Because the principle of different types of machine nozzles is different, the ink used is also different. If the ink is selected incorrectly, the nozzle damage will be inevitable. At present, the ink can be roughly divided into:
One, DYE (indoor) dye-based thermal foam ink
Suitable for HP or NOVAJET indoor models, because the ink contains high foaming agent, after the ink head resistance heating, let the ink in a very short period of time to produce bubbles, and then squeeze the ink out, but in a long time high and low temperature Under the change, the ink chamber becomes lossy in the severe environmental changes of high heat and high pressure. Due to the successful development of alternative ink, the cost is lower, but the loss of the nozzle is an irreducible cost. General thermal foaming ink jet printers use inks that require between 70% and 90% moisture to keep the nozzles free from nozzles and heat. This means that sufficient time must be allowed for the ink to dry out on the media. Will spread out, so it installed more drying equipment on the machine, so as not to damage the screen.
Second, DYE (indoor) dye-based micro-pressure ink
Applies to the use of EPSON nozzle models, including the latest MIMAKI JV-4, MUTOH RJ-8000 and ROLAND FJ-500/600 series, piezoelectric nozzle is a piezoelectric crystal to hit and oscillate a fixed in the print head The diaphragm allows the ink in the print head to be ejected. Because it is "cold spray", the nozzle does not need regular replacement, but the early ink prices are higher, so the early indoor production costs are higher than the thermal foam, the recently launched MUTOH RJ-8000 series and MIMAKI JV4 series adopt the third generation of EPSON The nozzle, therefore, greatly improved the printing speed, and the micro-piezoelectric ink also dropped below 0.25 yuan/ml, so indoor production will use micro-piezoelectric as the mainstream model.
Third, PIGMENT (outdoor) pigment micro piezoelectric ink
Applicable to the use of EPSON nozzle models, including the latest MIMAKI JV-4, MUTOH RJ-8000 and ROLAND FJ-500/600 series, but due to the need to cover the film, and the production of outdoor processes is complex, high cost, and not become mainstream ink.
IV. Oil-based ink
Only applicable to MUTOH RJ-8000/RJ6000 and ROLAND FJ50/40/500/400 and MIMAKI JV2 series. Because of the limitations of micro-piezo nozzles, outdoor weathering is about 6 months, because the production of oily ink does not need to cover the film, and can Spray coating light box cloth, so widely used in indoor production and outdoor replacement frequently (about six months) in the area.
Fifth, solvent ink
Applicable to large-scale inkjet printers and the latest limit FY-6180, ink has a strong corrosive, can be directly infiltrated into the light box cloth and PVC material inside, so the nozzle is more demanding, the need for special solvent-type nozzles, and attached to the nozzle The equipment requirements are also high, so the solvent ink is not suitable for any sprayer of Japanese EPSON, and only the British XRRA and American company can produce the nozzle at present. Sai Angel, SALSA, Wit, and the latest limit FY-6180 all use such nozzles. And equipped with automatic ink filtration system, it is a professional outdoor production equipment, outdoor weathering guarantee up to two years.
