Print-Ready Files tutorials

A print-ready file meets the resolution, bleed, color, and font requirements a printer needs to produce an accurate result — get any of these wrong and a job can be rejected, reprinted, or shipped with visible defects. These tutorials cover checking DPI, bleed, safe area, color mode, and font handling before a file goes to production, including how Printcart’s AI preflight tool catches common risks early. Use this category if you accept customer-uploaded artwork or want to standardize file checks across a catalog.
