  • Type size. The CDC recommends 16- to 18-point type or larger. CDC: font size
  • Contrast. The CDC recommends the highest contrast, and says black text on white is best. CDC: contrast Check the small contact details too, not just the main warning.
  • Paper. The CDC says to avoid glossy paper because it can cause glare. CDC: paper finish Ask to see the paper finish next to the print sample.
  • Words. The CDC recommends plain language and emphasizing the directions the reader must follow. CDC: plain language Have your safety reviewer keep the meaning while you check the layout.

Do a real-size check

Read the safety headings, the body copy and your contact details at actual print size, with no zooming. Ask a few of the people you mail where they would look first and what is hard to read.

Write down the changes people ask for before you approve. If the current format cannot meet a reader's need, ask which other formats are available. Have the revised safety piece reviewed.

Does asking for readable print get us a large-print option?

No. Ask the mailing team which formats are available. Put your need in the quote request and ask for a sample before you agree. Approve the piece you will actually send.
