To have high-quality prints, it is important to create and export PDFs using 300 DPI. In this guideline, you will be informed on how to save and export a PDF file in 300 DPI, the significance of DPI and ways to view its value on your PDF files.
How to Save a PDF at 300DPI
Inter alia, saving a pdf at 300 dpi entails the following:
Navigate through to Default Settings section within your creation tool for PDF.
Select Acrobat 3 so as to build a new PDF document.
Configure the general settings as instructed or shown in your software.
In case you are not sure whether or not this should be altered, just keep it at that since some projects may specify otherwise.
Exporting a .PDF with 300 dots per inch
To export your .pdf having 300 dots per inch (dpi):
Software that you use has ExportBitmapResolution being chosen.
Choose Change from Edit menu.
Decimal has to be entered in this DWORD value editing dialog.
Specify the resolution of 300 in Value Data text box.
Understanding DPI on PDFs
For instance, if your document might be printed into hardcopies of better quality HD printings then there should be sufficient resolution of say not less than three hundred D.P.I., but when you do not intend printing out these documents then seventy-two D.P.I. can do. Even though, three hundred D.P.I. remains as standard requirement for professional print work quality assurance purposes only.
Saving High-Resolutions .PDF
Thus, save yourself a high-resolution.pdf file by;
Select Save As under File menu and choose Adobe PDF format then click on Save button.
High-Quality Print is the preset Adobe-PDF option for choosing resolution setting. Printed color profiles are unnecessary; thus go Output pull down menus under Profile Inclusions Policy, select Do Not Include Profiles. Save
Checking DPI in a .PDF
Therefore, to check dpi of a PDF:
Open “Display Performance” under Edit>Preferences for Windows or InCopy>Preferences for Mac OS.
Which option you want to customize should be chosen from Adjust View Settings.
Use 72 DPI low resolution or view as gray area, to inspect the dpi setting in this image (generally 72 DPI for low-res pictures).
By following these steps, regardless of whether you are producing high quality prints or using digital versions, the right resolution will ever be set when saving and exporting your pdfs.
