Getting Started with PrntFlow
PrntFlow is a Shopify app for POD t-shirt stores that automates mockup uploads and variant assignment using your own mockup images.
What PrntFlow Does (and Doesn't Do)
PrntFlow is an embedded Shopify app designed specifically for POD t-shirt stores. It automates the process of generating composite mockups and assigning them to color variants in your Shopify product catalog. You bring your own winning mockup style, and PrntFlow handles turning it into variant-specific product images.
PrntFlow Does NOT:
- Provide stock mockups or mockup libraries
- Generate mockup images from scratch or create AI mockups
- Run Meta ads, manage ad campaigns, or optimize ad creative
Prerequisites
Before installing PrntFlow, make sure you have:
- A Shopify store with t-shirt products that have color variants. PrntFlow is designed for products with options like "Color: Black, White, Red, Yam" and works with products synced from POD platforms like Printify, Printful, Gelato, or Monster Digital.
- At least one "winning" mockup style. You need your own base mockup images per color (for example, a black t-shirt mockup, white t-shirt mockup, etc.) from whatever design tool or service you use.
- Permission to install apps and approve billing in Shopify. You'll need Shopify admin access to authorize PrntFlow and approve the monthly subscription charge.
Install & Authorize
Installation happens through the Shopify App Store. Once PrntFlow is live on the App Store, you'll install it like any other Shopify app. During setup, you'll be prompted to authorize PrntFlow to access:
Products & Variants (Read-Only)
PrntFlow reads your t-shirt products and their color variants to build templates and select products for mockup generation.
Product Media (Read/Write)
PrntFlow uploads generated mockup images to your Shopify product media and assigns them to variants.
What PrntFlow Does NOT Access: PrntFlow does not access orders, customers, or payment details. All billing is handled through Shopify's app billing system.
Your First Visit: The Dashboard
When you open PrntFlow from your Shopify admin for the first time, you'll land on the Dashboard. This is your command center for tracking mockup templates and product coverage.
The Dashboard Shows:
- Template count – How many mockup templates you've created (0 on a fresh install)
- Total products – The number of t-shirt products synced from Shopify
- Products with mockups – Products that have been processed through PrntFlow
- Products without mockups – Products that still need mockup generation
Getting Started Guide
For new installs, the Dashboard includes a Getting Started card with quick steps:
- • Create product templates and assign your available colors
- • Upload base mockups that represent each product color
- • Upload a test t-shirt graphic to tweak default location
- • Test your template by publishing to a draft product
You can return to the Dashboard anytime by clicking "Home" in the app navigation.
Core Workflow Overview
PrntFlow's workflow is organized around three main areas in the app navigation. Each serves a specific purpose in the template creation and mockup upload process.
Create New Template
A guided wizard that walks you through creating a reusable mockup template. You'll name the template, pick a Shopify t-shirt product, upload base mockup images for each color variant, optionally group colors into light and dark shirts, upload a test graphic, and set the default placement and scale. Once saved, this template can be applied to any product with matching colors.
Manage Templates
A list of all your saved templates. From here, you can set a default template (which will be pre-selected when you upload mockups to products) and delete templates you no longer need. This is your template library—your collection of winning mockup styles ready to be reused across products and designs.
Upload Product Mockups
The main workflow for applying templates to products with real designs. Select a product from your Shopify catalog, pick a template (your default template is pre-selected to save time), upload your design graphic(s) for the product, and click to generate. PrntFlow composites your design onto each color's base mockup, uploads the generated images to Shopify, and assigns the correct mockup to each color variant automatically.
