Test method for transfer rate of thermal sublimation transfer paper

Abstract

A method for testing the transfer rate of sublimation transfer paper is disclosed. First, a roll containing finished thermal transfer paper is mounted on a detection mechanism and weighed to record its weight, M1. The finished thermal transfer paper is then unwound and, during the unwinding process, a pattern on the finished thermal transfer paper is transferred. Finally, the finished thermal transfer paper, after transfer, is rewound on the detection mechanism and weighed to record its weight, M2. The transfer rate, η, is calculated as (M2-M1) / (M1*a), where a represents the ink content of the finished thermal transfer paper. This method facilitates a convenient testing process and facilitates accurate and intuitive quality assessment of sublimation transfer paper.

Description

Technical Field

[0001] The invention relates to a testing method, in particular to a method for testing the ink transfer rate of thermal sublimation transfer paper, and belongs to the technical field of thermal sublimation transfer paper production. Background Art

[0002] Sublimation transfer printing involves mirror-printing images such as portraits, landscapes, and text onto sublimation transfer inkjet paper using an inkjet printer loaded with sublimation transfer ink. The paper is then heated to approximately 200°C, causing the ink to sublime and penetrate the substrate, resulting in a lifelike transfer of the color image from the paper onto materials such as textiles, porcelain cups, plates, tiles, and metal. Sublimation transfer produces vibrant, rich colors, comparable to printing. Sublimation transfer involves sublimating the ink at high temperatures, penetrating the substrate, and forming a vibrant image. Therefore, sublimation products are durable and resist peeling, cracking, or fading.

[0003] Transfer rate is a basic performance of transfer paper. People will judge the quality of transfer paper based on its transfer rate. A high transfer rate can make the color of the transferred object more vivid, indicating that the quality of the transfer paper is higher. Currently, companies test the transfer rate by comparing the whiteness of the transfer paper before and after the transfer of a specified ink color under standard transfer conditions. This is not intuitive and it is difficult to accurately and intuitively help people get the transfer rate, making it inconvenient to judge the quality of sublimation transfer paper. For this reason, a transfer rate test method for sublimation transfer paper is proposed to distinguish the transfer rate of sublimation transfer paper through a numerical transfer rate standard.

The ink content of a certain type of finished thermal transfer paper is a fixed value during production, and the ratio is a known quantity. Thus, the amount of ink successfully transferred is obtained by the difference between the two masses, and the actual ink transfer rate is obtained by dividing the difference by the total amount of ink.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-7 , the present invention provides a technical solution:

[0027] A method for testing the transfer rate of thermal sublimation transfer paper includes inserting a finished transfer paper roll 8 onto the outer wall of a fixed column 7, and rotating a threaded rod 12 clockwise to move the threaded rod 12 toward the vertical plate 6. The movement of the threaded rod 12 drives a movable seat 13 to move, and the movable seat 13 pushes a connecting rod 14. The connecting rod 14 pushes a clamping plate 11 outward. The clamping plate 11 can clamp the transfer paper roll 8 to prevent the transfer paper roll 8 from shifting during the subsequent weighing process, which would affect the accuracy of the weighing.

[0028] Subsequently, the weight detector 2 is turned on to detect the weight of the transfer paper roll 8 and record it. The threaded rod 12 is rotated counterclockwise to drive the movable seat 13 to move away from the vertical plate 6. The movable seat 13 pulls the connecting rod 14, and the connecting rod 14 pulls the clamping plate 11 back into the cavity 9, thereby releasing the lock on the transfer paper roll 8 and removing the transfer paper roll 8.

[0029] Next, after performing thermal sublimation transfer on the transfer paper roll 8, repeat the above steps to re-measure the weight of the transfer paper roll 8;

[0030] Finally, by comparing the two measured weight data, the weight of the ink that has penetrated into the transferred object can be obtained, thereby detecting the transfer rate of the transfer paper roll 8. The detection process is convenient and is conducive to accurately and intuitively detecting the quality of the thermal sublimation transfer paper.

[0031] At the same time, when the weight detector 2 is not working, the extension of one end of the piston rod of the electric cylinder 18 can drive the slide plate 17 to move upward. The upward movement of the slide plate 17 can drive the connecting column 19 and the hook 20 to move upward. The hook 20 lifts the lifting ring 21 and the fixed plate 4, reducing the pressure on the weight detector 2, effectively protecting the weight detector 2, and improving the service life of the weight detector 2.

The outer wall of the transfer paper roll 8 is moved by rotating the threaded rod 12 clockwise to move the threaded rod 12 toward the direction close to the vertical plate 6. The movement of the threaded rod 12 drives the movable seat 13 to move. The movable seat 13 pushes the connecting rod 14. The connecting rod 14 pushes the card plate 11 to move outward. The card plate 11 can clamp the transfer paper roll 8 to prevent the transfer paper roll 8 from shifting in position during the subsequent weighing process and affecting the accuracy of weighing. At this time, the weight detector 2 can be turned on to detect the weight of the transfer paper roll 8 and record it. By rotating the threaded rod 12 counterclockwise, the threaded rod 12 can drive the movable seat 13 to move. 13 moves in the direction away from the vertical plate 6, the movable seat 13 pulls the connecting rod 14, and the connecting rod 14 pulls the card plate 11 back into the cavity 9, releasing the lock on the transfer paper roll 8, and taking the transfer paper roll 8 off. After the transfer paper roll 8 is subjected to thermal sublimation transfer, the above steps are repeated to re-measure the weight of the transfer paper roll 8.
