RMGT 790 PRODUCT INFORMATION
The demand for high-mix, short-run, fast turnaround, high value-added printing is driving the daily workflow toward high levels of complexity and specialization. The diverse specifications of different jobs makes printing processes more difficult to manage. Also, there is a need to employ special techniques and effects to differentiate sales materials for added impact.
The RMGT 7 Series press offers the exceptional reliability and advanced features needed to respond to this trend. With advanced automatic systems that shorten make-ready time and high-speed printing at up to 16,000 sheets per hour*, these high-performance offset presses boost productivity and optimize production efficiency for diverse short-run printing. The RMGT 7 Series press delivers top performance for a wide range of printing work, providing crucial support for success in a competitive market.
* The maximum printing speed of the RMGT 7 (790PF model convertible perfector) is 15,000 SPH.
Shorter Make-ready Time
Various automatic systems and labor-saving functions shorten make-ready time. The key to higher productivity for diverse short-run printing is shorter make-ready times. With Program Inking for quick and easy color setting, an automatic plate changing system and automatic cleaning devices, the majority of make-ready work is fully automated.
The SPC semiautomatic plate changing system comes as standard and allows plates to be changed quickly and accurately. The operator merely sets the plate on the positioning pins and presses the button for plate changing. Plate changing can be automated with the Smart-RPC* fully automatic simultaneous plate changing system or RPC* fully automatic plate changing system, which can be combined with Smart Make-ready functions* so that blanket cleaning, preset inking, and test printing are also performed automatically for even greater work efficiency.
The pre-press data is analyzed by the PPC Server III (or Ink Volume Setter)* to calculate the image area ratio. Based on the image area ratio data, the PCS-G print control system automatically selects the conversion curve for each color, sets the opening of the ink fountain keys and controls the ink rollers.
The PPC Server III is for CIP3/CIP4 (PPF) compatible pre-press systems and the ink. Volume Setter is for PS compatible pre-press systems.
High Quality, High Precision and Durability
A printing press is comprised of many different mechanisms and components. Print quality depends on their precision and quality. Press mechanisms with micron-level precision ensure consistent print quality and excellent color reproduction. Strong, durable, high-precision construction is key to maintaining uncompromising print quality over long years of use.
The R-matic continuous dampening system assures a uniform supply of moisture on the plate surface to reproduce sharp dots, glossy solids and finely detailed text. This system also allows for non-alcohol printing. It is easy to switch between integrated-mode and separated-mode from the touch-panel in order to exactly match the image and characteristics. The R-matic-d* continuous dampening system with remote ON/OFF hickey removing function greatly reduces hickeys on plates by using a drive mechanism for the water form roller creating a rotational speed difference between the water form roller and plate cylinder.
Response Capabilities – Meeting Diverse Needs
The RMGT 790 model is equipped with a V-type feeder, the same high-speed, high performance feeder as RMGT 10 Series presses. From thin sheets to thick cardboard stock (straight printing models only), sophisticated air management technology ensures each sheet is precisely fed even during high-speed runs.
(The V-type feeder’s minimum sheet size is 11.41” x 16.14” (290 mm x 410 mm). An original type feeder option is available with a minimum sheet size of 7.87” x 10.98” (200 mm x 279 mm.)
Switching between straight printing and perfecting is performed by remote control on the touch panel display of the PCS-G print control system. The operator inputs the sheet size and printing mode and then simply presses “Start”. The open/close timing of the convertible perfecting device grippers, the various cylinder phases, and the position of the vacuum hold down device are automatically switched in less than 2 minutes with no need for tools, greatly shortening make-ready time.
Double/double/single-diameter cylinder perfecting mechanism*
*Single/double/single-diameter cylinder perfecting mechanism is standard on a 2-color to 6-color presses. A double/double/single-diameter cylinder perfecting mechanism is available as an option.
Integrated Management – Advanced Quality and Production Control
MIS connection software*1 connects a CIP4-JDF compatible MIS (management information system) and a compatible press*2 for real-time printing process management. The software also enables real-time exchange of CIP4-JDF format data on job instruction (job name, number of sheets printed, sheet size, etc.) between the MIS and PCS-G. The Print Job Manager*1 press operation control system connects compatible presses*2 via a network to manage the production schedule and transmit printing job data. It also collects on press operating status in real time and automatically generates production analysis data.
*2: Compatible presses: RMGT 9, RMGT 7, RMGT 6, RMGT 5 (520GX model)
High Value-added Printing
LED-UV Printing System*
RMGT is the first press manufacturer worldwide to offer LED-UV curing systems for commercial-scale sheet-fed offset printing. RMGT continues to lead the industry in this area by improving and developing its curing system featuring outstanding environmental performance.
Power consumption of the LED-UV curing system is only 10% that of a conventional UV lamp system*. Also, the need for standby power is eliminated by the instant on/off of LED-UV lighting, providing substantial energy savings.
*for the 790 model.
A conventional UV lamp system’s light source lasts approximately 1,000 to 3,000 hours*, but the LED-UV system’s light source has a long life of approximately 15,000 hours. Therefore, a conventional UV lamp system remains lit in a standby mode during make-ready work, shortening its life, while the LED-UV system remains completely off so light source life is unaffected.
* Life span will vary according to usage conditions such as frequency of being lit/unlit.
The growing popularity for the LED-UV curing system has led to a wider selection of inks, varnishes and substrates. Various types of high value-added printing can be performed using different press configurations and materials, including varnish coating and printing on special substrates.
*Drying performance will vary according to the type of substrate, ink, varnish, curing unit, print speed, etc.
