POD Product Mockup and Upload Workflow

I need a repeatable workflow for creating and uploading new print-on-demand products to my Shopify store. Here are my details:

Store name: [YOUR STORE NAME]
POD supplier: [e.g., Printful, Printify, Gelato]
Design file format: [e.g., PNG at 300dpi, AI, PDF]
Design dimensions: [e.g., 4500 x 5400px for a t-shirt front]
Product types I am launching: [LIST PRODUCT TYPES]
Mockup style preference: [e.g., lifestyle photos, flat lay, ghost mannequin, digital renders]

Please help me build this workflow:


  Design preparation checklist: what file specifications, resolution requirements, color mode (CMYK vs RGB), safe zone margins, and bleed settings I need before uploading any design.
  Step-by-step process for uploading a design to [SUPPLIER] and generating product mockups, including how to generate multiple mockup angles and color variants.
  Mockup selection strategy: which mockup types convert best for each product category, for example lifestyle photos for apparel, flat lays for accessories, and room scenes for home decor.
  How to export finalized mockup images in the correct dimensions and file format for Shopify product listings.
  Shopify product creation workflow: how to create the product, set up variants (size, color), upload mockup images, write alt text for each image, and assign the correct product type and collections.
  Naming convention for products, SKUs, and design files so my catalog stays organized as it grows.
  How to bulk-create multiple color variants of the same design efficiently.
  A quality check step before publishing: verify print placement, check mockup image quality, confirm pricing is correct, and preview the product page as a customer would see it.
  Process for updating an existing product with a new design revision without losing reviews or SEO ranking.
  A content calendar template for planning and scheduling new POD product launches.
