Firstly let us talking about the Inkjet Printer. Because of the technology of inject, the Inkjet Printer can be divided into two parts. HP, ENCAD, CANON each adopts “Evaporation Vesicle” inject tech. PH is the inventor of thermal bubble, the print tech of thermal bubble is finished by heating print heads of heating elements to make the inner ink vaporizing and bubble expanding, the pressure from it is that using ink to squeeze out “jet mouth”, and forming the ink droplets that spray to print media. By the color layer technology , it efficiently improved the printer resolution, at the same time, it can achieved more than 200 different kinds in the each ink pots.
But the ESPON, ROLAND which from Japan, MIMAKI, and MUTOH all adopt the micro-pressure electronic jet technology. At the same time, JetExpress technology takes the high inject printing. “micro-piezo” printing technology is invented by EPSON, which used the piezo crystal to produce telescopic deformation characteristics under the two ends changeable voltage. By using driving electric signal, touching piezo crystal working on the inner ink to force it spur out ink. Micro piezo electric technology can achieve high precision printing in its outstanding, by taking the neutral oil ink, the waterproof function can reduce the process of overcapping, it can make the outdoor pictures more precise. Piezo electric technology is mainly used in more than 2 meters width of large print machine, due to the usable of eco-solvent, it can be used directly on ordinary light cloth, so it can be the first choice of outdoor making. Generally speaking, the lifespan of Piezoelectric ink-jet printing head is long, but the single print head cost is high, the lifespan of foaming ink head is short, but the cost is relevantly low; from the printing quality, the picture printed by piezo electronic is more real, the picture printed out by evaporation vesicle printer is more colorful.
Now we talk about the main references about the printer:
Nozzle: divided into hot foaming sprayer and two kind of micro piezoelectric nozzle, because it is a pictorial machine's main parts, so we will discuss it later.
Width: most of the effective width of pictorial machine on the market mainly focus on 130 cm (50 inches) and 152 cm (60 inches), and 160 cm (64 inches), and 160 cm (74 inches), with 160 cm machine is most sensitive to the market. At present, the domestic material standard specifications are as follows: 0.914 meters, 1.06 meters, 1.27 meters, 1.06 meters, 1.27 meters of the following picture is in the majority. Width points into the paper width (also known as the material width) and spray width (width), the former tend to be more than 1 inch (2.54 cm).In fact, in the aspect of advertising, most clients are using 360PI, 540DPI, 8PASS, which were the best output models. You need to use the original material until you find some small details. Sometimes, the printer quality is not obviously can be seen as good enough, the speed of printing reduced, in the most situation, the print head was ruined so badly, if you add the cost this time, it is really not a good way .according to our company’s idea, except that exam the machine before purchasing , 95% clients maybe never to make map to give other customers, Currently EPSON fourth-generation nozzle 1440 * 1440 dpi, the highest precision just become a kind of advocate by some dealers.
The output speed: the advocate speed by the dealer is not full of comparability, because it didn’t tell the specific test condition and the situation, some dealers will tell the “draft model” “photo model” and so on, but the customer maybe didn’t understand the meaning of it. There are some factors that affect the inkjet speed: A: equipment pure inkjet speed. B: software RIP speed C: data transmission speed and single, double ways, times of over inkjet. At present, the market that are selling main models are MIMAKI, ROLAND, MUTOH, which are in the same drying time. Pure inkjet speed is related to the model, mainly factors are: specification, PASS number, generally the accuracy is 14-28 sq. In fact, the inkjet speed of machine itself, the advantage and disadvantage of using the ink, and the temperature environment, humidity that all directly infect the good quality speed of long quickly speed output. On the same model, the speed that dealers advocate, in fact, during the inkjet, the highest accuracy is 3-4 sq/hour, at this point, it can be defined by long term machine to print more than 4 meters photos, after all, the machine can work for long years after you purchasing it. On the market of profiteering era, as making quotation flow type landslide, profit space is compressed, the advertising industry already reluctantly agree with such a fact that on the premise of satisfying practical precision, production speed, loss cost and stability of equipment has become the key to profit.
Material cost: the direct cost of the inkjet is mainly come from the ink, material, the using lever of print nozzle, laminating and scrap rate and so on, we always refer to the sum of the first four items about the material cost.Because the material tend to use universally. HP,ENCAD, the print head need to change.
