The formulation of plastic wate r-based gravure ink sample was designed. Drovin™ B-60. Insufficient heat applied 7. Drovin™ B-30. There have been recent studies on gravure printing of AgNWs as transparent conductive films 25, 26, However, the best reported resolution was limited to 230 µm 25. Printing inks. Attack and increase. The viscosity of the solvent-based gravure printing machine ink is too high, causing scratches, biting, paste, and printing problems such as “orange peel”. 3 cup). The printing resolution of gravure printing is mainly dependent on ink properties (e.g. Gets into the pigment and all that. Gravure inks manufacturer:Gravure ink is multi purpose ink system,suitable for reverse as well as surface Gravure printing,Mutli-substrate ink suitable for BOPP, PET, PE , BON & PT cellophane, Paper and SP-PVC.That reduce inventories of fresh as well as press return inks.Robust ink system with flexible type of solvent system . Ltd. is established in the year 1977 specializing in manufacturing of Rotogravure Printing Inks - Gravure Printing Ink Manufacturers in UAE. 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. surface tension and viscosity) 44 in addition to trench resolution 24. In plastic gravure printing, how to control ink printing viscosity is a very important problem. Adopted by many OEM’s as their number one choice, INKSPEC’s Viscosity Control System is the most reliable in the market. Within this range, as the viscosity increases, the transfer amount is increased. Custom Solutions for Better Printing Results. The slightest changes in ink viscosity or temperature can lead to color variations and other imperfections like smearing or striping. Viscosity of the ink in the ink transfer process is also very important in the production of thin-film composite color printing ink viscosity control 13-25S (No. Wrong ink for the stock 3. 870 Ink, solvent and or varnish flow inconsistent 3.

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. Sign up with your email to get updates fresh updates about our events. Ink viscosity is an indicator to the percent solids of the fluid. 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. 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. Solvent evaporation increases the pigment loading of the ink, resulting in poor print quality and excess ink consumption. 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. Whatever your printing specialty may be, there is a good chance that your printing process is susceptible to variations and substandard finishes due to inadequate viscosity and temperature control. The ink printing viscosity is below 16S (Zahn No. The operator is responsible for changing over … 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. 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. 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. Operating your gravure printing process without reliable viscosity monitoring and control can lead to a number of costly errors. Under the normal environmental humidity, the ink printing viscosity is above 16S (Zahn No. Inks with proper viscosity and good dispersivity were prepared by changing pigment/binder ratio. Inadequate mixing SOLUTION 1. ... used in the inks 7.
