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.

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.

When we are selling ink,we have been asked with our customer that before their supplier ink dry too fast so it cause skinning or dry too slowly are influence next work process.According to this,we would like to give some suggestion to them. 1.Ink dry too fast how to solve? Due to the high storage temperature and long storage time, the ink in the can forms a layer of crust on the surface. This layer of crust must be thrown away and cannot be used, which will lead to quantity loss. In order to prevent this problem from continuing to occur, we recommend that customers store the ink at a temperature of 20-25℃, and use the product within the shelf life. At the same time, some customers also reported that many times when workers get off work or go to eat, they will leave some of the opened ink in the ink can or on the ink fountain. When they go to work again, they will find that these inks cannot be used because they dry too quickly, resulting in ink waste and increasing their workload. In response to this problem, we can make two suggestions from the ink itself. One is to adjust the formula of the ink and reduce the drying speed. The second is to use it with an anti-drying agent, spray a layer of anti-drying agent on the surface of the placed ink to form a protective film. This can maintain the fluidity of the ink for a certain period of time. 2.Ink dry too slowly The ink film is not dry fast within the expected time and is easily smudged. This problem occurs when the amount of desiccant in the ink is insufficient, the drying speed of the binder is slow, the relative humidity in the printing workshop is too high, the acidity of the paper is too high, the humidity is too high, and the acidity of the fountain solution is too high. This problem can be solved by adding desiccant to the ink appropriately, reducing the acidity of the fountain solution, reducing the amount of water, switching to quick-drying ink, adjusting the relative humidity of the workshop to less than or equal to 60%, and maintaining air circulation in the workshop so that the printed products are in an environment with good air circulation.

Currently, most inks in the market require the application of powder during the printing process to prevent ink smudging on the printed surface. The use of powder has certain impacts on the printing environment and the health of factory workers. So, how can we address this issue? DAIHEI Ink has been focusing on finding a solution for over a decade and has collaborated with Japanese ink manufacturers to research and develop powderless inks, which significantly reduce or completely eliminate the need for powder application. DAIHEI Ink's DAIICHI-SPL powderless ink has three main highlights: Highlight 1: Powerful back dirty prevention agent We have innovatively developed a powerful back dirty prevention agent that is twice as effective as previous products. Highlight 2: Special wax formulation Using a special wax formulation, our ink can inhibit stickiness immediately after printing and has excellent durability. Highlight 3: Improved drying performance The ink remains non-drying on the machine but dries instantly on the printed material. It has strong water resistance, good transferability, and stability on the machine. Here are the benefits that can be expected by reducing or eliminating powder usage, as well as the precautions to be taken during printing: Benefits: 1. Improved quality in backside printing   For sheet-fed machines, reducing powder usage to 1/4-1/2 can achieve the same quality in backside printing as surface printing. 2. Increased productivity   Sheet-fed machines not only achieve the aforementioned quality but also reduce the number of rubber blanket washes due to  powder, thereby enhancing production efficiency. For double-sided machines, it reduces the cleaning frequency of the output section and improves productivity. 3. Reduced post-processing issues   It minimizes surface gloss caused by excessive powder and problems during pressure lamination. 4. Improved printing facility environment   Contributes to improving the factory environment by reducing the accumulation of powder at air conditioning vents, preventing issues when restarting the air conditioning after a prolonged shutdown.   Precautions during printing: 1.Paper selection It is known that certain types of paper have poor back dirty prevention effects. The effectiveness is related to the roughness of both sides of the paper, as the back dirty prevention agent cannot function properly on rough paper surfaces. 2.Powder application device The maintenance of the powder application device is crucial to ensure the stable dispersion of a small amount of powder. Additionally, each device has its own characteristics, and the powder output can vary significantly beyond a certain scale. Therefore, it is necessary to understand the characteristics of each machine. 3.Rubber blanket The selection of a suitable rubber blanket is important for the stable transfer of the back dirty prevention agent and wear-resistant agents in the ink onto the paper. From current knowledge, semi-hard rubber blankets yield good results. Soft rubber blankets tend to retain the back dirty prevention agent on the rubber surface.

Four-color printing Four-color printing is to use CMYK (cyan, magenta, yellow, black) four primary colors to overprint the color that customers need. In popular terms, it is the use of the different superposition of these four colors to get the required color, as long as the color has a gradual change is a four-color overprint. Four-color printing is superimposed with dots, and if you use a magnifying glass you can see dots of different colors. Spot color printing Spot color printing refers to the printing process of using other spot color inks other than yellow, magenta, cyan and black ink to reproduce the color of the original manuscript. In packaging printing, spot color printing process is often used to print a large area of background color. Spot color printing is a single color, no gradient, the pattern is ground, and the dot is not visible with a magnifying glass. Spot color ink Refers to a pre-mixed specific color ink, such as fluorescent pink, reflex blue, metal gold and silver ink, etc., it is not overprinted by CMYK four-color, color means accurate color. Spot color ink has three characteristics: 1. Accuracy Each set of colors has its own fixed hue, so it can ensure the accuracy of the color in printing, thus solving the problem of color transmission accuracy to a large extent. 2. Facticity Spot colors generally define a color by a solid color, no matter how light that color is. Of course, it is also possible to Tint the spot color to render any shade of the spot color. 3. Wide color gamut The color gamut in the color library is so wide that it exceeds the RGB representation gamut, not to mention the CMYK color space, so there is a large part of the color that cannot be rendered with CMYK four-color printing ink.
