Possible problems and solutions of hot stamping technology

We have said before, hot stamping is the use of hot pressure transfer principle, the aluminum layer transfer to the surface of the substrate. That is, at a certain temperature and pressure, the aluminum layer will be peeled off from the base layer, and the aluminum layer will be stuck to the hot stamping material.

Let's take a look at a example of product that use hot stamping. The hot stamping process in the powder compact box below is more successful, and the content of hot stamping is clear and clean.

Sometimes the shower gel bottle or hand wash bottle we use, the font is blurred. There may be some problems in the process of hot stamping. For some lipsticks tube or lip gloss tube, we have used them for a long time, and the gold color on the outside package will fall off, which is also not done well in the hot stamping process.

Do you know what problems will be encountered in this process? Today, we will talk about the causes and solutions of common problems in the process of hot stamping. Let's have a look at the most common problems below and analyze, what will causes this problem, and how can we solve it?

Hot stamping cannot be completed or the printed pattern is blurred.

Cause:

a.The temperature of hot stamping is too low

b.The pressure of hot stamping is too small

c.The time of hot stamping is too short

d.The surface of the substrate is contaminated

e.The mold of hot stamping foil is wrong

f.The quality of hot stamping foil is poor or expired

g.The base color ink layer is too thick

h.The base color ink layer contains wax.

Solutions:

(1)Appropriately increase the temperature of hot stamping

(2)Turn up the pressure

(3)Extend the time of hot stamping

(4)Wipe the substrate surface with alcohol and other solvents

(5)Choose the model carefully

(6)Replace with good quality, not expired hot stamping foil

(7)Reduce the thickness of the base color ink layer,

(8)Replace the background ink.

In addition to the most common reasons mentioned above, also have some other problems.

a.Graphic content is dull

b.The color will be change after hot stamping

c.Hot stamping of the same material, but the effect sometims good and sometimes bad.

d.Use the same hot stamping verison, but the hot stamping effect is different

e.The Graphic content of hot stamping is incomplete, the edges are uneven and unclear.

f.Unstable and easy to fall off

From the basic process of hot stamping can be seen, the three basic elements of hot stamping are: temperature, pressure and time. In order to obtain the ideal hot stamping effect, hot stamping temperature, hot stamping pressure, hot stamping speed and other process parameters must be reasonably mastered; In addition, the quality of raw materials related to hot stamping must also be guaranteed, such as: the hot stamping suitability of substrate, the performance of foil materials and the quality of hot stamping version and so on. If a link out of the problem, will affect the final hot stamping effect. A perfect hot stamping effect, for cosmetic packaging products is very important, can make our cosmetics look more high-end.

Hot stamping equipment involves electricity, high temperature and mechanical action, so the staff should always pay attention to safe operation in the whole production.
