I created a template in Photoshop for the client to be able to edit it. The output is meant to be a 9-page A4 PDF. I tried saving the sourcefile as Photoshop PDF (after flattening each artboard) but I encounter two issues that I'd need help with:
ISSUE 1 - all artboards are exported together rather than individual pages (it should be one PDF page per one PSD artboard);
ISSUE 2 - even if I have one artboard only PSD document, it still exports in a strange format (not what the canvas nor the artboard are set to) - see the screenshot below for reference, and the source file attached.Wrong Save as Photoshop PDF output
I have encountered the same problem, yet I worked out that you can create a multiple page PDF by following this sequence:
FILE > EXPORT > SAVE > ARTBOARDS TO PDF
From there you can choose your preferences before exporting.
I think the artboards need to be arranged from top to bottom in the Layers panel, in order to structure the page numbers in the PDF — which is a bit odd considering you think they would be generated based on the artboard number.
Perhaps this is customisable in the presets when exporting the sequence.
