Versión en español: Leer en español Surface Energy Testing for Adhesion (ISO 8296 & ISO 2835 Guide) Surface energy is one of the most critical factors affecting adhesion between substrates, inks, and coatings in printing and packaging applications. In flexographic printing and industrial coating processes,... Continue reading

In coatings, inks, and flexographic printing, consistency is not achieved by formulation alone—it depends on how materials interact with surfaces. Leneta charts are one of the most widely used tools for evaluating opacity, contrast ratio, and coating performance under controlled conditions. Choosing the right chart—and... Continue reading

Common Coating Defects and How to Identify Them (Using Leneta Charts) In coating and printing processes, defects are not always caused by formulation issues. In many cases, they are the result of surface energy variations, contamination, or improper application conditions. Identifying these defects early is... Continue reading

Introduction In flexographic printing, achieving accurate Pantone colors depends on more than just ink formulation and substrate preparation. One of the most critical — and often underestimated — variables is the drying process. 👉 Even if your surface energy is correct and your ink is... Continue reading

Introduction Pantone is the global standard for color communication across industries. Designers, brand owners, and printers rely on it to ensure consistency — from concept to final production. But in flexographic printing, achieving an exact Pantone color is not always straightforward. 👉 The reason is... Continue reading

K Hand Coater Bars are precision tools designed to apply uniform coatings in laboratory testing, printing, and surface evaluation processes. Because of their fine wire-wound construction, they are also delicate instruments that require proper handling and maintenance. Understanding how to protect and maintain your K... Continue reading

Introduction Lamination failures are often attributed to adhesive performance, process conditions, or equipment settings. However, in many production environments, the root cause lies elsewhere: surface condition. Even when adhesives, temperature, and pressure are properly controlled, inadequate surface energy can prevent proper bonding—leading to delamination, weak... Continue reading

Which Dyne Test Kit Do You Need? 🟢 Intro Most surface energy problems in printing and converting don’t come from the ink or substrate. They come from incorrect testing ranges. Choosing the right dyne test kit ensures accurate measurements, reliable adhesion, and consistent production quality.... Continue reading
