In high-speed printing production, foam is an invisible killer that affects quality and efficiency. Foam in the ink system can cause pinholes, white spots and orange-peel texture on the surface of printed materials, resulting in incomplete patterns and uneven color; in severe cases it can even cause the printing press pump to run dry and the ink transfer to become unstable, directly slowing down production progress and increasing the defect rate and costs.
Common defoamers on the market often face pain points such as poor compatibility, insufficient persistence or adverse effects on ink gloss. To address these core challenges, Chemi Tech, drawing on years of focused research and development, has launched a series of efficient ink defoaming solutions. Our defoamers are not a simple additive, but are based on molecular design grounded in a deep understanding of ink resin systems, solvent combinations and printing processes.
The specific solution is divided into three steps. The first step is precise diagnosis: our technical team analyzes the type of ink used by the customer, the printing speed, the equipment parameters and the main stages where foam occurs. The second step is customized matching: based on the diagnosis results, we select models with good compatibility, fast defoaming speed and long-lasting foam suppression from our library of silicone, silicone-free and mineral-oil-based defoamers, and verify them through sample testing. The third step is process optimization: we provide recommendations on the optimal dosing timing, dosage and stirring method to ensure that the defoamer is stably dispersed in the ink and delivers a long-lasting effect without side effects.
We once served a company specializing in high-end packaging printing. When the company used a certain type of composite ink for high-speed gravure printing, a large amount of fine foam was continuously generated at the ink tank and the ink transfer roller, causing frequent local white spots on the printed products and keeping the daily defect rate high. After on-site investigation and laboratory simulation by Chemi Tech engineers, we recommended a silicone-free, highly efficient defoamer and guided the customer to add it in trace amounts at specific points in the ink circulation system. After application, the foam was quickly eliminated at its source, the surface of the printed products became uniform and smooth, the white spot problem was completely solved, production efficiency increased by about 15%, and the customer was very satisfied with the final printing results.
Choosing Chemi Tech means choosing a systematic method of controlling foam from the source. We provide not only products, but also a reliable guarantee for smooth printing processes and excellent quality.
