Lets have a few file sizes for comparison. A Gimp xcf, not quite as large as yours 14172x23622 px (1.2m x 2.0 @ 300ppi) with a large graphic (a photograph) and some text in layers. Gimp shows this as 3.8 GB in memory. xcf file size 400 MB exports a pdf 286 MB Exported as a jpg, file size 21 MB and that exported as a pdf 300 MB Exported as a png, file size 130 MB, exports as a pdf 325 MB Conclusion, not much point exporting to jpeg/png for the purpose of creating a PDF. The xcf PDF did contain text in a vector format, otherwise with png/jpeg and everything flattened to a bitmap. Print resolution: Are you sure the printing company really requires 300 dpi or is that just general figure? A poster can have a reduced dpi depending on distance viewed. Some guidance see: http://www.northlight-images.co.uk/what-print-resolution-works-for-what-viewing-distance/ Printing process: Do you know how it will be printed? A modern commercial laser printer will print at 100 ppc (pixels per cm) and produce superb quality, but costs a fortune. Send them a jpeg. If offset printing then a CMYK pdf is often used. The tool for that is not inkscape it is the DP application Scribus. Want to print full size on A3 sheets to joint together as a check. Split the image up into separate parts. Set up some guides as A3 sized sections ( 3508x4960 px) Use Image -> Transform -> Guillotine Plenty how-to's on this if you search. rich: www.gimp-forum.net -- rich2005 (via www.gimpusers.com/forums) _______________________________________________ gimp-user-list mailing list List address: [email protected] List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
