Web printing custom print processing case analysis

The sound development of the European advertising market in 2001 has prompted many manufacturers to invest heavily in large-volume web offset presses, especially in Italy. But in the following two years, the economic situation has been poor, which has also brought about a slowdown in investment. However, by the last quarter of 2003, it can be seen that there has been a technological investment in the publishing and commercial rotary printing sector. Improved.

It is expected that from the second half of 2004, the economic recovery will show the most optimistic prospects, and the advertising market will also see a new slump, which once again stimulates investment. Nowadays, manufacturers pay more attention to high-efficiency, high-speed, high-performance devices. They also focus on tailoring solutions for different users to make themselves more competitive in the European market. Multi-page and high-speed web presses, coupled with fully automated and custom post-processing solutions, provide users with maximum flexibility, production speed and quality.

In order to better serve the market, large-scale printing factories should have a variety of production capabilities, so that they can respond flexibly to the different needs of customers and maintain their competitive position. Therefore, today's rotary printing technology should be able to process a wider range of products (including magazines, catalogs, advertising prints/inserts, name directories, books, etc.), as well as different formats and pages (from four to 96 pages and More pages) products.

Suppliers who provide post-press equipment for the European rotary printing market should have the ability to meet a variety of highly flexible and personalized solutions to meet different (or special) production types and page configuration requirements. In addition should provide:

Highly automated level

Efficient production and high-speed solutions

Equipment and service/personnel reliability

Efficiency - low production costs and low waste (drop to 0)

Civiemme S.pA. of Italy is an industry-leading company that specializes in providing complete and custom-made post-press equipment solutions for rotary printing equipment. Civemme has been designing and manufacturing stackers since 1975. At the same time, Civiemme also aims to meet the special needs of different markets, mainly for the European and North American markets, for them to customize personalized solutions. During these years, Civiemme has introduced various types of products to meet the needs of rotary printers.

The production speed of rotary presses is generally more than 40,000 cph. Since 2001, Civiemme has installed 40 post-press equipment systems on the European market to handle the output of 64-page rotary presses, and the company has also sold the same amount. The post-press system is used to process the 48-page press job output.

Here are some examples of printing vendors:

European Market Case Study

Pozzoni, Italy

Pozzoni Group is a leading domestic printing company in Italy. Recently, it has added three new Roland Lithoman IV 64-page presses to expand its web production capacity by 60%. At the same time, Civiemme’s latest solutions are also used. Bookpost disposition. The company's goal is to further improve processing capabilities and grow into the leading printing company in Europe.

These imported rotary presses are mainly used to print catalogs, magazines, and advertising products in different formats and pages. The Lithoman press will be installed between mid-2004 and mid-2005.

Civiemme's equipment will simultaneously handle the product stacking and signature classification of each of the four delivery units (two magazines, one tabloid, and one DP) for each press. Above it is a transmission system with steering gates and job stream conversion structure to change the direction through which the printed paper can be transferred to Civiemme's postpress facility.

Both Lithoman presses will also have the same post-press equipment solution installed. Many processed products, such as leaflets and advertising products, will be trimmed by the RT 550 rotary cutter for three to four sides. The cut product is then stacked by the CS 350 Compensating Count Stacker. The piling machine is equipped with a special slot compensation device to ensure continuous and smooth transfer of the job flow to the above positioning area, where the prints are piled up. On the CS 350 delivery system, the electronic module unit (BU350) can very loosely pile up the paper stack, and then manual or automatic palletizing can be done so that the quality of the printed product can be maintained perfectly, and tapes can also be avoided.

Book-bundling uses a different stacking solution consisting of two ST 420/120 baled stacking devices to form a 1200 mm thick book bundle. This stacker is designed for fast web printing equipment and can quickly produce book bundles in seconds. In Pozzoni, the stacker is also equipped with a fully automatic double baling system: when the first baling unit breaks down, it is automatically started as a back-up second baling unit, guaranteeing a good packaging process and production The continuity of the process.

The bundles from the two ST 420/120 bale stackers and the book stacks from the CS 350 offset stacker will be sent together to a single stacking unit: PL-Robot 250 . This stacking robot is installed with other equipment for the production of fully automated stacking processes, including tool conversion and clamping for books and bundles. The PL-Robot 250 has a speed of stacking 144 bundles of books per hour and 800 bags per hour.
