For the 12 LUCIA pigment inks, in addition to CMY ink colors, Canon developed special complementary RGB colors (complementary color*5 relationship) and two shades of gray,*6 realizing an expanded range which enables greater overall balance. With LUCIA, vivid colors can now be achieved on a variety of media types, including glossy paper.
The new LUCIA EX pigment ink system increased the color reproduction range by up to 20% by using more vivid pigments for all 12 colors and through the use of pigments with a variety of particle diameters. Furthermore, we have successfully produced a dark black using an ink design for raising the grade of black in order to meet the demand for high image quality from professional photographers and creators. By also improving ink materials, we successfully reduced bronzing*7and improved rubfastness.*8
- *4 Dye and pigment
Ink is made up of pigment, solvent, additives, and water. Pigment is dissolved at the molecular level in dye ink but, in pigment ink, is only dispersed without being dissolved. Each ink type has its own strengths, with dye ink offering subtle color expression well suited for use in photo prints and pigment ink delivering superior light fastness.
- *5 Complementary colors Pairs of colors located on opposing sides of the color circle. When adjacent to one another, complementary colors are emphasized and seem more saturated, such as magenta-colored flowers against green leaves.
- *6 Dark and light gray ink. Dark and light gray ink reduce the graininess of gradation in dark areas of an image. Because gray printing uses little colored ink, it reduces the impact of light sources on printouts.
- *7 Bronzing. A phenomenon in which colors seem to differ from the original color or have a metallic shine due to diffused reflection of illumination on the print surface.
- *8 Rubfastness. Ink's rubfastness refers to preventing the surface from peeling or being scratched when a printed surface is rubbed.
