Customer Questions & Answers

  • Question: What is the Opticz UV Blacklight Reactive Invisible Blue Ink used for?

    Answer: The Opticz UV Blacklight Reactive Invisible Blue Ink is primarily used for marking documents or items securely. This ink is invisible under normal lighting but becomes visible under UV blacklight, making it ideal for security applications such as watermarking, authentication, and anti-counterfeiting measures. This is especially useful in sectors such as event management to mark tickets or in retail to verify product authenticity.
  • Question: How does the invisible ink work?

    Answer: Invisible ink works by utilizing UV-reactive pigments that are invisible to the naked eye. When exposed to a UV blacklight, the ink fluoresces, revealing the marks or stamps. This technology allows for discreet markings that can prevent unauthorized reproduction or fraud. It’s commonly used in security tagging, covert operations, and even creative arts where invisible applications are desired.
  • Question: Is the ink safe for use on skin?

    Answer: The Opticz UV Blacklight Reactive Invisible Blue Ink is designed primarily for document marking and similar applications. It is not recommended for use on skin as the safety of contact with dermal layers is not specified. Users looking for skin-safe options should explore specific skin inks or markers available in the market, ensuring they meet skin safety standards.
  • Question: Can I see the marks made by the ink without a blacklight?

    Answer: No, the marks created using the Opticz UV Blacklight Reactive Invisible Blue Ink are designed to be invisible under normal lighting conditions. For visibility, a UV blacklight is needed, which activates the fluorescing agents in the ink. This feature allows for secure markings that do not attract attention until they need to be revealed, making it perfect for confidential or sensitive information.
  • Question: What surfaces can this ink be used on?

    Answer: The Opticz UV Blacklight Reactive Invisible Blue Ink can be applied to various surfaces, including paper, cardboard, wood, and certain plastics. However, it is advisable to test on a small area first to ensure optimal adherence and effectiveness. This versatility makes it suitable for applications ranging from document verification to creative projects where invisible marking is desired.
  • Question: How long does the ink last once applied?

    Answer: The longevity of the ink depends on several factors, including the type of surface it’s applied to and environmental conditions. Generally, when applied properly, the marks can last for an extended period without fading. This durability is crucial for applications in security and fraud prevention, as longer-lasting markings help maintain authenticity over time.
  • Question: Is the ink permanent once it dries?

    Answer: Yes, once the Opticz UV Blacklight Reactive Invisible Blue Ink dries, it forms a permanent bond with the surface it is applied to. This permanence is essential in security applications where tampering or removal could lead to unauthorized access or fraud. Once dry, the markings remain intact unless intentionally removed through abrasive methods.
  • Question: Can I mix this ink with other types of ink?

    Answer: It is not recommended to mix Opticz UV Blacklight Reactive Invisible Blue Ink with other types of inks as this could alter its UV-reactive properties and performance. Mixing might compromise the ink's ability to fluoresce under UV light. For best results, it’s advisable to use this ink alone for all applications requiring its unique security features.
  • Question: Where can I buy Opticz UV Blacklight Reactive Invisible Blue Ink Hand Stamping Document Marking Security Kit Pro Kit in Bangladesh?

    Answer: You can purchase the Opticz UV Blacklight Reactive Invisible Blue Ink Hand Stamping Document Marking Security Kit Pro Kit from Ubuy. Ubuy offers a convenient online shopping experience, allowing you to browse the product details and make your purchase from the comfort of your home.
  • Question: Is this product suitable for kids' crafts?

    Answer: While the Opticz UV Blacklight Reactive Invisible Blue Ink can be enticing for crafts, it is not specifically designed for children’s use. Adult supervision is recommended, and users should ensure appropriate safety measures are in place, especially since it is intended for secure marking applications. Always check for suitable alternatives that are specifically designed for kids.

Opticz Stamps & Stamp Supplies Editorial Review

This product is a set of fluorescent markers with invisible ink and a blacklight keychain. The ink is alcohol-based and Considered semi-permanent, making it very difficult to remove. It works best on porous surfaces, but can also work on non-porous ones with ample drying time. The included keychain light uses a replaceable LR44 battery. While the ink is almost invisible in regular light, it glows brightly under blacklight. Some colors may appear more white than colored, and the markers come in both regular and fine-tip versions. Customers have used these markers for various purposes, such as marking items for an annual contest and in the props department for resetting after a take. Customers appreciate the product's effectiveness and price, but some have reported issues with ink longevity and non-responsive customer service when seeking a replacement flashlight.
