What file formats are best for printing (rasterized vs. vector fonts)?

For the sharpest printed text, use non-rasterized (vector) fonts rather than fonts flattened into an image. Vector type stays crisp at any size on press, while rasterized text can soften or pixelate, especially at small sizes.

• Keep type as live or outlined vector text inside a PDF.
• Outline or embed fonts so nothing substitutes during processing.
• Avoid very thin strokes for small text, since fine lines can weaken or drop out.
• Use a readable weight so letters hold their shape in print.

Vector fonts in a print-quality PDF give the cleanest, most legible result on the finished product.
