Take the Guesswork Out of Screen Coating | Saati ProCoat Screen Auto Coaters

You don’t have to overhaul your shop to start automating. If your team is coating dozens of screens a day, feeling the pressure to stay consistent, or losing time to screen failures, that’s your signal. Upgrading your darkroom equipment with an automatic screen coater is one of the smartest steps toward shop automation. It plugs into your current workflow, fits your existing screen sizes, and immediately boosts stencil consistency without needing to change anything else in your setup.

Manual coating works, but only up to a point. Hand fatigue, uneven scoop coater pressure, and operator-to-operator differences always introduce variables into your emulsion deposit. When your darkroom needs to keep pace with an active automatic press or a busy manual shop, automatic screen coating helps you work faster, coat smarter, and eliminate costly stencil mistakes before screens ever hit the press.

Automated Emulsion Coating Fits Any Shop Size

Every darkroom faces unique space and production requirements. Some print shops need maximum screen output in tight windows, while other shops have tight floor plans where every square inch of space counts. Adding automated screen coating used to require massive darkroom space and major electrical upgrades. Today, SAATI builds automatic screen coaters designed directly for growing screen printing operations.

Whether you need compact automation for a tight darkroom layout or high-throughput dual-screen production, automated coating delivers identical emulsion profiles hour after hour. Eliminating manual coating variables means predictable exposure times, cleaner detail resolution, and faster washout performance across every job you run.

SAATI ProCoat Mini Compact Single Screen Coater

The SAATI ProCoat Mini Automatic Screen Coater brings automated emulsion coating to print shops where floor space and budget matter most. Designed as SAATI's smallest-footprint single-screen coater, the Mini automatically coats one screen up to 28" x 40", accommodating standard 20" x 24", 23" x 31", and 25" x 36" wood, aluminum, or roller frames.

Operating on standard 110V power and simple shop air, the ProCoat Mini fits right into smaller darkrooms without requiring electrical upgrades. Its programmable touchscreen controls allow operators to set dwell time, number of emulsion passes, and coating speed independently by side. Servo-driven coating movement delivers ultra-smooth carriage travel, producing repeatable stencils while reducing manual coating labor.

• Compact Darkroom Footprint: Fits tight shop spaces easily with or without the included floor stand
• Programmable Touchscreen: Save dwell times, speed, and passes for precise emulsion control
• Servo-Driven Carriage: Smooth mechanical movement ensures flat, repeatable emulsion deposits
• Pneumatic Frame Clamps: Dual pneumatic clamps lock frames in place securely during coating cycles
• Simple Setup: Plug-and-play installation requiring standard 110V power and 80 PSI air supply

SAATI ProCoat Dual Screen Auto Coater High Output

When high production demand requires maximum darkroom speed, the SAATI ProCoat Dual Screen Auto Coater handles two screens simultaneously with exact mechanical precision. It accommodates frame sizes from 20" x 24" up to 25" x 36", effectively doubling your coating output without doubling your darkroom labor hours.

This dual-screen coater features intuitive foot pedal controls for quick hands-free frame loading, giving operators a smooth, efficient rhythm when prepping large screen batches. Consistent emulsion laydown from top to bottom means cleaner stencil edge definition on detail prints and hassle-free reclaiming in the washout booth.

• Dual-Screen Capability: Coat two screens simultaneously to keep up with busy production schedules
• Hands-Free Foot Pedal Control: Streamline screen loading and keep darkroom operations moving fast
• Consistent Emulsion Laydown: Smooth, controllable coatings reduce pinholes and reclaim headaches
• Flexible Frame Range: Easily handle standard 20x24, 23x31, and 25x36 screen frames

Consistency That Drives Shop Profitability

Coating speed means nothing without consistency. Automatic screen coaters lay down smooth, controllable emulsion layers that expose sharp detail, resist press friction, and reclaim smoothly. Every screen comes out identical regardless of who is working the darkroom shift. That level of repeatability improves every step downstream, from exposure unit times to ink transfer on press.

Adding automated screen coaters like the SAATI ProCoat series fits directly into your screen printing workflow. Simple daily maintenance, predictable emulsion thickness, and reliable operation keep your team focused on producing top-tier prints. For high-volume darkrooms coating over 50 screens a day, automated coating pays for itself in time savings, chemical efficiency, and reduced stencil downtime.

Choose the Right SAATI Coater for Your Screen Room

Deciding between the SAATI ProCoat Mini and the SAATI ProCoat Dual Screen Auto Coater comes down to your daily screen volume and available darkroom footprint. The ProCoat Mini offers a compact footprint ideal for growing manual shops or tight screen rooms needing single-screen consistency. The ProCoat Dual Screen Coater gives high-volume shops the muscle to coat twice as many screens in less time.

Both coaters eliminate the physical strain of manual coating while upgrading overall stencil quality.
