Comexi Shows Latest Innovations in Offset Printing Technology

Comexi, specialist in solutions for the flexible packaging industry, presented its latest innovations in its revolutionary offset printing technology: the Comexi CI8. The group recently held an open house – dubbed “Offset Innovation Day” – at its headquarters in Riudellots de la Selva (Girona, Spain).

During the event, Comexi demonstrated the latest evolutions that Comexi’s offset team has been developing in the past year. Main improvements were done in efficiency and productivity. For example, the cylinder service station has been directly integrated with the press and with the sleeve-handling robot. This improvement allows fast check of mounted plates and blankets and fast replacement, if required. Furthermore, during the event, were also presented improvements in costs savings in web handling, upgrades in color matching and color management with QuadTech technology and the possibility to group different designs in one print job.

The meeting was open for worldwide clients and convertors. In fact, more than 60 brand owners, managing directors, CEOs and technical experts from different companies witnessed in first-hand the operation of Comexi’s innovative offset printing technology at high speed, working with QuadTech’s SpectralCam system, solutions for gapless designs, reduction of make-ready time and enhancing productivity.

One of the main highlights of the Open House was that attendees could see three Comexi CI8 presses working at the same time, each one of them, with different features and configurations. One Comexi CI8 press included two gravure in-line up – and down – stream units. A second offset press was equipped with integrated robotization, where the robot provides sleeve loading and unloading services to the press but also to an integrated cylinder service station. This second press also featured in-line reel slitting abilities. And a third offset printing press was working with QuadTech’s SpectralCam in-line photo spectrometer combined with closed loop color control.

The attendees could monitor closely the two demonstrations featuring different print jobs, checking first-hand how the Comexi CI8 offers very short time-to-market due to its agile prepress system and a wide range of added values, and also had the opportunity to go in deep into Comexi’s offset printing quality, including a new temperature and humidity control system. 

Two of Comexi’s partners, Sun Chemical and QuadTech, contributed to the Open House. One of the speakers was Dr. Michael Hirthammer, managing director and VP Printing Inks Technology at Sun Chemical. He informed the audience about food packaging requirements and presented the latest developments in electron beam curable offset and flexo inks for flexible packaging.
