The 532 wavelength is particularly effective for which type of ink?

The 532 nm wavelength, which falls within the visible light spectrum, is particularly effective for light ink due to its ability to be absorbed efficiently by certain pigments. Light inks often contain colors that reflect more light rather than absorb it; thus, a wavelength that is close to the green region in the spectrum can interact favorably with the pigments used in light inks.

In the context of laser treatments, the absorption characteristics of ink colors play a critical role. Lighter inks, especially those that are pastel or less saturated, have pigments that have lower absorption capacity compared to darker shades. The 532 nm wavelength is optimized to target these lighter shades, allowing for effective removal or alteration without excessive damage to surrounding tissue.

The discrepancies between ink types explain why darker or bright inks are not as effectively treated with this specific wavelength. Dark inks absorb more light, which makes them suitable for a different range of wavelengths. Bright inks, depending on their specific composition, may also not respond to this wavelength as uniformly as light inks would. Therefore, the 532 nm wavelength is predominantly effective for light inks based on its absorption dynamics with different colors and pigments used in inks.
