What does it mean to outline fonts?

Why printers ask for it

Live text in a design file does not contain the letters. It contains the characters, plus the name of a font, and the machine that opens the file is expected to have that font installed. If it does not, the software quietly puts something else in its place.

That is the whole reason, and print shops' own help pages say so in almost identical words: when the designer's typeface is not on the press operator's computer, a different one is substituted, which throws away the work that went into choosing it and shifts how the text sits. A headline set in a narrow face comes back in a wider one, a line that fitted now wraps, and the spacing between letters is no longer the spacing that was approved. One print shop's page adds the practical cost: the job stops while someone asks you for a corrected file, which is the part that turns a small problem into a missed deadline.

Outlining removes the dependency. Once the letters are shapes, there is no font to be missing, so there is nothing to substitute. In Illustrator the command is Type → Create Outlines; other drawing programs call it converting text to paths or curves. It is desktop work, and it is usually a ten-second job for whoever drew the artwork.

What actually breaks if you skip it

Sometimes nothing at all, which is why the advice you find online disagrees with itself. The failure needs two things to line up: live text in the file, and no copy of the font available where it is opened. Remove either half and the file prints as drawn.

When it does go wrong, it goes wrong quietly. Nobody gets an error. The file opens, the layout looks plausible, and the only person who notices the wordmark is in the wrong typeface is the one who knows what it should look like — often after the run. The same thing is easy to see on the web, where a logo asking for a font the viewer does not have falls back to whatever is around: obviously off to its designer, unremarkable to everyone else.

Outlining or embedding: printers often prefer the second

There is a second way to kill the same problem. A PDF can carry the fonts it uses inside itself — embedding, which writes the font (or just the characters the file needs) into the PDF. Nothing is then looked up on the opening machine, so nothing can be substituted, and the text stays text.

Several print-industry sources make the point that a PDF with its fonts properly embedded prints correctly without outlining anything, and at least one printer says it accepts outlined files but would rather have embedded fonts, because it can still fix a typo if one turns up. A long-running argument in the prepress world goes further and says you should almost never need to outline at all.

There is a licensing wrinkle underneath it: some font licences restrict embedding, and some are said to forbid outlining, which is a question for whoever bought the font rather than for the printer. The practical upshot is that the question to ask is not “should I outline?” but “do you want the text outlined, or are embedded fonts fine?” — one of the few things worth putting in the email with the file.

What outlining costs you

• The text is no longer text. It cannot be edited, re-set, spell-checked or searched. A typo found after outlining has to be fixed in the version that still has live text — which is why every source that recommends outlining also says to save a duplicate first and keep the editable master.
• Very small type can suffer. A common prepress caution is not to outline text below roughly 10 point, because a font carries hinting — instructions for rendering cleanly at small sizes — and shapes do not. The argument against routine outlining rests partly on this: it can cost a little typographic quality for no gain.
• The file gets heavier. Every letter stops being a character plus a font reference and becomes its own set of curves. For a logo that is neither here nor there; for pages of body copy it is not nothing.

How to tell whether a file's fonts are outlined

There is no single clean test, which surprises people. The closest thing, on a desktop, is to open the PDF in Acrobat or Adobe Reader and look at File → Properties → Fonts. Each font listed should say Embedded or Embedded Subset. An empty list suggests the text was outlined — but as the Adobe forums put it, that is an assumption rather than a test: a file with no text in it also lists no fonts.

The other quick check is to try to select the text. Live text gives you a text cursor and lets you drag a selection across a word; outlined letters are shapes and give you nothing. Note that the two checks answer different questions. The Fonts tab tells you whether fonts are embedded; a subset-embedded font is still live text, which may be exactly what your printer is happy with.

What a phone can and cannot tell you

If the file arrived in a chat or an email and there is no desktop in reach, the honest answer is: a phone can show you the artwork, and it cannot outline anything. Pathside is a viewer — it opens .ai, .pdf, .svg and .svgz on the device, and an .eps when that file carries a PDF inside it, deciding what a file is from its first bytes rather than its name. It does not change files, so converting text to outlines is not something it or any other viewer can do for you.

It also cannot run the select-the-text check: it draws each page as artwork, so there is no text cursor to try. What it is good for is the thing a printer is actually warning you about — seeing whether the type looks like the type you approved.

That shows up most plainly in an SVG, because an SVG's live text names a font and the renderer looks it up on the device doing the drawing. Pathside hands its SVG renderer no fonts of its own: AndroidSVG resolves a font-family only through a resolver the app supplies, and the library's own default answers that the reference could not be found. So an SVG that expects the designer's font is drawn with a stand-in instead, and the odd spacing you see on the phone is the substitution a printer means when they ask for outlines. Which stand-in you get depends on the device, so treat it as a signal, not a proof. Opening an SVG on Android covers the other two reasons one can look wrong.

A PDF, or the PDF that is hiding inside most .ai files, usually carries its fonts with it — which is why those tend to look the same everywhere, and why looking right on your phone is not evidence that anything was outlined. Opening, zooming and stepping through artboards are free in Pathside; exporting is a one-time unlock, which gets you a PNG or JPG at 1024, 2048 or 4096 pixels on the long edge, or a one-page PDF, one page at a time. Nothing you open is sent anywhere, and it all works in aeroplane mode.

What to ask for, in one message

If a printer has asked you to outline the fonts and you are not the person who drew the file, forward exactly that, and add the second half of the question: “are the fonts embedded in the PDF, or do you need them outlined?” Ask for a copy with outlines if the printer wants one, and ask the designer to keep the editable master so a typo is still cheap to fix.

And before any of it goes out, look at the file. Checking a logo before it goes to print runs through the five things that go wrong between approval and the press, including the one a phone screen genuinely cannot judge, which is colour. PNG or PDF for a logo covers which file to attach once the text question is settled.
