Manroland's multi-color double-sided printing press adapts to the needs of customers quickly

At present, the competition in the printing market is very fierce. Printing companies often have to complete printing tasks in a short period of time so that they can deliver on time. If you need to print on both sides (this is required for most prints), the multi-color set of double-sided printing presses is the preferred choice for printing companies.

Although print buyers demand shorter and shorter delivery times, their demands for print quality are getting higher and higher. In this case, a multi-color group double-sided printing press is particularly suitable for commercial and publishing printing companies having an industrial scale. So what advantages and benefits does the multicolor printing unit bring us? The answer is: While printing companies can greatly reduce delivery time, they can make flexible and strategic adjustments to their product lines. The multi-color group double-sided printing machine can complete the seven-color or eight-color printing in the direct printing mode.

Inline duplex printing unit - more production time, shorter print job preparation time

The decisive factor in the use of in-line duplex printing devices is the availability of printing machines. In deciding on the economic feasibility of investing in an inline duplexer, the printer should first carefully calculate the machine utilization based on the expected number of print orders. If its utilization rate is very high, the advantage of the multi-color group double-sided printing machine will be very prominent: the production and printing cycle will be shortened, only one printing job preparation and one washing process will be needed; the final printing finishing process can be carried out earlier. The customer can also receive the goods earlier; since there is no need for an additional printing process, procedures such as de-powdering, intermediate storage and stack turning can be dispensed with.

All printers hope to increase the ratio of production time and print job preparation time. A printing machine equipped with an inline duplex printing device can perfectly achieve this: it only needs one printing process instead of two, which greatly increases the printing process. Reduces drying and waiting time. For example, printing a 5/5-color 32-page booklet on a ten-colored double-sided printing press would save about 30% of the time on a five-color direct-printing press.

Saving time is important, but the advantages of an inline duplexer are more than that. The printing quality must meet the customer's ever-increasing requirements, and Roland's in-line double-sided printing device ensures this. The first condition for precise front-to-back registration is the high stability of the entire mechanical system. Roland's in-line double-sided printing device equipped with dual-diameter paper reversing rollers, in accordance with the delivery speed of the paper, ensures high quality and the most accurate front-to-back registration of the printing. . In addition, the flattest paper delivery path, minimal paper transport, and pneumatic paper guidance system ensure top-notch print quality. Any blemishes will be removed, and the high degree of stability of the mechanical system ensures a high level of accuracy.

OptiPrint Roller Sheath - Ensures consistent print quality on both sides

Is it positive or negative? Today, this issue has been difficult to answer. Because now advanced printing technology can ensure that the printing quality on both sides is consistent. With Roland's in-line duplex printing unit equipped with an OptiPrint cylinder sleeve over the impression cylinder, consistent print quality can be ensured on both sides. The OptiPrint roller sleeve developed by Manroland is a textured plate with a special ink-repelling surface. Now, with the development of the latest industrial materials, the second-generation drum jacket has also been further improved.

Printnet job management technology significantly reduces preparation time for print jobs

Printnet job management technology combines sales, desktop publishing, prepress, printing, and postpress printing production processes into a complete workflow. The interaction of each printing step and the highest utilization of the printing machine will increase productivity. For example, the integration of an automated impression cylinder washing system and Roland's quick-change setting in the entire printing process minimizes the preparation time for the print job, thereby greatly improving the production efficiency.

Advanced printing technology greatly reduces preparation time for print jobs

The various automation features of the Manroland Sheet Press ROLAND 700 also give us a lot of additional benefits. The conversion between the direct printing mode and the double-sided printing mode is fully automated. It takes only about 2 minutes. , And this time has included any necessary adjustment of the printing length.
With the fully automatic APL loading and changing system, the time required for changing versions is shorter. Each printing unit only takes less than a minute and does not require the printing operator to supervise it. When a change is needed, the printer can use this time to do other tasks, such as preparing the next job. In addition to speed, the system automatically controls the position of the plate during the loading process, ensuring the position of the plate is correct and the accuracy of the registration begins. The rear clamp is divided into seven sections, mainly for the registration adjustment at the end of the paper. This is particularly important for stretched sheets.

In addition, the automatic washing system provided for the ink unit, the blanket, and the impression cylinder can also shorten the preparation time for the print job. The automatic impression cylinder washing device can be installed on the ROLAND 700. The washing brush can effectively remove the dirty things on the surface of the impression cylinder. The washing process can be performed at the same time as the cleaning of the blanket. The automatic ink roller cleaning device will use different washing procedures depending on the degree of dirtyness. The cleaning supply system with four independent circuits for the washing unit allows the traditional inks and UV inks to quickly interchange with each other, which is exactly in line with the requirements of many printing companies.
