Odor in printed materials is a common concern for clients, often leading to questions about the quality and safety of the product. While printing inks are a primary suspect, the reality is that the scent of a printed piece is a complex interplay of various components used in the offset printing process. Understanding these sources can help both printers and clients manage expectations and address concerns effectively.   1.The Scent of Ink: Mineral Oil vs. Vegetable Oil Offset printing inks are primarily composed of pigments, resins, and solvents, with the solvent base significantly influencing the ink's odor profile. Historically, mineral oil-based inks were prevalent. These inks are known for their robust performance but can emit a distinct, often stronger, chemical odor due to the volatile organic compounds (VOCs) present in mineral oils. This traditional scent is what many associate with freshly printed materials. In response to environmental concerns and demand for milder odors, the industry has increasingly adopted vegetable oil-based inks, including soybean oil inks. These inks are formulated with renewable resources and generally have lower VOC emissions, resulting in a less pungent and often more neutral smell . While they are considered more environmentally friendly and typically produce a milder odor, it is important to note that even vegetable oils can cross-link and produce VOCs during the drying process, contributing to the overall scent . The specific type of vegetable oil (e.g., soybean, linseed) can also subtly alter the ink's inherent aroma.   2.Beyond Ink: Other Contributors to Print Odor Attributing all print odor solely to ink can be misleading, as several other factors in the printing process can contribute significantly to the final smell of a printed product: •Paper: The paper itself can be a major source of odor. Different paper stocks, especially those with coatings, recycled content, or specific pulp treatments, can have their own inherent smells that become more noticeable after printing and drying. •Fountain Solution: This critical component, a mixture of water, alcohol (or alcohol substitutes), and various additives, plays a vital role in the offset process. The chemicals within the fountain solution, as well as its pH and conductivity, can interact with the ink and paper, potentially generating or amplifying odors . Issues like an overly acidic or warm fountain solution can destabilize ink and contribute to undesirable smells . •Drying and Curing: The drying or curing process of the ink is crucial. If inks, particularly UV inks, are not properly cured, residual uncured components can emit strong, unpleasant odors . Adequate ventilation and proper drying conditions are essential to minimize this. •Adhesives and Coatings: Any additional adhesives used in binding or finishing, or protective coatings applied to the printed surface, can also introduce their own distinct odors.   3.Conclusion It is essential for clients to understand that some level of odor is inherent in printed materials due given the chemical nature of the printing process. The type of ink used—mineral oil, vegetable oil, or soybean oil—will certainly influence this. However, a strong or unusual odor is not always solely an ink issue. A comprehensive analysis should consider the paper, fountain solution, drying conditions, and other post-press treatments. Open communication between clients and printers about odor expectations and potential sources can help ensure satisfaction with the final printed product.

The concept of "green printing" originated in the late 1980s and was first proposed and implemented by developed countries such as Japan, the United States, and Germany. "Green printing" refers to a printing method that has little impact on the ecological environment, less pollution, and saves resources and energy. Its core connotation is "environmentally friendly" and "healthy and beneficial". With mankind's emphasis on environmental protection and the advancement of the concept of "sustainable development", "green printing" has become a printing method and requirement that is commonly used and increasingly popular in developed countries in Europe and the United States.   In April 2019, during the Guangdong International Printing Exhibition, the China Printing and Equipment Industry Association, Beijing Printing Association, and Beijing Green Printing and Packaging Industry Technology Research Institute jointly hosted the "Discussion on VOCs Emission Control and Governance Strategies for Publication Printing Enterprises." An important conclusion of the meeting is that publication printing is not a heavily polluting industry. It is recommended to strengthen source control and use green raw and auxiliary materials. Even without adopting "end-of-pipe treatment", emissions standards can be achieved.   As a printing ink manufacturer that takes green environmental protection as its mission, DAIHEI INK insists on using green raw materials to ensure that the products it produces are more environmentally friendly and safer. It has been registered in the "Green Raw and Auxiliary Materials" for 8 consecutive years. We firmly believe that every bit of our efforts can bring more contributions to society and achieve sustainable development of the enterprise.

Ink piling is the phenomenon that ink accumulates on the printing plate, ink roller and rubber blanket during the printing process, causing the dots to become fuzzy and unable to print smoothly. This phenomenon can be seen from the changes in the ink film on the roller, which becomes thick and the surface is rough and matte. Because of after the ink is emulsified by the fountain solution, the binder loses the function of carrying the pigment.And ink becomes short and slurry, resulting in poor ink distribution, poor transfer performance, or too high pigment content in the ink. In multi-color printing, if the viscosity of the ink printed later is too high to overprint, a lot of ink will also accumulate on the rubber blanket.Or caused by the poor water resistance of the pigment.Poor dispersion in the binder, incomplete wetting.Too high relative density, small oil absorption, coarse and hard particles.Ink quantity too much.Oil-water unbalance, too much water, etc cause this problem. The problem can be solved by adding suitable, relatively thick binders, wax additives, vaseline, etc.To improve the water resistance of the ink, reducing the amount of ink supplied, reducing the amount of fountain solution used, lowering the acidity of the fountain solution, using better quality paper, choosing suitable pigments (such as pigments with relatively low density) to manufacture inks, and changing inks.
