How to Choose Inkjet Film for Screen Printing Plate Making

In screen printing plate making, inkjet film plays a critical role in determining exposure accuracy, image clarity, and production consistency.
However, many printing factories and buyers focus only on price or thickness, without fully understanding how inkjet film quality affects long-term production performance.

This article explains how to choose the right inkjet film for screen printing plate making, from a practical manufacturing and application perspective.

1. Why Inkjet Film Quality Matters in Plate Making

During the plate making process, the inkjet film is used to block UV light and transfer the image accurately onto the screen.
If the film does not perform consistently, common problems may occur, such as:

• Incomplete exposure

• Blurred image edges

• Inconsistent stencil quality

• Higher rejection rates in mass production

These issues are often caused not by the exposure unit itself, but by film-related factors such as coating quality, ink absorption, and dimensional stability.

Inkjet film designed specifically for screen printing plate making helps reduce these risks and improve overall production efficiency.

2. Key Factors to Consider When Choosing Inkjet Film

2.1 Thickness Stability, Not Just Thickness Value

Many buyers focus on choosing a “100 micron” film, but thickness tolerance is often more important than the nominal thickness itself.

A stable thickness ensures:

• Consistent exposure results

• Uniform contact between film and screen

• Predictable plate quality across different batches

For industrial production, controlled thickness tolerance is essential.

2.2 Black Density and Ink Absorption

High black density is critical for blocking UV light during exposure.
Inkjet film with poor coating quality may produce images that appear black but still allow light leakage.

When evaluating inkjet film, consider:

• Ink absorption balance

• Drying speed

• Smudge resistance after printing

Films optimized for high-density black output provide sharper image edges and more reliable exposure results.

2.3 Dimensional Stability During Printing and Exposure

Inkjet film should remain dimensionally stable during:

• Inkjet printing

• Drying

• Storage

• UV exposure

PET polyester base film is commonly used because of its low deformation and high stability, making it suitable for professional screen printing plate making.

3. Compatibility with Ink and Printers

Inkjet film should be compatible with commonly used inkjet printers and inks.
In most professional plate making environments:

• Pigment ink is preferred for higher black density

• Dye ink may be used for certain workflows but offers lower UV blocking performance

Always test film performance with your actual printer and ink combination before bulk purchasing.

4. Why Manufacturer Capability Matters

Beyond technical specifications, the manufacturer behind the film plays a major role in long-term reliability.

A real manufacturer can provide:

• Stable batch-to-batch consistency

• Controlled production processes

• OEM customization options

• Long-term supply support

Working directly with an inkjet film manufacturer reduces sourcing risks compared to buying from trading companies.

5. Practical Checklist Before Bulk Orders

Before placing a bulk order, consider the following checklist:

• Is the film designed specifically for plate making applications?

• Is thickness tolerance controlled, not just nominal thickness?

• Does the film produce high and stable black density?

• Is batch consistency guaranteed for repeat orders?

• Does the supplier support OEM or long-term cooperation?

This approach helps avoid production interruptions and quality issues in the future.
