Revise a law

Some of the short-lived texts are the most prone to shortcomings. Many of this phenomenon is not good for the original (ie, the film). Some words are slightly defective, such as re-spinning, reprinting, and changing the version, which will not only waste time, but also cause waste of media. In this regard, people are accustomed to looking for the "professionals" of the print edition to repair it. In fact, in this case, the machine personnel can handle it completely.

My treatment method is to find a steel piece and a needle. If the defect is linear, use a steel piece as a ruler, and use the needle to draw the desired line on the plate. If it is curved, use a needle to repair it directly. Afterwards, wipe the engine oil with your fingers from the camera body to detect the scratches (that is, the repair site), then apply a little ink from the ink roller to the scratches, and finally use a damp cloth to remove excess ink from the repair site. Wipe away, but note that the scratches should not be too deep and must be completed at one time.
