(If you don't have 'Adobe PDF Printer' in your printing options please read this follow-up article on using just Preview)
Let’s say you design a card 11” wide by 6” high for commercial printing. Here is how to do it:
- click Page Setup in Document Inspector (or go to Page Setup from File menu);
- in ‘Format for’ choose Adobe PDF and in Paper Size drop-down menu choose Manage Custom Sizes;
- Custom Page Sizes dialogue opens;
- at the bottom of the left column click plus sign to create new page format with dimensions of your card;
- double click 'untitled' to name it, say 'Doug's Card';
- then, on the right, type in your dimensions 11" wide x 6" high (mine are set in cm, but it doesn't matter);
- set margins the way you want them to be, but remember to allow 3 mm (0.12") for printer's crop, click OK;
- now, in Page Setup dialogue, make sure that in Paper Size drop-down menu, 'Doug's Card' is selected and click OK. Your Pages document should change to the format you've created;
- next, process your card from Pages to CMYK PDF via Postscript, but DO NOT click Landscape in Page Setup, your dimensions will be preserved in the new PDF document.
