Viscosity Tables – Measurement data. tives of the DfE Gravure Partnership by: • Developing information on the effects of ink Two colors of nitrocellulose (Type C) ink common to temperature on solvent consumption and print packaging printers were used in 3-hour production runs on quality. As the viscosity becomes smaller, electrostatic phenomena such as whiskers, streaks, marginal crowding, flying ink, poor handling, and extremely irregular water stains will follow. A total 5 layers of R2R gravure printing and 4 layers of R2R coating using 8 different electronic inks (Figure 1a) are needed to complete the tag to demonstrate the basic working concept of the smart packaging: wireless power supply, sensor and signage. Operate 55" Bobst, Zerand, and Cerutti gravure printing presses (roll fed, in-line platen/flat bed die cutting). Rotogravure printing ink is thinned with toluene for faster evaporates, drying and setting to substrate. The slightest changes in ink viscosity or temperature can lead to color variations and other imperfections like smearing or striping. GRAVURE TROUBLESHOOTING www.VISCOSITY.COm saint clair systems norcross Color Variation Problem: Inconsistent color reproduction CAUSE 1. Controlling ink viscosity is the key to colour consistency because that is the factor subjected to the highest variability. 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. Drovin™ B-30. Mixing incompatible or old inks 5. Knowing the density and viscosity of ink is of great importance for ink producers because these physical properties provide important information on the quality and utilizability of the raw material and the final product. 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. Ink systems, viscosity, surface properties of substrate material and dot structures on the gravure cylinder are the main factors that determine the print quality. Published by When the operator was not able to pay as much attention, significantly more material was applied. Inks with proper viscosity and good dispersivity were prepared by changing pigment/binder ratio. PVB resins for Flexo & Gravure Printing Inks. Custom Solutions for Better Printing Results. Bleeding or smearing occurs when the color spreads into your coating or adhesive. Stop Scuffing in Its Tracks. If you aren’t able to maintain the proper viscosity of your ink, it may not dry before reaching the next station on your press, leading to issues like smearing or smudging. The viscosity of the ink at the point of use is not more than 5 poises and is preferably between 0.5 and 1.0 poise. Wholesale Hot Sealed Candy Opp Packing Bag, No. Fast Sincere Attack and increase.

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. Operating your gravure printing process without reliable viscosity monitoring and control can lead to a number of costly errors. The ink printing viscosity is below 16S (Zahn No. Solvent evaporation increases the pigment loading of the ink, resulting in poor print quality and excess ink consumption. 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.
