I am a screen printer. I have been doing this for five years. I am 21 years old this year. I often come into contact with industrial chemicals containing chemical substances such as tinna water, boiling oil water, screen washing water, and ink...

It is definitely poisonous and harmful to the body over a long period of time.

Screen printing refers to using a silk screen as a plate base and using a photosensitive plate making method to create a screen printing plate with graphics and text.

Screen printing consists of five major elements, screen printing plate, scraper, ink, printing table and substrate. Printing is carried out using the basic principle that the mesh of the graphic part of the screen printing plate can pass through the ink, but the mesh of the non-graphic part cannot pass the ink.

When printing, pour ink into one end of the screen printing plate, use a scraper to apply a certain amount of pressure on the ink part of the screen printing plate, and at the same time, move towards the other end of the screen printing plate at a constant speed while the ink is moving. The scraper is squeezed from the mesh of the graphic part onto the substrate.

It will not cause impotence and has no impact on reproductive organs. Absorbing too much ink will have some impact on the body's lungs. Nothing else.
