The Most Underrated Piece of Gear in the Shop: The Auto Coater

“I can coat a screen faster than that machine.”

Yep—heard that one a hundred times. And yeah, you’re probably right. You can coat faster. But here’s the real question: can you coat better?

The auto coater is one of the most overlooked pieces of equipment in a screen printing shop. It’s not flashy. It doesn’t spin around and print shirts. But if you’re trying to scale, automate, or just stop wasting time troubleshooting stencil issues—this thing is a game-changer.

Let’s be real for a sec. Manual coating is inconsistent. Everyone has their own “style.” One hand, two hands, speed, pressure, how tired you are that day?—it all affects the screen. That means my screen won’t be the same as yours, and yours won’t be the same as the next press op’s. That’s not a skill issue, that’s just human nature.

But the screen—and more specifically, the stencil—is the heart of this whole process. If that part’s not dialed, everything downstream can go sideways. Pinholes, uneven ink deposits, breakdowns mid-run… we’ve all been there.

Here’s where the auto coater shines: consistency. Every screen. Every time.

It lays down emulsion with a controlled, repeatable coat. You’re not guessing how much emulsion is going on. You’re not wondering if this screen is gonna break down halfway through the run. You’re getting consistent EOM (emulsion over mesh), which directly impacts how your ink sits, how it prints, and how cleanly it clears.

And here’s the bigger picture: when your screen room is dialed in, the press floor moves smoother. Fewer variables. Fewer surprises. More care and time spent in the screen room means faster setups, fewer hiccups, and way more productive print days. Period. What slows you down isn’t the time it takes to coat a screen—it’s the time wasted fixing what wasn’t done right in the first place.

You want better prints off the press? Start with better screens.

You want better screens? Get yourself an auto coater.

It’s not about speed. It’s about dialing in a process you can rely on. One less variable. One more step toward true production control.

So next time someone says, “I can coat faster than that,” just nod and smile—and remember that we’re not in a race, we’re in a business. And good business is built on repeatable results.
