Digital technology in gravure before printing, and application of high performance field of digital gravure printing machine is the constant improvement and development makes the gravure printing folding carton quality can reach the level of the offset printing, and cost is low many.
The application of digital technology, promote the gravure printing technology development, especially in folding carton, carton of drum field gravure printing quite fast development, more and more people have accepted and used to replace paper box, a single mode of production momentum. Soft printing technology in the new breakthrough sleeve new development, in the control network and network expansion rate has a profound meaning, greatly improving the gravure printing quality. The new digital without shaft gravure production line (not always not synchronous belt, axes, and without the introduction of roller gear) to some extent, also promoted the gravure printing quality improvement. At present, flexo folding paper boxes product quality has reached the most basically offset printing corresponding the quality standard of the product.
Market research and results
Recently, someone to the north American 250 household folding carton gravure printing company for a market investigation, the results show that: the leaflet materials processing way will present to decrease: the market share will shrink from 63% in 1990 to 51% in 2000; Drum materials on-line processing (including gravure printing mode and offset printing) would be a great way of growth, market share from 35% in 1990 to 47% in 2000 to expand. Gravure printing market continued to decline in 1990, accounting for 15%, and market share for 2000 years to drop to 10%. The research also shows that: because the gravure printing market share in the 1990 to 2000 these ten years will double (from 8% in 1990 to 16% in extended to 2000), therefore, even if the market share of the drum offset in the 10 years doubled, from 10% to 20%, and the total market share folding carton offset printing is still a descending trend, the will, down from 75% in 1990 to 70% in 2000.
Industry change
Folding carton of European market survey and analysis indicated that the folding carton industry is in a crucial turning point, is from the previous wide, pamphlet, gravure printing and traditional, simple gravure printing, high automation, adaptability to more strong, the production capacity of the higher the narrow without shaft drum soft printing way conversion. Poll, recently, because the introduction and application of flexible digital without shaft rotary die cutting system, set the cutting and creasing, bump trims, etc DuoZhong process in a body, the many working procedure can be a complete, and greatly reduce the production cost.
The early drum folding carton of production line adopts using die cutting equipment, is due to adjust the time machine long, poor stability of reason, production speed is low, cost and efficiency in the leaflet and new hard to type production line to legitimate.
Today's gravure die cutting system is greatly different, performance has improved greatly, and it USES is the rotary type die cutting equipment, width to a maximum of 55 inches (1400 mm), the highest can reach speeds of up to 1200 feet per minute (400 m/min). At the same time, it also has the "rapid change a" device, can quickly change to the cutting of the damage. Some systems also has no gear lifts device, can speed processing complex layers of nested folding carton semi-finished products. On-line rotary type die cutting of another advantage: mold range of options more more widely, especially without shaft mould and surface mold, the price is very low, compared with the traditional short edition box production for the market, single strong competitiveness.
The integration of the paper box within the industry will continue, and industry competition will be more intense. With the new drum folding carton of production line of put into use, will impact the folding carton processing factory and existing folding carton printing houses, there will be some folding carton processing, especially enterprise be eliminated.
Research conclusion
Digital pre-press techniques and digital printing machine technology revolution, will give the gravure printing process to bring new life and vigor, and the application of new technology, will continue to improve, improve the level of production operating performance, therefore, has the very high return on investment sex.
But, for all sorts of different types of drum gravure printing production line, should seriously analyzes its investment amount and production efficiency the contrast between the balance, choose the most suitable performance/price ratio of the equipment, it is very important. The new all-digital drum on-line processing multi-function gravure production line, mostly with rotary cutting device and creasing device or rewinder device, speed, to change a fast, therefore, reduce labor intensity, reduce scrap rate, the production efficiency is improved, more investment value.
