Printing Terminology: PDF Files

By the early 1990s, computers had practically replaced all the traditional methods used to create documents for print. The two most dominant computer platforms then as now were Apple (Macintosh) and Microsoft (PCs) each utilizing proprietary operating systems. Hence, the graphics software used on each platform created files that could not be opened or viewed on the opposing operating system. Also, graphics software is and was by no means universal and created documents that could not be viewed or opened unless one had the exact same program running on the same platform. Fonts were another problem as the different platforms used different technologies to display and render type. Plus, with thousands of fonts available, it wasn’t possible to maintain complete font libraries for each platform. Pre-press departments at print shops and commercial printers had to have both Macintosh computers and PCs running the latest graphics software with massive font libraries to be able to open and view customers’ files.

Sometimes a file created on a PC could be opened on a Macintosh (or vice versa) provided the same software was used to create the document. However, there would often be unexpected changes or variations in the layout that required correction before going to print.

Thus, in 1993, the Adobe Corporation introduced the PDF (Portable Document Format) file format. This file format made it possible to share documents across platforms where they could be opened and viewed without needing the requisite software used to create the document. Plus, the documents would retain their layouts without major shifts or changes.

PDF Files (PDFs) are an industry standard.

Today, PDF is the preferred file format used to transmit documents for print. High resolution PDF files can be created and readily transmitted via the internet. Many printers enable customers to directly upload PDF files on their websites with automated software generating proofs and checking the PDF file for any potential issues before going press.
