How to Disallow Lower Resolution Files in the Build A Gangsheet App

This guide will show you how to prevent customers from uploading low-resolution files to the Build A Gang Sheet App on your Shopify store. Enforcing a minimum resolution helps maintain print quality and reduces the risk of blurry or pixelated outputs.

Step-by-Step: Enforcing a Minimum Image Resolution

  1. Open the Build A Gang Sheet app from your Shopify admin dashboard.
  2. Select the Builder Settings section to manage design input preferences.
  3. Turn on the toggle labeled Disallow Lower Resolution to enable file filtering based on resolution quality.
  4. Enter your preferred Minimum Resolution (e.g., 3000 x 3000 pixels) to define the threshold for acceptable uploads.
  5. Click Save to apply your settings.
Pro tip

Choose a resolution that aligns with your production needs. Higher minimums ensure sharper prints, but balance it with ease-of-use to avoid excluding users with moderate-quality files.
