Summary Report on Practice III of 2020 Printing Factory

# Internship Report # Introduction Internship enables college students to increase their social experience and accumulate work experience. Social experience and work experience are decisive factors in the field of occupation. Only by participating in the internship and passing the inspection of the internship can we accumulate our own experience and experience. The following are three summary reports on the internship of 2020 Printing Factory, which I hope will be helpful to you.

Summary report on the practice of 2020 printing plant

At the request of the school, and in order to get exercise before entering the society, I went to xx packaging material factory in xx city for a five-week printing production internship. The factory is a small private printing and packaging enterprise, with less than 100 employees. The factory covers a small area, mainly engaged in printing, packaging, post-press processing and sales of products. The types of printing packaging materials are: cartons, cartons, paper bags, pvc bags, etc. Through more than one month's internship in Zhenlong Packaging Material Factory, I have a certain understanding of the production management of this enterprise. The printing department of packaging material factory includes business department, prepress studio, plate making department, production department, inspection department, technology department, post-press processing department and inspection department. The completion of a printed matter can not be separated from the cooperation of the above departments, and it is through the clear division of labor of each part that the whole printing process can be successfully completed. The production process of printed matter can be roughly divided into three parts: prepress, printing and post-press processing.

The first step is to process the graphic information of the source file to be printed, and then send it to the publishing department for typesetting. The typesetting operator will typeset according to the source files provided by customers and some requirements of customers. Typesetting needs to pay attention to the font size of words, the color of pictures, the location of bleeding and so on. These operations are all done by special software. After typesetting is completed, an electronic document with layout is obtained and handed over to inspectors for inspection. After the test results are correct, digital proofing can be carried out and the samples can be delivered to customers for confirmation. After the approval of the customer, the plate-making department carries out color separation and obtains the printing plate from the printer after imposition. In the whole process of plate making, operators should carefully check and communicate with typesetters in time to eliminate mistakes.

After the prepress process is completed, the next step is to send the printing plate to the printing workshop for printing, and the operators in the production workshop will control the printing machine to finish printing. Then the printed matter will be sent to the general inspection, checked and confirmed, then handed over to the post-press processing department for post-press processing, and finally delivered to the customer. At the beginning of a printing project, the process method and flow of the printing project are worked out through consultation with customers according to the requirements of customers and the characteristics of products, so it is necessary to fill in the Handover Sheet for Printed Materials and the Construction Sheet for Printing Production.

With the printed material handover sheet, the staff of each process can operate, while the printed production and construction sheet records all the information involved in the printing process in detail, so that the staff of each department can see the processes to be carried out at a glance. In the graphic studio of the factory, technicians process the graphic information of the source files given by customers, and then send them to the publishing department for typesetting, digitally proofing the typeset files, making them after approval by customers, and then sending them to the plate-making department. Also attached is a printed matter handover form and a printing production and construction sheet. The staff in the plate-making room will separate the color pages according to the requirements in the construction sheet, spell them into color pages, and then print them out by the printer to check the printed plates, such as

In addition to the traditional plate-making ps version, the printing factory can also make plates directly through ctp. After the plate maker completes the above work, he can fill in the complete report and sign it, and then send the plate to the production workshop for printing. After the prepress work is completed, the production department will make formal printing and production. The factory is small in scale and the production equipment is relatively simple. The printing presses in the workshop are mainly Beiren monochrome offset press, two-color offset press and a Heidelberg four-color offset press, which means that most of the operations are short-version work. Because the tasks received are not heavy, the workload is relatively small, and there are fewer staff in the workshop. Only the captain and assistant are responsible for each machine.

The captain's tasks are relatively more important, including inking, color matching, registration, ink supply adjustment, rule adjustment, flying up and down, machine control and so on. To ensure the normal operation of the printing press, as an assistant, he is engaged in simple and heavy work such as paper feeding, paper receiving, installation, disassembly, plate scrubbing, cylinder cleaning and so on. The printing process is complex, and every step and detail directly affect the quality of printed matter, so it must be particularly careful in the work of the production workshop. First of all, according to the content of the construction order, choose the type of ink needed, including color, viscosity, drying type, etc. , and then select the substrate, including newsprint, offset paper, coated paper, special paper, etc. In addition, the quality, format and quantity of the selected papers should be considered.

In printing, it is necessary to control the printing speed and pressure of the machine, which directly affect the quality of printed matter. If there is dirty plate and ink skin on the printing plate, it can be scrubbed with fountain solution. Printed products must be completely dry. If they are not completely dry, it is easy to cause the back to get dirty when stacked. In addition, in order to ensure the quality of printed matter, vertical air conditioners are installed in the production workshop to control humidity and temperature. After the production department finishes printing, the next step is to send the printed products to the inspection department. The so-called big inspection is to pick out the printed paper that has errors or does not meet the printing requirements. After the inspection, count the quantity and send it to the post-press processing department for post-press processing.

In the whole printing production process, every person in charge must fill in the production report of printing form after each process is completed, and the report carefully records the work situation in each time period and the data parameters of each printing process. According to the needs of products and customers, the post-press processing procedures are selected for products that have undergone major inspections, all of which are completed by the post-press processing department. The post-press processing department of the factory can complete the following processes: glazing, laminating, binding, die-cutting indentation, anodized concave-convex pressing and so on. Post-press processing can also be manually operated, such as imposition, pasting cartons, pasting protective paper, etc.

Through this internship, I have a deeper understanding of my major, and it is also the consolidation and application of what I have learned in school in recent years. Although I only practiced for five weeks, I learned a lot of practical knowledge during these five weeks. By participating in the production operation, I learned a lot of specific operation skills and mastered them skillfully. This knowledge is often something I seldom touch and pay attention to at school, but it is very important. During my internship, I broadened my horizons, increased my knowledge and realized the hardships and happiness of my work. More importantly, I have accumulated various experiences in my work and prepared myself for the future society. Through this internship, I found my own shortcomings and bad habits that should have been abandoned long ago.

The superficial knowledge and the lack of professional knowledge in practical application make me realize that I need to learn too much, and I also realize that I must master more knowledge and skills in order to occupy a place in today's highly competitive society. After more than a month's internship, I learned a lot and learned a lot. I still remember that at first, I didn't adjust my position and mentality.

I told myself to stick to it and not give up halfway. I realized that there are not many extraordinary things. If every ordinary thing is done well, it will be extraordinary. Therefore, seize this rare opportunity, study more and work harder, so that the knowledge you have learned truly belongs to you. Learning can not only rely on learning theoretical knowledge in the classroom, but also go out of the classroom, put into practice and go to the society to learn.

Because the outside world is infinite, there is a lot of valuable knowledge that books can't learn. Moreover, book knowledge comes from practice, and theoretical knowledge is a theoretical summary of experiencing life and work in practice. In addition, I also experienced the feeling of going to work. Although there are difficulties and blows during this period, it is the first step in life after all. I believe that as long as I persist and study hard, there will be a rainbow after the storm.

Chapter II Summary Report on the Practice of Printing Factory in 2020

The following are some summaries and experiences during my internship. I hope to learn from my own work and communication with customers in the future. First, the overall scale level of the factory.

Xxx printing plant is located in X mountain area of xx city, covering an area of 600 square meters and employing more than 60 people. With a manufacturing history of nearly ten years, he has developed into a professional-scale printing expert and is quite famous in the developed areas of Linyi printing industry.

Walking into the factory, I saw a clean environment and orderly working procedures. Although it is a domestic manufacturer, when we go to the workshop and see the advanced assembly lines and skilled technical level, we will fully feel the modern management. As a manufacturer of printing products, some problems are inevitable, such as the flying of paper scraps, the noise of machines, and the smell of gasoline mixed with pigments, but the factory has tried to minimize them. Walking in the workshop, it seems that the serious problems faced by most wooden manufacturers are not much trouble in our factory, but those management and efficiency attract most visitors.

The factory has its own timetable and will strictly abide by it. Even during lunch break, every worker will clean up his area in order, which is one of the reasons why the factory can keep clean. On the issue of dining, the factory also has its own characteristics. That is, from the top to the ordinary workers, the meals they eat are the same, without any specialization.

Second, the learning process

The following points are the main knowledge I learned during my internship in the factory and some experience I got from my work.

(a) Selection of pigments

The most commonly used pigments in the factory are all advanced in the world, and most of them are imported from abroad, which is also the reason why our quotation is higher than that of domestic manufacturers-it is precisely "a penny for a penny".

Traditional pigments are also one of the commonly used materials. Many products of our company can also use traditional pigments to achieve printing effect. Can be recommended to some customers who want to save costs.

These conventional pigments have a certain amount in the warehouse, and other pigments are also in reserve. Generally speaking, however, conventional pigments are recommended as much as possible (unless the products ordered by customers are large enough, the factory can purchase other expensive pigments), which will be helpful to the processing technology, production cycle and growth cost of the factory.

(2) Processing

The machines used in the factory are all advanced, generally speaking, they are automatically operated, such as large automatic printing presses. So as long as the operation is proper and the personnel arrangement is reasonable, it can generally produce higher efficiency (generally speaking, skilled labor is needed).

Although the factory can produce most of the printed products, in the process of communicating with customers in the future, we should try our best to meet the requirements of customers and stand in the position of the factory as far as possible. For example, you can recommend some samples with the same appearance, but simple practice and clear structure to customers. This can not only reduce the cost for the factory, but also improve the efficiency.

learn knowledge

During the nearly one-week internship, we learned a lot about printing, which is summarized as follows.

Knowledge of color printing.

There are two kinds of printers used in general color printing shops, one is a toner laser printer and the other is an ink printer, both of which are ink materials used by printers. A good machine will have 8 colors and will come out after colliding with each other. However, the pigments printed on books or packaging are professional printing inks, usually four-color inks, which need printing plates to transfer printing, and the effects are different. The difference is not only quality, but also price. Ink for printing machines is much cheaper. But it can't be used before and after.

2. Are the three primary colors of pigment and printing the same?

The answer is different. Theoretically, it should be the same, but once it is actually printed, it will involve the material problem, so not only the name is different (this reason will not be discussed), but also the actual material is different.

The so-called tricolor is just a conceptual term in the theory of artistic color. In the final analysis, that is the three primary colors that are actually applied in various fields. This is the practical part. What pigment is used? It is not difficult for us to understand that the same manuscript, different printing houses and different brands of printers have different final results. Micromanipulation is certainly different, but one thing is certain. Different companies implement different chromatographic standards. Therefore, to sum up, theory is only the guidance of practice, and various methods to realize theory are not the same, which leads to the knowledge of pigment materials.

With the development of science and technology, human beings can constantly update materials. Now we can only say the names of magenta, magenta and yellow, behind which is the secret pigment formula, which directly leads to the brightness (saturation) and transparency of the pigment (directly related to whether the intermediate color is bright and pure in the mixed color mode). This problem is actually the theoretical name of color and the actual material of color, even if we say yellow, lemon yellow and cadmium yellow. Cyan (ultramarine, cyanine and cyan in China pigments); What about magenta, magenta and rose? In fact, there are many pigments that can't be used for printing. For example, the blue in the three primary colors should be closer to the nominal' lake blue' pigment, but it is opaque, so it is not used at all, so we choose ultramarine (or chemical substitute) or indigo with excellent transparency, and all you and I know is blue or cyan.

3. Preliminary understanding of printing machinery.

Modern printing machines are generally composed of mechanisms such as plate loading, ink feeding, stamping and paper feeding. When it works, the characters and images to be printed are first made into printing plates, which are installed on the printing machine. Then, the ink is coated on the place where there are words and images on the printing plate by hand or printing machine, and then directly or indirectly transferred to paper or other substrates, so as to copy the same printed matter as the printing plate.

Printing was first invented in China. Books on printing began to appear in China in the 9th century, and then printing invented by China spread all over the world. The invention and development of printing plays an important role in the spread of human civilization and culture.

Before 1950s, the traditional relief printing technology occupied a dominant position in the printing industry, and the development of printing machines was mainly relief printing machines. However, the lead alloy relief printing process has some disadvantages, such as high labor intensity, long production cycle and environmental pollution. Since 1960s, offset printing with short cycle and high productivity began to rise and develop, and lead alloy relief printing was gradually replaced by offset printing. Flexible letterpress printing, stencil printing, electrostatic printing, inkjet printing, etc. , has also been developed in packaging printing and advertising printing.

4. About health problems.

At present, the common Heidelberg flatbed paper machine uses oxidized conjunctival ink, which is composed of pigment, adhesive, filler, additive, ink blending oil and so on. If it is not inhaled directly, the harm to the human body can not be said to be zero, but it is also quite subtle. Therefore, during the internship, we are all required to wear work clothes and masks like regular employees.

Third, experience

Time passed in the blink of an eye. We have experienced, walked and gained. These short days will be the best memories in my heart. When I sit here and write my thoughts, the trip to the factory has ended, but what happened is often remembered. I want to thank those classmates who spent time with me, who gave me a bitter experience; I want to thank the workers and leaders who accompanied us to the factory, and thank you for your guidance and help. At the same time, I sincerely hope that Lanshan Student Printing Factory will become more and more prosperous.

Chapter III Summary Report on Printing Factory Practice in 2020

I went to xx printing factory in xx city as an intern. It was a small printing factory, but I learned a lot here. After these years of development, the printing industry is still in a period of non-standardization, relative confusion and neglect of management. One of the reasons why I choose to go to the printing factory is the industry. The overall development of the printing industry is rather chaotic, and there are no standardized systems and rules. Secondly, most enterprises are small manufacturers with little management. Under such circumstances, I want to know whether it is possible to make printing stronger and bigger in xx.

Xx printing factory was a busy period a few years ago. Because primary and secondary schools were in the final exam stage at that time, the factory mainly printed test papers. Usually, the factory also prints calendars, documents, stationery and leaflets. In the factory, I am mainly responsible for typing, error correction and other chores. The work itself is not important. These jobs have low technical content, and some of them will get started immediately without learning. Typing is a piece of cake. Input information into the computer as required, paying attention to efficiency and quality. Error correction is a tiring job. Staring at the computer for hours makes me dizzy. It's nothing more than some manual work such as picking up pages and bagging. In freezing weather, these jobs are not easy, and many workers' hands and feet are frostbitten. This makes me very moved. Without knowledge, you can only engage in manual labor, and the rewards you get are scarce, so the value of life cannot be realized.

In the printing factory, when I asked why the factory didn't buy new equipment, introduce new technology, recruit high-quality personnel and introduce new business, the boss told me some hidden rules about the printing industry. There are still many imperfections in xx printing industry. People's living standards are still very low. Small enterprises generally do not attach importance to management, let alone human resource management. Generally, junior and senior high school students are recruited. Because they do things quickly, do not require high-skilled and high-quality talents, and do not pay attention to people-oriented management. If employees are not satisfied with the working conditions and salary, they can resign through consultation, and then the enterprise will recruit other candidates, which will increase the number of enterprises invisibly.

This internship, let me exercise the speed and quality of typing, experience the bitterness of physical labor, and temper my will. While communicating with other people who have not received higher education, I realized the importance of knowledge and the superiority of university education, and made me determined to study hard, seize the good opportunity that everyone is dreaming of now, and strive to learn my professional courses well, and connect my knowledge with the human resources department of the enterprise to pave the way for employment everywhere. Proficient in all aspects of human resource management, and constantly cultivate their own abilities in the future learning process. If you are lucky enough to find a good job, be conscientious and practical, and keep innovating, then if you return to China, you will make a modest contribution to the development of your hometown.
