Roaming in the dark night

Chapter 29 Ghosts
Yu Wenhao almost didn't need to ask Lao Yao what the result of the interview would be, the answer was already written on his face.

Seeing the frustration on Lao Yao's face, Yu Wenhao was also a little depressed. He thought that Lao Yao, a Ph. Being laid off doesn't count, and the resume is still dirty.

He is only a few years older than himself, only 42 years old, and he has already been recognized as an elderly person by the workplace, and every door is closed to him.What the fuck is wrong with this world, is there room for reasoning?Yu Wenhao didn't even know, but in a few years, when I reached Lao Yao's age, would I also encounter his embarrassment? By then, I would probably only be able to become a full-time online car-hailing driver.

If people in their forties, who are in their teens, drive online car-hailing, deliver food and express delivery, and work as security guards, what about older people in their 56s?Are there no more places for them in the workplace?Are we all energetically forced to retire?

The problem is that someone has to take care of you.

Yu Wenhao checked the time and said to Lao Yao:
"Old Yao, if you don't mind, how about going to our cafeteria for lunch?"

"Okay!" Lao Yao readily agreed.

The two went to the cafeteria for dinner, returned to Yu Wenhao's office, sat down and talked again, Yu Wenhao asked:

"Old Yao, would you like to rest on the sofa for a while?"

Lao Yao asked back: "It doesn't affect you, does it?"

Yu Wen said with a smile: "It doesn't matter. At this point in time, everyone is resting. What is the effect?"

Lao Yao said yes.

He picked up the windbreaker on the armrest of the sofa, loosened his tie, unbuttoned the top button, fell down, rested his head on the armrest of the sofa, covered himself with the windbreaker, and fell asleep soon caught.

Yu Wenhao looked at him and shook his head. He knew that although Lao Yao didn't go to work, he seemed to have nothing to do except for interviews, but in fact, he was more tired than when he was at work.My hands and feet are idle, and my brain is running 24 hours a day. Even when I sleep, I probably dream about looking for a job.

When a person is in this state, he will soon become tired, bored, and lose confidence in himself.

The sofa was occupied by Lao Yao, so Yu Wenhao could only sleep on the desk.But he doesn't care. Over the years, he has already practiced the magic of sleeping. He can fall asleep on any occasion. Even if he is standing, as long as he leans his back against the wall, he can still sleep beautifully for a few minutes.

Yu Wen seemed to wake up by timing. He was taking a nap in the office and didn't need an alarm clock. No matter what time he went to bed, when he woke up, it must be 01:30 in the afternoon, which happened to be the time for them to go to work.

He looked at Lao Yao, who was still soundly asleep, Yu Wenhao stood up, tiptoed out, and closed the office door by the way.

Yu Wenhao walked into the workshop, and the two printing machines were running. Yu Wenhao walked to the end of the Heidelberg SM74 four-color offset printing machine, looked at the finished products, and immediately yelled stop, and the whole machine stopped.

The supervisor of this machine ran over, looked at the finished product, and asked Yu, "What's the matter, Director Yu?"

Yu Wenhao pointed to the finished printed product, and said to the supervisor, "A ghost image is about to appear."

The supervisor got down on his knees to have a look, but he didn't see anything, so he picked up another finished product and held it in his hand to have a look. He asked Yu Wenhao, "No?"

"It will be available soon, within 5 minutes." Yu Wenhao said.

"Impossible." The supervisor looked at the finished product again and insisted, "I see no problem."

While the two were talking, other workers also gathered around, including the supervisor of the Speedmaster CD102 opposite, who also came over. Yu Wenhao felt that it was a good time to teach them. He said to the supervisor:
"Would you like to try it, I can't tell for 5 minutes."

Seeing what Yu Wenhao said, the supervisor was at a loss, and turned to ask the workers, "Do you think it's possible?"

Several workers looked at the finished product, stood by the supervisor, shook their heads and said it was impossible.

Yu Wenhao patted a worker on the shoulder, and said to him: "Go and start the machine, pay attention, stop as soon as you are told."

The worker said yes and ran to the console.

Ghosting is the most troublesome thing in printing. The so-called ghosting is the appearance of graphics and texts where they should not appear.

Ghosts are further divided into positive ghosts and negative ghosts. Yang ghosts refer to the positive patterns of printed matter, which form a shallow shadow shadow relative to the surrounding area behind the circumference of the printed matter, as if it were the positive pattern in front. The projection of the pattern.The negative image ghost refers to the negative image pattern of the printed matter, which forms a darker positive image shadow than the surrounding area behind its circumferential direction.

The formation of ghosts is very complicated, roughly divided into craft ghosts and mechanical ghosts.Process ghosting is not only caused by the design of the printed matter, but also caused by the chemical properties of the ink during the drying process, and the ventilation of the delivery section is not good, or the temperature in the workshop is too high or too low, hot and cold, etc. Both can cause ghosting.

Regardless of the mechanical ghosting, it is ultimately caused by the lack of ink in the ink roller.

When Yu Wenhao said that, everyone became interested, the machine started to run again, and the finished product came out in good condition. The supervisor looked at Yu Wenhao and smiled complacently. However, after laughing for less than 3 minutes, he immediately yelled:
"Stop, stop, stop!"

When everyone looked at the finished product again, ghost images really appeared.

"I really saw a ghost!" The supervisor looked at Yu Wenhao and asked, "Director, you are amazing. How did you do it?"

Yu Wen laughed and said, "Intuition."

"Intuition? No way?"

Yu Wenhao nodded and said, "It's really an intuition. If you have as many prints as I do, you will have this intuition."

Yu Wenhao didn't lie to the supervisor. He really relied on his intuition. When he looked at the finished product in front of him and felt very uncomfortable, he felt that a ghost was about to appear.Or sometimes when he listens to the sound of the machine and sees a tiny bubble, he immediately feels that something is wrong with the air circuit, and he must immediately stop the machine and check the air pipe and air valve of the cylinder.

Sometimes when I touch the finished product with my hands, I feel that the temperature is abnormal. Yu Wenhao immediately knows that the condenser is clogged, and the condenser must be cleaned immediately with an air compressor.

The printing machine runs at high speed, and more than 1 finished products are produced in one minute. Predicting equipment failures and troubleshooting them is the most reliable guarantee for printing companies like them to save resources and increase efficiency.Otherwise, once the finished product is completed, the waste caused will make this single work in vain.Customers spend money to buy your high-quality products, and the rate of good products is very low, so customers will not buy it.

The supervisor looked at Yu Wenhao, a little helpless, Yu Wenhao gave him a look, and said to him:
"Look at me, give me a wrench, and learn."

The supervisor said yes, ran away quickly, and brought gloves and a wrench to Yu Wenhao.

Yu Wenhao opened the protective cover on the transmission surface, let the printing machine run slowly, and loosened the nut when the reference shaft was at the lowest position.Wait for the printing machine to turn to another position, re-tighten the nut, so that the string ink roller has a slight movement.

Yu Wenhao turned around and said to the supervisor, "Okay."

The supervisor's eyes widened: "Is that all right? So simple?"

"Yes, it's that simple." Yu Wenhao said to the supervisor and also to the supervisor of Speedmaster CD102: "Have you learned anything? Turn it on."

The machine started to run again, and the ghost image disappeared after looking at the finished product.

"I've convinced you, I've convinced you!" the supervisor said to Yu Wenhao, giving her thumbs up.
