Komori has shown an eight-colour version of its redesigned SRA1 Lithrone 37 at Igas, the Tokyo show taking place this week.
The press will be positioned to challenge the popularity of the RMGT 9 LED UV press which has been one of the worldwide best selling machines in recent years. The original Lithrone G37 was not offered with a perfecting unit. This was shown at Drupa 2016, the only Komori at that show with LED UV.
Since then the G37 has undergone a redesign and includes a new style perfecting drum offering no changes in gripped edge when perfecting. The surface of the perfecting cylinder is flat, so eliminating the risk of scratching during the sheet turning process. The press is rated at 15,000sph.
The new press is one of three Komoris with LED UV on the Igas stand as the company switches focus to the digital curing technology. At Drupa two years ago single-lamp H-UV was in the ascendency. At Igas only the entry level four-colour G37 has this drying unit. The other three presses are designated as H-UV L (LED) drying.
This includes a tandem perfector Lithrone GX40RP running at 18,000sph. This is demonstrated with fast change between three jobs, one a ganged up job that is finished immediately on a Komori Apressia guillotine, another a catalogue section. Asynchronous plate changing and PQA-S print quality assessment, register and colour control with connection to the KP-Connect Pro network production hub deliver a press designed to cope with short runs.
The third press with LED UV is a six-colour Lithrone GX40 with coater set up for high speed carton printing, again running at 18,000sph. This includes a parallel makeready sequence for close to lights out printing using Autopilot for nonstop printing. A PDF comparator and sheet numbering system to identify those with defects is included.
The coating unit is new and has four anilox rollers in a cassette unit for an automatic switch over between coating cylinders.
The litho presses are supported by the B2 Impremia IS29 UV inkjet machine and the Impremia C101, a press that Konica Minolta has supplied under OEM terms. There is no NP40, the Komori press using Landa’s nanography technology.
The company is showing an extended portfolio of Apressia finishing equipment, adding the Apressia CTX132 guillotine, the DC105 flatbed die cutter/creaser and MB110E blanking units. There is no guarantee that these machines will be distributed in Europe.
All are configured to operate with KP-Connect cloud based automation engine which controls the flow of jobs and tracks progress while delivering set up data directly to the relevant piece of equipment. This is integrated with Screen’s EquiosNet prepress workflow, a first partner in the KP-Connect alliance programme to open connectivity with MIS, prepress and post press operations.
Komori has to date connected almost 250 machines through KP-Connect, with a broader roll out planned.
Komori has redesigned the Lithrone G37 to include a perfecting version of the SRA1 press to match demand for the format from commercial printers looking for a value for money press with the latest technology including LED UV drying.
