What is the reason for the fading phenomenon of handbag printing ink？After the

handbag printing was placed at the customer's place for a period of time, the ink color

gradually changed,but the same phenomenon did not occur in the previous batches of

products. This situation is generally caused by the use of expired ink. The shelf life of

ordinary uv inks is usually one year, and the use of expired inks is easy to cause

discoloration of label products. Therefore, when using uv ink, the printing factory must

pay attention to the use of ink produced by regular manufacturers,and pay attention to

the shelf life of the ink, and timely update the inventory to avoid using expired ink.

What is the reason for the fading phenomenon of handbag printing ink？In addition,

pay attention to the amount of ink additives used in the production process of handbag

printing. If the ink additives are used excessively, the color of the ink after printing may

also change. Therefore, when using various ink additives, it is better to communicate with

the ink supplier first, and then determine the correct proportion range of additives.

In the production process of handbag printing, spot color inks are often required to be

prepared. Many printing plants have a far cry from the color of the sample when preparing

spot color inks. The main reason for this kind of situation is that the ink ratio is not correct.

What is the reason for the fading phenomenon of handbag printing ink？Spot color inks

are prepared from a variety of primary color inks, and most uv inks are color pass color

systems, so spot color inks are often prepared according to the proportion given on

the color card of color pass. However, it should be pointed out here that the ink ratio on

the color card of Caitong may not be completely accurate, and there are often minor differences.

At this time, there is a certain requirement for the experience of printing personnel, because

the sensitivity of printing personnel to ink color is very important. Printing personnel should

learn more and practice more, and accumulate experience in this field continuously to

reach the level of proficiency.
