With its Viscosity Control Process, INKSPEC has increased the overall press productivity and colour consistency of thousands of printing and coating stations around the world. [°C] Dyn. Ink viscosity is an indicator to the percent solids of the fluid. The operator is responsible for changing over … surface tension and viscosity) 44 in addition to trench resolution 24. Drovin™ B-20. Especially in high-speed rotogravure printing, whether the ink printing viscosity is properly controlled is directly related to most of the quality problems such as the handling of the pigment, the dirty version, the gloss of the printed product, the solidity of the pigment, and the static electricity, which affects the printing. Toyo Ink Pte. Printing inks. Considering the ink viscosity and printing speed, it is therefore logical that the best metallic surfaces are achieved with UV screen printing (low-viscosity inks) and the worst are achieved with UV offset/UV letterpress printing. Inadequate mixing SOLUTION 1. Cost: Printing with incorrect viscosity harms more than just quality. 3, the ink viscosity. Ink systems, viscosity, surface properties of substrate material and dot structures on the gravure cylinder are the main factors that determine the print quality.

Adopted by many OEM’s as their number one choice, INKSPEC’s Viscosity Control System is the most reliable in the market. Scuffs or scratches in the ink are likely caused by the ink itself, the press … The printing resolution of gravure printing is mainly dependent on ink properties (e.g. Temperature dependence of ink viscosity One of the most important uses of viscosity measurement is to determine when and by how much ink must be diluted in order to compensate for loss of solvent during the printing process. gravure ink could not meet the requirements of printability in adherence, proofing density and dryness, the application of water-based ink on plastic had not been promoted. 4 Jinzhuyuan Street, Changlong, Huangjiang Town, Dongguan City. 3 cup), and the static phenomenon generally does not occur. The viscosity of the solvent-based gravure printing machine ink is too high, causing scratches, biting, paste, and printing problems such as “orange peel”. UV flexographic metallic inks are somewhere in the middle. 870 Know the variables in your painting process to ensurethat perfect finish. The factors affecting the viscosity are closely related to the temperature, the concentration of the component particles, the particle size, etc., and have little to do with humidity and pressure. Packaging Gravure Printing Problems and their Solutions On the following pages, you will find the information on the most ... Holes in the printed complete film viscosity, use active solvents area 2. Insufficient heat applied 7. Gravure inks are fluid inks with a very low viscosity that allows them to be drawn into the engraved cells in the cylinder then transferred onto the substrate. While some may not view this as the most dire of issues, it still affects your quality and can lead to waste and possibly rejections.
