At Pulse Merch in Cedar City, we run puff screen printing for Southern Utah clients who want a bold, raised logo that reads well from across a room, but only when the job can tolerate a heavier ink deposit and a properly controlled cure. The single control that decides whether a puff run succeeds is simple to name and easy to skip: enough ink on the shirt, cured at the correct surface temperature, checked with a probe rather than guessed from the dryer dial. If a design or fabric cannot support that deposit, we run a sample first or steer the client toward embroidery instead.
What you need: inks, additives, mesh, squeegee, dryers, and measuring tools
Puff results come down to how much ink sits on the shirt and whether that ink film reaches the right temperature all the way through. Everything on your press either helps build that deposit or works against it.
Premixed, ready-for-use puff bases are the simpler route for shops that don’t run puff often. Puff additive mixed into standard plastisol at 5 to 20 percent by weight gives more control over color matching, which matters when a client’s brand guide specifies an exact Pantone. The tradeoff is that additive mixes need accurate weigh-ins; eyeballing the ratio is how shops end up with inconsistent loft between batches.
Mesh and squeegee choices matter just as much as the ink. Lower mesh counts, generally 86 to 110 threads per inch, let more ink pass through the stencil, and a thicker emulsion buildup on the screen adds even more room for deposit. Pair that with a softer squeegee, around 60 to 65 durometer, which flexes enough to push a heavy ink film without scraping it back off the shirt.
A few equipment notes worth checking before you commit to a run:
- Use a donut probe or laser surface thermometer to confirm ink-film temperature, since dryer air settings never tell you what the ink itself reached.
- Choose mesh in the 86 to 110 range for puff work; higher mesh counts starve the deposit and flatten the finished print.
- Keep a soft squeegee dedicated to puff jobs so you’re not fighting durometer inconsistency between runs.
Pro Tip: Keep a written run sheet for every puff job, mesh count, additive percentage, stroke count, and confirmed surface temperature, so a second shift can reproduce the same result without guessing.
Design and artwork rules for reliable puff
Puff ink expands, and expansion punishes fine detail. Artwork built for flat printing usually needs revision before it goes on a puff screen.
- Keep strokes and text thick; thin lines lose their shape as the ink rises and spreads.
- Avoid halftones and small dot patterns entirely, since puff ink cannot hold fine detail once it expands.
- Break large solid fills into a dotted or spaced underprint pattern, which gives the expansion somewhere to go instead of pulling against the fabric.
- Expect color to shift once puff overprints another layer, because the raised ink film changes opacity and hue compared to a flat pass.
- Check registration tolerance and stencil depth in your file setup, since a puff stencil holds more emulsion than a standard one and needs extra clearance.
Color matching deserves its own mention here. A client-approved Pantone on a flat proof will not look the same once it’s under half a millimeter of raised plastisol. We tell clients up front that puff softens and shifts color, and we push for an in-hand sample approval before a full run rather than relying on a screen proof alone.
Print process: setup, printing strokes, flashing, and curing to activate puff
Getting loft right on press is a sequence, not a single setting. Skip a step and the print either goes flat or blows up unevenly.
Start with off-contact slightly higher than a standard flat print, then run a heavy flood stroke to load the screen before your print strokes. From there, use a controlled number of firm print strokes rather than one aggressive pass. Excess squeegee pressure forces ink into the fabric instead of leaving it sitting on top, which is the fastest way to lose loft before the shirt ever reaches the dryer.
Flashing is where a lot of puff jobs go wrong. You want the ink gelled just enough to hold shape for the next screen, not fully activated. Minimizing flash dwell keeps the expanding agent inactive until the print reaches the conveyor dryer, where it belongs. Flash too long or too hot and you get partial puff under the flash unit, which throws off registration on every layer printed after it.
The final cure is where deposit becomes loft. Most puff plastisol chemistries need a surface ink-film temperature between 290°F and 330°F, and that range has to be confirmed on the ink itself, not read off the dryer’s air temperature dial. A donut probe laid directly on the printed area during a test pass is the only reliable way to know what the ink actually reached.
A few points to keep in mind on cure:
- Under-cure leaves puff soft, tacky, and prone to washing out early.
- Over-cure or excess dwell time tends to collapse the puff or make it brittle and cracked.
- Air temperature on the dryer display is not the same number as ink-film surface temperature.
Standard puff plastisol chemistries cure between 290°F and 330°F, and that window shifts on performance polyester, where a lower-cure puff formula may be needed to protect the garment’s dye stability.
Common problems and fixes: flat puff, collapsed puff, puckering, registration
Most puff complaints trace back to one of four causes, and each has a specific fix rather than a guess.
Flat or weak puff usually means not enough ink reached the shirt. Check your mesh count first, since anything above 110 starves the deposit, then check squeegee pressure and confirm the cure actually hit the manufacturer’s surface temperature rather than just the dryer’s set point.
Collapsed or brittle puff points the other direction. Excessive heat or dwell time is the most common cause, and the fix is shortening dryer time or dropping the belt speed slightly, then reverifying with a probe. If the print is still failing after a temperature adjustment, check your additive percentage; too little additive in a custom mix weakens the ink film’s ability to hold its shape once it expands.
Puckering shows up almost exclusively on stretchy or textured fabrics. Solid puff fills pull against Lycra or performance blends as the ink expands, and the fix is converting the art to a dotted or spaced underprint rather than fighting it on press. On heavier 100 percent cotton, this is rarely a problem.
Registration drift on multi-color puff jobs is almost always a flash issue. If the puff layer partially activates under the flash unit, it swells slightly before the next screen hits, throwing off alignment on every layer after it. Shortening flash dwell usually solves it.
- Flat puff: check mesh count, squeegee pressure, and confirmed cure temperature.
- Collapsed or brittle puff: reduce dwell time or temperature, then recheck additive ratio.
- Puckering: switch solid fills to a dotted underprint, especially on stretch fabric.
- Registration drift: shorten flash dwell so the puff layer doesn’t activate early.
Pro Tip: When a test print shows any of these symptoms, stop and adjust one variable at a time rather than changing mesh, ink, and cure settings all at once, or you won’t know which fix actually worked. Our production guide to what makes a great screen print covers the same troubleshooting logic for flat prints, if you want the broader context.
Pulse Merch shop notes: real problems we see and what we tell clients
A local gym came to us wanting a large puff logo across the back of a moisture-wicking performance tee. The art was a solid block letter, and on the sample run, the fabric puckered badly around the edges the moment the puff expanded. We rebuilt the design with a dotted underprint and dropped the coverage slightly, and the second sample held flat. That job is why we push sample runs on any stretch or performance fabric before committing to a full order.
The most common customer mistake we see is expecting fine detail, small text, thin outlines, or a photo-style logo, to survive puff expansion the way it would on a flat print. It won’t. We also see clients skip the sample stage entirely because they’re in a rush, then call back a week later asking why the print cracked after two washes. Skipping the sample is almost always the more expensive choice in the long run.
Every puff job goes through checks including a sample pass with a probe reading confirmed against the ink manufacturer’s spec, a visual check for loft and edge quality, and a wash test before the full run gets approved. If a client’s design calls for small logos on workwear that needs to survive years of laundering, we’ll often recommend embroidery instead of puff, since it holds detail and durability better on that kind of garment.
When to choose puff screen printing versus embroidery or flat screen prints for business orders
Puff earns its place on retail-facing apparel: event shirts, band merch, and bold brand logos where the raised texture is part of the visual impact. It’s a look, not just a mark, and it works best on heavier cotton where the ink has something stable to expand against.
For small, durable logos on workwear, jackets, or polos that need to survive years of laundering and abrasion, embroidery holds up better and keeps fine detail that puff can’t. Our guide to screen printing on workwear goes deeper on that tradeoff.
Run size matters too. Puff screens take more setup time to dial in loft correctly, so it pencils out better on mid-to-large runs where that setup cost spreads across more shirts. Avoid puff on very stretchy or textured fabrics unless the art has already been adjusted for it. When we quote a job, we usually present both a puff option and a flat or embroidered alternative side by side, with a sample approval step before either goes into full production.
Practical final checklist for long-term durability
Before any puff job leaves our shop, we run through the same five checks: mesh count matched to the deposit needed, ink film thick enough to hold loft, cure temperature confirmed with a probe on the actual print rather than the dryer readout, a signed-off sample in hand, and a garment that can physically support the expansion without puckering.
At quote time, we talk wash care and sample approval before we talk price, because a client who skips the sample step is the client most likely to call back with a complaint. The habit that saves the most rework is boring but effective: measure the ink’s surface temperature, never the dryer’s air temperature, on every single run.

Puff printing is one of the decoration methods we run in-house at our Cedar City shop, which means the mesh, additive ratio, and cure settings on your job get dialed in by the same team from first proof to final cure, not handed off to a subcontractor. If you’re weighing puff against embroidery or a flat print for an upcoming order, we’ll walk through the tradeoffs with you before you commit to a full run.
To get an accurate puff estimate, send us:
- Garment type and fabric content, since stretch blends need art adjustments puff on cotton doesn’t.
- Your artwork file, along with placement and finished size.
- Run size, so we can price setup against volume correctly.
Start with a quote request or ask about a sample run before you lock in quantities. You can also read more about our screen printing process if you want the full production picture first.

FAQ
What is puff screen printing?
Puff screen printing uses a plastisol ink mixed with a foaming or expanding agent that rises when heated, creating a raised, three-dimensional texture on the printed design. It’s applied through the same screen printing process as flat prints, with adjustments to mesh, ink deposit, and cure to activate the expansion.
How much does a puff print machine cost?
Puff printing doesn’t require a separate machine. It runs on standard screen printing presses and conveyor dryers, with the added need for a donut probe or laser surface thermometer to confirm the ink film reaches the manufacturer’s specified cure range, generally 290°F to 330°F.
Is puff print more expensive than flat screen printing?
Puff typically costs more per print because it uses a heavier ink deposit, sometimes a specialized puff additive mixed at 5 to 20 percent, and requires more careful cure control to avoid a failed run. The added setup and testing time on puff jobs also tends to add cost compared to a standard flat print.
What is the difference between screen print and puff print?
Standard screen printing lays down a flat, thin layer of ink that sits close to the fabric surface. Puff printing uses a thicker ink deposit with an expanding agent that rises during the cure, creating a raised texture, though it sacrifices fine detail that flat prints can hold.
