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

Liang Dongmei said: "It didn't take long for the factory to be my father's, making shoeboxes for Nanta, but I got married and separated, so my father supported it and gave us the factory, and he went out to work again." We didn't want to do shoeboxes and steal business with my dad, so we went to food packaging. ”

Chen Lei said: "Chairman Zhang, don't worry, the work will definitely be done well for you, and there is nothing wrong with the machine master." ”

Xiaowei asked, "What kind of machine are you?"

Chen Lei opened his mouth to speak, Liang Dongmei slapped him, and said with a smile: "We are half-open monochrome machine, 01, but we must be able to do a good job, and if you don't do a good job, you can't give money, right? ”

Xiaowei asked: "Is there blister molding?"

Liang Dongmei said: "There is blister, there is ABC for ridges, 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 print it is definitely cheaper than you, I can give you the original price." ”

Xiaowei said: "We have a lot of light printing things, all kinds of forms, notes, envelopes, double-linked and triple-out lists, and so on. ”

Liang Dongmei said: "The more the price, the better to say, we are among our peers to print a very low price, Zhang Dong, you can rest assured, I will definitely not add money, if there is a problem with the quality, you can find me." It's certainly no worse than Xinhua. ”

Xinhua Printing is the largest printing factory in all parts of the country, the printing press is German, it can be said that it is the boss of the domestic printing industry, is the designated production unit of newspapers, publications and books around the country, and all kinds of printed matter of government units are printed here.

However, as the boss, he also has his common problems, the price is high and the time is long. There's so much work to be numbered.

Private printing enterprises appeared one after another in the early 90s, the disadvantage is that the factory is small, the machine is poor, the advantage is that the price is flexible, the work is fast.

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

Offset printing is further divided into light printing and ordinary printing. The single newspaper printing form is light printing, because the paper is thin, the pressure cannot be too great, and only monochrome and simple pattern lines can be printed. The rest of what we see is ordinary printing, advertising leaflets, color paper bags, packaging boxes, and so on.

Gravure printing is generally printed 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 on the surface of the metal round roller in chrome, very delicate, bump on the waste.

They have the advantage of being able to print in an infinite loop, with no limit on the length of the printed product.

Toppan printing products such as books and newspapers.

The plate-making of offset printing is similar to that of photographic filming, which requires exposure and development, and the cost is lower than that of the concave and convex two, and the color pattern is much finer, but there are requirements for the size of the printed material, which is divided into full open, semi-open, four open and eight boot and even sixteen boots.

The machine has monochrome, two-color, four-color and five-color, and now there are six-color, seven-color and even 10+N colors, and the human eye is basically unable to distinguish between them.

The basic printing is ternary color plus black, that is, the four-color machine, also called the full-color machine, and we only have these four colors when we draw on the computer.

More than four colors of the printing machine is called spot color printing, that is, to add a blended specified color, no longer rely 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 and green, etc., and can also add fluorescence or coating to make the product more vivid.

01 machine is the lowest grade offset printing machine, but also the most common machine in China, monochrome manual paper, printing speed is slow, about three to five seconds a piece, if you want to use this machine to print pictures, you need to repeat the overprint four or five times, completely depends on the master's craftsmanship, because the overprint is easy to paste, there is ghosting.

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

Two-color, four-color, five-color is to add seats, which is equivalent to lining up several 08 machines in a row, this side automatically feeds the paper, and then the paper finally becomes a finished product through a row of printing rollers, so the machine occupies a lot of space, generally the five-color machine is more than ten meters long, and the space needs to be at least 16 meters, and the ground must be horizontal, 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 calculated in seconds, and the machine is dozens of sheets when it is turned on and off. All printing if the printing volume is small, the start-up fee will be charged, and the better the machine, the higher the start-up cost, because it is too fast and the loss is too great.

For example, before the official printing, it is necessary to position the trial printing, and the 01 machine can get more than 10 sheets of paper, and the five-color machine may need more than 100 sheets.

The good printing presses are all imported, and the more common ones in China are Japanese goods, such as Roland. The best is Heidelberg, Germany, and there is no dispute about this one. The printing technology we invented has been carried forward by others. There's a joke in the printing industry: we use Heidelberg.

In 01, digital printing technology began to appear, and the representative is Kyocera of Japan. Digital technology can even print single sheets, but it cannot replace traditional offset printing, its printing speed is not enough, but it greatly reduces the comprehensive cost of printing, such as the cost of proofing.

There is also a technology called screen printing in printing, the cost is low and the technology is easy to learn, and there is no requirement for the workshop, the disadvantage is that the printing speed is slow, although there is now a fully automatic screen printing machine, but the printing speed is still very slow, which is determined by the ink of screen printing.

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

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

In the Tang Dynasty, China began to use silk screen technology to print patterns on clothes, which is not the current technology.

The key to all printing technology is plate making, which will not be discussed in detail here.

Xiaowei said: "You know the birthday cake, right? We have to make our public packaging, and we have to print a special edition, as well as handbags, food boxes, birthday hats, knives and forks, can you make it? There are also bread packaging, moon cake boxes, bags, there are still a lot of things, I'm afraid you can't do it." How big is your factory?"

Liang Dongmei said: "We have three 01s, shell presses, paper cutters, all of which are fully equipped, and we can do it ourselves in plate making and design." ”

Xiaowei smiled and said: "Actually, I like to deal with private dealers, easy to communicate and flexible, but I really don't have confidence in you." How did you get in touch with us to make bags, just for the Mid-Autumn Festival, right?"

Liang Dongmei's face was a little red, and she said, "Your work is for another factory, and he can't get rid of it, so he takes it to our side to do it." There's your phone number up there, so I'm looking for it. It's normal for us to do this, and everyone is doing each other's work. ”
