AOP+

AOP+ is based in London and, unlike most of the print-on-demand field, does its own manufacturing rather than outsourcing to a network of partners, which it treats as a selling point for quality control. Its specialty is all-over sublimation printing, cutting and sewing garments from fabric that's already been printed, on leggings, dresses, and other pieces where the pattern has to wrap right around the whole item rather than sit in one printed panel. That's a harder trick than a standard front-and-back t-shirt print, and it's the category where AOP+ built its reputation with more than ten thousand sellers on Shopify, Etsy, and BigCommerce.

Because everything ships from one London site, UK and EU customers see faster delivery and none of the customs friction that comes with a US-printed order crossing the Atlantic, while US buyers face a longer transit time. There are no minimum order requirements, and the base cost sits in the mid-range for all-over-print garments specifically, cheaper than a boutique private-label shop but a bit more than a generic AOP listing on a large aggregator. Good fit for a seller whose catalog leans on all-over patterns and who sells mainly to a UK or European audience.
