MLS Rotogravure Printing Machine

High-Performance Multi-Colour Printing for Flexible Packaging

Our MLS Rotogravure Printing Machine is engineered for high-quality multi-colour printing on flexible packaging materials. The machine combines individual printing stations with controlled web handling, accurate colour registration and efficient drying to maintain consistent print quality throughout continuous production.

Designed for substrates such as BOPP, PET, PE, CPP, PVC, laminated films, aluminium foil and suitable paper, the machine can handle a broad range of flexible packaging jobs. Its printing, drying, tension-control and rewinding sections operate in coordination to maintain stable web movement from the first printing station to the finished roll.

The MLS configuration is suitable for converters producing printed packaging for food products, pouches, confectionery, personal-care products, household goods and other consumer packaging applications.

Engineered for Consistent Multi-Colour Printing

Colour registration control is very important in multi-colour gravure printing. Any changes in the web tension, cylinder positioning and drying will influence the registration and the end result print appearance. The MLS Rotogravure Printing Machine is engineered to provide controlled movement of the web as it passes through each of the colour stations.

In each of the printing stations, there is a colour application using the gravure cylinder, ink system and the doctor blade. Controlled registration and web tension systems will ensure colour registration, while the drying system between printing stations gets the web ready for the next colour.

This process enables graphic prints with detailed designs and reliable printing for longer periods.

Designed for Flexible Film & Packaging Substrates

The MLS Rotogravure Printing Machine can process different flexible packaging materials, including BOPP, PET/polyester, PE, CPP, PVC, laminated films, aluminium foil and paper-based substrates.

Because every substrate responds differently to tension and heat, the machine uses controlled unwinding, web tension, drying and rewinding to maintain stable material movement. Machine settings can be adjusted according to the substrate thickness, printing requirement and production conditions.

The finished printed roll can subsequently be used for lamination, slitting, pouch making, bag making and other packaging-conversion processes.

Why MLS Configuration is Suitable for Flexible Packaging Printing

In the MLS system, there is a planned layout of many print stations on the web line. Every station does some sort of printing in a certain color, making it possible for the desired design to be constructed gradually while passing through the equipment.

The individual print and dry stations give much more control over each process step. It is especially true for complex package designs with several colors, graphics, text and patterns.

Controlled tension, registration and drying also help to prevent typical problems like color misregistration, web shifting and insufficient inter-color drying.

Key Features

Controlled Hot-Air Drying: Provides controlled drying conditions according to printing speed, ink and substrate requirements.
Individual Inter-Station Drying: Each colour can be dried before the substrate enters the following printing station.
Continuous Ink Circulation: Maintains a consistent supply of ink at individual printing stations during continuous operation.
Precision Doctor Blade System: Removes excess ink from the gravure cylinder surface, leaving ink within the engraved cells for controlled transfer.
Automatic Web Tension Control: Maintains controlled substrate tension from unwinding through printing and rewinding.
Accurate Colour Registration: Automatic registration controls help maintain alignment between individual colours throughout production.
Multi-Station Printing Configuration: Multiple printing stations enable successive colour application for detailed flexible-packaging designs.

Frequently Asked Questions

What processes can be carried out after printing?

After printing and rewinding, the roll can move to processes such as lamination, slitting, pouch making or bag making, depending on the final packaging structure.

Is the MLS machine suitable for food packaging?

Yes. It can print compatible flexible-film substrates used to manufacture packaging for snacks, confectionery, spices, biscuits, dry foods and similar products.

Why is drying required between printing stations?

Drying helps remove the required solvent or moisture from one printed colour before the substrate enters the next station. Proper inter-colour drying helps prevent smudging and unwanted mixing between colours.

How does the machine maintain colour registration?

The machine uses automatic registration control together with controlled web tension and synchronized printing stations to maintain alignment between successive colours.

Can the MLS machine be used for multi-colour printing?

Yes. The machine can be configured with multiple printing stations, including 8, 10 and 12-colour configurations, according to the required application.

Which materials can be printed on an MLS Rotogravure Printing Machine?

Depending on machine configuration, suitable materials include BOPP, PET, PE, CPP, PVC, laminated films, aluminium foil and paper.

What is an MLS Rotogravure Printing Machine?

An MLS Rotogravure Printing Machine is a multi-station gravure printing system designed for continuous multi-colour printing of flexible packaging substrates. Individual printing and drying stations work together with web tension and registration controls to produce the finished printed roll.
