Make sure the print head exhaust completely, and no bubble remains in it.
Adjust voltage and negative pressure of print head. A higher print head voltage can
improve the accuracy and color saturation of ink droplets, but it can cause the ink
outflow to be frequently broken as well.
Ink Use Guidelines
1. Very Important: Prevent ink or any part of ink route from contacting water or any
solution containing water molecules, otherwise, gel may be produced, blocking
ink route or even print head.
2. Safety instructions:
Some chemical substances contained in ink are of very low toxicity and irritation, which
will irritate eyes and respiratory system and cause allergic reaction. Contact with ink can
be effectively reduced with sound ventilating device and personal protective devices.
When dealing with ink, acrylic gloves and work clothes should be worn. If ink spills onto
the skin, it should be washed immediately with soap-suds.
Eating, drinking and smoking are forbidden in the workspace.
3. Storage of ink:
Ink should be stored in sealed containers and placed in a cool, dry place with good
ventilation, free from exposure to strong light, with the proper storage temperature of
10℃ to 40℃. Though ink has the storage duration of 12 months, it is recommended to
use it up within 3 months. Pay attention to the production date when using ink. The
expired ink shall never be used. Because temperature has a great effect on viscosity of
ink, during change of seasons the different viscosity of ink may affect printing effect,
especially between winter and summer. In addition, ink manufacturers may adjust the
viscosity of ink according to change of seasons, hence you should select ink as per
actual ambient temperature.
