What You Need For The Screen Printing Process
Screen printing needs a handful of specific tools and materials if you want good prints. The gear you pick, the ink you use, and how you set up your space all make a difference.
Essential Tools And Materials
First off, you need a mesh screen stretched tight on a frame. This is where your stencil lives and where the magic happens.
The squeegee is your main tool. It pushes ink through the mesh onto whatever you’re printing. Get one that fits your screen for even coverage.
Photo emulsion is what turns your screen into a stencil. You mix it with a sensitizer, then coat your screen with it. It hardens under UV light, locking in your design.
Pick screen printing ink that matches your project. Water-based is usually easiest for beginners—soft on fabric, easy to clean.
A strong light source is needed to expose your design. Some use a bright lamp, others an exposure unit. The light sets the emulsion, so your design shows up crisp.
Cleaning is key. Soap and water work for water-based inks. Keep rags and brushes around for quick cleanups.
Choosing The Right Screen And Ink
Mesh count matters. Lower mesh (110-156) is good for thick ink and bold shapes. Higher mesh (200-280) is for fine details and thin layers.
Tighter mesh means sharper prints. Loose mesh lets too much ink through, making edges fuzzy. Always make sure your mesh is stretched tight and even.
Water-based ink is great for most beginner jobs. It dries soft, washes out of screens easily, and works best on light fabrics.
Plastisol ink is bright and tough, and works on any fabric color. It needs heat to cure, but it’s durable. If you’re making stuff for outdoors, plastisol’s a solid pick.
Match your ink to your material. Fabric ink bonds to cloth, paper ink dries fast and doesn’t smudge, and there are even special inks for glass or metal.
Setting Up Your Workspace
Pick a spot with good light and fresh air. You want to see what you’re doing, and air flow helps inks dry and cuts down on fumes.
Try to keep screen prep and printing separate. That way, wet emulsion won’t mess up your finished screens.
Your printing surface needs to be flat and steady. A big table is fine for small runs. Screen printing kits sometimes come with registration tools for lining up colors.
Keep inks and chemicals somewhere cool, away from sunlight. Water nearby helps for cleaning up water-based inks. Paper towels are a lifesaver for spills.
Arrange your tools so you’re not hunting for stuff mid-print. Squeegees, inks, and cleaners should be close by. Staying organized keeps you moving and cuts down on mistakes.

Step-By-Step Screen Printing Process
The process has four main steps that turn your design into a real, custom print. Each one needs a bit of technique and timing to get durable results on shirts and other fabric.
Preparing And Coating The Screen
Start by cleaning your screen with degreaser to get rid of oils or dust. Use a soft brush on both sides, rinse well, and let it dry all the way.
Mix your emulsion as the label says. Most need a sensitizer mixed in. Work under low light to avoid exposing it too soon.
Pour the emulsion into your scoop coater. Hold the screen up and pull the coater upward in one smooth go for an even coat.
Coat both sides—thin on the squeegee side, a bit thicker on the other. It doesn’t have to be perfect, just even enough.
Let the screen dry in a rack, coated side down, in a dark, dust-free spot. Keep it warm (86-104°F) if you can. Low humidity makes drying faster and smoother.
Exposing And Washing Out The Design
Print your design on transparency film with dark ink. It needs to be really opaque or the light will sneak through. Lay the film on the squeegee side of your dry screen.
Tape the transparency down so it doesn’t shift. Put the screen on your exposure unit, film facing the light.
Expose for the time your emulsion calls for—usually 8-15 minutes. Too little, and the emulsion washes out too easy; too much, and you lose detail.
After exposure, rinse with cool water. Let it soak a minute or two to loosen up the soft emulsion. Use a pressure washer or a strong hose to blast out the design areas.
Keep rinsing until the design is clear and light shines through the open spots.
Printing Your Design On Fabric
Set the screen on your press and line it up with your shirt or fabric. Use platen adhesive to keep the garment from shifting.
Pour ink above the design on the screen. Water-based inks give a soft feel, plastisol brings the color and durability.
Hold the squeegee at a 45-degree angle. Do a flood stroke to fill the stencil with ink, using light pressure.
Now, make the print stroke—pull the squeegee across with steady, firm pressure. That pushes ink through the stencil onto your shirt.
Lift the screen to see your print. For multiple colors, repeat with new screens and inks.
Curing And Finishing The Print
Curing is what makes your prints last wash after wash. Plastisol inks need 320°F, water-based inks cure at 300-320°F.
If you have a conveyor dryer, you’ll get even results and can handle bigger batches. The belt speed and heat work together to cure prints all the way through.
For small runs, a heat gun can do the job, but you’ve got to keep it moving or you’ll scorch the fabric.
Test by stretching a bit of the print. If the ink cracks or feels sticky, it’s not cured. Properly cured ink holds up and doesn’t peel.
Let prints cool off before stacking. Use tissue paper between shirts so they don’t stick in storage.
Tips For Better Prints And Fewer Mistakes
Good screen prints come from dodging common mistakes, taking care of your screens, and upgrading gear when it’s time. These things all help keep your prints sharp and your process smooth.
Common Screen Printing Errors To Avoid
Registration problems trip up a lot of beginners. Always use three registration marks—two up top, one at the bottom. It’s faster and more accurate than just using one or two.
Don’t tape off your registration marks before you print. Register your job first, then tape them out. It’s a small thing, but it saves headaches later.
Squeegee technique matters. A dull blade leaves thick, messy ink instead of clean lines. Swap or sharpen blades every 10,000 prints on automatic presses.
Keep your pressure steady. Too much, and you’ll push fabric fibers down and get marks, especially on dark shirts. Too little, and you’ll miss parts of your design.
Exposure times change with mesh count. You can’t use one time for every screen. 110 yellow mesh and 305 yellow mesh need different exposures. Colored mesh takes about twice as long as white mesh.
Bad color mixing leads to weird prints. Skip Pantone formulas with fluorescent inks—they’re sticky and mess with your prints.
How To Clean And Reuse Screens
Clean screens right after printing so ink doesn’t dry in the mesh. Use the right cleaner for your ink—plastisol and water-based inks need different stuff.
Take off the emulsion with remover when you’re done. Coat both sides, let it sit, then scrub gently so you don’t wreck the mesh.
Degrease screens before you re-coat them. Degreaser gets rid of oils and dust, so the new emulsion sticks and doesn’t get pinholes.
Check for pinholes or mesh damage before using screens again. Patch small holes with filler, but if the mesh is torn or worn out, just replace it.
Store clean screens somewhere dry. High humidity messes with emulsion and exposure. If you’re picky, use a hygrometer to check your storage area.
When To Upgrade Your Screen Printing Equipment
If sharpening your squeegee doesn’t help anymore, or it’s warped or nicked, it’s time for a new one.
Switch to LED exposure units if you’re still on old-school fluorescent or metal halide. LEDs give you consistent exposures and use less power. They’re great for SBQ polymer emulsions.
If you’re printing 100+ pieces per job, consider an automatic press. It speeds things up and keeps prints consistent.
A heated drying cabinet can dry screens in 15 minutes instead of hours, and the humidity stays steady for better exposures.
Go for finer mesh (like 305) if you want sharper detail, but remember you’ll need to tweak your squeegee pressure and ink mix.
Replace old pallets and registration gear if alignment gets tough. Worn pins or loose parts make registration a pain.
