Epson i3200-A1 vs i3200-E1 vs i3200-U1: Choose the Right Printhead by Ink Type

Compare Epson i3200-A1 (aqueous), i3200-E1 (eco-solvent), and i3200-U1 (UV) printheads. Official specs on nozzle count, drop size, viscosity & compatibility. Choose the right genuine model for your pr

The Epson i3200 series is built on the PrecisionCore MicroTFP platform — a proven technology for industrial inkjet printing. While the i3200-A1, i3200-E1, and i3200-U1 share the same compact size, nozzle count, and high-resolution capability, they are engineered for different ink types.

Using the wrong printhead can lead to poor drop formation, frequent clogging, or even permanent damage.

This guide compares the three models based on official Epson specifications to help you make the right choice.

Key Differences at a Glance

i3200-A1: Optimized for Aqueous Inks

The i3200-A1 is designed for aqueous (water-based) inks, commonly used in DTF (Direct-to-Film), textile printing, and indoor signage applications.

• Ink Compatibility: Low-viscosity aqueous inks
• Viscosity Range: 3–4 mPa·s
• Binary Mode: 6 pl at 43.2 kHz

Grayscale Support:

• 3-level: 6.3 pl, 12.3 pl (21.6 kHz)
• 4-level: 3.8 pl, 6.1 pl, 9.4 pl (21.6 kHz)

Key Advantage: Smooth gradation and high image quality for color-critical applications

The i3200-A1 leverages Epson’s Variable Sized Droplet Technology (VSDT) to deliver smooth tonal transitions, making it ideal for photo-realistic printing.

i3200-E1: Built for Eco-Solvent Inks

The i3200-E1 is engineered for eco-solvent inks, which are widely used in outdoor signage, banners, and vehicle wraps due to their durability and weather resistance.

• Ink Compatibility: Eco-solvent inks
• Viscosity Range: 3–4 mPa·s
• Binary Mode: 6 pl at 43.2 kHz

Grayscale Support:

• 3-level: 6.3 pl, 12.3 pl (21.6 kHz)
• 4-level: 3.8 pl, 5.5 pl, 8.7 pl (21.6 kHz)

Key Advantage: Enhanced chemical resistance for stable performance with solvent-based fluids

While similar in drop performance to the A1, the i3200-E1 features internal materials optimized for solvent exposure, reducing the risk of corrosion or seal degradation.

i3200-U1: Designed for UV-Curable Inks

The i3200-U1 is tailored for UV-curable inks, used in flatbed and hybrid printers for rigid substrates like acrylic, glass, and metal.

• Ink Compatibility: UV inks (free radical or cationic)
• Viscosity Range: 5–7 mPa·s — significantly higher than A1/E1
• Binary Mode: 5 pl (43.2 kHz)

Grayscale Support:

• 3-level: 6 pl, 12.5 pl (21.6 kHz)
• 4-level: 3.8 pl, 6.2 pl, 9.3 pl(21.6 kHz)

Key Advantage: Flow path and chamber design optimized for high-viscosity UV fluids

The higher viscosity requirement means the i3200-U1 should not be used with aqueous or eco-solvent inks, and vice versa — using a lower-viscosity ink may cause flooding or misdirection.

Shared Platform: PrecisionCore MicroTFP

Despite their ink-specific optimizations, all three models share the same core architecture:

This common platform ensures compact integration, high speed, and consistent drop placement across applications.

⚠️ Why Ink Type Compatibility Matters

Choosing the correct printhead for your ink system is not optional — it’s essential.

• UV inks (5–7 mPa·s) are much thicker than water-based inks. The i3200-U1’s flow path is designed to handle this viscosity. Using an A1 or E1 head with UV ink risks under-ejection or clogging.
• Eco-solvent inks can degrade seals and internal components over time. The i3200-E1 and i3200-U1 use chemically resistant materials not present in the A1.
• Aqueous inks dry quickly. The i3200-A1 has optimized meniscus control to prevent nozzle plate drying during idle periods.

📌 Never assume interchangeability — even if the physical dimensions match.

How to Identify Genuine i3200-A1, i3200-E1, and i3200-U1

To avoid counterfeit or mislabeled units, always check the official product name on the printhead body:

Look for the label near the electrical interface:

"I3200-A1" → Aqueous ink systems

"I3200-E1" → Eco-solvent applications

"I3200-U1" → UV curing setups

Genuine units feature the Epson authentic label (as shown in the datasheet)
