The progress of the printing press has brought the speed of sheet-fed offset printing to a new level, and the operation has also become simpler. However, the printing of packaging cartons has been unsatisfactory. What are the challenges faced by sheet-fed offset printers? What kind of solution does the manufacturer of the press have to offer to adapt to those paperboards that are difficult to handle?
Challenge 1: Diversifying Substrates
Four years ago, the Hammer Lithograph printing company in Rochester was only able to print on paper. The customer and market requirements motivated the company to move in a newer and broader direction, and they decided to enter the BOPP material field. Now Hammer prints its single BOPP material on their Mitsubishi presses, including a 56†machine and a UV ink printer. They use a dedicated parameter program to control the operation of the press and use the single BOPP material. In high-end printing jobs.
Mitsubishi's presses for printing paper plates use a heavy-duty paper guide system to prevent scratches and smudges on the surface of the paper plate. COMRAC (Central Operations Job Preparation and Console) uses only 1/3 of the paper. Normal printing preparation time to adjust the thickness and size of the substrate.
In order to determine if the substrate is working properly and to define the mechanical properties of the press from a statistical point of view, Mitsubishi recently introduced a third-generation DRA (digital registration analysis) service. The DRA2000 provides some metrics to printer buyers and existing users, typically in the micrometer range, enabling the precise positioning of sheet-fed operations between each unit of the press, followed by the determination of standard deviations and reduction of deviations. Make the necessary adjustments.
Challenge 2: Water and ink balance
The balance of ink and wash during the printing process determines the quality of the entire product. The fine wetting balance system was successful on the Man Roland 900 press. The complex ink supply assembly is responsive and provides a stable ink supply. It is used with Roland's Deltamatic dampening system to eliminate ring-shaped white spots on the plate.
Mitsubishi also paid attention to ink ink problems. The Delta dampening system they developed maintained a consistent wetting fluid supply throughout the entire printing run.
Challenge 3: Automatic Integration
Riverwood International, Inc. is a company that produces transfer products for beverage packaging and expects to shorten the lead time for printing jobs. Recently, the company replaced the original two old presses with a seven-color KBA Rapida 142 press, which was due to the shortened preparation time.
With a maximum speed of 14,000 seconds per hour, this model has a fully automatic plate change capability, greatly reducing print preparation and downtime. In addition, although the CTP system has not yet been adopted in the factory, it has also been prepared for the company because the Rapida press has CIP3 compatibility.
Most users are more concerned about productivity improvement. KBA's printing presses have been automated in every process that requires operators to spend time and energy, including automatic cleaning of blankets and rollers; automatic setting of size and pressure; automatic Ink path adjustment; and closed-loop density or spectrophotometric detection system. This series of automation has greatly improved production efficiency and is also an economic return that can be obtained by upgrading equipment.
Komori also focuses on automation and integration with a keen eye. The printing presses it produces have historic developments, featuring digital open architecture networks (DoNet) for color management and process control.
Lithrone recently developed a new Lithrone 20, using a LCD display to adjust the ink balance, adjust the ink/water flow rate, and register during the printing process, including side-to-side register movements and rollers. adjust.
Printing integration is not the trend, but also the most important task in the industry: to integrate the entire production process into a digital workflow and automated material flow. Heidelberg's new CP2000 control center processes the data directly and passes the data directly to the printer for printing via the prepress interface.
Heidelberg also realized that the process of carton production must be automated in order to be profitable. In order to reduce the labor force, Heidelberger has improved the Logistics automatic material transfer system of the Speedmaster press. They use an automated roller transport mechanism to move the metal plates and stack them automatically, reducing manpower and material resources.
