The Preflighting PDFs ForPrint (preflightingPDFsForPrint) uses the English Preflighting term to refer to the pre-inspection work performed prior to the takeoff of the aircraft to ensure the safety of the aircraft's flight. Preflighting is used in the printing industry, which means preflight work before printing. Pre-screening before printing is undoubtedly crucial to the entire printing process.
As the printing industry continues to adopt new technologies, not only the color desktop publishing system (DTP) and the computer-to-plate system (CTP), but also a variety of new process flows are emerging. In the face of a large number of new technologies, many experts in the electronic publishing industry predict that the final printer will only need to accept PDF files. Therefore, in the pre-screening work before printing, the pre-printing PDF is predominantly emphasized. However, according to estimates by the US Printing Technology Foundation (GATF) and the Seybold magazine, only 23% to 30% of all documents currently prepared for printing in the United States use Adobe's PDF format. Over time, this number will continue to rise. The use of PDF file format in China is a matter of recent years, and it is mostly used for network transmission. It is mainly used for the transmission of office documents, online e-books, etc. The use of PDF in the printing industry is relatively small.
Second, why use pre-printing PDF before printing?
Since the PDF generator and receiver are independent of the operating system platform in the print production process, the PDF file format retains all the information of the original file such as characters, fonts, layouts, colors, etc. At the same time it uses industry-standard compression algorithms to make files The capacity is small, it is easy to store and transmit quickly, and it has the function of soft proofing. It is easy to pre-check, and the file browsing is not limited by the operating system, network environment, and application version. Therefore, the PDF file format will quickly be applied to various fields. However, in the printing industry, there are still many imperfections in the generation of PDF for printing, and sometimes the receiver receives the customer's PDF. The most common problems with the customer's PDF file are the font is not embedded, the resolution is too low, there is no bleeding, and the color space used by the user is not right. In order to ensure that the whole process of prepress and printing can proceed smoothly, PDF as an inherent file format, it is necessary to conduct pre-inspection.
