Depends on the ink. Some are effected more than others. We currently have an issue with the UV light from a finishing lacquer process bleaching the magenta ink giving the final print a green tint! Not idea...
We are looking at changing the ink supply as this didn't effect the ink we used previously. There is not much else you can do.

How does UV curing work and what are its applications in various industries?
UV curing is a process where ultraviolet light is used to instantly cure or harden materials like inks, adhesives, and coatings. This is achieved by a chemical reaction called photopolymerization. UV curing is commonly used in industries such as printing, automotive, electronics, and medical devices for applications like printing, bonding, and coating.
Are UV light and UV rays the same thing?
Yes, UV light and UV rays refer to the same thing - ultraviolet radiation. UV radiation is a type of electromagnetic radiation that is not visible to the human eye. UV light or UV rays are terms used to describe this form of radiation.

How does the sun affect ink?
When ink is exposed to sunlight it can be bleached out by it due to the UV-rays of the light. The energetiv UV-light is able to split up oxygen molecules O-O into so called radicals O2 --UV--> 2 O. this atomar oxygen is very reactive an destroys the ink, more chemically: it oxidises the ink. It's in a way quite the same when you're washing clothes with bleach to remove tomatoe taints or so - there are formed radicals from the bleach which oxidise the color molecules of the tomatoe and destroy it this way to leave a bright piece of cloth after wash.
What makes UV printing services in Pakistan stand out from traditional printing methods?
UV printing offers several advantages over traditional printing methods, which is why it’s quickly becoming the go-to solution for businesses in Pakistan. Here’s what makes UV printing stand out: Faster Drying Times: Traditional printing methods typically rely on evaporation or absorption to dry the ink, which can take hours. In contrast, UV printing uses ultraviolet light to instantly cure the ink, significantly speeding up the production process and reducing waiting times. Enhanced Print Quality: UV printing produces vibrant, sharp, and high-resolution prints that are far superior to what can be achieved through traditional methods. The prints are resistant to fading, ensuring that colors remain bright even when exposed to light and weather conditions. Ability to Print on Diverse Materials: UV printing can be used on almost any material, including non-porous surfaces like glass, acrylic, metal, and plastic. This versatility allows businesses in Pakistan to create customized products, signage, and promotional items that traditional printing methods cannot handle. Eco-Friendly: Traditional printing often involves chemicals and solvents that are harmful to the environment. UV printing uses less ink and fewer solvents, making it a more eco-conscious option for businesses seeking sustainable solutions. Durability: UV-printed materials are highly durable and resistant to wear and tear, making them perfect for products that need to withstand harsh conditions. Whether it's outdoor signage or industrial labels, UV prints hold up better than traditional printed materials. These advantages make UV printing an appealing option for businesses across Pakistan looking for efficient, high-quality, and eco-friendly printing solutions.

Why does tonic water not glow when mixed with green highlighter ink?
Tonic water does not glow when mixed with green highlighter ink because the quinine in tonic water, responsible for fluorescence under UV light, is not reactive to the wavelength of light emitted by the green highlighter ink. The fluorescent properties of quinine are specific to certain wavelengths of UV light, which the green highlighter ink does not produce.
What is photocurable polymer?
They are polymers often used with inks and also tooth repair. The monomers chosen are those that will polymerize on exposure to UV light radiation. In the case of an ink, after it is applied it is usually passed under a UV light to cure it. Similarly, after the tooth is filled, UV light is applied to harden it.
