9. How to compare the color of thermal transfer paper or heat transfer film?
a When comparing the color of a thermal transfer paper or a thermal transfer film, select the same sample with the same position and the same position. Use the same transfer conditions and transfer the same substrate to the same color. The method of comparison may be inaccurate due to the direct use of the non-transferred paper sample or film surface color for comparison.
b When selecting the substrate for colorimetric platens, try to match the base color of the substrate used in large scale production.
10. Does heat transfer change the original characteristics of the substrate?
a The products with decorative texture processed by thermal transfer will not change the original luster, abrasion resistance, weather resistance, and acid and alkali resistance of the products due to thermal transfer. Decorative effect.
bThe surface treatment of the transferred substrate is very important, such as smoothness, gloss, color, etc., will directly affect the surface effect after the substrate is transferred. If the surface of the transferred substrate is a high gloss surface, transfer After the product is also high light.
11. What is the cause of poor paper removal or film release after thermal transfer?
The woodgrain thermal transfer paper and PET thermal transfer film produced by the company have taken into account the user's convenience in the process of paper stripping or stripping. If the paper is still not properly stripped or stripped, the possible causes are:
a The surface of the transferred substrate has quality problems such as high temperature resistance, sticky paper or mucous membranes, etc.
b After dusting, the dust layer on the surface of the transferred substrate is not completely cured, resulting in re-solidification during thermal transfer.
c If the thermal transfer glue is used, the quality of the thermal transfer glue, the ratio of concentration and the amount of brushing will directly affect the release of paper.
d If a thermal transfer glue is used, it is recommended that a suitable release agent (also called silicone oil) be added to the thermal transfer glue to solve the problem of poor paper removal.
12. After heat transfer, why is the thermal transfer paper or heat transfer film fragile or zooming?
Usually, the temperature of the transfer baking is too high or the time is too long, resulting in excessive aging of the thermal transfer paper or the thermal transfer film.
13. Why does the same thermal transfer paper or thermal transfer film produce the color difference of the transferred product?
When colorimetrically, the colorimetric conditions of “selecting the same texture, comparing the same position, using the same transfer conditions, transferring the substrate to the same background color, and comparing under the same light source†are not observed.
b The transfer substrate has a color difference.
c The performance of the transfer equipment is unstable.
d During the thermal transfer process, the transfer temperature and time are not controlled. Usually, the transfer temperature is between 120°C and 190°C. The transfer temperature and time are directly proportional to the color of the transferred texture. Otherwise, it is lower than At a transfer temperature of 120° C., no transfer is possible; at a transfer temperature of 190° C., the color of the texture transferred to the substrate is gradually lightened with the passage of time.

14. After the transfer, the product surface color is not uniform or deep and shallow What is the reason?
a The surface of the transfer paper or transfer film that is in contact with the substrate is not tightly attached or insufficient. If baking is performed, the transfer paper is curled up, or when the vacuum is applied, the tubular bag may leak.
b The temperature in different positions in the oven is not the same or uneven.
When the substrate is put into the oven, different locations are not put into the box at the same time, resulting in a long time for the part of the substrate to be transferred with respect to other parts.
d When the company sculpts the printing plate roller, it intends to produce a deep and shallow texture. Therefore, customers must pay attention to the original style of the printing plate roller when selecting the printing plate.
