The difference between ordinary printer and inkjet printer
In the current market, there are points: ink wheel coding machine, ribbon coding machine. There is also an ink coding machine, which is also an inkjet printer! They all have their own differences! Ink-wheel coding machines are widely used, such as those used by small companies. The reason is simple. The price is the most affordable. His disadvantage is that it is easy to wipe off, and the adhesion is not strong! Now that the strict requirements of the food industry and the increasingly critical level of customers, these machines are almost eliminated. And the ribbon coding machine. The price is more expensive than the ink wheel coding machine. The print looks better and is more difficult to wipe. It looks very clear! But the printing effect is not as good as the inkjet printer, to some extent it is the inkjet printing effect of the imitated inkjet printer. If there is an oily food belt, the printing effect will not be very good! Let's talk about the Shanghai multi-source inkjet printer. His performance may be the best equipment used in the packaging industry. His consumable is ink. For different targets, different inks can be configured, so the printed fonts cannot be erased. The effect is very clear and beautiful. Shanghai Multi-source inkjet printer is like a computer, it is a non-contact inkjet marking system controlled by a single-chip microcomputer. By controlling the internal gear pump or supplying compressed gas from the outside of the machine, a certain pressure is applied to the ink in the system, so that the ink is ejected through a nozzle with an aperture of several tens of microns. The crystal oscillation signal applied above the nozzle splits the continuous ink line into ink droplets with the same frequency, the same size, and a certain interval. Then, the ink droplets are charged separately when they pass the charging electrode, and the amount of electricity charged by the central processing unit CPU Control; and then check whether the actual charge and phase of the ink drop are correct through the detection electrode; finally, the charged ink drop is deflected in the deflection electric field formed by the deflection electrode, ejected from the nozzle, and hit different positions on the surface of the product to form the required Various characters, patterns and other logos. The uncharged ink drops are driven into the recovery tank and re-enter the ink circulation system inside the machine. This saves ink. Welcome to inquire and negotiate!
