Can someone tell me what I'm doing wrong here?\n\nI'm trying to send a booklet to get printed at an outside printer.\n\nFirst thing I did with one of the PSD files (the booklet is divided in\n"sheets") is convert all type to shape, so there are no problem font issues.\n\nThen I flattened all image layers to save space.\n\nResult : 35 MB file, which includes one layer for the pixel data, and a few\nfor the type, which is now uneditable due to being converted to shape.\n\nSo far so good.\n\nThen I try saving this 35 mb PSD file as a PDF file (which the printers now\ninsist on) but the resulting file is gigantic. 900 MB! Not because of the\npixel data (I've set Acrobat to not upsample or downsample in any way) but\nbecause of the vector data (formerly the text portions).\n\nOne of the "sheets" has as many as 16 layers of vector data (which I'd\ncombine if I could, but Photoshop doesn't seem to allow it, other than\ncombining as a smart object, which rasterizes on the output - a bad thing).\nRemoving the vector data and saving again confirms that these layers are the\nculprits.\n\nWhy is vector data several times heavier than pixel data in a PDF file? This\nmakes no sense. How am I supposed to deliver this thing to the printer at\n900mb per sheet, when 35mb was enough in PSD format?\n\nCan anyone shed some light here?
