Screen Printing Column (44)

~Scary story of screen printing~

One night.
It happened when I was closing the factory with Mr. N after working overtime.
When I locked the door to the laboratory, turned off the lights, set the security at the entrance, and put the key through the terminal.
From around the laboratory where the door should have been locked, there is a "bang", the sound of closing the door...
 
When I asked Mr. N, "I heard something," he also said "it sounded like a door closing."

Me: "Anyone left?"
Mr. N: "We are the only ones left."
Me: "So that means..." "Mr. N, go take a look!"

Mr. N timidly went to the pitch-black laboratory again to confirm.
After a while, Mr. N with came back with a pale face.

Mr. N: "There was no one there!!"

We both felt a chill all over our bodies, but we locked the door tightly and went home.
The next day, I told the general affairs managers about what happened yesterday.

The general managers responded.
  "Don't be surprised by that. You're too timid."
  "It was nothing. You worry too much."
  "Something like that hasn't happened recently."
  "Don't worry, it hasn't appeared once in the last 10 years."

Me "What! That means...!!!!!"



Well, there are ghosts in the world of screen printing too.

When making screen stencils, if the stencil making fails, the emulsion may be peeled off and the emulsion may be applied again.
For example, if you make a mistake in the design and make a plate, it is a waste to throw away the plate, so the emulsion is removed and the gauze is reused. A ghost occurs at this time.
Strong ultraviolet rays are applied to the screen when it is exposed to light, which creates shadows of the pattern on the gauze.
Even if the emulsion is peeled off, this will remain like a shadow on the gauze.
 
If you print with a plate that has been remade using this gauze with shadows, the printed pattern will have shadows.
This is the ghost of screen printing.
If you look at the surface of the gauze, you can see a little colored shadow, but this seems to subtly affect the passage of ink.
If you want to make the print film thickness uniform, you need to pay close attention to the surface condition of the gauze.



So what happened 10 years ago...
I decided not to ask any more.
