Puff print uses an ink with an additive that expands when heated, so the print rises into a raised, soft relief. The final height and how well the print holds together depend on how much ink is deposited, how evenly it is heated and for how long. If the heat or time on the dryer varies across a run, some prints rise less and some may be under-cured, which can lead to cracking or poor wash durability even with the same ink.

Check curing and deposit

Ask the printer how the ink is cured: dryer temperature, belt speed and how temperature on the print surface is checked. Under-cured puff prints can feel tacky, crack or lose height after washing; over-heating can scorch or make the print brittle. The ink deposit, controlled by the screen mesh and stencil thickness, affects height. Record these settings for the approved sample so bulk can be compared.

Fabric and placement

Hoodie fleece stretches in use, especially across the chest. A thick raised print is stiffer than the fabric around it, so stretching concentrates stress at the print edges. Large solid puff areas are more prone to cracking than smaller elements or designs with breaks. Discuss the artwork with the printer if the design has large solid raised areas.

Test the approved sample

Wash the sample several times with a named procedure such as ISO 6330, at the care conditions on your label, and check height, cracking and edge lifting. ISO 105-C06 covers colour fastness to laundering, and ISO 105-X12 covers rubbing, which matters for dark puff inks on light fabric. Approve a washed sample as the reference for bulk.

During bulk

Ask the printer to run a wash test on a few pieces from early bulk before printing the whole order. Set a simple height and appearance check against the approved sample.

Care label

Raised prints usually last longer if the hoodie is washed inside out and not ironed on the print. Put those instructions on the care label if testing supports them.

If the problem persists, consider a lower-profile print or embroidery for the logo.
