The analysis is as follows:

1, how many times do you suck the ink on the printing surface with a paper towel, so that the whole printing surface can't absorb oil at all.

2, the color of the word cover is so light that it can hardly be seen. At this time, gently wipe the original light-colored place of the seal with a paper towel a few times, and then turn the photosensitive seal over.

3. Literally drop some special oil for photosensitive seal (it must be special oil for photosensitive seal) and put it until the ink is completely absorbed. This step can be repeated several times. After adding, wipe off the excess ink on the surface with paper, and your seal will be ready.

Extended data

Photosensitive seal:

1. After laser printing, it is directly exposed on the photosensitive material, and then oiled for later use. The imprint is stable and can keep the original lines of the document. It is suitable for pattern seals, cartoon seals and signature seals, and can be used for tens of thousands of times. It is also a durable stamp-free seal, so it is also suitable for seals with large usage.

2. The supplementary ink of photosensitive seal must be the same brand as the original ink, otherwise the seal may be damaged due to improper use of ink.

3. In addition, the price of the seal material of the photosensitive seal machine is slightly higher than that of ordinary seal engraving, but the photosensitive seal is green, pollution-free and convenient to use, which can avoid the bondage of seal inkpad, but the demand for photosensitive seal oil is more practical.
