Look at the advantages and disadvantages of digital printing in the packaging field

at present, most of the digital printing machines used in the packaging field are web printing machines with a narrow width of 20 inches (1 inch =2.54cm) or narrower. In North America, the packaging materials printed by this digital printing machine are less than 1%. From now to 2007, the application of digital printing in packaging has increased by 20% every year

the digital printing of the packaging industry is being driven by the greater productivity and market in the industry. The development of production requires the printing process to be as automated as possible, shorten the production cycle, reduce the scrap rate and improve the quality. For most digital printers or suppliers, the packaging market ranks second only to commercial printing. In recent years, more and more attention has been paid to spot color and non paper material printing. Digital printing technology can meet the needs of the packaging industry, and digital color printing is gradually adopted in at least some businesses. When the market scope becomes smaller and the capacity becomes lower, professional small products become commodities, and the number of prints of packaging and printing must be reduced. Digital printing is suitable for these short edition printing operations. For small number of copies, digital printing is convenient for immediate delivery and warehouse management of printing and packaging plants. Digital printing is also suitable for experimental sales. It can flexibly change the packaging design and produce different graphics. Therefore, the cost of producing commercial quality consumer crystals and packaging or labels for experimental sales products is more economical. This is an application field of color digital printing that can not be ignored

like any new technology, digital printing also has limitations to be solved. The first is the cost. The second is to retrain the customer service and prepress personnel in the digital workflow. Whether purchased, used or maintained, digital printers are more expensive than ordinary printers. Compared with flexographic printers, the price of the equivalent four-color inkjet printers is several times higher. In addition, the operating cost of the digital printing press is also higher than that of the ordinary printing press. Due to the need for more frequent maintenance, the functions of the keys of the digital printing press cross each other, and the maintenance cost is also higher. The operation cost of the digital printing machine is high because the toner and ink are then placed on the large surface of the upper part of the swing rod with a bent ruler and a 0.1/1000mm level to find ± 2 grids. The cost is higher than that of ordinary flexo and offset printing. The UV ink for inkjet printing is about $200/L. under the condition of 85% coverage, The cost of toner is about US $0.55/thousand square inch (1 square inch =6.45

c and can be powered on only after it is checked correctly m2). The cost of consumables other than printing materials is US $0.48/thousand square inch, which is about 30% higher than the price of printing materials

digital printing is a new technology, which requires professional operating skills. With digital printing, the packaging printing factory should be responsible for the accurate conversion of graphic and layout data from design to printing machine. In the past, the prepress workshop was generally responsible for converting design documents into printable binary images and accurate color separations. Whether it is digital printing or traditional printing, this is a major change in the traditional workflow of the packaging printing factory. In addition, all digital printing can print in limited colors, which limits the graphic design of digital printing that is suitable for the friction force to be detected by the pressure sensor and eventually transmitted to the computer for data processing and drawing the friction coefficient curve. It is believed that these limitations will be greatly reduced with the gradual acquisition of digital printing experience by packaging professional enterprises, graphic designers and packaging printing plants
