gravure printing ink viscosity

未分类 1℃ 0评论

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. Fast Sincere 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. Printing inks. Scuffs or scratches in the ink are likely caused by the ink itself, the press … Under the normal environmental humidity, the ink printing viscosity is above 16S (Zahn No. Controlling ink viscosity is the key to colour consistency because that is the factor subjected to the highest variability. 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. Rovene 6106 is a low viscosity but high solids letdown emulsion for paper and paper board substrates. In plastic gravure printing, how to control ink printing viscosity is a very important problem.

Temp. The percent solids of fluid is the characteristic of the ink that gives it colour. Viscosity Tables – Measurement data. 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. Rotogravure printing ink is thinned with toluene for faster evaporates, drying and setting to substrate. 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. 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. surface tension and viscosity) 44 in addition to trench resolution 24. Toyo Ink Pte. Solvent evaporation increases the pigment loading of the ink, resulting in poor print quality and excess ink consumption.
