How does the UV digital printer select the number of print heads? Usually when customers consult products, UV printer manufacturers will ask that how many print heads and colors do you need? So what is the number of this nozzle based on? There are several reasons for this:
1. Manufacturer's technical level
The technical level of UV inkjet printer manufacturers has a very large impact. Some manufacturers can do six-color equipment, some manufacturers can do eight-color equipment, and some manufacturers can do nine-color equipment. When customers choose UV printers, they must know the situation in advance to avoid the initial purchase of four-color UV printers. If they need to upgrade later, they will not be able to achieve them.
2. Process requirements
It mainly refers to whether the digital UV printer print pattern needs embossing effect. If necessary, it needs a nozzle to print white ink. Whether you need to print varnish, if necessary, you need to add one more nozzle. Do you need a faster print mode, such as dual four colors, double six colors, and so on.
3. Characteristics of the nozzle
Different nozzle characteristics are different. Some nozzles can produce eight colors (Epson DX5), and some nozzles have one color (Seiko gs508), and some nozzles have one head, two colors (Ricoh Gen5), then according to the standard 4 color requirements, 1 Epson nozzle uv printer is enough, 4 Seiko gs508 nozzles, 2 Ricoh 5 nozzles.
These factors directly affect the number of UV printer nozzles. Of course, when we choose, the first consideration is that the equipment must meet the requirements of capital budget, material printing speed, printing quality, and then consider the corresponding consumables cost. Finally, we must also think about the cost of after-sales maintenance and other factors.
