Inkjet technology is the procedure where industrial inkjet barcode printers emit small droplets of ink onto a substrate without the print-head essentially making any kind of physical contact. Dots of diverse colored inks combine to give photo-quality imaginings. The key challenge lies in accomplishing a high level of accuracy and dependability. The dots are smaller than 70 microns and henceforth, the heads has to be positioned specifically so as to accomplish good resolution and print quality. This accuracy is only accomplished using a blend of science, technology and design. Although industrial inkjet barcode printers technology has been around since the 1950s, its solicitation in an industrial milieu is being reconnoitered only of late. Industrial inkjet printing systems are generally categorized into two categories-continuous printing (CIJ) or drop on demand (DOD), with variations within every classification. In the case of unremitting inkjet technology, the drops are expelled unremittingly from the print-head, while in case of drop on demand technology, drops are emitted from the print-head only when needed.
In the incident of CIJ, a pump directs fluid from a tank onto one or more trivial nozzles, which emit a constant stream of drops at very high frequency. The high frequency is accomplished using a piezoelectric crystal. The drops are then made to lead through electrodes, which impart a charge onto every drop and then made to go through a deflection plate. An electrostatic field is upheld and this decides which drops are expelled and which drop is collected and re-circulated back. As piezoelectric technology is used, a high-speed inkjet printing is conceivable. Further, the high swiftness of the drops offers a comparatively huge distance between the print-head and the substrate. The key benefit of this method lies in the fact that high printing speeds can be accomplished. The inks used are solvent-based and this means that good adhesion and speedy drying are possible. High upkeep is needed for the print-heads and the technology is not environmentally friendly.
In the situation of drop-on-demand technology, the drops are expelled only when needed. The drops are made when a pressure-pulse is produced. In one sub-variant named thermal inkjet technology, drops are formed by speedily heating the ink in a trivial chamber. Expulsion of the drop leaves a vacuum, which is then substituted by the subsequent flow of ink. In the other sub-variant, an electric arena is applied to a peizoelectric crystal. The speedy distortion so created causes a pressure pulsation, which in turn causes the droplets to be emitted from the nozzle. Industrial inkjet printing technology is extensively used for coding and marking merchandises and packages. The application spans a widespread diversity of industrial applications right from food and drink to pharmaceuticals, electronics and construction.
