Screen printing remains one of the most popular and durable printing methods in the textile industry. From t-shirts and uniforms to promotional apparel and fashion garments, screen printing allows for bold, long-lasting prints that stand up to wear, washing, and repeated use. One of the most important yet often overlooked steps in this process is the creation of film positives. Without high-quality film positives, even the best press equipment and inks cannot deliver crisp, professional results.
In this article, we’ll explain what film positives are, how they are used in textile screen printing, and how InkProducts helps print professionals by offering Canon CIS systems with Film Positive ink and Epson EcoTank conversion kits with Film Positive ink—affordable, reliable solutions designed to make film output more efficient and cost-effective.
What is a Film Positive?
A film positive is a transparent sheet, typically made of polyester, that contains a solid black image of the artwork to be printed. This black image blocks light when the film is placed over a photosensitive emulsion-coated screen during the exposure process. The blocked areas remain unexposed, leaving open spaces after the screen is washed out. These openings form the stencil through which ink will later pass during printing.
The density and opacity of the black ink on the film positive are critical. If the film does not achieve sufficient darkness, light can leak through during exposure. This results in blurred, weak, or incomplete stencils on the screen. To avoid this, printers use specialized film positive ink—a formulation designed to achieve the deep, waterproof black required for clean, sharp exposures.
Why Film Positive Matters in Textile Screen Printing
In textile screen printing, precision is everything. A poorly made stencil can waste screens, ink, and valuable production time. Film positives ensure:
-
Accurate Stencils – The artwork on the film translates directly to the stencil. Clean film positives mean sharp, detailed stencils.
-
Vibrant Prints – Proper opacity ensures solid ink coverage, allowing for bright, durable prints on textiles.
-
Consistency – High-quality film positives allow printers to replicate the same design across multiple screens without variation.
-
Efficiency – With good films, fewer screens need to be redone, saving time and reducing costs.
For multi-color designs, film positives are even more important. Each color requires a separate film, and precise alignment of those films ensures perfect registration on press. Without reliable film positives, achieving professional-quality results becomes nearly impossible.
Traditional Film Output vs. Modern Inkjet Film Printing
In the past, film positives were often produced using imagesetters or laser printers. While effective, these methods required expensive equipment, specialized consumables, and often limited artwork size.
Today, inkjet printers equipped with film positive ink offer a more affordable and flexible solution. Wide-format inkjet printers can produce large films suitable for oversized designs, while desktop units handle smaller jobs quickly. With the right ink, these printers can achieve the dense, waterproof black needed for screen exposure at a fraction of the cost of older systems.

Benefits of Choosing InkProducts for Film Positive Ink
When it comes to film positive output, not all inks are created equal. Standard black ink may appear dark on paper but often lacks the opacity and waterproof qualities required for screen exposure. InkProducts Film Positive ink is specifically engineered for this purpose, ensuring:
-
Maximum density and opacity to block UV light completely.
-
Waterproof durability so the film doesn’t smear or run during handling.
-
Sharp image edges for precise screen stencil detail.
-
Compatibility with Canon CIS systems and Epson EcoTank printers.
By providing purpose-built solutions, InkProducts helps textile screen printers cut costs, improve quality, and streamline their workflow.
Why This Matters for the Textile Industry
The textile industry thrives on creativity and consistency. Customers demand bold, detailed prints that hold up to repeated washing, while printers need efficient processes to stay competitive. Film positives are a vital part of this chain, linking digital artwork to physical prints on fabric.
By using InkProducts Film Positive ink with Canon CIS systems or Epson EcoTank conversion kits, printers can:
-
Lower their production costs.
-
Gain control over film output.
-
Produce high-quality stencils in-house.
-
Avoid reliance on expensive outside film suppliers.
Whether you’re a startup screen printer or an established textile manufacturer, having reliable, affordable film output solutions is a key step toward consistent success.
Conclusion
Film positives are the backbone of textile screen printing, ensuring that every design transfers cleanly and accurately from artwork to fabric. Without properly made films, even the most advanced presses and inks cannot achieve professional-quality results.
