Difference between roto and flexo printing
2023-06-10
Roto printing, also known as rotogravure printing, and flexo printing, also known as flexographic printing, are two popular methods used in the printing industry. While they share similarities in terms of printing on various substrates, there are several key differences between the two processes.
Here are some of the main distinctions:
Printing Plate Technology:
Roto Printing: In rotogravure printing, the image to be printed is engraved or etched onto a cylinder using a laser or chemical process. The engraved cells hold the ink, which is transferred onto the substrate during printing.Flexo Printing: Flexographic printing utilizes flexible printing plates made of rubber or photopolymer materials. These plates are mounted onto a cylinder or sleeve and transfer the ink directly to the substrate.
Image Quality and Resolution:
Roto Printing: Rotogravure printing is known for its high image quality and excellent color reproduction. It can achieve finer details and smoother tones due to the use of engraved cylinders.Flexo Printing: Flexographic printing has made significant advancements in recent years, offering improved image quality. However, it may have slightly less resolution and finer detail capabilities compared to rotogravure printing.
Substrate Compatibility:
Roto Printing: Rotogravure printing can work effectively on a wide range of substrates, including paper, plastic films, foils, and laminates.Flexo Printing: Flexographic printing is highly versatile and suitable for printing on various flexible materials such as paper, cardboard, plastic films, labels, and corrugated board.
Cost and Setup Time:
Roto Printing: Rotogravure printing often requires substantial setup time and costs due to the production of engraved cylinders. It is more suitable for large print runs.Flexo Printing: Flexographic printing offers faster setup times and lower initial costs compared to rotogravure. It is well-suited for shorter print runs and flexible packaging applications.
Printing Speed:
Roto Printing: Rotogravure printing can achieve high-speed production rates, making it suitable for large-volume printing jobs.Flexo Printing: Flexographic printing can also operate at high speeds, although it may be relatively slower compared to rotogravure printing.
Both rotogravure and flexographic printing have their own advantages and applications. The choice between the two depends on factors such as print quality requirements, substrate characteristics, print volume, and budget considerations.
