High speed shutter door is a rapid operating, anti-crash shutter door for indoor application . The most advantage of this door is that the opening/closing speed can reach to 0.6-1.8m/s, really fast action a lot than tranditional rollling shutter door. short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
High speed door can be easily installed, economical,quiet and efficient with electromechanical drive.
This door quickly though in/out open gate, ideal for warehouses,factories, hangars use, widths can be from 2m to 20 meters.
The material of this door are variety: PVC curtain to keep the insdie clean, heavy duty aluminum door with wind-resisitant function can wrok in heavy windy weather, and also the freezer door can be used in cold warehouse or somewhere like that.
Including models are:PVC High Speed Door, Aluminum Spiral High Speed Door, Self-Recovery repair door, Cold Storage Room Fast Door.

Spot color ink market demand
In recent years, with the increase in the level of printed materials and the increase in the number of external single-products, packaging machinery, such as trademarks, certificates, packaging, and high-end albums, have increased the accuracy of a particular color. If these colors are overprinted with four inks of cyan, magenta, yellow, and black, the amount of ink is difficult to control, which often results in a large change in the printed color or no target color at all. In this case, in order to ensure the stable quality of the printed matter and the precise color reproduction requirements of Huaguang Precision, customers often require the selection of spot color printing. The so-called spot color printing is to use the spot color of the corresponding spot color ink for customer-specified colors. Because the spot color ink is selected according to the color characteristics and brightness (whiteness) of the target color specified by the customer, it is printed in monochrome. Therefore, there is no interference ticket printing due to the overprinting and deformation of the printing dot, and the edges of the picture are neat. The color appearance is stable. Printing market
Professional inks are mainly used in the fields of packaging, trademarks and high-grade printing products, such as cigarette packaging boxes, medicine packaging boxes, cosmetics packaging boxes, banknotes, stamps, anti-counterfeiting labels, high-grade pictures, and handbags.
At present, there are several sources of spot color inks: one is to customize or purchase its standard spot colors to ink manufacturers; second, to customize or purchase its standard spot colors to professional ink distribution companies; third, the printing companies use base inks to modulate at a certain ratio Spot color inks. Purchasing spot-color inks is not only more expensive (more obvious in batches hours), but also increases the printing costs for variable data printing, and it is difficult to guarantee the purchase cycle, which affects the delivery time of printed products. Therefore, printing companies often need to prepare their own spot color inks.
Spot color ink method
There are several commonly used color matching methods: empirical color matching, reference color matching, and computer color matching.
(1) Experience color matching method. Experience color matching is based on the experience accumulated by color matching personnel for many years. This color matching method has high requirements on the experience of the color matching personnel, subjective dependence, and can not quantitatively describe the certification, and often requires repeated modulation over many times, resulting in the deployment of ink volume greater than the demand, resulting in waste. Some companies will also create databases for previously prepared spot color inks, which can be directly searched the next time they are used, speed up digital printing in China, and reduce waste. However, this method cannot cope with customer changes and is difficult to find when the database is large. Founder
(2) Reference color matching method. Because chromatography is formed by four-color overprinting, the color rendering effect is not completely consistent with spot color printing. Therefore, the reference color matching ink can solve the problem of spot color preparation, but the accuracy is poor.
(3) Computer color matching method. Computer color matching is to use color matching software coupled with related measurement equipment. According to the color value of the target color obtained by the measurement, the search and calculation award is made in the software database and the formula is given. This color matching method is widely used in ink color matching because of its high efficiency, low cost, simplicity, and quickness.
At present, the database of computer ink color matching system is established on the basis of wavelength measurement, calculation of tristimulus values ​​or matching of other derivative parameters, and it is often necessary to specify the base ink. These proven basic inks are generally more expensive, and it is generally more difficult for printing companies to bear their costs and it is difficult to popularize them.
Characteristics of CFS spot color ink system
After many years of painstaking research on EFI, experts from the Institute of Printing Science and Technology of China found that there exists a complex color spectrum vector function in the human visual system, showing the vector characteristics of color. The relationship between color and frequency is linear, and the ink color matching system based on this theory can reduce the interference factors and improve the accuracy of color matching. CFS ink color matching system is based on its own mathematic model method color sequence, measuring the color appearance of target samples and basic colors by spectrometer, and calculating the spot color formula. CFS spot color ink system features are as follows. Washing supplies packaging
1 Despite the different brands of inks used in the various printing plants, the CFS spot color ink system can quickly deploy the desired spot color no matter which type of ink is used; Heidelberg
2 The colorimetric measurement function can both qualitative and quantitatively provide accurate data for spot color calculations;
3 The mathematical model built can calculate the spot color formula through the target document and the basic color ink database, saving the company's financial resources, material resources and time;
4 Excluding the influences of substrates, printing press status, printing environment, printing pressure, and printing speed, and solving various problems brought about by printability;
5 The customer has established a basic color ink database for data exchange with the CFS ink color matching system; as long as the wavelength is 390 ~ 780nm Akiyama International, regardless of any brand of spectrometer can be connected with the CFS ink color matching system. History of development
To test the accuracy and reliability of the CFS spot color ink dispensing system, R&D personnel of the China Printing Science and Technology Institute specially visited Shenzhen Yachang, Guangzhou Xinhua, Shanxi Chengong, Shanghai Jielong, Hangzhou Zhongliang Packing, Beijing Baodao Packaging, Beijing Jiaxinda and other printing companies put forward many negotiating opinions and expectations on the ink distribution system, which promoted the upgrading of the product.
