SJH OVI ink copper to green color shift test: copper-gold and green alternate with viewing angle with rich luster - for cigarette packs, wine labels and card security.
A full written description of the demonstration, so the content is readable without playing the video.
This video demonstrates the copper-to-green colour shift of SJH OVI ink: copper-gold and green alternate with viewing angle with rich, saturated appearance - for cigarette packs, wine labels and cards.
The video shows the copper-gold hue from the front. Copper-gold (red-gold leaning) is one of the most common starting hues in the OVI family and is widely used in the brand colour areas of cigarette packs and wine labels, because it already carries a metallic, premium feel that gains further depth with an angle-dependent shift.
At an oblique angle the copper-gold switches to green. A single OVI system can be designed with several hue pairs (gold-to-green, gold-to-red, purple-to-gold and more); which pair to choose depends on the customer brand colour, substrate and visual design. Confirming with a physical proof at different angles is recommended.
The video shows the saturation of this effect. Copper-to-green is fairly sensitive to substrate and process: dark substrates enhance the contrast of the shift, while light or highly reflective substrates can weaken the visual impact. On applications with an existing base design, such as cigarette packs and wine labels, the position of the OVI area is normally planned together with the layout.
| Hue pair | Copper-to-green (the same system also offers gold-to-green, gold-to-red, purple-to-gold and others) |
|---|---|
| Substrate | Dark substrates enhance contrast; light or reflective substrates may weaken it |
| Layout | Plan the OVI area together with the packaging layout |
| Typical use | Cigarette packs, wine labels, cards and premium brand packaging security |
Choosing an OVI is not just choosing a colour - it is choosing the combination of hue pair, substrate and layout placement. The same copper-to-green ink printed on a dark versus a light substrate differs markedly in impact, and whether the OVI area sits on the brand logo or in a separate icon zone changes both security strength and design feel. These are best assessed at the proofing stage against the actual layout; we can supply comparison proofs on different substrates.
