CVD Vantablack was an improvement over similar substances developed at the time. Vantablack absorbs up to 99.965% of visible light and can be created at 400 °C (752 °F). NASA had previously developed a similar substance that was grown at 750 °C (1,380 °F), which required materials to be more heat resistant than Vantablack. [24]
Rich black is often regarded as a color that is "blacker than black". While this is impossible from the point of view of color theory, the difference can often be seen in the printed piece. The difference is most apparent in backlit (also known as "translite") pieces, where rich black more thoroughly blocks the light from coming through.
Overprinting refers to the process of printing one colour on top of another in reprographics.This is closely linked to the reprographic technique of 'trapping'.Another use of overprinting is to create a rich black (often regarded as a colour that is "blacker than black") by printing black over another dark colour.
The sentence "Vantablack was an improvement over similar substances developed at the time." seems a bit odd, as no points of time have yet been mentioned at this point in the article. Maybe it should say something like "Vantablack is an improvement over similar substances developed before it"? JoaCHIP 10:39, 8 June 2019 (UTC)
[1] [2] Applications of super black are in specialist optical instruments for reducing unwanted reflections. The disadvantage of this material is its low optical thickness, as it is a surface treatment. As a result, infrared light of a wavelength longer than a few micrometers penetrates through the dark layer and has much higher reflectivity.

Shades of black, or off-black colors, are colors that differ only slightly from pure black.These colors have a low lightness.From a photometric point of view, a color which differs slightly from black always has low relative luminance.
Ann Thetis Blacker (13 December 1927 – 18 December 2006) was an English painter and singer. She was noted for her richly coloured pictures, especially using the batik wax-resist fabric dyeing process. [1] Blacker was born in Holmbury St Mary, Surrey, England. [2]
