What are the special requirements of uv ink application?Requirements for printing

equipment. Compared with ordinary ink, the application of uv ink has certain

requirements for printing equipment. For example, at present, many printing enterprises

implement uv printing by installing uv curing devices on ordinary offset printing machines,

but there are many problems in this equipment transformation method, such as strong

corrosivity of uv ink, which may lead to expansion of ordinary cots and blanket, affect

the stability of printing pressure, and even lead to peeling or surface fragmentation of

cots in serious cases. Therefore, uv ink printing has high requirements for cots and blanket,

and generally requires the use of cots and blanket dedicated to uv printing.

What are the special requirements of uv ink application?For the requirements of storage

conditions, the above mentioned uv ink curing problems and printing stability all need

an important prerequisite, that is, good ink storage conditions. According to experience,

the best storage temperature of uv ink should be controlled at 20~25 to avoid sunlight,

and the best relative humidity should be controlled at 55%~65%. The uv ink should be

stored in a sealed way to avoid dust mixing, and the uv ink storage warehouse should be able to

maintain constant temperature and humidity. At the same time, it should also be noted that

the uv ink storage warehouse should be far away from fire and heat sources to prevent accidents.

What are the special requirements of uv ink application?The storage and use management of

uv ink should also follow the principle of "first in, first out", that is, the uv ink purchased first

should be used first, so as to prevent the use quality of uv ink from being affected due to the

long storage time. The remaining uv ink after printing must be sealed and stored in a dark place.

uv ink should not be stored for a long time. It should be used before its shelf life. The longest

shelf life should not exceed one year. Otherwise, once the uv ink deteriorates,

it will not only affect the printing quality, but even cause printing failures in serious cases.
