UV curing from the physical point of view of the sub surface curing, the inner layer curing, deep curing, complete cure. So in the use of UV ink, be sure to fully mixing ink before use must be fully stirred is the basic principle of the use of ink. This is because the ink in the resin, solvents, pigments, additives, the proportion of different ink placed after a period of time, there will be a phenomenon of stratification. Components such as before using not stir, the proportion of light in the upper, than the major composition of precipitation, so that there will be customers often respond to the ink quality is not stable, before and after the use of ink covering power, adhesion of different phenomena.

And due to UV ink for UV light solid ink, and sunlight contains ultraviolet radiation, it is suggested that the UV ink printing workshop indoor sunshine light shoulds not be too bright, such as the light is too bright workshop please may wish to install curtains to block the light, such as indoor have more daylight lamp printing workshop, please note meaning fluorescent lamp appearance of silver shedding caused by ultraviolet (UV) transmission phenomenon, indoor light is too strong and fluorescent UV transmission phenomenon will cause UV ink in the printing process on the screen solidified, which blocked the screen.

This is the printing enterprises in the use of UV curing ink to pay attention to the place, but too much UV ink how to store it?

Under normal circumstances, UV ink at the dark interior 22 DEG C to 25 C ambient unopened cans storage time for 1 year and a half to two years, can please tighten the cap stored in 22 DEG C to 25 C ambient storage time for half a year, please pay attention to the ink can not to allow water to spill into the bottle. UV ink and light reactive UV printing ink should avoid direct sunlight, do not close to the fluorescent lamp and mercury lamp etc..

But in storage, pay special attention to the following questions:

1 safety first, when storing ink as far as possible away from fire, heat source, in case of accident.

2 ink warehouse is best to maintain constant temperature, and the temperature difference between the printing shop can not be too wide. If the difference between the two is larger, the ink should be put into the printing shop in advance, not only conducive to the stability of the ink performance, but also to ensure the production of high efficiency.

3 in some parts of the north, the winter is relatively cold, should avoid the ink stored in the outdoor, to prevent the ink at low temperature. In case of gel, it will be transferred to the high temperature of the Treasury, or put into hot water, so that the recovery of insoluble material.

4 in the ink storage and management should follow the "first in first out" principle, that is, the first purchase of the first use of the ink to prevent ink due to the storage time is too long to affect its use

5 ink also has a certain shelf life, if stored for too long, the ink in a variety of ingredients will occur separation, precipitation phenomenon. Therefore, the ink is not suitable for long-term preservation, the general preservation period to 1 years is appropriate.

6 after printing the remaining ink must be sealed in a dark place, before re use must be filtered with more than 100 mesh filtering, full mixing and then mixed with the new ink.

In addition, special attention should be paid to the stability of the storage. Avoid the factors that can affect the stability of the. This can be a reference to the influence of UV curing ink stability of several factors in the text, but we must remember that different manufacturers of UV ink mixed use will also cause the change of UV ink stability. Therefore, when the ink needs to be mixed, the test must be done before any reaction can be mixed use.
