Since ancient times, printing innovation has always been a major issue affecting social progress. In the Northern Song Dynasty more than 900 years ago, Bi Sheng invented movable type printing. The printing efficiency was raised several dozen times at once. About 400 years later, German wine connoisseur and metallurgist John Gutenberg borrowed from the wine industry. Similar machinery, the invention of metal type printing machine, this method quickly spread throughout Europe; into the late 20th century, information technology in the field of publishing and printing has brought a new revolution in the "say goodbye to heat and fire, to light and electricity" tide Among them, the computer laser phototypesetting system has become a new industry standard. In recent years, with the increasing popularity of Internet-based content creation and distribution, publishing technologies with full personalization, flexibility, and popularity have received increasing attention from publishers and customers, and a revolutionary digital printing technology has gradually become more and more important. Surfaced.
HP Lab (HP Labs), located in the hinterland of Silicon Valley, is one of the most influential high-tech industrial innovation centers in the world, and is currently the most concerned digital printing technology promoter. According to HP Lab scientists, there is a fatal problem with existing publishing printing systems. This is the lack of efficient integration between prepress technology and printing equipment. Desktop-centric prepress systems and press-centered printing systems. The printing equipment is in its own right, bringing double losses of efficiency and manpower. On the one hand, because there are two links between “design†and “printingâ€: “shooting out†and “proofingâ€, it is difficult to avoid the waste of manpower and material resources, especially in the proofing process. The calculation of paper and ink will inevitably lead to high costs for small batches and individual printing. On the other hand, the current results of filming and proofing must be identified and manually adjusted by human eyes. The experience and ability of personnel will have an effect on the final results. Has a direct impact, which also affects the popularization of printing technology.
In order to overcome these problems, HP Lab has invested a lot of resources in digital printing technology and integrated the advanced technology of Israel's Indigo company acquired in 2002, which has enabled HP Lab's world-leading prepress workflow and Indigo digital presses. Seamless connection. With the help of HP Lab's successful liquid electronic inks, digital color offset printing, color management, electronic imaging and many other innovative technologies, anyone and businesses can become paid digital printers. Compared with computer printing, digital printing has higher quality; digital printing has higher flexibility than traditional printing. Any brilliant design done in a computer typesetting system can be output from a digital printing device with no difficulty. The first page printed is a qualified finished product without any waste or artificial color correction. Users can realize the combination of variable data printing capability and offset quality through 7-color digital printing technology that does not require filming. This improves the printing company's work efficiency, reduces resource consumption, and eliminates the company's dependence on human experience. This new technology has the flexibility and price advantage to provide high-quality personalized printing services to help customers develop new business opportunities.
In HP Lab's blueprint for digital printing development, digital printing technology can be integrated with the Internet without any eclipse, creating a global on-demand printing production and service system that spans time and space. It may not be long before we can provide on-demand services for print, publications, packaging, cards, trademarks, photos and other products anywhere, at any time.

UPVC door, also known as unplasticized polyvinyl chloride door, is a type of door made from rigid PVC that does not contain any plasticizers. UPVC doors are popular for both residential and commercial applications due to their durability, energy efficiency, and low maintenance requirements. Here are some key features and benefits of UPVC doors:
-
Durability: UPVC doors are highly durable and resistant to impact, weathering, and corrosion. They are not prone to warping, rotting, or rusting, making them suitable for various climates and environments.
-
Low maintenance: UPVC doors are virtually maintenance-free. They do not require painting, staining, or sealing. Cleaning them with mild soap and water is usually sufficient to keep them looking clean and fresh.
-
Energy efficiency: UPVC doors have excellent insulation properties, helping to minimize heat loss or gain. They can contribute to better energy efficiency in buildings by reducing heating and cooling costs.
-
Sound insulation: UPVC doors offer good sound insulation, helping to reduce external noise and create a more peaceful indoor environment.
-
Weather resistance: UPVC doors are designed to withstand various weather conditions without deteriorating. They are resistant to moisture, UV rays, and extreme temperatures, making them suitable for both interior and exterior applications.
-
Security: UPVC doors can be equipped with multi-point locking systems, enhancing security and providing peace of mind.
-
Customizable options: UPVC doors come in a wide range of styles, designs, and finishes. They can be customized to match different architectural styles and personal preferences.
-
Environmental friendliness: UPVC doors are recyclable, and the manufacturing process of UPVC typically consumes less energy compared to other materials like aluminum or wood.
It's important to note that UPVC doors may have a different aesthetic appeal compared to natural wood doors, as they have a more modern or contemporary look. Additionally, UPVC doors are generally used for exterior applications, although they can also be used indoors. Choosing high-quality UPVC doors from reputable manufacturers and ensuring proper installation and maintenance will contribute to their longevity and performance.
