Opaque ink simulation on metallic substrates

Printing on metallic substrates unlocks a wide range of creative design possibilities, but also introduces specific challenges, particularly when proofing artwork. Achieving metallic effects typically involves using inks with varying levels of opacity, as commonly seen in beverage can production. Accurately simulating these effects in advance can be complex and time-consuming.

To produce highly realistic results while keeping effort and costs under control, GMG substrate proofing offers an effective solution.

By combining the advanced proofing and profiling capabilities of GMG ColorProof and GMG OpenColor, the visual impact of ink opacity is simulated through the application of a white undercoat. In this process, higher opacity levels in the final print are represented by increased amounts of white ink in the proof. Opacity can be defined individually for each color, allowing for precise and predictable results.

For proofing on metallic substrates, proof printers equipped with white ink can be used, such as the Epson SureColor SC-S80600 or Epson SureColor SC-S9100. For a complete overview of compatible devices, media, and print modes, please refer to our documentation on Supported proof printers, proof media, and print modes.
