Which type of ink does a wavelength of 1064 primarily attract?

The wavelength of 1064 nanometers is in the near-infrared spectrum. This specific wavelength is particularly effective at being absorbed by darker pigments and inks, making it most compatible with dark ink. The reason dark ink absorbs more of this wavelength is due to the higher concentrations of pigments that absorb light in that spectrum, which allows for more effective laser interaction and targeting.

In contrast, lighter inks tend to reflect more light rather than absorbing it, making them less effective when exposed to the 1064 nm wavelength. Colorful inks may have specific absorption characteristics based on their pigment composition, but generally, darker inks will always absorb more efficiently at this wavelength. Therefore, dark ink is the most appropriate answer, as it clearly demonstrates an enhanced interaction with the specific wavelength of 1064 nm.
