Does changing an image to 300 DPI make it sharper?
No. A 300 DPI label alone does not create more image detail. For image files, effective PPI means pixels per printed inch. A 3,000-pixel edge prints at 10 inches (25.4 cm) at 300 PPI. Enlarging the pixel dimensions is a separate step, and important text still needs visual checking.

Before you send it to the print shop
This is an initial size and resolution check—not printer approval. Material, colour profile, bleed and the printer’s own template still need confirmation.
Example pixel counts exclude bleed. Your print shop’s template takes precedence.
