The ideal solution for water-based printing

The Comexi F2 WB machine is the perfect solution for sustainable printing, in medium and long runs, using water-based inks without having to compromise the speed and/or quality. 

The press is available in widths of 1270 mm to 1470 mm, in 8 colours and with print repeats of up to 850 mm. 

With drying designed especially for water-based inks, the model allows you to obtain a greater printing quality at speeds of up to 500 m/min and to print on different substrates, in forward and reverse printing for lamination.

Cingular Modules

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.
  • Printing unit pressure setpoint using the 100% print view.
  • 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.




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.



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.



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.



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.


Ideal water-base drying
Ideal water-base drying

The group of technologies patented by Comexi under the FlexoEfficiency concept includes the drying system designed particularly for optimising the drying of water-based inks at high speed.

  • High flow rate drying equipment dedicated exclusively to drying white and the background of the first colour with dehumidified air.
  • Up to 50% greater between colours drying capacity and 30% in the final tunnel with respect to the equivalent F2 model for solvent-based inks.


Exclusive inking circuit

The model offers an exclusive inking and cleaning system for the printing units in stainless steel, designed for jobs with water-based inks.

Corona treatments

The surface treatments are extremely critical when printing with water-based inks. At Comexi, we have fitted the F2 WB with the best corona treater solution.

High performance doctor blades
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.

Easy working on the platform

The Comexi F2 WB represents excellence from the point of view of 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.

Easy maintenance

You will find several details that highlight this machine as the best solution in terms of maintenance: its easy handling and doctor blade access, filter change, greasing points, decentralised electronic panel, and others.

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.

Energy efficiency

The ENERGYSavvy concept, applied to a set of electrical and electronic control technologies, saves large amounts of energy and drastically reduces CO2 emissions.
