TDA is a privately held corporation founded in 2004, rebuilt in 2026 for the shops actually doing the work. We serve the global decorated-apparel community with professional education, industry certification, and the tools owners need to price, sell, and produce with confidence.
Our membership spans screen printers, embroidery shops, DTG and DTF producers, sign shops, and the suppliers who equip them. Members represent over 100 countries, and our platform serves millions of page views annually.
Everything TDA builds serves one of three goals: raise the floor on knowledge, prove competency to the market, and connect the shops doing the work.
The Certified Decorator Professional program is the only credential in the industry for verifying a decorator's general knowledge of standards, practices, and procedures.
The education division of TDA, dedicated to making professional screen printing education accessible to anyone with a press and an internet connection.
The TDA Institute's Diploma in Screen Printing Course was created in September 2013. Since then, hundreds of students throughout the US and worldwide have enrolled.
Study screen printing techniques at your own pace from anywhere in the world. No geographic limitations, no schedule constraints — just professional education when and where you need it.
The curriculum covers everything from screen preparation and ink systems to production workflow and quality control. Built by people who have actually run production floors.
TDA is currently transitioning to new management. Updated leadership information will be published as the transition completes. The association remains fully operational during this period.
