The engraved cylinder is then coated with ink and a doctor blade is used to scrape off the excess ink, leaving the ink only in the engraved areas. The substrate is then passed between the engraved cylinder and a pressure roller, which transfers the ink onto the substrate.

Rotogravure printing can be expensive due to the cost of the engraved cylinders and the equipment needed to produce them. Additionally, the process can be wasteful since a separate cylinder is required for each color used in the design. However, the high quality and speed of the printing process can justify the cost for some applications. The cost-effectiveness of rotogravure printing depends on the specific requirements of the job, the size of the print run, and the available printing technology alternatives.

The principle of rotogravure printing involves transferring ink from engraved cells on a metal cylinder onto a substrate. The process begins by engraving an image onto the surface of the cylinder using a chemical etching or electroplating process. The engraved cells on the cylinder correspond to the desired image or design. Ink is then applied to the cylinder and wiped off the surface, leaving ink only in the engraved cells. When the substrate, such as paper or plastic film, passes through the nip between the cylinder and a pressure roller, the ink is transferred from the engraved cells to the substrate. The pressure of the roller ensures good contact between the substrate and the cylinder, resulting in high-quality prints with sharp, crisp lines and vibrant colors. The process can be repeated with different cylinders and inks to produce multi-colored prints.

Rotogravure printing and flexo printing are two different types of printing processes that use different technologies to transfer ink onto a substrate. The main differences between the two are:

Some common problems that can occur in gravure printing include:

  1. Ink smearing or blotting: This can occur when the ink is applied too thickly or unevenly, or when the substrate is too absorbent. It can result in smudged or blurry prints.

  2. Poor color registration: This occurs when the colors in the design do not align correctly. It can be caused by a number of factors, such as cylinder misalignment, substrate shrinkage, or inconsistent ink coverage.

  3. Ink spitting or pinholing: This occurs when small air bubbles or voids in the ink film cause small gaps or imperfections in the print. It can be caused by a variety of factors, including ink viscosity, cylinder surface roughness, or ink drying too quickly.

  4. Ghosting or banding: This occurs when a faint, secondary image appears next to the main image. It can be caused by a number of factors, such as uneven ink transfer, cylinder damage, or substrate irregularities.

  5. Cylinder wear or damage: Over time, the engraved cells on the cylinder can wear down or become damaged, resulting in reduced print quality or inconsistent ink coverage.

These problems can be addressed through a combination of process adjustments, such as adjusting ink viscosity or cylinder pressure, and equipment maintenance, such as regular cylinder cleaning and replacement.

The cost of gravure printing can vary depending on several factors, such as the size of the print run, the number of colors used in the design, the complexity of the design, and the type of substrate being printed on. Generally speaking, gravure printing tends to be more cost-effective for larger print runs, as the initial setup costs (such as producing the engraved cylinders) can be spread out over a larger number of units.

As a rough estimate, the cost of gravure printing can range from a few cents to several dollars per unit, depending on the factors mentioned above. It’s important to obtain a quote from a printing company to get an accurate idea of the cost for a specific print job.
