Chapter 945 Printing Industry

Xiaowei asked, "How long have you been doing this?"

Liang Dongmei said: "Not long ago, it turned out that the factory belonged to my dad, who made shoe boxes for Nanta, but I got married and split it up. My dad supported me and gave us the factory, and he went out to do heavy work again. We didn’t want to compete with my dad for shoebox business, so we went into food packaging.”

Chen Lei said: "Chairman Zhang, don't worry, the job will definitely be done for you, and the machine master is fine."

Xiaowei asked: "What kind of machine are you? What color?"

Chen Lei opened his mouth to speak, Liang Dongmei slapped him, and said with a smile: "We are half-turning on the monochrome machine, 01, but the work must be done well, and you can't pay if you don't do it well, right? We plan to expand As for the factory building, if we want to install an 08, we can’t afford even the most expensive machine.”

Xiaowei asked: "Is there any blister? Is there any light printing?"

Liang Dongmei said: "There are blisters, there are ridges and ABCs, there is no light printing, there is a factory that specializes in light printing, but I can help you find it, the price, we will definitely be cheaper than you when we go to print, I can give you the original price. "

Xiaowei said: "We print a lot of things lightly, such as various forms, memos, envelopes, double-page and triple-page inbound and outbound receipts."

Liang Dongmei said: "The more the price is, the easier it is to negotiate. Our peers will appoint a very low price. Don't worry, Mr. Zhang. I will definitely not add money. If there is any problem with the quality, you can come to me. It is definitely not worse than Xinhua."

Xinhua Printing is the largest printing factory all over the country. The printing machines are all made in Germany. It can be said that it is the leader of the domestic printing industry.

However, being the boss also has his common problems, the price is high and the time is long.There are too many jobs to be arranged.

Private printing companies emerged one after another in the early 90s. The disadvantages are small factories and poor machines. The advantages are flexible prices and fast scheduling.

There are several common types of printing, offset printing, gravure and letterpress.

Offset printing is divided into light printing and general printing.Printing forms and newspapers is light printing, because the paper is thin and the pressure cannot be too large, only monochrome and simple pattern lines can be printed.The rest we see is ordinary printing, advertising leaflets, colored paper bags, packaging boxes and so on.

Gravure printing is generally used to print plastic products. All kinds of plastic packaging we come into contact with are basically gravure products. It is the same as letterpress. The pattern is directly engraved in chrome on the surface of the metal round roller. It is very delicate and will be scrapped if it is touched.

Their advantage is that they can be printed endlessly without limiting the length of the printed product.

Letterpress printed products such as books, newspapers.

The plate making of offset printing is similar to that of photographic negative film. It needs exposure, development and fixation. The cost is lower than that of concave and convex. The color pattern is much finer, but there are requirements for the size of the printed material. On and eight boots to sixteen boots.

Machines have single-color, two-color, four-color and five-color, and now there are six-color, seven-color or even 10+N colors, which are basically indistinguishable to the naked eye.

The basic printing is three-color plus black, which is a four-color machine, also called a full-color machine. When we draw on the computer, we only use these four colors.

A printing machine with more than four colors is called spot color printing, which is to add a specified color that has been prepared, instead of relying on the automatic synthesis of the machine, so that the specified product color can be printed. 10+N is to add more than six kinds of spot colors, such as gold, silver, orange, green, etc., and fluorescent or coating can also be added to make the product more vivid.

Machine 01 is the lowest-end offset printing machine, and it is also the most common machine in China. It has a single-color manual loading, and the printing speed is relatively slow, about three to five seconds per sheet. If you want to use this machine to print photos, you need to repeat the overprinting four times. Or five times, it all depends on the craftsmanship of the master, because overprinting is easy to blur and double images appear.

The 08 machine is also monochrome, but it loads paper automatically, and the speed is much higher than that of the 01 machine, about one sheet per second or a little faster.

Two-color, four-color, and five-color are additional seats, which is equivalent to arranging several 08 machines in a row, where paper is automatically loaded, and then the paper passes through a row of printing rollers and finally becomes a finished product, so the machine takes up a lot of space. Generally, five-color machines have ten A few meters long, requires a space of at least 16 meters, and the ground must be level, the bearing capacity must reach three tons per square meter, and the indoor temperature and humidity have strict requirements.

The printing speed of such a machine is quite fast, and it can no longer be counted in seconds, and the printing speed of the machine is dozens of pages every time it is turned on and off.For all printing, if the printing volume is small, start-up fees will be charged. The better the machine, the higher the start-up fee, because the printing speed is too fast and the loss is too large.

For example, before the official printing, it is necessary to position and test the printing. The 01 machine can handle ten sheets of paper, and the five-color machine may need more than a few hundred sheets.

The good printing machines are all imported, and the more common ones in China are Japanese products, such as Roland.The best is Heidelberg, Germany, there is no dispute about this.The printing technique we invented was carried forward by others.There is a joke in the printing industry: we use Heidelberg.

Digital printing technology began to appear in 01, represented by Japan's Kyocera.Digital technology can even print on a single sheet, but it cannot replace traditional offset printing. Its printing speed is not enough, but it greatly reduces the overall cost of printing, such as the cost of proofing.

There is another technology in printing called screen printing, which is low-cost and easy to learn, and has no requirements for the workshop. The disadvantage is that the printing speed is slow. Although there are fully automatic screen printing machines, the printing speed is still very slow. This is Determined by screen printing ink.

But the application of screen printing is quite wide. It can print everything, cloth, paper, metal, glass, plastic, and it can be flat, three-dimensional, or arc-shaped. There are overlay printing, three-dimensional printing, etching printing, and foaming printing. There are many effects and characteristics such as drawing and silk printing.

Many things in our lives are printed in this way, such as clothing, cups, tables, chairs, shoes, hats, electrical appliances and so on.The biggest feature is that it is easy to operate, one person can make it at home, there is no requirement for the site, and even the tools can be made by yourself.

my country has already started printing patterns on clothes with silk screen technology in the Tang Dynasty, which is not the current technology.

The key to all printing technologies is plate making, so I won't go into details here.

Xiaowei said: "Do you know about birthday cakes? We have to make our public version packaging, and we also need to print a special version, as well as handbags, food boxes, birthday hats, knives and forks, can you do it? There are also bread packaging, moon cake boxes , carrying bags, there are still a lot of things, I’m afraid you won’t be able to make them. How big is your factory?”

Liang Dongmei said: "We have three sets of 01, all of which are fully equipped with shell pressing machines and paper cutters, and we can do the plate making and design ourselves."

Xiaowei smiled and said: "Actually, I really like dealing with private businesses. I am easy to communicate and flexible, but I really have no confidence in you. How did you get in touch to make bags for us? The Mid-Autumn Festival is Bar?"

Liang Dongmei blushed a little, and said: "Your job was given to another factory, and he couldn't get it out, so we got it to do it here. There is your phone number on it, so I found it. We are the ones who do this. It's normal, everyone arranges work for each other."
