Rotogravure or Flexography Printing?

 

Rotogravure


Picking sides in this case won’t be easy and straightforward!!!

Both Flexographic and Rotogravure printing technologies are well established in their own stature and have their fair shares of advantages and disadvantages.

Let’s try and understand the principle of Rotogravure and Flexographic Printing Technology!

Gravure printing is a type of intaglio printing process; i.e., it involves engraving the image onto an image carrier. In rotogravure printing the image is acid-etched on the surface of a metal cylinder—one cylinder for each color—in a pattern of cells. The cells are recessed into the cylinder, unlike relief printing or letterpress where the printing image is raised, or like offset printing, in which the image is level with the plate. The cylinder is etched with cells of different depths. These cells hold the ink that is transferred to the substrate. The dimensions of the cells must be precise because the deeper cells produce more intensive color than shallow cells.
