How it works

The CMYN gamut is not enough for making most of the special colors.
The addition of orange, green and blue colors expands the range, making it possible to create colors that are otherwise not reproducible except through the use of special colors.
If we report the display of reproducible colors in four-color process (see image above), we notice all the color space not present within the triangle that highlights the special colors that can only be reproduced with the seven-color process.

For the calculation of the colors, a dedicated software use special algorithms and ICC profiles.
It deals with the conversion of colors both within the images and for the reproduction of spot colors.
The operator can manage, based on his experience, the more direct ∆E compatibility.
You can opt for a wide range of alternatives aimed at improving print stability and optimizing color fidelity as well as simplifying the register.
The fusions between the colors are converted and managed for the optimization of the colors and the elimination of corner conflicts.

The use of the heptachromy process, other than the undoubted advantage of obtaining spot colors without long mixing times of the inks, allows to improve the color rendering within the images.
The expansion of the color space, for example, allows you to revive a lawn, reinforce the blue tones by preventing the classic purple change on one detail without interfering with others, for example the sky.
Inhibit the orange in skin tones and make numerous other changes giving more depth to the images.
Many colors that "fade" in four-color process are revived by the expansion of the gamut.
