Opacity by the numbers: Discover the best practices for superior opaque white printing — and reducing ink consumption.
Apex International & Coveris White Ink Project
Project CPQ delivers the proof: GTT engravings deliver best-quality opaque white ink results – and use less ink.
The design and image fidelity of packaging plays a key role in the decisions we all make as consumers, which in turn drives demand. Within the print process, opaque white ink is the very foundation for graphic imaging on a variety of substrates. It is the essential backdrop upon which brands express their carefully-crafted imagery.
Therefore, critical success factors for proof-matched flexo printing include opaque white ink layering of sufficient opacity and quality.
Coveris approached Apex to support a project specifically focusing on the print process and to fine-tune the performance of the white ink lay-down after experiencing issues with printing opaque whites. They noticed that applying excessive white ink had numerous implications on the press performance such as slower press speeds, higher drying temperature, heavier packaging, excessive ink consumption — in addition to the carbon footprint of the additional ink and transport.

Uncover the science of opaque white printing...
Watch this entertaining animation to learn the physics of opaque white ink printing.
Sub-standard opacity — caused by mottling, pin-holing, or poor ink homogeneity — can badly alter your printed color palette results. Peek into the science behind GTT’s revolutionary anilox geometry that reliably delivers the best opacity — and can even require less ink and faster clean-up.
