After many PDF files are printed, there are often cases where the content is welted or even cut. This is because the margins of PDF are too small and there is almost no blank space. Therefore, we need to increase the margins of the PDF before printing the PDF. Here are three ways to make PDF margins bigger: HeSoft Doc Batch Tool Adobe Acrobat DC, WidenPDF. There is a need to try to operate quickly!
Why make PDF margins bigger
1. Many PDFs are just the right size on the screen, but after printing, there are often problems of edge text being cropped and table lines missing. This is because the printer has non-printable areas, which can occur if the margins are small. Therefore, before printing a PDF, you must expand the margins of the PDF to leave a safe area for the printer.
2. If the margins of the PDF are too small, the text content is close to the edge, which not only affects the reading experience, but also looks very poor in typesetting. After the PDF margin becomes larger, it can reduce the visual pressure, improve the reading comfort, and improve the professionalism and aesthetics of the document, making the PDF more like an official document.
3. If the PDF file needs to be processed twice in the later stage, such as cropping again, or adding watermarks, annotations, page numbers, etc., the margins of the PDF will be expanded to leave more space for operation without affecting the body content.
