Large Flexo Stack printing, and ideal for market niches that require special formats and print widths.
Stability, accuracy, and repeatability are the main features of print output, and a great ease of use, even in large models thanks to automatic sleeve changing, sleeve lifting and handling systems, and integrated solutions for handling large components.
A Flexo printer for the flat and tubular film market and the paper industry, Concept is designed to print at a high quality level up to 3,200 mm span, and with print pitches up to 1,500 mm.
Stability and accuracy ensure high print quality even in large patterns up to 350 meters/minute.
Concept is designed with high flexibility of functions, from flat printing to recto/verso, protective lacquering or selective in-register coating for large-scale uses in the packaging and paper industry.
Available in water-based, solvent or UV+LED inks depending on the relevant product sectors.
The drying system is designed according to the most convenient energy sources available: gas, electric, thermal fluid or steam, and UV LED .
Energy saving is achieved through maximum optimization of heat sources and the automatic recirculation system taken to its maximum development by Expert.
Zer0WasteTM by Expert: fully automatic waste-free job setup to achieve immediate print pressures and registration with total elimination of waste at every job start .
Automatic calibration to the characteristics of the sleeve/cliché/biadhesive system for correct colour groups positioning.
Interactive system to progressively optimize parameters over time through an AI-based program.
Drastically reduce the start-up time of each job and the waste of time, materials and chemicals to zero.
Very high repeatability in recurrent work.
The use of Zer0WasteTMtechnology in conjunction with the Zer0WasteTM plate mounting through the use of computer systems programmed on AI parameters allows for waste-free job changeover.
The A-C System module allows inking of the circuit with a minimum amount of ink and enables effective cleaning of the entire circuit during the colour change phase.
The cleaning system is fully automatic and uses minimal detergents or solvents and total recovery of unused ink.
The washing system also allows cleaning of the viscometer circuit and is set by the operator station, which can be customized according to its working conditions and the chemicals used.
The system is structured in independent modules and allows for quick and easy inspection: each individual module can be detached for the purpose of dedicated periodic maintenance.
The washing program can be executed on all inking circuits simultaneously.
The inking circuit is sized to use the minimum amount of ink at the beginning of the job, avoid waste at colour change, and promote maximum print quality.
Perfectly functional for water-based, solvent-based or UV inks, the circuit cleans completely and to its full length with each wash cycle.
The newly designed doctor blades chamber keeps the ink in constant and regular flow, promotes wettability of the anilox, and allows emptying of residual ink at the end of use.
The doctor blade body is a brand new design and is made of high-stiffness aluminum, treated with Teflon anodization in order to facilitate cleaning, making it the ideal support for extremely long life of doctor blades.
Characteristics of doctor blades body:
Asymmetrically angled and calibrated blades.
Minimum pressure on the surface of the anilox.
Geometric position control to maintain correct position of doctor blades by Soft Touch Angle system.
Doctro blades consumption sensor and automatic alert to operator for replacement of doctor blades.
Lightweight and ergonomic doctor blades chambers for smooth handling.
Impossibility of accidental opening of doctor blades while printing.
Control circuit and maintenance of ink viscosity is controlled by PLC with injection of viscosity fluid;
The measurement takes place at customizable predetermined time intervals and allows selection of the preferred viscosimetry fluid.
Viscosity is measured by a simplified system that is extremely reliable and accurate, self-cleaning by normal flushing of the inking circuit and extremely easy to maintain.
Expert ensures maximum reliability by always researching new technologies to improve machine performance and ensure high quality standards.
Replacing the printing sleeve is quick and easy without the use of tools by unlocking and rotating the front support of the printing mandrel.
