About Us


What we do?

UFlex Cylinder Business has an advanced manufacturing unit for the production of Rotogravure Printing Cylinders, Flexo Plates & Flexo Printing Sleeves that carry out the intaglio printing process, which involves engraving & transfer of the image onto an image carrier. The image is engraved on Cylinders/ Flexo plates. To manufacture these cylinders, we carry out the whole process right from the steel base, copper plating, surface finishing, digital engraving, chrome plating and to final proof print.

2) Pre-press:

The Digital Pre-press Department at UFlex uses a specialized packaging and planning software ART PRO & Pac Zed to meet all kinds of Gravure & Flexo printing requirements. The software is the last word in techniques like colour separation, trapping, barcode generation and Pantone. For optimum halftone results, the highly experienced and internationally trained professionals at the manufacturing facility spin their magic on colour calibrated monitors. Besides this, we have exclusive software specially deployed for a fine making-of wallpapers, wood grain and texture design cylinders. Furthermore, to achieve vibrant and rich colours, technology, Hexa-chrome is put in use.

The digital file finally gets ready to be engraved on the printing cylinder. At UFlex, the confidentiality of the job is maintained. We prioritize to safeguard the interests of our esteemed customers with advanced ERP solutions.

II) Plating line from trusted suppliers

Dynamically balanced base shells with accurate thickness and hardness are passed through high precision imported grinders to make sure engraving meets international standards. The base shells then undergo a sophisticated multistage galvanic process on the state-of-the-art fully automated and environment-friendly galvanic line from MDC Daetwyler, Switzerland. At this stage, they are de-creased to get rid of dust, oil, dirt or any other foreign particles before undergoing uniform electroplating of nickel and copper. In chrome plating, we can get hardness above 1100 vikers & microcracks 400/cm (Min).

V) Cylinder Proofing

All the manufactured gravure printing cylinders are reviewed to cross-check the standard process parameters and also to validate output synchronization amongst Pre-press, Engraving machine and Printing machine.
Accucheck proof reader:
The unique proofreading process is conducted to ensure efficiency. The actual proof on the substrate is scanned and superimposed on the soft file of the approved design. This customized software can easily detect any deviation.

VI) Quality Checks

QC at each and every stage of the process:-

  • Proofreading, shade matching as per customer’s requirement; checking for Delta E and LAB values of colors, Barcode verification & reporting.
  • Chemical analysis of plating baths on a daily basis.
  • Standardized engraving parameters & cylinder quality analysis.

C) Flexo Printing Sleeves:

The fibreglass sleeves are covered with elastomer or polymer using the sleeves technology, then the sleeves are directly engraved by using CO2 or YAG lasers. In the final stage, the finished sleeves are then slid onto the air mandrels of the flexography printing machine. Moreover, a Lead Laser Sleeve making facility has been introduced to add all the more high precision to flexo sleeves production at UFlex Jammu plant.

Operational Excellence

With time and innovations, we have diversified our manufacturing facilities by adding Flexo ‘Xlarge’ Laser of high definition image up to 5080 DPI with flexo proofer. Schepers Laser has also been added to the kitty. These developments have brought UFlex ahead of the competitive curve in the area of application for Packaging, Corrugated Printing, Specialized Coating, Embossing, Metallic Dies, Decorative Laminates, Security Features etc.

Digital processing during our rotogravure production enables us to produce a perfect register – a potent combination of electronically engraved, chemically etched embossing cylinders.

The recent installation of Robotic Laser Engraving Line from M/s Think Lab, Japan, has enabled UFlex to produce more than 80 Cylinders per day

To make sure that engraving meets international standards, dynamically balanced base shells with accurate thickness and hardness are passed through high precision imported grinders.

We adopt Stringent Quality Control at each stage of production to ensure world class cylinders. Few of our practices include:

  • Period calibration of scanner-monitor-prepress digital-cylinder proof
  • Checking and improving the H/T images on the colour calibrated monitors to the minutest of detail
  • Dynamic balancing of each cylinder at 500 RPM
  • Blueprint for cone and bore's accuracy
  • Proof reading and comparison with the original artwork before engraving cylinders
  • Inkjet proofing of complete cylinder layout through the circumference and width
  • Daily analysis of electroplating baths for Nickel, Copper and Chrome.
  • Accurately checking copper hardness of each cylinder.
  • Accurately checking chrome hardness of each cylinder.
  • Diameter of each cylinder from one end to the other is gauged.
  • Roughness of each cylinder is ascertained.
  • Cell geometry (Cell width/ Cell wall/ Depth) for each cylinder is checked to ensure correct reproducibility and consistency.
  • Meticulous checking and matching of each cylinder proof with the master sample/ artwork-prior to dispatch. Appropriate packing of cylinders is carried out to avoid any damage while in transit.
