Why UV printheads easy to clog?

Compared to other types of wide-format printers, UV printers' heads are more likely to get clogged/ blocked by the characteristic of UV ink. Many customers are upset about printhead clogged due to the expensive head price and time-consuming. That’s why we write this. 

Printer nozzle Clogged Reasons: 

All in all, the printer head clogging happens for two main reasons:

Ink sedimentation: 

The ink that is used has poor quality or out of date. When the printer is idle for a long time, lack of maintenance.

Ink drying:

The users take improper maintenance, not follow the user manual request. The printers are exposed to strong sunlight environment for a long time.

Printhead clogged risk:

UV ink: White Ink, Varnish, Color Inks (CMYKLcLm)

The main component of white ink is titanium dioxide, which easily causes sediments in a long time static state.

Compared with color inks and clear ink( varnish), more likely blocked nozzles. And the varnish is virtually a combination of resins, solvents, and resins, or oils and solvents, featuring larger particles than UV inks. So that it easily blocked printhead, especially for small droplet size Epson printhead, this is why most UV printers seldom use Epson print heads.
