Can someone tell me what I’m doing wrong here?
I’m trying to send a booklet to get printed at an outside printer.
First thing I did with one of the PSD files (the booklet is divided in "sheets") is convert all type to shape, so there are no problem font issues.
Then I flattened all image layers to save space.
Result : 35 MB file, which includes one layer for the pixel data, and a few for the type, which is now uneditable due to being converted to shape.
So far so good.
Then I try saving this 35 mb PSD file as a PDF file (which the printers now insist on) but the resulting file is gigantic. 900 MB! Not because of the pixel data (I’ve set Acrobat to not upsample or downsample in any way) but because of the vector data (formerly the text portions).
One of the "sheets" has as many as 16 layers of vector data (which I’d combine if I could, but Photoshop doesn’t seem to allow it, other than combining as a smart object, which rasterizes on the output – a bad thing). Removing the vector data and saving again confirms that these layers are the culprits.
Why is vector data several times heavier than pixel data in a PDF file? This makes no sense. How am I supposed to deliver this thing to the printer at 900mb per sheet, when 35mb was enough in PSD format?
Can anyone shed some light here?
