When consumers are squatting in department stores, they are often seen as "eyes" on the shelves, especially those with strong visual impact. The label is the first time to steal the eye of the consumer, and the pleasing product label not only enhances the shelf effect of the product, but also enriches the consumer's shopping experience.
Don't look at the label is not big, its production process is not so easy, no matter which part of the negligence may lead to the final result is not satisfactory, this article will be on the label Some notes on the arrangement of the printing color sequence are discussed.

General principles for determining the color sequence of labels
1. Arrange color order according to the nature of the paper
The suitability of tension, smoothness, whiteness, fiber tightness and ink absorption of different papers is not the same. Under normal circumstances, for paper with good ink absorption, I recommend printing a dark color and then printing a bright color. For paper with poor ink absorption, it should be printed with a bright color and then printed with a dark color. The reason is that bright ink such as yellow ink can cover the hair. Paper defects such as powder drop.
2. Determine the printing color sequence according to the characteristics of the black version of the graphic
The printing color sequence of printed matter mainly composed of characters, lines and black is generally cyan-magenta-yellow-black.
Under normal circumstances, the first color sequence of the four-color machine printing color sequence is often black, but some label prints, most of the black version will be text description, and if the substrate is a poor quality coated paper, When the glue is applied, the black ink of the first color sequence is partially transferred to the surface of the roller of the second color sequence, so that "ghosting" is easily generated. In order to avoid this, black can not be placed in the first color sequence printing, it should be placed in the third color sequence or the final printing is more appropriate.
3. Determine the printing color sequence according to the size of the coverage area of ​​the dots in the manuscript
When the area of ​​the graphic on the printing plate is large, especially when it is full, it is usually printed in the later or last order; otherwise, the large area is printed first. Although the large-area ink color transfer effect is very good, for a small area, the ink is all overprinted on another color (large area) ink film layer, which will affect its effect. Therefore, the author suggests to print the dot area with a small coverage area. The reprinted dot covers a large portion of the graphic area.
4. The printing color sequence of the flat net and the solid part
In order to achieve better label printing quality, avoid the scratches in the printing process, make the flat net soft and even, the ground level is flat, the ink color is bright, I recommend printing the graphic part of the flat screen first, then printing the real part.
5. Determine the content and characteristics of the design draft before determining the print color sequence
When encountering warm-toned prints, I recommend placing magenta and yellow in the rear unit; while cold-toned prints, first print magenta, then print cyan. This is because different printing color sequences will affect the color of the final print, such as printing in magenta-cyan-yellow color order, the product color will be greenish; if the color order is cyan-magenta-yellow, it will be reddish . For the color deviation after overprinting, we can correct it during plate making. In addition, in order to emphasize the main color of the label print screen, we can also make full use of the special effects of the color deviation caused by different printing color sequences to adjust.
6. Determine the printing color sequence according to the nature of the ink
In the printing process, when we print the magenta, yellow or spot color graphic part after printing the black text part, the text is reddish or yellowish. I suggest to use the first printed ground color and then print the black color part of the printing color sequence. . Ink with lower transparency has a greater influence on the color after overprinting, and it is prone to color shift after printing in the subsequent order. Therefore, the ink with lower transparency should be printed first, and the ink with higher transparency should be printed.
7. Determine the printing color sequence according to the viscosity of the ink
The viscosity of the four-color inks is arranged in descending order as follows: black > cyan > magenta > yellow, and black-cyan-magenta-yellow printing color sequence is generally used in the four-color printing machine to increase the durability of the overprint. To prevent "cross-color" and cause blurring of the picture, dark color, dullness and so on. The two-color machine generally uses a cyan-magenta-black-yellow printing color sequence.
8. Arranging the printing color sequence according to the drying speed of the printing ink
Under normal circumstances, I recommend printing the ink with a slow drying speed and then printing the ink with a fast drying speed. The yellow ink is about 1 to 2 times faster than the magenta ink, the magenta ink is about 1 times faster than the cyan ink, and the black ink is the slowest.
Matters needing special attention in label printing color sequence arrangement
When gold or silver ink is required to be printed on the label, the gold ink and the silver ink have little adhesion and are printed in the last color as much as possible. However, these two inks have a strong hiding power, and they will cover the background color completely. Therefore, the plate making factor must be considered before printing. If you do not pay attention to such problems, the text will be inconspicuous or lost.
In the four-color printing, the yellow ink is placed in the final superiority: First, the yellow ink has high transparency, and the final color printing is arranged to facilitate sufficient white light to enter the upper and lower ink layers, thereby obtaining bright and bright colors, which is beneficial to the print material. Better color reproduction; second, the yellow ink has a faster drying speed, and the yellow ink is arranged in the last color printing, which can prevent the glassing caused by the excessive drying speed of the yellow ink, and can fully utilize the large printing area. The oxidized conjunctiva has a high speed and is covered on the surface of other ink layers to make the printed matter have a certain degree of gloss.
In short, in the specific printing process, the best printing color sequence can be flexibly selected according to the overprinting rule, so as to achieve the advantages and avoid weaknesses and control the color deviation, and the most ideal printed matter can be printed.

Medium Duty High Temperature Casters

High-temp wheels feature a standard operating temperature range from -30℃ (continuous service) to 280℃. These are molded from an exclusive engineered resin compound that offers non-marking floor protection, near zero water absorption, high load capacities, and long service life. A special manufacturing process enables these wheels to retain a consistent bearing bore even when exposed to elevated temperatures. Furthermore, Thermo wheels are 100% recyclable, and they are highly resistant to animal fats, vegetable oils, and salt solutions. The life expectancy of Thermo wheels is three times longer than high-temp phenolic wheels, and they offer an equal load capacity. Unlike high-temp phenolic wheels, Thermo wheels have no outer skin that can break and absorb water or other fluids. Medium duty High Temperature Casters can bear 90-120kg load.
