Black Ink Tone Comparison Between Conventional Inks and 2008 new genuine Canon dye inks
Test samples with solid black were created.The colors were measured and plotted on a coordinate system with a* and b* as axes. The point closer to the coordinate axes 0 produces more neutral black.
 
The wider the color gamut is, the more colors that can be reproduced. With the combination of 2008 new genuine Canon dye inks, FINE print head and new dye ink and "Photo Paper Plus Glossy II PP-201", "Photo Paper Pro II PR-201" and "Photo Paper Pro Platinum PT-101" greatly reproduction is experienced with certain colors, especially in red areas (yellow ~ red ~ magenta) compared to the combination of previous dye inks, FINE print head and photo papers. Richer and brighter color is now provided.
 
Importance of Black Ink
Black ink is a determining factor in the density and contrast of the image as a whole. Depending on the coloration properties of the black ink, an image can provide a dynamic three-dimensional feel, or end up giving a flat impression. The dye's color tone is also extremely important to image quality. Creating a perfect, colorless black with inks is extremely difficult. At the same time, however, black that does not take on any color sharpens the photo and brings out its beauty.

Making Photo Black Ink More Neutral

Canon has been working on neutralizing the photo black ink and this time succeeded in bringing the tone of the photo black ink closer to neutral, thus improving its visual blackness by combining a variety of dyes.

Note for preserving and displaying photos

The image permanence estimates presented in this technology guide may vary depending on display/storage conditions. The expressed numbers of years estimates are the result of simulated, accelerated tests conducted by Canon Inc. and do not represent a product guarantee.

Light, environmental gases, high temperature and humidity can accelerate color fading. When displaying your photographs, avoid high intensity lighting and use glass-filtered frames. Photos stored in the dark, using archival quality albums or storage materials, will tend to last longer than photos that are exposed to light. Avoid high temperatures and high humidity to promote the image permanence of your photos.
