Recently, many customers have come to us to print instructions, but they do not understand the basic process and technology of luxury packaging boxes wholesale printing factory. Today, we will share with you the basic process and process of luxury packaging boxes wholesale printing plant
luxury packaging boxes wholesale process basic process: design to send pictures → proofing → plate composition → plate printing → machine printing → post-press processing → delivery
First, out of film: Out of film is to make a good layout, through the device output to the PC film that can be printed, the professional term is called film.
Film: The film used for printing and plate making is called film film, and the PS plate can be printed on the machine with film film, which is equivalent to the negative of a photograph. It is an essential process in precision printing. Color printed film usually consists of 4 sheets (one each for C, M, Y, and K).
Two, proofing
In the process of printing production, the process of printing a properly corrected negative produced by photographic or electronic color separators into a proof or other method to display the effect of plate making before printing. The purpose is to confirm that the setup, handling and operation of the printing production process are correct, and to provide the customer with a sample of the final print, which is not required to be exactly the same in visual effect and quality as the final print. Proofing can be roughly divided into three methods, that is, proof machine proofing, (toner) simple proofing, digital proofing.
Proof machine proofing: the most traditional and most reliable proofing method. It uses equipment, plates, paper and ink similar to the formal printing press, but the proof machine is generally monochrome or two-color machine (only one or two colors can be run at a time), the degree of automation is not high, the need for high operating skills and experience, and the printing plate must be made in advance, so the proof machine proofing efficiency is low, the need for constant temperature and humidity environment control, the cost is high. This proofing method is the most widely used in China.
Simple proofing: a photochemical reaction to obtain images and color proofing technology, mainly laminated film proofing and toner proofing two. The common feature of these two methods is that the color separation dot film (such as yellow plate) and attached to the film or paper substrate on the photosensitive polymer coating (using the vacuum method), through the color separation screen film side with ultraviolet light source exposure, so that the exposure part becomes insoluble or lose the adhesion, and then through solution development or color powder development, you can get color images. The difference is that the former uses four photosensitive polymer coatings with yellow, magenta, blue and black pigments respectively, and superposes the exposed and solution developed films together to obtain a transmission type color sample. The latter uses a piece of paper the same as the actual print, the colorless adhesive polymer coating (similar to self-adhesive) is attached to the above (using a special laminator), after exposure, toner development processing, repeated four times, you can get a reflective color proof. However, because the imaging process is very different from the actual printing process, it is difficult to achieve the proof and the print is completely consistent.
Digital proofing: Unlike the above two methods, neither intermediate color separation screen film nor printing plate is required. The digital color image (also known as digital page or digital film) generated in the digital prepress system (computer) is directly converted into a color proof, that is, the proof is directly from the computer. Digital proofing is divided into soft proofing and hard proofing. Soft proofing is to display the digital page directly on the color display (such as computer display), it can do real-time display with the computer processing, with the advantages of fast and low cost, but because it is the principle of additive color rendering, and the material and observation conditions are far from the actual print, there is now the use of liquid crystal display soft proofing, has been improved. Hard proofing is the same as computer color inkjet, which directly converts digital pages into color hard copies (using inkjet printing, dye sublimation, hot wax transfer, color electrostatic photography and other imaging technologies). Due to the progress of computer image processing and simulation and control technology, although the paper and color agent are not exactly the same as the actual printing, the digital hard proofing can be very close to the actual print effect, and high-quality products (such as dye sublimation) can reach more than 95% of the complete consistency. Because of its fast, efficient and direct digital conversion characteristics and the development of digital printing technology and networking, it has become one of the main proofing methods.
Third, make up
Composition is also known as "loading", "group". The second step in manual typesetting. In the work will not always do 16K, 8K and other regular open number of prints, especially packaging boxes, small cards (certificates) and so on are often not open, at this time, you need to pay attention to the finished product as far as possible in the paper opening range, in order to save costs.
Four, print
Printing is exposure, printing is the printing of pictures and texts on film, sulphate paper and other carriers with higher transparency, through exposure, the printing of pictures and texts to the screen plate coated with sensitive material, PS plate, resin plate and other materials. On the screen plate, PS plate, resin plate surface coated with a layer of sensitive film after drying, the image of the film is covered on the top, through strong light irradiation of the film, the image on the film is exposed to the sensitive film on the plate, this exposure and photocopying process is commonly known as printing plate. (Paper printing is usually done in Photoshop.)
Five, on the machine printing
Fix the printed PS plate to the rubber roller of the printing machine, adjust the ink, and start printing.
Six, post-press processing
Post-printing coating, indentation, folding, pasting, UV, binding, embossing, gold stamping, soup silver and other processes.
Vii. Packaging and delivery
After the processing is finished, we have professional staff to package it and then our company's delivery man will deliver it directly to the customer.

This paper will discuss from two aspects of price and quality.
First, let's look at the price of the machine tool. Price is a factor that will be considered when buying any product, and Rotary Table Intelligent Assembly Machine is no exception. The price difference of inclined bed machine tools on the market is large, mainly affected by the following factors:
1. Brand: Well-known brands of machine tools are usually higher in price, because behind the brand represents a certain quality assurance and technical strength. However, brand is not the main factor in determining price, consumers also need to choose the right brand according to their needs and budget.
2. Configuration: The configuration of the inclined bed machine tool is different, and the price is also very different. For example, the quality and performance of key components such as spindle, guide rail and motor are different, and the price will be different. Therefore, when purchasing, consumers need to choose the right configuration according to their own processing needs.
3. After-sales service: Quality after-sales service is also an important factor affecting the price of inclined bed machine tools. Some manufacturers provide long-term free maintenance and technical support, while some manufacturers need consumers to bear certain maintenance costs. Therefore, when purchasing, consumers need to take into account the cost of after-sales service.
Rotary Table Intelligent Assembly Machine The relationship between price and quality
Next, we look at the quality of the inclined bed machine tool. Quality is an important standard to measure the quality of a product. For Rotary Table Intelligent Assembly Machine, quality is mainly reflected in the following aspects:
1. Accuracy: The accuracy of the inclined bed machine directly affects the quality and efficiency of the machined parts. The high-precision inclined bed machine can ensure the dimensional accuracy and shape accuracy of the machined parts, thereby improving production efficiency and product quality.
2. Stability: The stability of the inclined bed machine determines the reliability and service life of the equipment. Stable equipment can ensure long-term continuous work, reduce the probability of failure, and reduce maintenance costs.
3. Operability: The operability of the inclined bed machine tool is related to the efficiency and safety of the operator. Easy-to-operate equipment can reduce operator learning costs, improve work efficiency, and reduce safety risks during operation.
To sum up, the purchase of a cost-effective Rotary Table Intelligent Assembly Machine needs to be comprehensively considered from two aspects: price and quality. In terms of price, consumers need to choose the right brand, configuration and after-sales service according to their own needs and budgets; In terms of quality, consumers need to pay attention to the accuracy, stability and operability of the equipment. Only in this way, can you buy a tilted bed machine that meets your own needs and has a high cost performance.

The design scheme of the tourism traffic hubs signage project system is a relatively authentic organic chemistry process. Interior designers must have a sufficient grasp of the physics of the material and be familiar with the compressive strength, ductility, folding degree, rust prevention, corrosion prevention and other characteristics of the material. When making, the first thing you need to master is the production process, the selection of materials and application levels of tourist attraction signs, and you need to pay attention to several aspects.
Sign safety factor
The identification system is a public cultural service equipment associated with everyone's fortunes and stability, and the provisions of its material safety factor are various aspects. For example, the off-ground installation of signs should take into account the net weight of the material and the load capacity of the building, some special places should take into account the elements of the late use, such as children's amusement parks, kindergartens should minimize the application of easy to break, sharp materials, to choose soft wood, plastic is more appropriate.
Sign matching flexibility
Different materials have different characteristics, such as different levels of performance and use period, when choosing two or a variety of materials to be used together, it is necessary to carefully consider the flexibility problem in the middle of the composition of materials. Some signs will fall off each other due to the different levels of thermal expansion and contraction of the component materials, and some signs will cause overall damage due to the use period of some materials, which shows that the selection of scientific and effective material matching methods are immediately related to the robustness and safety of guided signs.
traffic hubs signage project Natural environment application scope
The provisions of the composition materials of the sign plate are not the same with the difference of indoor space in the natural environment. For example, the open holiday tourism natural environment sign should take into account its durability, passenger flow and other factors and choose durable materials to prevent the application of irrational behavior of visitors and cause damage; In the relative working environment, the sign can choose a good material, and can also add a light source, sound media, etc. In addition, the topography can not be ignored, the location is not the same, the climate is very different, and the identification should be taken into account in the selection of materials and processing technology.

Due to the high speed of the train, high-speed rail requires elastic rail spikes with sufficient buckling force, a large elastic area and strong track retention, but must also have the following characteristics. Reduce fastener maintenance. Once the high-speed line is opened, due to the high speed and high density of trains, track maintenance can only be carried out during short blockades. This requires that each part of the fastener has sufficient strength and durability.
The fastener has good noise and vibration reduction performance. The dynamic effect of the track increases dramatically as the train speed increases. Therefore, the subway fastener must have good noise reduction and vibration reduction performance, that is, the fastener must use a better elastic plate. In order to ensure the absolute safety of high-speed railways, fasteners must have good insulation properties, and there must be sufficient impedance between the two rails to ensure the normal operation of the track circuit.
After the high-speed development of railways, the use of large maintenance machines without operating carrier plates and Type III screwless spring rod fasteners means a reduced number of parts and easy loading and unloading in the long run, which can significantly reduce maintenance and repair costs. In order to meet the needs of high-speed ast tracks, spring rod subway fasteners must use plastic housing instead of sulfur anchors.
In the construction of the Type II fastener connector, the screws are bent and the plastic housing cannot be pierced. It is easy to loosen, and other protective measures must be taken to prevent screw corrosion. However, Type III elastic fasteners do not have these problems. Type 60210217 rubber mounting plate is recommended for the lower guide rail mounting plate. The static stiffness ranges from 55 kNΠmm to 80kN πmm. More satisfactory results can be obtained.

For efficient metal cutting, machining data, tools and cutting conditions are the three major elements. These determine the machining time, tool life and machining quality. An economical and effective machining method must be a reasonable choice of cutting conditions.
Three factors of cutting conditions: cutting speed, feed rate and depth of cutting directly cause tool damage. As the cutting speed increases, the temperature of the tip increases, and mechanical, chemical, and thermal wear occurs. A 20% increase in cutting speed can reduce tool life by half.
The relationship between feed conditions and tool wear occurs on a small scale. However, the feed rate is large, the cutting temperature is increased, and the back wear is large. It has less effect on the tool than the cutting speed. The effect of cutting depth on the tool is not cutting speed and feed, but in the micro cutting depth, the rigid layer generated by cutting parameters will also affect the life of the tool.
Users should choose cutting speed according to Rotary Table Intelligent Assembly Machine machining data, hardness, cutting state, data variety, feed rate, cutting depth, etc. Select the most suitable processing conditions according to these elements. Regular and steady wear is the ideal condition. But in practice, the choice of tool life is related to tool wear, machining size change, surface quality, cutting noise, processing heat and other factors. Stop the discussion on the basis of confirming the processing conditions and requirements. For refractory materials such as stainless steel and heat-resistant alloys, coolant or rigid blades can be used.

After installation, outdoor signs business can bring real and effective guidance and instructions to people, so that people have a good visual feeling, which mainly depends on the communication between designers and builders. As a whole, the logo design should be novel, eye-catching and full of personality, and emphasize regional characteristics. Among them, the traffic signs need to be carried out in strict accordance with the national standards, and the other signs must consider the characteristics of the city in all aspects of the design and modeling, fully showing the spiritual outlook of the people of a region, regional culture and so on.
Today, the sign is here to share with you that we are very much looking at these aspects of the sign design, and I hope that we all have a lot of understanding of the sign design concept.
The first is safety: combined with whether it is reasonable, safe and stable, designers need to consider a number of factors, it will not be affected by the growth of surrounding plants, will not fall for a long time, will be blown down by the wind will not bring security risks to people and other factors.
The second is the function: the instructions are in place, the function is still relatively clear, outdoor signs business has some functions such as instructions, warnings and so on, although the function is ranked second, when the sign design can meet the function, the function of instructions and warnings is difficult to reflect.
The third is the shape: the lines are bright, beautiful and generous, and the requirements of cooperative customers for this piece are particularly obvious. In the process of more than ten years of work, we continue to cooperate with customers to communicate, modeling is our design of the two principles (safety, function) and planning of the three principles (reasonable, smooth, comprehensive) to make the basis. Designers will not blindly pursue a very eye-catching, attractive special shape, and ignore safety; It will not be stubborn in the gorgeous, beautiful layout effect, and can not meet the basic functional needs of the logo.

hidden gps tracking device has been applied more and more widely, and more and more people use it at the same time, there are many "rumors" or cognitive misunderstandings about hidden gps tracking device on the market. Today Xiaobian will come and you take stock of those who are believed to be true rumors.
Myth # 1: GPS can be located anytime, anywhere.
The hidden gps tracking device does not have a signal everywhere, and there are a lot of interference factors that can affect the device's satellite search when the signal is insufficient. Visible, such as a tree on the side of the road, invisible, such as radio waves, which will affect the normal signal search of hidden gps tracking device.
Now many companies are coming up with ways to try to solve this problem. For example, GPS and LBS positioning exist at the same time. If there is no GPS signal, LBS positioning is enabled. However, the world is so big that there will always be places where neither signal is available.
Myth 2: The hidden gps tracking device signal graph is the perfect way to show how good the device signal is
When we buy hidden gps tracking device offline, many merchants will explain the signal quality of this device to you through the device information displayed on the computer platform or APP. Indeed, in this way it can be used as a basis for judgment, but it is not absolute. Moreover, there are many businesses that will make this signal data look more convincing through some modification software.
So don't buy too much believe in this statement, to have their own judgment, from other aspects to choose.
Myth # 3: There are many hidden gps tracking devices that enable indoor positioning
The hidden gps tracking device's signal search can be affected by a number of things, from small trees to large radio waves, and one is the skyscraper in our daily life. Inside, also inside the building. Because these buildings are shielded by concrete and steel, there is no way for the signal to penetrate. The signal can be received indoors unless you stand by a window and let the device pick up the signal from an open area outside the window. Indoors, the signals we see that can be received come from LBS base stations or WiFi positioning. Each of the three positioning methods has its own advantages and disadvantages, and there is no way to change their original characteristics according to the current technology.
Therefore, indoor, if there is WIFI, WIFI positioning is the best choice. If not, try to leave the building and park in an open area.
Myth # 4: It is now possible to hide gps tracking devices without inserting cards
This is the biggest rumor, and we have specialized in popular science before. The so-called free card locator is not not inserted card, but the manufacturer built the card into the device according to demand. Without the card, the device has no signal, there is no way to signal transmission. And if the card locator fails, the later repair is also very challenging, for the owner, it will greatly affect the daily experience.
The card is inserted to obtain signals, transmit data and save data. Free card, seemingly convenient, later when there is a problem, it will be a hundred times more trouble, try not to covet the convenience of the moment.
In short, when buying a hidden gps tracking device, don't just consider one factor, do your homework in advance. It is best to choose big brands for cooperation, professional service personnel will tell you the right style before buying, and later protection is also comprehensive.
