Pre-print PDF and its role before printing

With the rapid development of computer technology and network communication technology, the printing and publishing industry has undergone earth-shaking changes, and the traditional printing process has been greatly affected. PDF (Portable File Format) has become an electronic file popular in recent years. Format, you can use Adobe Acrobat Reader to view, browse and print PDF files. Adobe Acrobat 6.0 and PDF 1.5 are a technological advancement over Adobe Acrobat 4.0 and PDF 1.3, respectively, introduced in 1990. Today, PDF has become an irreplaceable file format for prepress and high-quality printing.

First, what is the pre-print PDF?

Preflighting PDFs For Print Preflighting PDFs For Print uses the English word Preflighting. Preflighting is used in the printing industry to mean preflighting 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, only 23% to 30% of all documents currently prepared for printing in the United States use Adobe's PDF format. 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.

Acrobat 6.0 Professional, together with various PDF plug-ins and applications, now allows us to build a good workflow for accurately generating, preflighting, and editing PDF documents. When linking good upstream and downstream prepress practices, PDF documents can be successfully optimized to achieve high-quality printing results.
