seal shell, photosensitive seal pad, photosensitive printing oil, sulfuric acid paper/printing film, and exposure film.

photosensitive seal making system:

photosensitive seal machine, computer, seal typesetting software, laser printer (inkjet printer can be used, and the effect is not as good as that of laser printer)

photosensitive seal making process:

1) Print the prepared sample on sulfuric acid paper with laser printer.

2) cover the transparent exposure film according to the specifications of the sample, and its size shall be subject to completely covering the sample.

3) The order and orientation among the printed sample, the exposure film and the photosensitive seal pad are as follows: the printed sample is at the bottom layer, close to the glass plate of the photosensitive machine, with the printing surface facing upwards, the middle layer is the exposure film, and the third layer is the seal pad. The three are in smooth and close contact in turn, and no gap folds are allowed in the middle. Cover the light shield of the photosensitive machine and pull the handle to press it tightly.

4) Turn on the power supply and turn on the power switch, and the photosensitive machine will start charging.

5) There are many kinds of photosensitive seal pads, and different seal pads need different exposure energy. In order to accurately expose all photosensitive seal pads, this machine adopts the exposure mode that can display free random exposure according to voltmeter. The exposure voltage ranges from 16V to 32V, which can be exposed. (When using for the first time, users are advised to test the best exposure voltage value suitable for this chapter pad with leftover materials. For example, for some domestic photosensitive pads, the exposure voltage is 28V+5% for sulfuric acid paper print and 26V+5% for film print). When the photosensitive machine charging indicator reaches the required exposure voltage of the chapter pad, turn off the power supply and press the trigger button to complete the exposure.

6) Take the exposure box out of the machine, open the exposure box, take out the exposed chapter pad, and remove the sulfuric acid paper/printing film and exposure film.

7) Put the exposed pad into the corresponding seal shell, and use AB glue to make the seal shell of the pad firm.

8) Inject scalar printing oil according to the seal specifications, and after the printing oil is absorbed and evenly distributed, it can be delivered to customers.
