Water-based indoor color lasts for 2 years, and outdoor color lasts for about 2 months, depending on the bursting degree of the sun!

At present, the machines that can print water-based ink are divided into foaming type and piezoelectric type. Foaming machine has a higher market share and cheaper price, but there are many channels in inkjet printing and the ink particles are thicker. Foaming machines can never print oily ink.

Piezoelectric machines can be water-based. If you want oil, you must have a special oil-pressure electric outdoor photo machine. Machines are more expensive than water! The specific description is complicated and difficult to explain. If you need to know more, please click my name, and I can find me in my information.
