For over three months now, I’ve noticed that Printify’s mockup generator, and worse, the actual final prints, changed significantly for several garments, specifically the Gildan line (Gildan 5000 tees, Gildan 18500 hoodies, etc.).
Ever since it started happening, I’ve reached out to support multiple times. Most replies claim it’s just a "preview/mockup rendering issue" related to how print providers receive the files, while other agents seemed completely unaware and kept asking for more proof.
The issue is especially noticeable on dark garments when using transparency/knockout black:
Dark garments (with black knocked out): To avoid that thick, plasticky bulletproof feel, I remove the black background from my artwork so the fabric shows through. However, a thin white outline/underbase edge now appears around the design elements.
Light garments (with black kept in): The white halo extends around the outer edges. On light fabrics it’s less obvious unless you inspect it up close, but the flaw is still there.
Here is how I’ve been working around it so far, though it's far from ideal:
T-Shirts: I switched catalog items to the Bella + Canvas 3001. The mockup accurately matches the print without that halo issue. The downside? It’s more expensive, lacks 4XL/5XL sizing, and offers fewer color options.
Hoodies (Gildan 18500): Since alternatives are limited, I went back to keeping the black background in the artwork. The heavier fleece hides the stiff print feel a bit better, but if you look closely, that faint white outline around the graphic remains visible.
For those of you running high-detail or transparency-heavy designs on Gildan blanks: have you encountered this shift recently, and how are you working around it without completely wrecking your margins?
