2022-01-03

Cosmetic tube printing technology is a method of copying text and images in batches through plate making, cosmetic tube printing, and post-press processing. The broad interpretation of cosmetic tube printing technology should be: cosmetic tube printing technology is the general term for cosmetic tube printing process and cosmetic tube printing equipment. The cosmetic tube printing process and the cosmetic tube printing equipment are mutually dependent and mutually reinforcing. Simply put, the cosmetic tube printing process cannot be separated from the cosmetic tube printing machine; the cosmetic tube printing machine is also inseparable from the cosmetics Tube printing process. This is how the cosmetic tube printing technology in ancient and modern times has been continuously developed.

The technicians of the cosmetic tube manufacturer must not only be proficient in the cosmetic tube printing process skills, but also should master the knowledge of the cosmetic tube printing process equipment (cosmetic tube printing machine); on the contrary, the technicians of the printing machine manufacturer, Not only is proficient in the design and production skills of cosmetic tube printing process equipment {cosmetic tube printing machine}, but also should master the knowledge of cosmetic tube printing process. The better the combination of the two, the more refined the knowledge of cosmetic tube printing technology, The more beneficial it is to the development of new technologies and new products.


Silk-screen cosmetics tube printing refers to the use of silk-screen as a plate base and a photosensitive plate-making method to make a silk-screen printing plate with pictures and texts. The screen cosmetic tube printing is composed of five elements, screen printing plate, squeegee, ink, cosmetic tube printing table and substrate. Make use of the basic principle that the mesh of the graphic part of the screen printing plate can penetrate the ink, and the mesh of the non-graphic part cannot penetrate the ink for cosmetic tube printing. When the cosmetic tube is printed, pour ink on one end of the screen printing plate, use a scraper to apply a certain pressure to the ink part on the screen printing plate, and at the same time move to the other end of the screen printing plate at a uniform speed, the ink is scraped by the moving plate Squeeze from the mesh of the graphic part to the substrate.



Cosmetic tubes manufacturers predict that in the future, silk-screen cosmetic tube printing will continue to maintain a relatively high development speed, technology will be gradually improved, and the scale of the industry will be further expanded. Authorities predict that in the future, the proportion of world silk-screen cosmetic tube printing in the total output value of cosmetic tube printing will rise to 10%. There is no doubt that the screen printing industry is gestating more room for development and potential markets. It is expected to become the world's largest screen printing market by 2025. Screen cosmetic tube printing will develop in depth and breadth in the future.


The screen cosmetic tube printing consists of five elements, namely the screen printing plate, the squeegee blade, the ink, the cosmetic tube printing table and the substrate. The basic principle of silk-screen cosmetic tube printing is: cosmetic tube manufacturers use the basic principle that the graphic part of the screen printing plate is ink-permeable and the non-graphic part is impermeable to ink. When the cosmetic tube is printed, pour ink on one end of the screen printing plate, and use a squeegee to apply a certain pressure on the ink position on the screen printing plate while moving toward the other end of the screen printing plate. The ink is squeezed onto the substrate by the squeegee from the mesh of the graphic part while moving. Due to the viscosity of the ink, the imprint is fixed within a certain range. During the cosmetic tube printing process, the squeegee is always in line contact with the screen printing plate and the substrate, and the contact line moves with the movement of the squeegee, due to the screen printing plate Keep a certain gap between it and the substrate, so that the screen printing plate of the cosmetic tube printing produces a reaction force against the squeegee through its own tension. This reaction force is called the resilience force. Due to the effect of resilience, the screen printing plate and the substrate are only in mobile line contact, while other parts of the screen printing plate and the substrate are in a disengaged state. The ink and the screen are broken, which ensures the dimensional accuracy of the cosmetic tube printing and avoids smearing the substrate. When the squeegee is scraped across the entire layout, it is lifted, and the screen printing plate is lifted at the same time, and the ink is gently scraped back to the original position. So far is a cosmetic tube printing stroke.


Advantages of screen cosmetic tube printing from cosmetic tube manufacturer:


(1) Not limited by the size and shape of the substrate


Generally, cosmetic tube printing can only be performed on a flat surface, while screen printing can not only print cosmetic tube on a flat surface, but also print on a special shape of a molded object, such as a cosmetic tube on a spherical curved surface. Anything with a shape can be printed. It can be done with silk-screen cosmetic tube printing.


(2) The layout is soft and the printing pressure is small


The screen is soft and flexible.


(3) Strong ink coverage


It can be printed on pure white cosmetic tube on all black paper, with strong three-dimensional effect.


(4) Suitable for various types of inks


(5) Strong anti-rotation performance


The cosmetic tube manufacturer can keep the gloss of the cosmetic tube printed matter unchanged. (Neither temperature nor sunlight has any effect). This eliminates the need for additional laminating and other processes when printing some stickers on the cosmetic tube.


(6) Flexible printing methods for cosmetic tubes


(7) Convenient plate making, low price, easy to master technology


(8) Strong adhesion


(9) It can be silk-screened by hand or machine-printed


(10) Suitable for long-term display, and expressive outdoor advertising




Strong printing adaptability for cosmetic tube

The three major cosmetic tube printing methods of flat printing, embossing and gravure printing generally can only perform cosmetic tube printing on flat substrates. The silk-screen cosmetic tube printing can not only print cosmetic tubes on flat surfaces, but also print cosmetic tubes on curved, spherical, and concave-convex substrates. On the other hand, screen cosmetic tube printing can not only print on hard objects, but also on soft objects, without being restricted by the texture of the substrate. In addition, in addition to direct cosmetic tube printing, cosmetic tube manufacturers can also use the indirect cosmetic tube printing method for cosmetic tube printing according to their needs, that is, first use the silk screen cosmetic tube to print on the cosmetic tube. On the gelatin or silicone plate, then transfer to the substrate. Therefore, it can be said that the printing adaptability of the screen cosmetic tube is very strong, and the application range is wide.



Strong three-dimensional


The thickness of the ink layer for offset printing and embossing is generally 5 microns, and the thickness of the ink layer for gravure printing is about 12 microns. The thickness of the ink layer for flexographic (aniline) cosmetic tube printing is 10 microns, and the thickness of the ink layer for silk-screen cosmetic tube printing It far exceeds the thickness of the above-mentioned ink layer, generally up to about 30 microns. The printing ink layer of the silk-screen cosmetic tube is thick, and the printing quality of the cosmetic tube is rich and the three-dimensional impression is strong. This is incomparable with other cosmetic tube printing methods. Silk-screen cosmetic tube printing can not only print monochrome cosmetic tube, but also can print color cosmetic tube and screen color cosmetic tube.


 


Strong light resistance


Bright color. Because the screen cosmetic tube printing has the characteristics of missing printing, it can use various inks and coatings, not only can use slurry, adhesive and various pigments, but also can use coarser particles. In addition, the screen cosmetic tube printing ink formulation method is simple, for example, the light-resistant pigment can be directly put into the ink for formulation, which is another major feature of the screen cosmetic tube printing. Screen cosmetic tube printing products have a great advantage of strong light resistance. Practice has shown that, according to the maximum density value range measured after using black ink on coated paper for one time stamping, offset printing is 1.4, embossing is 1.6, gravure printing is 1.8, and the maximum density of silk-screen cosmetic tube printing The value range can reach 2.0. 


 


Large printing area for cosmetic tube


Generally, the area size of the cosmetic tube printed by the cosmetic tube printing methods such as offset printing and embossing is the maximum size of the full sheet. If the size of the full sheet is exceeded, it is restricted by mechanical equipment. The screen cosmetic tube printing can be used for large-area cosmetic tube printing. Today's screen cosmetic tube printing products can reach a maximum range of 3 meters × 4 meters, or even larger.


The above four points are the differences between screen cosmetic tube printing and other cosmetic tube printing, as well as the characteristics and advantages of screen cosmetic tube printing. Knowing the characteristics of screen cosmetic tube printing, cosmetic tube manufacturers can use their strengths and avoid shortcomings when choosing cosmetic tube printing methods, highlighting the advantages of screen cosmetic tube printing, so as to achieve more ideal cosmetic tube printing Effect.


 


Silk-screen cosmetic tube printing, like other cosmetic tube printing, needs to accurately reproduce the graphics and color of the original manuscript. In principle, the manuscripts used in screen cosmetic tube printing are not very different from ttube used in other cosmetic tube printing methods. However, in the specific practice of plate making and cosmetic tube printing, the requirements are different. This is mainly due to It is determined by the printing characteristics of the screen cosmetic tube. Especially because the printing ink layer of the screen cosmetic tube is thick and the color is bright, the special effect of the screen cosmetic tube printing should be fully considered when selecting the original and plate making.


In addition, the graphic lines and dot accuracy requirements of the original manuscript used in the silk-screen cosmetic tube printing are also different from ttube used in the ordinary cosmetic tube printing method. If the lines and dots of the original manuscript are very fine, it is very difficult to use silk-screen cosmetic tube printing to make a plate. Therefore, the silk-screen cosmetic tube printing technology is not suitable for reproducing the original manuscripts with fine lines and dots. When choosing a cosmetic tube printing method, we must fully consider the characteristics of various cosmetic tube printing. Even in the printing and plate making of the silk-screen cosmetics tube, the same attention should be paid to the selection of the appropriate screen line, in order to achieve the purpose of fully reproducing the original manuscript.


The silk-screen cosmetic tube printing is more suitable for single color manuscripts with crisp text and lines, and it is also suitable for color manuscripts with large contrast and clear gradation. The special effect of the silk-screen cosmetic tube printing makes the reproduction rich in expressiveness. Through the rich and thick ink layer and the contrast of light and dark tones, the texture and three-dimensional effect of the original content are fully expressed.


There are two types of manuscripts for photoengraving of silk-screen cosmetics tube printing: reflective manuscripts and transmissive manuscripts, and reflective manuscripts are usually used. Most color photography uses transmissive originals. Silk-screen cosmetic tube printing mainly uses positive pictures to make screens. Different plate making methods have different requirements for manuscripts.


 


The characteristics of screen cosmetic tube printing can be summarized as follows:


① Screen cosmetic tube printing can use many types of inks. Namely: oily, water-based, synthetic resin emulsion, powder and other types of inks.


②The layout is soft. The silk-screen cosmetic tube printing layout is soft and has a certain degree of flexibility. It is not only suitable for printing on soft articles such as paper and cloth, but also suitable for printing on hard articles.


③The printing force of the screen cosmetic tube is small. Since the pressure used when printing cosmetic tubes is small, it is also suitable for printing cosmetic tubes on fragile objects.


④The ink layer is thick and the covering power is strong.


⑤ It is not restricted by the surface shape and area of the substrate. From the foregoing, it can be seen that the silk-screen cosmetic tube printing can not only print on flat cosmetic tubes, but also on curved or spherical surfaces; it is not only suitable for printing cosmetic tubes on small objects, but also suitable for printing on larger cosmetic tubes. Cosmetic tube printing on the object. This cosmetic tube printing method has great flexibility and wide applicability.


 


There are usually two types of screen cosmetic tube printing, namely manual cosmetic tube printing and mechanical cosmetic tube printing. Manual cosmetic tube printing refers to the manual operation from paper feeding to paper delivery, the up and down movement of the printing plate, and the scraping and printing.


Mechanical cosmetic tube printing means that the cosmetic tube printing process is completed by mechanical actions. Among them, it is divided into semi-automatic and fully automatic cosmetic tube printing. Semi-automatic means that the substrate is put in and taken out by manual operation, and the cosmetic tube printing is completed by machinery; fully automatic means that the entire cosmetic tube printing process is completed by machinery.


There is also a fast and simple method of printing on cosmetic tubes on curved screen printing screens, which involves removing the screen layout and directly attaching it to the surface of the substrate to print on cosmetic tubes. Using the live screen printing method, a large number of processed prints can be printed. At the same time, this method can be used to print signs on cars, and can also be printed on special-shaped planes.


The production of the live screen: first dry and repair the photosensitive text and graphic plate, then take it off and cut it according to the size. And use wood or aluminum sheets as the skeleton at both ends of the screen to be tightly fixed with adhesive tape, or directly glued with glue, so that the required active screen can be made. The operating method of the live screen: choose different printing materials according to the substrate to be mixed: first select the plate and the plate, and mix the ink, and then, one person holds the live screen with both hands, and the printed part is tightly attached to the substrate. On the surface, another person uses a squeegee to evenly dip the ink on the upper mouth surface of the squeegee, and then places the squeegee on the ink adjustment plate evenly on the layout surface for uniform scraping.


If the printed graphic area is too large, the cosmetic tube manufacturer can pour the ink on the plate according to the situation, but do not let the ink flow out of the substrate. Pay attention to the blended ink not to be too thin or too dry, it is better to dry and wet moderately. Small-area printing and painting can be operated by one person. The method is to stick one end of the movable plate on the required position of the substrate machine with packaging tape, and then use the other hand to tighten the printing plate against the substrate. Perform cosmetic tube printing. Note for starting the plate: Be sure to start the plate lightly according to the direction of the tape that is pasted. The same is true if two people operate the plate advertising. Using this method of cosmetic tube printing, it is easy to operate, flexible and capable of printing substrates. Small, the quantity can be more or less. For cosmetic tube manufacturers, it has the advantages of low cost and energy saving.
