Step-by-step explanation:
The file format that is central to a prepress workflow solution is PDF (Portable Document Format). PDF files are widely used in the prepress industry because they preserve the original formatting of a document, including images, fonts, and layout, regardless of the software or platform used to create the document. This makes it easier to share and print documents, ensuring consistency across different devices and operating systems. Additionally, PDF files can be compressed to reduce file size without losing quality, which is crucial when dealing with large files in a prepress workflow. This format also supports interactive elements such as hyperlinks and form fields, allowing for more versatile and dynamic documents.
