Gravure printing stands as a high-quality method, conveying ink from differently sized and deep grooves onto the printing surface to achieve a continuous tone effect reminiscent of photographs.
During gravure printing, the resulting effect hinges on the ink transfer from distinct-sized and deep grooves etched into a copper-covered steel cylinder. Up to 22,500 grooves can be found per square inch of the cylinder, varying in size and depth to create differing image densities.
Larger or deeper grooves transfer more ink to the surface, yielding larger and/or darker areas. Untouched areas of the cylinder become non-image regions.
Originally, grooves on gravure cylinders had equal surface areas but varying depths. Today, grooves on cylinders are crafted with differing surface areas and depths or identical depths but different areas. This flexibility suits the production of high-quality work across diverse applications. Grooves of varying areas but equal depths often serve gravure cylinders for packaging. Cylinders with grooves varying in both area and depth are reserved for top-quality printing.
Gravure's output boasts exceptional image quality due to thousands of ink grooves seemingly merging into a continuous tone image. However, a limitation lies in the quality of small fonts, which, although good, may not be as sharp as fonts printed using techniques like offset lithography. This stems from fonts being created with individual grooves, mirroring the rest of the image, rather than as a continuous solid shape.
Gravure printing is an intricate technique, often performed through rotary web processes. Applying ink to minuscule grooves on cylinders and transferring it onto printing material produces vibrant, continuous tone printing effects. This method enjoys widespread use in meeting demands for high-quality image reproduction, spanning magazines, packaging, wallpaper, and other premium printing applications.
Despite slight constraints on small fonts, the unique appeal of gravure printing lies in its ability to deliver intricate, refined image effects for a wide array of printing applications, cementing its importance in the printing industry.
