Screen Print Direct UV Blocking Ink Refill 1 LTR - High Opacity Black

In this review of the Screen Print Direct Black Out Universal Inkjet Ink Bottle, the bottom line is simple: this 1 LTR refill is built for screen printers who need a true UV blocking, high-opacity black for film positives. The reviewer found it particularly valuable for stencil preparation because it delivers an Optical Density of 5.0 and dries quickly on waterproof inkjet film, cutting down wait time between prints. For anyone producing film positives at home or in a small shop and aiming for crisp, reliable blocks of black, this refill is a practical, purpose-built choice.

Key Features

• UV Blocking: Formulated to prevent UV light from passing through film positives so screens expose clean, sharp images.
• Optical Density 5.0: Very high opacity delivers deep, true black coverage that helps create consistent, professional stencils.
• Fast Drying Time: Dries quickly on inkjet film, allowing faster workflow and less risk of smudging during handling.
• Reliable Jetting: Designed for printers with multiple print heads and engineered to maintain smooth flow without frequent clogs.
• Non-Yellowing: Dyes and pigments are formulated to stay stable so positives retain their tonal integrity over time.
• Made in U.S.A.: Domestic manufacturing offers predictable quality control for production environments.

Who It's For

The product is aimed at screen printers, small print shops, and experienced hobbyists who produce film positives and need a dependable blackout ink with high Optical Density and fast drying. It works well for users who already run inkjet printers from brands like Epson, Canon, HP, or Kodak and want to upgrade to film-specific refill ink without changing their printer setup.

It is not intended for general paper printing or casual home photo use; this is a specialized ink formulated for film positives and screen printing workflows, so those looking for inexpensive paper ink substitutes should look elsewhere.
