Three Colour Flexographic Printing Machine
Product Content & Technical Q&A — Rentech Machine Private Limited
The Rentech Three Colour Flexographic Printing Machine is an industrial roll-to-roll flexographic printing system designed for printing graphics, text, logos, product information and repeat patterns on flexible packaging substrates such as PP woven fabric, HDPE woven fabric, BOPP laminated material, Kraft paper, non-woven and other compatible substrates.
The machine is designed around synchronized unwinding, web feeding, printing, drying and rewinding, with each printing unit transferring ink through an anilox-based flexographic printing system.

Technical Q&A
Q1. What is a Three Colour Printing Machine?
A Three Colour Printing Machine is a flexographic printing machine with three independent printing stations. Each station applies one colour to the substrate.
By combining three printing colours, the machine can produce multi-colour designs, text, logos, graphics and packaging information.
Q2. What printing process does the machine use?
The machine uses flexographic printing technology.
The basic ink-transfer path is:
Ink → Anilox Roll → Printing Plate → Substrate
The anilox roll meters a controlled quantity of ink, which is transferred to the printing plate. The plate then transfers the image onto the moving substrate.
Q3. What materials can be printed?
Depending on the selected machine configuration, the machine can be designed for:
- PP woven fabric
- HDPE woven fabric
- BOPP laminated woven material
- Kraft paper
- Paper
- Non-woven material
- Jute-compatible substrates
- Other flexible packaging substrates
The exact substrate range depends on material thickness, surface treatment, ink system, web tension and machine configuration.
Q4. How many colours can be printed?
The standard configuration contains three printing units, allowing three-colour printing in a single continuous pass.
For example:
Printing Unit 1 → Colour 1
Printing Unit 2 → Colour 2
Printing Unit 3 → Colour 3
The machine can also be configured according to specific customer requirements.
Q5. What is the function of the anilox roll?
The anilox roll controls and transfers a measured quantity of ink to the printing plate.
Important anilox parameters include:
- Line screen
- Cell volume
- Cell geometry
- Roll diameter
- Surface condition
Correct anilox selection is essential for achieving consistent ink density and print quality.
