting print quality. Our suggestion is: choose the weak solvent ink according to the manufacturer's matching ink, and do not change the ink of different brands frequently. The above is a detailed introduction to the Resistant Sublimation Ink Supplier, and I hope to help you.
