Guidance on Optimizing T-Shirt Designs for Clear Printing

I am seeking an experienced freelancer to help me optimize my existing designs created in Adobe and Canva for clear printing on t-shirts. The goal is to gain a thorough understanding of the process so I can handle it independently in the future. This includes reviewing my current designs, identifying issues, and providing step-by-step guidance to ensure clarity and quality. The project should be completed within 2–3 days.
