If you are using Adobe Distiller or a third-party application that generates PostScript files before converting them to PDF, you may need to explicitly tell the software how to handle CIDFontF1.
This involves mapping the dummy name to a real font.
Steps for Windows:
Note: This is a technical fix and usually requires administrator privileges.
To understand "CIDFontF1," we first need to understand the acronym CID. It stands for Character Identifier. In the early days of digital typography, standard fonts were limited. They were often restricted to 256 characters (single-byte encoding), which was sufficient for English but impossible for complex scripts like Chinese, Japanese, or Korean (CJK). cidfontf1 font new
Adobe developed the CID-keyed font format to solve this. A CID font acts as a container. Instead of a simple linear list of characters, it uses a mapping system (a CMap) to access thousands of glyphs stored in a large font file. This allowed for massive character sets needed for global languages.
Scenario: A Japanese bank sends monthly statements as PDFs. A developer tries to run OCR or text extraction but receives cidfontf1 font new missing errors.
Investigation: Using pdffonts statement.pdf:
name type encoding emb sub uni
------------------------------ ------------ ------------- --- --- ---
cidfontf1 font new CID Type 0 Identity-H yes yes no
Although the font is embedded (emb=yes, sub=yes), it has no Unicode mapping (uni=no). Therefore, text extraction fails. If you are using Adobe Distiller or a
Solution: Use pdf2htmlEX with a custom font remapping:
pdf2htmlEX --font-size-multiplier 1.2 --embed-css 1 --embed-font 1 --font-remap "cidfontf1 font new=NotoSansMonoCJKsc-Regular" statement.pdf
After remapping, the text becomes extractable and searchable.
Imagine you are a graphic designer prepping a book in Mandarin Chinese for a professional printer.
The term "F1" in this context is shorthand for Adobe Font Metrics (AFM) Format 1 or refers to the internal naming conventions within PostScript Type 1 fonts. Note: This is a technical fix and usually
Historically, CIDFonts were often bundled with F1 metrics (.afm files). While the CIDFont handled the raw glyph shapes (the "bodies"), the F1 file handled the spacing, kerning, and bounding box data (the "clothing").
In the 1990s and early 2000s, the combo was common:
When PostScript interpreters (like Adobe CPSI or Harlequin RIP) saw an F1 metric file linked to a CIDFont, they could render complex scripts accurately. However, this dual-system is largely legacy; modern workflows have merged these metrics directly into OpenType-CID fonts.
