|PDF File Requirements|
|Why has the the conference adopted these requirements?||
IFAC-PapersOnline archives papers presented at IFAC events.
The proceedings of events up to 2008 are presented as bitmapped images scanned from print.
For all later events distilled PDF has been selected as the required format because it presents significant quality improvements over scanned PDF. Font display is sharper, charts and photos can be shown in their original colors, and distilled PDF documents can be searched using Adobe Acrobat's built-in text-finding feature.
To ensure that these pdf files may be viewed and printed with a consistent quality by all users on different platforms using different viewers a number of compliance requirements are imposed.
|What are these compliance requirements that my document must meet?||
The following characteristics are required for pdf compliance:
|How do I verify if my PDF meets these requirements?||
You can check if your document meets most of the requirements by opening
these windows in Adobe Acrobat Reader:
File | Document Properties | Summary File | Document Properties | Fonts File | Document SecurityUnfortunately, you cannot determine information about image resolution. The person preparing the document must ensure that the images comply with the requirements.
For your convenience, PaperPlaza has implemented tests for fonts and security. You can test whether your file meets PDF version number compatibility, fonts and security requirements by uploading the file through the Test your pdf document link.
|Why are Type 3 fonts not acceptable?||
Bitmapped fonts are created for specific devices.
Hence fonts created for print (at, say, 300 dpi) do not render well on screen and those created for screen do not print properly.
See the example below:
The image to the left was created for printing at 300dpi on a laser printer using bitmapped fonts (Type 3), while the one on the right was created using scalable/vector fonts (Type 1). Vector fonts scale to the resolution of the device and hence appear crisp on screen as well as in print.

Unfortunately, if your manuscript does not pass the PDF version number compatibility, fonts and security requirements then
you will not be able to upload it.
