How to Use This Print Hub

First, identify the final destination format and ratio. Next, set your canvas to that ratio before adding detailed layout work. This avoids late-stage distortion, margin drift, and unnecessary reflow.

In mixed workflows across print and digital channels, keep a master source and export one ratio-specific asset per destination. This preserves consistency across paper, social cover assets, and marketplace submissions.
