What durability testing on decoration actually involves
A decorated garment that fades after twenty washes is a refund waiting to happen. Here is the test protocol we run on every base before adding it to the catalogue.
A decorated garment that fades after twenty washes is a refund waiting to happen. A garment whose seams give before the decoration does is the same thing in a different order. Both cases damage the brand more than they damage us. Below is the test protocol we run on every base before we add it to the catalogue, and that we re-run quarterly to catch supplier drift.
Wash-cycle testing. Each candidate base is decorated using each compatible decoration method (DTG, screen, embroidery, sublimation as applicable) and run through fifty wash cycles at 30 degrees C, tumble dry low. After cycles 5, 10, 25, and 50, the piece is graded against three criteria: print colour density (visual against a reference card), garment dimensional stability (measured in cm against the new garment), and seam integrity (visual inspection of stress points).
Pass criteria. A base passes if colour density at cycle 50 is at least 90 percent of cycle 1, dimensional shrinkage is under 5 percent, and no seam failures are observed. Anything below those numbers gets a written note explaining what fails and at what cycle. We sometimes still stock such bases but with a documented caveat (e.g., "recommended for promotional drops where wash count is low").
UV exposure test (for outdoor-use items). Stickers, posters, and outdoor caps are exposed to controlled UV light equivalent to three years of outdoor use, then graded for fade and lamination peel. This adds a week to onboarding for outdoor-positioned products but prevents the predictable customer-service avalanche later.
Drop test (for drinkware). Ceramic mugs and stainless tumblers undergo a controlled drop test from a fixed height onto laminate and tile surfaces. Failure here is not just breakage; small chip propagation that does not show at unboxing but emerges after the first dishwasher cycle counts as failure.
Supplier drift surveillance. Bases that pass initial testing are re-tested every quarter on a sampled basis. Supplier dye lots shift; manufacturing tolerances drift; the base that tested clean in March may have a different feel in October. Re-testing catches this before customers do.
What we publish. The current test status of every base in our catalogue is available to onboarded partners as part of the base sheet. If you want to see the test results for a specific SKU before ordering, ask in your onboarding brief and we will include them in the reply.
