Exporting Print PDF Documents (InDesign)
- If you don't have links or multimedia and you want better quality or more options, export as Print
- Set Adobe PDF Preset to High Quality Print and Standard to PDF/X-1a:2001 (ISO standard for graphic content exchange, only choose this for CMYK documents)
- Set Compatibility to minimum PDF Version Acrobat 6 (PDF 1.5)
- Under Viewing select Layout Single Page / Single Page Continuous
- Under Options check the Optimize for Fast Web View
In the Compression tab you can control how high a quality pictures you want. Around 72-100ppi is web standard, where 300ppi is for print. The larger image sizes, the larger the PDF file.
- For extreme image quality set Bicubic Downsampling to 300 ppi for images above 450ppi. Compression None. Use at the risk of having way too big files which Napp® will have a hard time digesting.
- For very good image quality set Bicubic Downsampling to 200 ppi for images above 300 ppi. Compression Automatic, Image Quality Maximum.
- For smaller PDF file but lower image quality set Bicubic Downsampling to 100ppi for images about 150ppi. Compression Automatic, Image Quality Medium.
- Under the Marks and Bleed tab, make sure All Printer's Marks and Use Document Bleed settings are unchecked (unless you want to upload a Print file)
- Under the Output tab set color conversion to your desired color profile in Destination, typically Coated FOGRA39 or ISO Coated v2 300% for CMYK
- If you're creating a PDF for web-use you need an RGB color profile - in the top right under Adobe PDF Preset change the Standard from PDF/X to None. Now, in Destination you can select an RGB color profile such as sRGB IEC61966-2.1 or Adobe RGB.
- In the Advanced tab set Subset fonts when percent of characters used is less than 100%
- Use Acrobat Pro Preflight functionality to validate your PDF (it finds overdraw issues, font issues and PDF syntax issues)
That’s all - now your PDF documents are ready to be published.
