When selecting environmentally friendly ink thinners, the following aspects need to be mainly considered:

Environmental characteristics: Choose thinners with low VOCs (volatile organic compounds) content, non-toxic or low toxicity, and good biodegradability. These features help reduce the impact on the environment and human health.

Solubility: The thinner should have good solubility to fully dissolve the ink, improve its fluidity, and ensure printing quality.

Volatility: The volatility of the thinner should be moderate, ensuring the drying speed of the ink without evaporating too quickly and causing a decline in printing quality.

Safety: Choose non-toxic or low-toxicity products to reduce harm to humans and the environment.

Cost-effectiveness: Under the premise of meeting environmental and performance requirements, select products with high cost-effectiveness to ensure printing quality while controlling costs.

Application scenarios of environmentally friendly thinners: Environmentally friendly thinners are suitable for various printing processes such as gravure printing, offset printing, flexographic printing, and screen printing, widely used in advertising, packaging, books, and other printing needs.

Composition of environmentally friendly thinners: Usually composed of base solvents (such as alcohols, ketones, esters, etc.) and additives. Base solvents have high dissolving power, while additives are used to adjust viscosity, flash point, and other properties.

In summary, when selecting environmentally friendly ink thinners, it is necessary to comprehensively consider their environmental characteristics, solubility, volatility, safety, and cost-effectiveness to ensure that environmental requirements are met while guaranteeing printing quality and efficiency.
