Is solvent-based ink on the way out? This seems to be a topic of great interest in the printing industry. In recent years, with the gradual increase in environmental awareness, many companies have begun to look for more environmentally friendly and sustainable printing solutions. Against this background, the question of whether solvent-based ink can continue to gain a foothold in the market has become a focus of attention. So, let’s learn about solvent-based ink.<\/p>\n
Solvent-based ink generally refers to inks that use various solvents as diluents, including alcohols, esters, benzenes, and ketone solvents. Due to the high toxicity of benzene and ketone solvents, the use of these two types of solvent-based inks has been banned in gravure cigarette label printing. In foreign countries, most gravure printing uses water-based inks to reduce solvent residues. In China, solvent-based inks are still mainly used due to the color gamut and drying problems in practical applications of water-based inks. [1<\/p>\n
As an important part of the printing industry, its performance is directly related to the quality and effect of the printed matter.<\/p>\n

Performance of solvent-based inks<\/b><\/p>\n
1. Good printability<\/b><\/p>\n
Solvent-based inks have moderate viscosity and drying speed, which can meet the needs of various printing equipment and ensure the clarity and color vibrancy of printed materials.<\/p>\n
2. Wide applicability<\/b><\/p>\n
Solvent-based inks are suitable for a variety of substrates, such as paper, plastic, metal, etc., and can meet the printing needs of different fields.<\/p>\n
3. High printing efficiency<\/b><\/p>\n
Solvent-based inks can dry quickly during the printing process, which improves printing efficiency and reduces production costs.<\/p>\n
However, according to experiments, the maximum average value of non-methane total hydrocarbons (NMHC) in the gravure continuous printing process using solvent-based inks reaches 5975.67 mg\/m3, which is about 31.2 times that of flexographic printing using water-based inks (191.67 mg\/m3)[2]. They are usually<\/b> volatile organic compounds<\/b> in the air, causing air pollution and potential harm to human health.<\/b><\/p>\n

Classification of solvent-based inks<\/b><\/p>\n
Solvent-based inks can be divided into several categories according to different classification criteria.<\/p>\n
1.According to the solvent’s<\/b> chemical properties<\/b>, we can divide them into several categories, including ketones, ethers, esters, alcohols (monohydric alcohols – aliphatic, alicyclic and glycolic), and hydrocarbons (aliphatic, aromatic, naphthenic). Within these categories, we can further distinguish between polar solvents, non-polar solvents, reactive solvents, inert solvents and strippers (rinsing agents).<\/p>\n 2. By solvent type<\/b><\/p>\n 3. By drying method<\/b><\/p>\n 4. By use<\/b><\/p>\n 3<\/b><\/p>\n Development of solvent-based inks<\/b><\/p>\n In recent years, the ever-increasing environmental protection requirements have also made the requirements for inks more stringent, mainly involving aspects such as no toluene, low VOCs emissions, low migration, and safety and hygiene. Against this background, the use of toluene-based solvents and ketone-based solvents is gradually decreasing, and the focus is shifting to more environmentally friendly ester solvents and alcohol solvents to reduce the burden on the environment.<\/p>\n On the one hand, the development of environmentally friendly solvent-based inks has become the mainstream in the industry, with the aim of reducing pollution emissions during the printing process. On the other hand, the rise of environmentally friendly inks such as water-based inks and<\/b> UV inks<\/b> has had a significant impact on the solvent-based ink market.<\/b><\/p>\n Under these circumstances, the solvent-based ink industry must actively promote technological innovation and environmental upgrades while maintaining high-quality printing results, in order to cater to market demand and meet environmental standards.<\/p>\n As for whether solvent-based inks will be phased out, this is not an absolute question. Although environmentally friendly printing solutions are gradually gaining a share of the market, solvent-based inks still have unique advantages, such as excellent printing results and a wide range of applications. Therefore, solvent-based inks are likely to continue to exist in the market for some time to come.<\/p>\n Looking to the future, the ink industry will continue to develop in the direction of alcohol-soluble, water-soluble and water-based inks to better adapt to current and future market trends and promote the application of more environmentally friendly packaging printing inks.<\/p>\n <\/p>\n <\/p>\n Quick answer:<\/strong> For wetting, leveling, defoaming, and dispersing topics, formulators usually compare performance and side effects together because over-correcting one surface issue can easily create another.<\/p>\n <\/p>\n There is a rapidly growing market demand for lead-free glass<\/b> inks. At the same time, the rapid development of the automotive industry has driven a strong increase in the demand for automotive tempered glass, which has also driven the development of automotive tempered glass inks, while also placing higher demands on the performance of the inks [1].<\/p>\n Because the lead content is quite small or no ink pigment is used, which greatly reduces the harm of pollution, it is often referred to as environmentally friendly glass inks.<\/p>\n 1<\/p>\n Application of lead-free glass inks in the automotive industry<\/p>\n Automotive glass inks are composed of low-melting glass, inorganic melanin and organic toner, and are usually printed around the edges of automotive glass, commonly known as the \u201cblack frame\u201d [2-3]. They have a decorative function, but also enhance the firmness of the bond between the glass and the car body, reduce the transmittance of ultraviolet light, etc. [4].<\/p>\n As lead-free glass inks can meet the automotive industry’s needs for environmental protection, safety and high-quality printing, in recent years, the application of lead-free glass inks in the automotive glass field has attracted more and more attention and favor. Common applications are as follows:<\/p>\n 2<\/b><\/p>\n Preparation of lead-free glass inks for automotive glass inks<\/b><\/p>\n \u2460 Preparation of SiO2-Bi2O3-ZnO lead-free glass ink [5<\/b><\/p>\n The composition of glass largely determines its structure and properties. According to tests, the use of SiO2-Bi2O3-ZnO lead-free glass powder as a glass ink has been shown to have a softening temperature of 575 \u2103 and a crystallization temperature of 600 \u2103, exhibiting good glass-forming properties. When the glass powder content is 60%, the automotive rear window glass ink coating prepared under the conditions of 680 \u2103 and 1.5 minutes of holding time meets the process requirements of the automotive rear window glass production line. The formed glass film has excellent luster, acid resistance and anti-sticking properties.<\/p>\n \u2461 Automotive glass ink prepared with lead-free low-melting point glass [6<\/b><\/p>\n experimentally studied the glazing process using R2O-Bi2O3-B2O3-SiO2 glasses as the research object. The effects of the Bi2O3\/B2O3, Bi2O3\/SiO2 and R2O (Li2O, Na2O, K2O) compositions on the glass structure and thermal properties were investigated using X-ray diffractometers, infrared absorption spectrometers, scanning electron microscopes and thermal expansion analyzers. Low-melting glass was applied to automotive glass inks, and automotive glass inks with good adhesion, blackness, opacity and gloss were successfully obtained.<\/p>\n <\/p>\n Additive selection is usually most effective when the team defines the defect first and then screens compatibility, dosage range, and process stage. That is often much more reliable than choosing only by chemistry family or by a single dramatic lab result.<\/p>\n Why does an additive that looks powerful in a beaker sometimes fail in production?<\/strong> Should the most aggressive additive always be preferred?<\/strong> <\/p>\n <\/p>\n <\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" This seems to be a topic of great interest in the printing industry.
