When the black light falls upon UV-visible ink, it makes the ink fluoresce so that it emits visible light, making the message readable by human eyes. [ 4 ] In some cases, people can also use photocopiers to develop UV-visible ink messages, because the scanning head of the machine emits UV light.
This is especially a property of inks with a yellow tint. Some UV-visible inks may be detected on a photocopy, due to the relatively strong ultraviolet component in light from the photocopier scanning head. Examples of inks revealed by ultraviolet light are: Laundry detergents containing optical brighteners; Soap; Body fluids, serum, saliva ...
Luminous ink under ultraviolet light Fluorescent paintings lit by black light. Black light paint or black light fluorescent paint is luminous paint that glows under a black light. It is based on pigments that respond to light in the ultraviolet segment of the electromagnetic spectrum. The paint may or may not be colorful under ordinary light.
UV Ink. The colors of ultraviolet inks are perceptible with black light, it contains printed fixed data (INE, MEXICO), images and variable data of the citizen. Weakened Pattern. The design of the security background is integrated with the border of the photograph, giving the appearance of merging this image with the rest of the credential design.
UV pinning is the process of applying a dose of low intensity ultraviolet (UV) light to a UV curable ink (UV ink). The light's wavelengths must be correctly matched to the ink's photochemical properties. As a result, the ink droplets move to a higher viscosity state, but stop short of full cure. This is also referred to as the "gelling" of the ink.
A pen is a handheld device used to apply ink to a surface, usually paper, for writing or drawing. [1] Additional types of specialized pens are used in specific types of applications and environments such as in artwork, electronics, digital scanning and spaceflight, and computing.
Extreme ultraviolet lithography (EUVL, also known simply as EUV) is a technology used in the semiconductor industry for manufacturing integrated circuits (ICs). It is a type of photolithography that uses 13.5 nm extreme ultraviolet (EUV) light from a laser-pulsed tin (Sn) plasma to create intricate patterns on semiconductor substrates.
SmartWater is a clear, water-based liquid containing an identifying code that can be viewed under ultraviolet light. [6] It is intended to be applied to valuable items, including equipment at construction sites, merchandise in retail stores, and vacant residential or commercial properties. [7]
