# Fonts, Text & Strokes

> Font and text checks in a PDF preflight profile — embedding, subsetting, minimum sizes, stroke widths, outlining, and safe zones.

The **Fonts, Text & Strokes** section protects text integrity. Missing or unembedded fonts are the number-one preflight failure, because text that isn't carried in the file can't be guaranteed to print correctly. Each check lists its **action**, **settings**, and the messages the customer sees. See the [profile overview](/configuration/preflight) for how actions work.

## Fonts Embedded

Require all fonts to be fully embedded in the PDF.

| Field        | Detail                                                                                             |
| :----------- | :------------------------------------------------------------------------------------------------- |
| **Action**   | Reject                                                                                             |
| **Settings** | None                                                                                               |
| **Issue**    | Your file uses fonts that aren't included in it, so we can't guarantee your text prints correctly. |
| **Fix**      | Re-export your file with all fonts embedded, or convert your text to outlines.                     |

## Font Subsetting

Encourage smaller files by embedding only the characters actually used.

| Field        | Detail                                                                       |
| :----------- | :--------------------------------------------------------------------------- |
| **Action**   | Auto-fix                                                                     |
| **Settings** | None                                                                         |
| **Issue**    | Your file embeds full font files, which makes it larger than it needs to be. |
| **Fix**      | Re-export with font subsetting enabled.                                      |
| **Auto-fix** | We'll subset the fonts automatically before printing.                        |

## Minimum Font Size

The smallest font size allowed, to keep text readable in print.

| Field        | Detail                                                                                                                                  |
| :----------- | :-------------------------------------------------------------------------------------------------------------------------------------- |
| **Action**   | Warn                                                                                                                                    |
| **Settings** | Minimum (pt, default 5)                                                                                                                 |
| **Issue**    | Some texts are too small (`{actual.min_pt}` pt) and may not be readable when printed. The minimum for this product is `{target.pt}` pt. |
| **Fix**      | Increase the size of any important small text and re-upload.                                                                            |

## Minimum Stroke Width

The thinnest line width that will reliably reproduce on press.

| Field        | Detail                                                                                                     |
| :----------- | :--------------------------------------------------------------------------------------------------------- |
| **Action**   | Auto-fix                                                                                                   |
| **Settings** | Minimum (pt, default 0.25)                                                                                 |
| **Issue**    | Your file has very thin lines that may not print visibly. Lines should be at least `{target.pt}` pt thick. |
| **Fix**      | Increase thin lines to at least `{target.pt}` pt and re-export.                                            |
| **Auto-fix** | We'll thicken the hairline strokes automatically before printing.                                          |

## Allowed Font Types

Which font formats are permitted.

| Field        | Detail                                                                          |
| :----------- | :------------------------------------------------------------------------------ |
| **Action**   | Reject                                                                          |
| **Settings** | Disallowed formats (Type 1, Type 3, TrueType, OpenType, CID Type 0, CID Type 2) |
| **Issue**    | Your file uses a font format that isn't supported for printing.                 |
| **Fix**      | Convert your fonts to TrueType or OpenType and re-export.                       |

## Text Outlines Required

Require all text to be converted to outlines (curves) before printing.

| Field        | Detail                                                                      |
| :----------- | :-------------------------------------------------------------------------- |
| **Action**   | Auto-fix                                                                    |
| **Settings** | None                                                                        |
| **Issue**    | This product needs all text converted to outlines (curves) before printing. |
| **Fix**      | Convert all text to outlines (curves) and re-export.                        |
| **Auto-fix** | We'll convert your text to outlines automatically before printing.          |

## Text Safe Zone

The minimum distance live text must stay from the trim edge.

| Field        | Detail                                                                                                                           |
| :----------- | :------------------------------------------------------------------------------------------------------------------------------- |
| **Action**   | Reject                                                                                                                           |
| **Settings** | Safe zone (pt, default \~8.5 ≈ 3 mm)                                                                                             |
| **Issue**    | Some text is too close to the cut edge and may be trimmed off. Keep it at least `{target.safe_zone_pt}` pt inside the trim line. |
| **Fix**      | Move text further from the edges and re-upload.                                                                                  |
