Always check the pdf before printing from it. Interesting. AFAIK png-graphics with alpha channel are still outside the PDF 1.3 spec, so your approach might as well result in a 100% white box on top of the background image. The correct approach would be to combine the background image and the white transparent box inside Gimp and place that image in Scribus. The best way is to create a PDF with transparency (1.4) and print that from Adobe Reader (or Adobe Acrobat if available) to PS. AR includes a very good transparency flattener that will transform any transparent objects into pieces of non-transparent objects where transparency is already blended with the background. When you have the PDF, you can transform it back to a PDF with ps2pdf. When you use Ghostscript's ps2pdf13 on a PDF 1.4 file it does something less sophisticated that results in large bitmaps (That's also the program Scribus uses when it creates version 1.3 PDFs) /Andreas
