Rotogravure printing: error free gravure prepress - Esko

Gravure prepress without errors

What is gravure?

Gravure is a printing technique in which an image is applied to a substrate using a metal cylinder. Contrary to flexographic or offset printing, gravure uses an engraved surface for the desired image. The image is etched into the metal cylinder.

During printing, this image carrier is immersed in fluid ink. As the image carrier rotates, ink fills the tiny cells and covers the surface of the cylinder. The surface of the cylinder is wiped, leaving the non-image area clean while the ink remains in the recessed cells.

Challenges in gravure

Just like most printing processes, printing gravure comes with its own set of challenges. Contact a gravure prepress specialist.

  • Consistent high quality printing. Long print runs have to deliver highly consistent results from beginning to end. Yet, there’s a very short time-to-market.
  • Dgravure trappingedicated prepress. To meet the rotogravure requirements, often entire designs have to be rebuild from scratch. To make this process as painless as possible, gravure prepress professionals need tools for align, clean-up, correct, separate, trap and convert their files.
  • Cost effective printing. The cost of a rotogravure cylinder is high. One of the ways to print cost effective and to reduce press-setup times is to make sure a series of jobs (variants) share the same cylinders. Dedicated tools can help you identify common content across product ranges and remove redundant cylinders.
