When printing the text version, due to the film itself or improper operation, it is easy to produce the phenomenon of dropping characters. When this happens, re-printing is a waste, and for general repair, the printing plate is not durable enough.
The author's experience is to use a small brush dipped in the PS version of the photosensitive solution to carefully fill in the missing parts. The printing plate that has been used on the machine should be removed and cleaned, dried and refilled, and then the printing plate is suspended and used a hair dryer Dry the filled area for about 15 minutes. After such processing, the printing plate generally has a printing resistance of about 30,000 prints, and if it is baked, the printing resistance can reach about 150,000 prints. Of course, if the number of prints is small, it can be filled directly with a ballpoint pen. This method is convenient and cost-effective, and the effect is also good.
