First, there is no machine that looks more complicated than a folding machine. Second, when the paper runs through the machine, the speed is so slow that even a pair of amateur eyes can catch the moving paper. From these current conditions, can the printers still not see the potential of post-processing operations? "Most companies are busy researching prepress systems and ignoring the postpress process, which makes the post-printing process a bottleneck in the entire printing process," said Tony HardS of the printing equipment company.
Heidelberg also has the same view. CIP3 (combination of prepress, printing, and postpress) was actually reflected in the process from prepress to printing, and the time spent in printing to the postpress process was long and could not achieve the same degree of acceptance. This is mainly due to the different styles, materials, and other factors in the subsequent process.
However, the pace of progress toward integration will not stop. In today's society, it is not enough to solve problems in a simple way. Although the importance of post-processing in all aspects of printing is obvious to all, ordinary post-processing machinery is gradually decreasing. As Setmaster's Paul Bailey said: “For printers, finishing a product's processor is much more important than the price of this product, but if the price of a product is a decisive factor, so many printers Why can't I integrate post-process control into my computer?
The main reason for integrating post-process control into computers is to control quality and delivery time, and if printers continue to add processing equipment, investment in equipment and saturated business volume will limit the increase in production efficiency. exactly. "He said.
Bailey's conclusion gave us a silver lining; "There is no need to worry about ordinary post-processing equipment because the large amount of work that is produced from the printing press requires subsequent processing. This is why we designed DuoMotion. It is a two-way device. Page machine, can carry out two groups of job production at the same time.
“Printers will continue their efforts to integrate processes, which is a major event,” he quoted the Scottish newspaper printer Macdonald Lindsay Pindar, who purchased the first DuoMotion collator for 16-page tabloids. Match page.
Obviously, due to the use of computer input information, the folding machine can debug the machine faster and at the same time greatly increase the operating speed. MB was the first machine to introduce computerized folding technology. At the Ipex98 conference, Shoei introduced the first large-format computerized folding machine. "Computerization made it possible to achieve high yields because the physical speed of the paper through the folder was fixed, saving only the time it took to debug the machine," explained Mike Biggs of Smyth-Horne, who had previously promoted Shoei and MB machines in the UK.
"Overall, on the UK market, the share of Buckle and Combination Folding Machines each account for 50%," said Chris Fewings, who is responsible for the post-processing equipment market at Heidelberg. “However, the sales volume of Buckle Folding Machine accounts for 80% of the paper handling B2 and less than B2 size paper. For B1 Paper, combination folding machine is more popular because it saves space and requires different structure. Format features." He said that in the UK, Stahl holds more than half of the folding machine market. "The speed of the buckle machine is about 230m/min. The speed of the combined folder is 180m/min. However, for some large format products, the combination folding machine can still compete with the buckler."
All people agree with this view: The trend in the future is to make it possible to minimize the time spent and increase the speed of operation through a short process. According to GHE's Brian Mickels, “Processing equipment after use often requires experience and skill. These techniques become unnecessary factors in the transition from subjective/repetitive operating environments to digital printing operations.
In the new printing technology, the paper size, quality, and the pressure exerted on the paper, etc., these parameters are set to help solve the difficulties encountered in the post-processing paper when subjected to large changes. "(To be continued)
