Why Type 3 Fonts Can Cause Printing Issues

For reliable, high-quality printing, we do not accept files that contain Type 3 fonts. While a file may appear correct on screen, Type 3 fonts can cause unexpected print and processing issues that make the file unsuitable for professional production.

What Are Type 3 Fonts?

Type 3 fonts are an older, outdated font format. Unlike modern font types, they do not follow consistent rendering rules across different software, printers, and workflows.

They are considered unreliable for professional printing and can lead to unpredictable results.

Why Are Type 3 Fonts a Problem?

• Unreliable Output – Type 3 fonts don’t follow consistent rendering rules. This means text may look one way on screen but print very differently, or not at all.
• No Hinting or Smoothing – Type 3 fonts don’t support modern font technologies like hinting. This can make edges jagged, blurry, or uneven, especially at small sizes.
• Limited Support in RIPs & Printers – Many print workflows, especially professional RIP software, cannot process Type 3 fonts correctly. This can cause missing text, incorrect characters, or even job failures.
• Better Alternatives Exist – Most professional design applications automatically embed or convert fonts to safer formats (like Type 1, TrueType, or OpenType). These formats are universally supported and ensure your design prints as intended.

How to Avoid Type 3 Fonts

Most modern design programs offer export settings that prevent Type 3 fonts from being included in your file.

To help avoid issues:

• Export PDFs using reliable print settings such as PDF/X-1a in Illustrator
• If needed, convert text to outlines before exporting
• In Canva, select Flatten PDF during export
• Use modern font formats whenever possible
