Running the test
Top |
To test your pdf file, follow these steps:
|
Viewing and understanding the test results Top |
At the top of the test results page you will see this information
The various pdf issues are described below |
File size | Files larger than the set limit are not accepted for upload |
Page count | Documents whose page count exceeds the set limit are not accepted for upload |
Character count | If a limit is set to the character count then documents whose count exceeds the limit are not accepted for upload |
Pdf version compatibility | If your pdf file uses very recent pdf features then users with older pdf viewers may not be able to view and print your file properly. Make sure that you configure the application that you use to produce your pdf file so that your pdf is compatible with the journal requirement |
Lowest acceptable pdf version | Some journals do not accept early pdf versions. Please use the most recent compatible pdf version |
Paper size | Most journals require the paper size of your submission to be either A4 or US Letter. Each page is individually tested for paper size |
Page margins Top |
Some journals that publish preview versions of accepted
papers on the web impose requirements on the page margins of the final
version of the pdf document for uniform appearance. The pdf test checks the margins by determining if the prescribed margins are blank, with a certain tolerance. If there are margin impositions you will see a report such as
Margin impositions: Page numbers inserted into the bottom or top margin are a frequent cause of margin errors. |
Searchability Top |
Most pdf documents are fully searchable. This is a
valuable asset because it greatly improves the accessibility of a
document, especially if it belongs to a large collection of documents.
It is in your interest as author that your document is searchable Some pdf documents cannot be searched. An obvious example is a pdf document that has been scanned from a paper document. Some other pdf documents are not searchable because of nonstandard encoding of the document text The pdf test of the journal system checks for searchability by extracting the document text from the file and testing it for the occurrence of the common English words 'the', 'of', 'and', 'to', 'in', 'that' and 'is'. If there are a sufficient number of occurrences then the document is assumed to be searchable. If there are few or no occurrences then the document is marked as possibly being nonsearchable. It nevertheless may be searchable by Adobe Acrobat, Adobe Reader and other pdf reader applications even though encoding is nonstandard If your file is reported as "This document may not be searchable" then please open it in Acrobat, Adobe Reader or another pdf reader that supports searching, and check manually if the file is searchable. If it is, accept our apologies for the false alarm and upload the file If you find your file to be nonsearchable then if you upload the file and searchability is a journal requirement then the file may be returned to you for reformatting. In this case we recommend using a recent version of up-to-date software to convert your source document to pdf as described in the support section |
Font embedding Top |
Every pdf document with text uses fonts. The pdf format
allows to embed fonts within the pdf document. If a font is embedded
then the viewer can display and print any text based on this font
correctly. If a font is not embedded then the viewer looks for a
substitute font on the computer where it is installed that is similar to
the original font and uses this. The similarity may not be complete. For
this reason publishers of pdf documents that are to be published and
distributed electronically often require that all fonts are embedded An exception is sometimes made for certain widely available fonts referred to as 'Base fonts'. Even if these fonts are not available on a computer then they may often safely be substituted by similar other fonts The pdf test detects all fonts used by the document. Non-embedded fonts that need to be embedded are reported. The report includes the pages on which the fonts are used Consult the support section on how to make sure that the required fonts are embedded |
Font
subsetting Top |
When a font is embedded within the pdf document pdf
supports the option to embed only those characters from the font that
are actually used in the document. This is called font subsetting. It
reduces the size of the pdf file. Some publishers require all embedded
fonts to be subset The pdf test detects all fonts that are non-subset embedded. Consult the Support section on how to make sure that embedded fonts are subset |
Type 3 fonts Top |
Type 3 fonts are based on a sampled image
representation and not on a vector representation like other fonts. They
are not scalable and do not always view and print well. Their use is not
recommended for high-quality documents and this is why Type 3 fonts are
sometimes not accepted The pdf test detects all fonts used by the document. If Type 3 fonts are not allowed and any are detected then they are reported Consult the support section on how to avoid the use of Type 3 fonts |
Oriental fonts | If a pdf document uses Chinese, Japanese or Korean
fonts then oriental language support may be required to read or print
the document. To make the document accessible to the widest possible
audience the use of oriental fonts in an English language document
should be avoided Consult the support section on how to avoid the use of oriental fonts in an English language document |
Encryption | If some or all privileges for opening and editing a pdf document have been password protected then parts of the document are encrypted. The pdf test does not support encryption and encrypted documents are usually not accepted |
