Engraving printing and flexographic printing are two common printing technologies that are widely used in the printing industry. Although they can both be used to produce high-quality print, there are some important differences in how they work and where they are suitable.

First, engraving printing is a letterpress printing technique that uses grooves or pits to transfer ink. This method usually uses a rotating printing roller to transfer the ink to the printing medium, such as paper or plastic. Engraving printing is suitable for high-volume production, especially for printed products that require high resolution and fine images, such as magazines, books and packaging.

In contrast, flexography is a gravure printing technique that uses a flexible printing plate to transfer ink. This method is suitable for curved and irregular surfaces of printed media such as plastic bags, cartons and labels. Flexographic printing is often used for low-volume production because it allows quick plate changes and has low manufacturing costs.

Another difference is in print quality. Since engraving printing uses a printing roller with higher pressure and deeper grooves, it can produce higher print quality and finer image details. Flexographic printing, while not as high quality as engraving printing, can still provide adequate printing for some applications.

In addition, there are differences between engraving printing and flexographic printing in terms of printing medium and ink selection. Engraving printing can be used on various papers and plastics, while flexographic printing is more suitable for plastic and film materials. Likewise, engraving printing uses thicker inks, while flexographic printing uses thinner inks.

To sum up, engraving printing and flexographic printing are two different printing technologies, and they have obvious differences in terms of working principle, scope of application, printing quality and ink selection. Understanding these differences can help us choose the printing technology that best suits our needs and achieves the best printing results.
