Full analysis of cosmetic tube printing

Bulk cosmetic tube offered by custometic tube manufacturer, is a convenient and economical form of packaging welcomed by the public. It is one of the packaging series favored by packaging industry at home and abroad. Mainly used for liquid, paste and other articles packaging, widely used in daily chemical, medicine, food and other industries. The printing method of the Cosmetic Tube is closely related to the process of making the tube. It is mainly divided into two categories: one is made of cosmetic tube and then printed, which is mainly used for extruded plastic cosmetic tube. Printing methods are mainly relief offset printing and screen printing; The other is to print a plastic film (or composite sheet) and make a composite cosmetic tube. Mainly used for plastic composite cosmetic tube and aluminum composite cosmetic tube. Flexographic printing and gravure printing are adopted.

Thus it can be seen that there are four modes of printing active in the printing of cosmetic tube, and what are their technical characteristics in the printing of cosmetic tube 7 What are they suitable for the printing of cosmetic tube 7 With these problems, After the cosmetic tube is formed, the printing method can be either relief offset printing or screen printing for cosmetic spplier.

Now. Relief offset printing occupies the main position, and screen printing with its distinctive characteristics. It is an indispensable supplementary printing method for relief offset printing.

1. Relief offset printing on Cosmetic Tube printing. Relief offset printing technology is different from the usual sense of paper offset printing. Someone figuratively called it "DryOffset printing" (Dryoffset). In fact. It combines the features of relief and offset printing. Foreign counterparts call it a LetterSet." Industry insiders appropriately call it dry offset printing. In order to avoid confusion with standard offset printing process. Cosmetic Tube offset printing process without water roller. It uses a high viscosity slurry ink. The inker roller transfers ink from the inker to a set of cots. Through a series of rollers, the ink is very evenly distributed on the roller roller roller transfer ink to the letter-text part of the letter-text part on the printing plate rolling sheet raised about 0.50 mm higher than the blank part. Then the printing plate on the ink transfer to the rubber rolling blanket. It is then transferred to the surface of the compound Cosmetic tube. A relief offset printing plate consists of a substrate and a photosensitive polymer layer, the substrate is generally a metal or photosensitive polymer resin. Plate based on metal plate printing resistance is slightly higher, even if it is a resin based plate. The resistance can also be 150,000 to 200,000 Cosmetic Tubes. There are several reasons why relief offset printing is considered the main printing method for tube printing.

   
   

(1) good printing effect relief offset printing process has the characteristics of relief printing and offset printing, the two kinds of printing technology are relatively mature. In four - color printing, you can achieve four - color dot overprint, relative to screen printing. The letterpress offset printing is more fine, so you can copy some gradients. Rich layers of art design draft. In the Cosmetic Tube offset printing process. In monochrome printing, the maximum number of mesh lines can reach 175 lines/inch; When multi-color overprint, the number of net lines can reach 100 ~ 110 lines/inch. But. The color reproduction effect of this printing method is certainly not comparable to paper offset printing.

(2) Multicolor printing uses relief offset printing to print Cosmetic Tube except CMYK four-color printing. For the customer's packaging decoration design often also use some spot color. At present. Eight-color printing machines have appeared internationally in the area of Cosmetic Tube offset printing. Some of the customer's specific requirements have been met.

(3) High speed and high production capacity in the automatic Cosmetic Tube production line. The tube was molded and printed at the same time. Printing presses, extruders, injectors and covering units constitute the Cosmetic Tube automatic production line. The total production rate of the Custometic Tube Manufacturer's production line can reach 100 units per minute. Some relief offset presses specifically designed for the printing of the Cosmetic Tube can print at speeds up to 200 PCS/min (printing speed is related to the diameter of the Cosmetic Tube). Also, Cosmetic Tube presses are generally equipped with glazing units. UV ink and UV varnish. Realized the printing, glazing line high-speed production. It's on the production line. Through the conveyor belt. Semi-finished products can be finished from extrusion to final products without manual handling. Therefore, it can meet the requirements of large orders and ensure the delivery of products on time.

(4) the printing cost is low compared with screen printing. The printing cost of relief offset printing is relatively low for custom cosmetic tube supplier. The reasons are: one. Relief offsctdruckereien UV ink than screen printing UV ink cheaper; The other. Relief offset printing is an indirect printing method. The ink has to be transferred twice from the plate to the surface of the Cosmetic tube so the ink film transferred to the surface of the Cosmetic tube is obviously thinner. The amount of ink is much less than screen printing; Thirdly. Relief offset printing speed is fast. The high production capacity reduces the printing cost per Cosmetic tube.

(5) Stable quality. Convenient detection Automatic Cosmetic Tube production line is equipped with automatic camera and automatic tubing device. The automatic camera device stores the image information of standard products. Then scan each print of the Cosmetic Tube. Comparing with the stored standard information, it automatically determines whether the product is qualified or not. And remove the non-conforming products. Product quality inspection is very convenient. The whole printing process ensures that the printing quality of Cosmetic Tube is within a stable range.

2. Screen printing at Cosmetic Tube Printing Market. Screen printing has its own characteristics.

One of the notable features of screen printing is that the ink layer is thick, which is covered in tube printing and this feature further demonstrates the value of screen printing.

In the first place. Printing ink layer thick three-dimensional sense. The color saturation is very bright. The whole picture to achieve a vivid state of color replication on the shelf to attract the attention of consumers. Secondly. At present, a variety of color Cosmetic Tube with special effects have appeared in the domestic and foreign markets of Cosmetic Tube packaging. Examples include pearlescent, metallic sheen and leather Cosmetic Tube. The manufacturer prints the surfaces of these trendy Cosmetic tubes. The thick ink layer of screen printing effectively covers the color sheen of the Cosmetic Tube itself. In particular, the dark color of the Cosmetic Tube, the whole Cosmetic Tube, after printing, shows the beauty of the flowered color. The thin ink layer of the relief offset printing does not conceal the color of the tube itself. Therefore, it is not suitable for printing of this type of colored Cosmetic Tube.
