Every four years, printers are all over the world gather in the German city of Dusseldorf on the unique 'Olympic Games' – a competition the latest advances in printing technologies, materials and equipment – show drupa. The general impression of the exhibits presented at the May of this year the exhibition, digital (computer) technology are the dominant trends for the new generation of machines produced by leading firms of printing machinery such as Heidelberg, KBA, MAN Roland, Komori and other biggest exhibitor at drupa was a firm Heidelberg, which exhibits occupied two pavilions of seventeen. The firm provided all kinds of printing techniques – from publishing to bookbinding, for all types of products – newspapers, magazines, books, posters, labels, packaging, etc. The actual print has been focused either on the classic offset presses (from small operational Printmaster QM 46-2 to high newsprint Sunday 3000/32), or on digital presses that work of Technology computer-to-print (Digimaster E150, Digimaster 9150i, NexPress 2100) and computerto-press (Quickmaster DI 46-4 Pro , Speedmaster SM 74 DI). Laser Technology, also based on digital information, are used firm as in equipment for prepress (technology Somputer-to-Plate, implemented in imagesetters Suprasetter 74 and Suprasetter 105), and in the above-mentioned digital presses and large format printing. It should be noted that if the early development of digital offset presses from Heidelberg based on laser recorders American company Presstek (Quickmaster DI 46-4) and the Canadian firm Creo (Speedmaster 74 DI), then the new model Speedmaster SM 74 DI (presented at the exhibition only one printing unit) were applied laser heads his own production, are already used in imagesetters type Suprasetter (ill.
To move from one edition to another) thanks to fully automatic simultaneous change of eight forms of management and computer tuning machines for printing. Actually the process of print circulation lasts less than two minutes at a speed exceeding 10 m / s (60 thousand copies. / H). With such fast-moving process of replication products practically does not interfere with a person in control of the seal and all adjustments are made by automatic control systems.
Another Japanese firm, TKS (Tokyo Kikai Seisakusho), showed an even higher speeds (over 90 thousand copies / hr.) printing 12-page newspaper format 533h318 mm, carried out by car Color Top 9000CDH. Print quality is automatically controlled by a system of Web Viewer INS-300R, which are installed sensors between the tower printing units (4 +4) and folding the paper web to view the full width (1900 mm). In addition to the dynamic densitometers and spectrophotometers, mounted directly on the printing machines, a number of firms decide the task of visual inspection of prints in the printing process, using for that purpose digital cameras. Thus solves the problem of the CPA firm on an offset sheet printing machine Rapida 105. Manufacturer Windmoller & Holscher 10-color flexographic car Novoflex CM (ill. 5) Set the video system BST webscope, which gives a unique opportunity printmaker efficiently control the output to print ‘from the roll to roll. ” Manufacturer Fife-Tidland GmbH offers video-paper web system InPrint Video Web Inspection (Ill. 6), which can be installed on any printing press, including large format printing.
Among the latest digital printing should be noted the development of the recently combined their efforts firms Hewlett-Packard (USA) and Indigo (Israel) – roll digital printing machine hp Indigo press w3200. The machine works on technology transfer hp ElectroInk with ink on paper on the principle of non-impact (no pressure). In this class, it is one of the most productive – 8 thousand copies of A4 per hour full color printing on the face and turnover. Since the machines of this type is a possibility of printing variable data, in conjunction with the finishing line of the Swiss company Hunkeler, make cuts and cutting fabric, collation book block up to 250 mm thick (technical limit), this complex turns into a print-Collator unit, able to produce finished products in the form book blocks. Blocks can be immediately sent to the bookbinding line. Of the exposed samples of the new bindery finishing equipment differed line German company Bielomatik, capable of using a digital control system to carry out simultaneous processing and Finally, the hardcover book blocks from different runs.
