3DAP (Digital Data Delivery for Australian Publications) is an industry group committee formed to ensure that advertising material prepared by different sources for use in publication printing can be faithfully reproduced together on the same press sheet. It also plays an important part in ensuring that the same material inserted in multiple publications will turn out consistent.
To make sure your PDF file conforms to the 3DAP standards:
- Open your source file in InDesign (if you're not using Adobe InDesign, you can reproduce the following steps approximately in the program you are using, although we recommend InDesign as best practice).
- Export the file. In the export window, under Output, ensure that the Color Conversion dropdown is set to Convert to Destination.
- Select PDF/X-1a:2001 as the standard.
- Under Output Intent Profile Name, select the correct 3DAP ICC profile.
Once you export your PDF it should conform to the ICC profile you have selected.
If you are using Adobe Acrobat Professional, you can take the following steps:
- Open the file in Acrobat Professional.
- Select Print Production under the Advanced dropdown menu, then click on Convert Colours.
- Under output intent, select the corresponding 3DAP Profile. Beneath, tick preserve black and preserve CMYK primaries Then OK.
- Save your file.
