Export to A1 PDF from Photostop

[kolax]

I've created an A1 size poster (150DPI) with the width and length dimensions matching that of A1. I'm getting it printed at a place in town, however they said they preferred it to be in PDF format.

I'm not sure how to save it as an A1 PDF - if I go to print then 'save as PDF' I don't get an A1 option, or the ability to enter custom info.

How would I go about doing this?

EDIT: DOH! Found it under Export options which I overlooked! Problem solved!

Is used "Save As" (CMD+SHIFT+S) and selected "Photoshop PDF" as Format and did not change a thing an I got an A1 PDF out of it that opens in Preview.
If you want to take a look at it, here is the 5MB PDF output from PS CS5: http://dl.dropbox.com/u/10644330/MR...shots/MR_screenshots_05_2011/A1_SaveAsPDF.pdf
