When it comes to packaging and label printing, two popular printing methods stand out: flexographic printing (flexo) and rotogravure printing. Both techniques are widely used for printing on various materials like plastic, paper, and foil. However, they are quite different in how they work, the quality they offer, and the type of ink they use—especially rotogravure ink, which plays a big role in the rotogravure process.
In this blog, we’ll explore the main differences between flexo and rotogravure printing, the advantages of each, and how to choose the right one based on your needs. Whether you’re a manufacturer, designer, or business owner looking to print high-quality packaging, this guide is for you.
Understanding the Basics of Flexographic Printing
Flexographic printing, often called flexo, is a modern version of letterpress printing. It uses flexible relief plates made from rubber or photopolymer, which are wrapped around rotating cylinders. These plates are inked and pressed onto the substrate (material to be printed), transferring the image.
Key Features of Flexo Printing:
- Ideal for large-volume packaging jobs
- Can print on various materials: plastic, foil, paper, film, and more
- Uses quick-drying inks such as water-based or UV inks
- Known for faster production speeds
Flexo is popular in the food packaging industry due to its ability to print consistently on flexible materials.
What is Rotogravure Printing and How Does It Work?
Rotogravure printing, also called gravure printing, is a fast printing method used for large jobs. It uses metal cylinders with tiny engraved cells that hold ink. When the cylinder rolls over the material (like plastic or paper), it presses the ink onto it in a clear and detailed way.
This printing method is best known for creating bright colors, sharp images, and smooth color blends, which is why it’s often used for high-quality and premium packaging.
Core Features of Rotogravure:
- Exceptional print quality, especially for images and fine details
- Perfect for long-run printing of the same design
- Uses specialized rotogravure inks that offer excellent adhesion and sharpness
- Suitable for materials like polyester, BOPP, PVC, and foil
Flexo vs Rotogravure: What’s the Main Difference?
The key differences between these two printing methods can be broken down into several important categories:
1. Printing Plates vs Engraved Cylinders
- Flexo: Uses soft, flexible printing plates mounted on cylinders.
- Rotogravure: Uses metal cylinders with engraved designs.
This difference affects both the cost and the quality of printing. Rotogravure offers better detail due to its precision engraving.
2. Ink Type and Performance
- Flexo: Commonly uses water-based or UV-curable inks.
- Rotogravure: Uses solvent-based rotogravure inks, known for deep color penetration and excellent adhesion on films and foils.
Rotogravure ink plays a critical role in achieving the high-definition quality of gravure prints.
3. Print Quality
- Flexo: Good for general packaging needs but may struggle with complex images or fine details.
- Rotogravure: Known for photographic-quality results, especially on flexible packaging.
4. Setup Time and Cost
- Flexo: Faster and more cost-effective to set up for short runs.
- Rotogravure: Higher initial cost due to cylinder engraving, but cheaper per unit for long print runs.
5. Production Speed
Both processes are high-speed, but Flexo generally offers faster turnaround for smaller orders.
When Should You Choose Gravure Printing?
If your packaging requires rich colors, fine details, and consistency over long runs, rotogravure is the way to go. It’s especially popular in industries like:
- Cosmetics
- High-end food packaging
- Pharmaceuticals
- Luxury retail
Its ability to produce vibrant, repeatable results makes it ideal for companies with large-volume printing needs and high visual standards.
The Role of Rotogravure Ink in High-Quality Printing
Rotogravure ink is specially formulated for the gravure printing process. These inks are typically solvent-based, which means they dry quickly and bond strongly to non-porous surfaces like plastic and foil.
