In many packaging and printing companies are pursuing high efficiency and high profits, especially in the development of high value-added products today, the printed matter of glass card paper can be said to be the pride of high value-added products. Due to its smooth and white material and unusually bright light, it is particularly expensive. At present, most packaging and printing companies use imported glass card paper, but its performance and quality are still difficult to compete with the products of developed countries. The packaging of this kind of glass card paper is enough to make you feel noble about it. The beautiful and beautiful packaging is wrapped in a plastic transparent film. The plastic transparent film is another layer of paper-plastic composite packaging. And it is a small package of 100 sheets per pack (note: this kind of paper produced in China is 250 sheets per pack, and the moisture resistance is also poor).
Glass card paper is widely used. It is most commonly used in high-end pharmaceutical packaging, hang tags in brand-name clothing, invitations for large banquets and large-scale business negotiations, menus used in high-profile luxury hotels, and program lists for large-scale cultural performances. Choosing this kind of material to package its products will give you a sense of exquisite decoration and exquisite materials. The sealing performance of the medicine packaging box made by it is also better, and it has become one of the first choice materials for packaging of high-end products.
Why is glass card paper difficult to print
Glass card paper is difficult to print is a common sigh issued by all industry production practitioners. The reason why glass card paper is difficult to print is that its surface is extremely bright and smooth, which makes the adhesion of the ink more difficult and difficult to grasp. The configuration of the auxiliary materials in the ink also adds a lot of complexity and variability to the printed product. The entire production process also has a great impact. Since the processing of glass card paper is of high added value, customers naturally have very high requirements on its quality, and slight defects and serious consequences. For example, the amount of ink desiccant is difficult to grasp, so this requires our lead machine and ink matching personnel to carry out other processes (such as bronzing) according to the production season, temperature, humidity, batch size and color number at the time. , Raised, crimped). Otherwise, there will be serious consequences of quality problems and the success of the business will cause huge losses to enterprises, resulting in invalid production, so the general SMEs dare not contract processing.
There are three reasons for not daring to contract:
1. No first-class equipment.
2. Weak logistics support.
3. Printing skills are not strong.
Operate with strict production attitude
Because the glass card paper is smooth and bright, the required printing pressure is relatively greater than the pressure of other printed parts. Therefore, full consideration should be taken into account when making the plate. The material selection of the plate nursery must be strong and durable. The double-sided imported glue is used to stick the plate firmly, and the periphery of the plate is separately nailed to prevent the printing plate from separating from the plate holder during high-speed printing The surface of the surface is not allowed to have traces of residual glue. It should be polished with charcoal to make the printing plate free of any remaining foreign objects.
The printing rubber roller should be of high quality, elasticity and viscosity. Used printing rollers must never be used to prevent the surface layer from being scratched and disturbing the printing of new jobs due to scratches. After adjusting the printing rubber roller to the best point, lock the thread of the item. It is best to center the printing plate on the upper plate to make the pressure of the roller and the bearing capacity of the plate table relatively uniform so as not to damage the equipment.
Clean the roller brush. Roller brushes will have dust, paper scraps, and paper wool after a long time of use. In the production process, if there are small paper deposits, the wrapping of the roller will be damaged, and the printing quality will be seriously affected, because it is high-speed printing. At first glance, there are many waste products. Therefore, in production, there is a large sense of responsibility for the fuselage and great mental pressure. You must know that many packaging and printing companies are simulating the market, and they have strict management of material consumption. Once the waste exceeds the standard, the lead will be punished. This is also glass card One of the factors of difficult printing.
It is also critical to remove the dust from the suction nozzle and adjust the amount of suction.
The amount of air intake is small, and the paper cannot be continuously printed and cannot be sucked up, resulting in an increase in the amount of ink. If the suction volume is large, double or multiple sheets will easily appear, which may easily lead to glue wrapping and even damage the printing roller. The gripping tooth row, paper feeding row, and delivery row must be adjusted before printing. If the tension is loose and uncoordinated, deflection will occur during printing and the row will be damaged. Generally, the glass card paper is between 80 grams and 300 grams.
The second color printing is more difficult. When the glass card paper is printed in one color, the effect and quality are relatively satisfactory. Don't be complacent and relax. The second color must consider the accuracy of overprinting. When printing, you should diligently look at the rule line. In order to ensure the accuracy of overprinting, such fine products generally require that the rule line be placed on three sides, which can be checked at a glance. Because the first color is a white card, only pay attention to the quality of the printing, and the second color should also pay attention to the potential quality crisis caused by the movement and scratching of the printed surface patterns during the movement of the equipment. . This also frightened the leader, and the solution was to move all the crimpers away from the printed first-color patterns, so as to solve the problem. In order to prevent the phenomenon of scratches and scratches from re-transferring to other processes after the printing operation is completed, strong protective measures can be implemented, and the ink consumption plate is used to press the oil once. Its ingredients are made up of two-thirds resin resin oil and one-third printing bright spot oil, and then adding an appropriate amount of ink desiccant-white dry oil. This will no longer happen after drying naturally.
Selection of glass card ink
The characteristics of glass card paper have been introduced earlier in this article, so when choosing ink, basically all imported ink. It has the characteristics of strong brightness, bright colors, thin ink layer, and strong adhesion. It is most suitable for glass card paper. Try not to use a few colors to match, but use the desalting agent to adjust the depth and lightness of the ink. The white ink cannot be used because of its complex composition. The white ink is used to configure the ink to have poor fastness. It must be used as a guide.
Although glass card paper is very difficult to print, it can be printed as long as we study it carefully.
Multi-sport artificial grass is extremely practical for boroughs, schools, hotels, universities, and health centers, which have to satisfy as many users as possible in a flexible and hassle-free manner. Many of them need to support multiple sports and recreational needs but have limited space. Synthetic grass allows teams to practice and play games under all weather conditions, and it easily accommodates multiple sports to be played on one field. Using different colors for inlaid game markings, a field`s return on investment can be greatly increased.
