The PDF file must be a certain version.I’ve simplified their recommendations here and there to keep the overview from getting too long. This is, as far as I know, the only international standard that describes the requirements of print-ready PDF files. The overview is inspired by the GWG 2015 specifications. Below is a general description of what should be checked and why it is checked, including the reason why each check is done. This means that it is impossible to provide one single set of rules that apply to every possible type of job or printing. The things that need to be checked in a file depend on its intended usage. What needs to be checked during preflight? The receiver of such a file only needs to verify if this ‘seal’ is present. Essentially both systems allow a preflight application to embed metadata in a checked PDF to document how the file has been checked. These are Enfocus ‘Certified PDF’ and the Ghent Workgroup ‘Universal Proof of Preflight’. It is worthwhile to know that there are two technologies available to ensure that files only need to be preflighted once. Printers or service bureaus should always preflight incoming data, simply to make sure that the quality of the product that they will deliver meets the customer’s demands. This implies that designers should preflight their creations before sending them to their agency or printer. The earlier in a process that problems are detected, the easier and cheaper it is to fix them. This way you are certain that the preflight system can correctly handle general market requirements. It is a good idea to use a solution that has been certified by GWG and appears in their application list. Which engine you choose depends on the level of automation that is needed, the different types of files that the engine needs to be able to handle, the platform on which the application should run (Mac, PC,…) and the available budget. It is either a module which was licensed elsewhere or the vendor’s own development. Many prepress workflow systems, such as Agfa Apogee Prepress or Kodak Prinergy, include a preflight engine.Others like Markzware FlightCheck can handle a wider range of file formats. Some like Enfocus PitStop Server focus specifically on checking PDF files.
There are also stand-alone preflight applications on the market.The best-known ones are Enfocus PitStop and callas pdfToolbox. There are several preflight plug-ins for Acrobat.
#PDF TOOLBOX VS PITSTOP PRO#
With each new release, this option has been improved and it is actually pretty powerful in Acrobat Pro CC.
#PDF TOOLBOX VS PITSTOP PROFESSIONAL#
From version 6 onwards Adobe Acrobat Professional includes a preflight engine.There are a number of preflight solutions on the market. Enfocus published a nice PDF about the 10 reasons to preflight files. If you look at the list of the 10 most common problems with PDF files, half of them can easily be avoided by preflighting all files. Why preflight PDF files?Ĭhecking files is essentially done to avoid problems in processing or printing content. In case you wonder: the term preflight was derived from the long list of checks that pilots have to complete before taking off with an airplane. who should do the check and when it should be done.the tools that are available to check page content.To make sure that a file matches the requirements to reproduce its correctly, it needs to be checked or ‘preflighted’. Using PDF is, however, no guarantee that the receiver of a file can actually output it as intended. The PDF file format is a solid standard to exchange pages, ranging from single ads to complete publications.
Nowadays PDF files are sent to printing companies. Preflighting is the process of checking if the digital data required to print a job are all present and valid.
