Main benefits for you
Register and printing unit pressure setpoint
Faster setpoints, less shrinkage, more benefits
The job changeovers in flexo presses generate waste in web and inks that have a significant impact in the profit and loss account. The current trend to reduce runs implies more changeovers, an increase in the total waste generated during the setpoints and a loss in machine efficiency.
At Comexi we have launched a set of solutions that adapt to the difference scenarios facing our clients. The CINGULAR MODULES offer automatic and semi-automatic features, with or without a mark, adapted to the specific requirements of our industry.
Automatic printer unit pressures and register system.
Use of trademark.
Average waste generated throughout the 100 m process on one side and according to the repeat.
Inspection system with camera.
Automatic printing unit pressure setpoint system.
Waste generated in the process between 20 and 160 m (with an average of 90 m) according to the repeat.
Suitable module for adding to the CReg semi-automatic register module without marks.
Semi-automatic register setpoint system for third party manufacturers.
Without specific marks.
Inspection system with camera.
The CINGULARPress2 module can be added to improve the automation.
Automatic system for printing unit pressures and register without dedicated marks.

Register setpoint using the 100% print view and comparing it with the digital file (PDF) used to create the plates.
Average waste generated throughout the 200 m process.
100% inspection system with state-of-the-art linear camera.
Excellence with the most efficient cleaning system
The Comexi SelfCleaning is an automatic system that manages the ink supply to the print, and cleans the ink chamber, the anilox, ink tanks and connection hoses in the circuit.
The system adapts to water-based inks and solvent-based inks.
Its high level of automation makes it possible to program different cycles (from light to intensive) to adapt solvent and time consumption to your needs. These advantages combined with the easy use thanks to the simple interface, complete a system designed according to the highest standards of efficiency.
MAIN BENEFITS FOR YOU
INTEGRATION AND ERGONOMICS
The SelfCleaning is built into the actual machine frame. Its ergonomic arrangement provides for easy operator access and facilitates the maintenance tasks for all elements.
The system includes tanks for the solvent that connect to solvent recovery equipment, achieving safe and fully automatic operation.
CONTROL OVER THE INK
It includes built-in online viscometers to automatically regulate the viscosity in the values set up as optimum for printing. An upgrade of the standard version also includes a temperature regulating system in order to maintain the ink working temperature.
The new electronic control allows continuous control over the working and performance of the various valves, saving large amounts of ink and reducing costs.
MACHINE SCREEN CONTROLS
Visualising the system parameters via the PLC allows you to control the process from start to finish. The impulse and time screens provide preventive maintenance, minimising the machine stops as well as achieving the system's best setpoint.
BETTER PERFORMANCE AND LESS MAINTENANCE
The pneumatic pumps controlled by the PLC manage the ink induction and suction, at the same time as adapting the frequency to the print needs prolongs the life of the membranes.
The combination of bearing supports reinforced with larger diameter and the hydraulic axes carbon fibbers offer the most robustness possible against impacts. At the same time, allows high print quality at high speed.
Easy access to the printing units
The press has 8 decks adapted for a front print. Its design adapts to the easy access requirements for maintenance and daily operation thanks to the FLEXOEfficiency concept.
High performance doctor blades
The doctor blade is assembled in a closed swinging chamber mounted on linear guides, with automatic horizontal movement by means of low friction, pneumatic pistons.
It is dismantled easily without having to disconnect the inking tubes, facilitating the cleaning and changeover tasks, with simple handling thanks to its extraordinary 12 kg weight.
Thanks to the patented ComexiMAGNETBlade technology, a tool-free magnetic changeover system, we can obtain a fast and safe blade and seal changeover.
Fast sleeve changeover
The plate cylinder and anilox sleeve changeover takes a couple of minutes. The covers are opened manually, in a quick, simple way.
Drying: Power and accessibility
The drying equipment is made up of two fully independent circuits which, via two blowers, blow hot air at high speed, evaporating the solvent or water contained in the ink.
The first circuit is used to dry between printing units. The screen can be removed freely from the machine by disconnecting the tubes from the inside, and the housing includes an inspection door, so maintenance is comfortable and easy. Both concepts are patented by Comexi.
The second corresponds to the drying tunnel, which is 5 m long. It is made up of sixteen drying boxes each one with a blower nozzle, with tubes arranged to optimise heat loss. The screens can be dismantled easily and do not need tools for cleaning. The tunnel includes an specific opening for maintenance and cleaning.
The Comexi F2 MP represents excellence in ergonomics and usability. It is fitted with a top diaphanous platform which provides access to all the elements requiring maintenance, highlighting the access to the set of rollers at the tunnel exit.
The F2 ML stands out for its accessibility. You can reach easily to all points of maintenance and cleaning without having to use ladders or work from high altitude. Drying screens can be folded to clean them quickly and you do not need any type of tool.
These are just some of the details that enhance this machine as the best solution in terms of maintenance for its easy handling, access to changing filters, lubrication points or decentralized electronic panels.
Electronics and perfectly adapted interfaces
The press is designed so that most of the functions can be controlled from the control console. In parallel our COMPACT concept, based on the SIMOTION platform and in decentralising the electronics, provides for high electronic integration, thereby eliminating electronic equipment containers and facilitating maintenance tasks.
At Comexi we apply the DDDrive concept for driving the shafts via AC motors without any kind of mechanical transmission, controlled by absolute encoders coupled directly to the shafts. All improving the register and, consequently, the quality of the print.
You will obtain production data for subsequent analysis such as the amount of meters printed, the amount of meters lost, the job duration time, stop times, print times, average real speed, etc.
With the operator attributing the cause of the stop, statistics are obtained on the various causes of stops and the time assigned to each one. All the data can be stored in the computer memory and/or in external data storage devices.
Work files can be created to increase the efficiency in the job changeovers, and these files can be recovered subsequently.
The ENERGYSavvy concept, applied to a set of electrical and electronic control technologies, saves large amounts of energy and drastically reduces CO2 emissions.
