First of all, a popular cleaning method on the Internet is actually very difficult to operate as a non-professional, and it is easy to break if you are not familiar with the seal structure. On the contrary, it is time-consuming and risky. Of course, whether it is effective or not is unknown.
Secondly, it is said that it needs to be re-carved. It is not ruled out that some seals are improperly made and used, and they need to be re-engraved with wrong oil. But this is definitely not absolute! Generally, there is no need to re-carve. The photosensitive seal is just a seal, and its name seems to be full of science and technology, but it is always a seal.
Let's get down to business. Our company used many new chapters in the early stage. Adding secondary oil (atomic oil) five months ago was not effective, but I didn't care because I didn't understand it. I added it again four days ago. Pay more attention to find it wrong. Then I also searched the information on the internet, and the answers basically made me desperate. The next day, I went to a lettering shop with the mentality of trying. The boss said that 50 yuan would help me repair it, and I would pick it up tomorrow, and then I would pay when I was satisfied. Considering that the application process for replica is rather troublesome, I decisively agreed. I got a good result the next day. A seemingly troublesome thing was solved in this way. Later, I chatted with my boss and learned that he also cleaned it, replaced a small part with anhydrous alcohol or something, and spent most of the time repairing it. Think about it, 50 yuan or remake, which is more cost-effective? Those so-called shops that let you re-carve are too lazy to clean you, mainly because they are too troublesome and can't make a few money. Why don't you carve a chapter quickly? In any case, they are not the people who apply to run the process.
I warn you again, basically those people in stationery stores don't know what a photosensitive seal is, atomic chapter. They will recommend you to buy atomic oil. If you add it wrong, you will be in trouble. The safest way to add photosensitive oil is to go to the local public security bureau to buy it. Although it is expensive, it is foolproof. Or go to a regular lettering shop authorized by the Public Security Bureau to buy photosensitive oil.
Hand-made, absolutely personal experience, I hope to help all the friends who are troubled by this.
