If the fonts aren't installed, Acrobat uses the font descriptions to create substitute fonts that resemble the original fonts. Acrobat Distiller 7. A font that is embedded in a PDF file is always available for viewing and printing, whether or not it's installed on the system. However, you cannot edit text in the PDF file unless the font is installed. If you try to edit text that uses an embedded font and the font isn't installed, Acrobat returns a warning and uses a substitute font instead.
Acrobat Distiller acknowledges and preserves the original font permissions, even if a PDF file is redistilled. Fonts that have restricted permissions can't be embedded and will cause Acrobat Distiller to return an error during the conversion process. Similarly, fonts that don't use a character encoding format, such as WinAnsi or MacRoman, may cause Acrobat Distiller to return an error if you try to embed them. If Acrobat Distiller can't interpret or find the font information it needs from a font, it substitutes the font.
In rare instances, Acrobat Distiller converts such fonts to bitmap images, which prevents the font from being searched, scaled, or edited. Acrobat Distiller embeds a font descriptor that is, font information for each font that it embeds.
A descriptor can include the following information:. The type of font you use can affect how text in your PDF files appears and prints, and whether or not the text is searchable and editable. If a PDF file contains fonts that have been converted to bitmap images, the viewers won't process the images as fonts, but will instead display and print the images just like any other bitmap images.
Text converted to bitmaps, however, isn't searchable or editable. These fonts are native to the Mac OS X system and are identical to standard font suitcase files except that the font resources are stored in the data fork of the file. For English-language versions of Acrobat Distiller, you must install the appropriate font support package. Acrobat automatically displays Asian fonts that are embedded in a PDF file.
If Asian fonts aren't embedded, Acrobat can display them after you install the appropriate font support package. Because multiple master fonts such as Minion MM create specific instances of a font based on the properties of a document and where the font is used, Acrobat Distiller cannot embed them. Instead, Acrobat Distiller adds a subset of the font, which has a unique font ID.
Because MM fonts generate these instances dynamically, you cannot embed the fonts or edit them in Acrobat. Adobe Technical Support recommends that you don't use MM fonts if you need to edit or embed fonts in Acrobat. OpenType format is based on Type 1 and combine outline, metric, and bitmap data into a single font file. OpenType format includes advanced typography features that most applications have not yet taken advantage of; as a result, these applications recognize and treat OpenType format as TrueType fonts.
Because each symbol font contains unique characters and character sets, Acrobat Distiller always embed these fonts to prevent them from being substituted. If the font doesn't include these permissions, Acrobat Distiller embeds a font subset that is, only the characters of the font that are used in the document. Note: Acrobat Distiller doesn't report subsets of TrueType fonts in its log file. And even though the TouchUp Text tool in Acrobat lists the fonts as embedded in the Text Attributes dialog box, you cannot edit a font subset with this tool because the system can't recognize the font subset's unique font ID and map it to the original TrueType font on the system.
If you edit a font subset with the TouchUp Text Tool, Acrobat substitutes the font with a sans serif or serif equivalent.
When you use Acrobat Distiller to create PDF files, text formatted with TrueType fonts may not be searchable, depending on how the font information was written into the PostScript file. In these cases, PostScript printers convert the TrueType font as a Type 42 font, which best preserves the font's characteristics, such as searchability. A Type 42 font is usually generated by a printer driver to download TrueType fonts to a PostScript printer that includes a TrueType rasterizer.
By this method the TrueType font is interpreted directly by Acrobat Distiller, which provides the most accurate description of the original TrueType font. Variables that can affect this font information include: the application that created the PostScript file, the font itself, the PostScript printer driver, and the PostScript Printer Description PPD file. Information is written into a PostScript file either by the application that generates PostScript code or by the PostScript printer driver.
For both appearance and searchability, Type 1 fonts offer reliable conversion to PDF. Because Type 1 fonts don't need to be converted to another format when the font or a subset of the font is embedded in a PostScript file, they offer the best results when you use Acrobat Distiller. The font size is within an appropriate range this is, the CharStrings dict leng value is greater than but less than You can check the CharStrings dict leng value in a font editing application.
Because Type 3 fonts use the entire PostScript computer language to express a font, they can include specifications that Type 1 fonts cannot, such as shading, color, and fill. However, Type 3 fonts aren't optimized for size or performance, so characters may appear bolder than their Type 1 counterparts.
Acrobat and Adobe Reader convert the Type 3 characters to bitmap images and then display them. When you print to a PostScript printer, Acrobat and Adobe Reader use your PostScript printer driver to download the font to the printer. You can find the conversion settings in the preferences of Acrobat. I see. Is it possible to set a preset on a case by case basis, for each file that I want to create a PDF from, in Acrobat?
Distiller is not a universal converter. It is used to convert some file types, and not others. It is used for some conversion methods, and not others. What file type do you convert, and what do you click to do the conversion? What's important to me is to be able to select the Preset I want to use. I can do that easily in Distiller as described. In Acrobat, it's not as clear Bernd gave me some pointers.
These settings are designed to balance file size with quality, depending on how the PDF are used. You can also create and share custom presets for your unique output requirements. A saved PDF preset file has the suffix. I am converting eps. Then you must set up each file type. So you are in the right place. The page size for EPS files comes from Distiller settings. These usually contain a fixed page size. I assume the result will be the same if I convert in Distiller directly then.
EPS files do not have a page size, in the way PostScript files have a page size. It's absolutely forbidden [otherwise the EPS would set the size of the page where you placed it].
An EPS is not a page, it's a graphic even if it's the size of a full page. This is controlled by some cryptic options under Distiller's Advanced Job options. The last job option is "Resize page and center artwork for EPS files".
If on, the PDF is the graphic size. If off, the PDF default page size. I meant EPS dimensions here as "page size". This is all very helpful Test Screen Name, thank you. Is this information in the Adobe online documentation? If so, would you mind giving me a pointer? Registered: Jan 28 Posts: 3. We may have the same issue, although I am running Distiller 8.
The application I support uses Distiller to create PDFs outside of the limited directory access allowed in 8. It works fine with 8. I need to continue having the functionality to create PDFs where I want from within the application. It has a very limited set of methods and properties. I need to remove the directory access restriction placed on Distiller in 8.
