Problem 3: Missing Bleed
Problem 4: RGB vs CMYK Color Mode
Avoid very bright, saturated colors in your Canva design
Test your design in Canva's "Print Preview" mode
Adjust colors to be slightly less saturated than looks good on screen
True CMYK conversion requires a professional tool like Adobe Illustrator or InDesign
Problem 5: Missing Crop Marks and Trim Lines
In Canva, enable "Crop marks and bleed" in the PDF print export settings
Verify the crop marks are at the correct trim line position, not at the bleed edge
