Procart Invisible UV Black Light Ink for Inkjet Printers - Invisible

In this review of the Procart Invisible UV Black Light Ink for inkjet printers, the conclusion is straightforward: this 10 ml white fluorescent ink is best for users who need a discreet security or branding solution that becomes visible only under UV. The reviewer found it reliably invisible in normal light while producing bright fluorescent results under a 365 nm black light, making it a practical option for document protection, property marking, and creative decorations where secrecy matters. Setup is simple for anyone familiar with refillable inkjet cartridges, and the chemical stability under sunlight, water, and heat is a notable advantage.

Key Features

• Inkjet compatibility: Formulated specifically for refillable inkjet cartridges so prints can be produced with standard inkjet printers.
• Invisible in normal light: Prints remain unseen by the naked eye under ambient lighting, revealing detail only under a 365 nm UV lamp.
• Fluorescent response: The white fluorescent pigment reacts best at 365 nm, producing a bright visible image under a black light for easy verification.
• Durability: The ink resists sunlight, water and heat so printed marks retain fluorescence without rapid fading or evaporation.
• Security and marking: Useful for document protection, anti-counterfeiting marks, tickets, labels and property marking where secret verification is required.
• Multiple colors in range: Part of a fluorescent family available in white, cyan, magenta, yellow, light cyan and light magenta for multi-color invisible printing needs.

Who It's For

The Procart invisible UV ink is ideal for small businesses, event organizers and security-conscious users who need a covert marking method for tickets, badges, documents and product authentication. It also suits artists and venue decorators who want hidden graphics that reveal themselves under a black light for special effects.

This is not for users who lack refillable inkjet cartridges or who need visible-color printing under normal light; it also requires a 365 nm UV lamp for optimum results, so buyers who cannot provide a UV source should look elsewhere.
