EXPORTING PDF COMES OUT AT A SMALLER SIZE! Advice needed

[JARROD]

Hi. I have a series of PDFs to export for print. They are scaled at 10% of the print size

When I export them as PDFs, they are not the same size as the canvas.

A 100cm x 70cm canvas exported as PDF came out at 40cm x 28cm when imported back into the canvas to check sizes

I need these to export at the required size for banner print

Any advice would be greatly appreciated

Thanks

Because Pixelmator seems internally use px as units It requires to set 72dpi at your document creation: 70x100cm/72dpi:
