I have used PDFCreator 0.9.8/ghostscript 8.64 for a looong time, because if I update the program, joined PDF-files ALWAYS end up in black and white PDF-files (actually grayscale).
Last time I updated and got that problem, I could reinstall 0.9.8 and making it work again, but this time, what ever I do, the joined files ALWAYS becomes BW.
I have tried to uninstall 1.7.1, cleaning files and reg (with Glary AND ccleaner) and reinstall 0.9.8 again, but that doesn't fix the problem like last time. I have tried with other earlier ghostscripts with no difference.
When I use the virtual printer in programs with colors in, the PDF-files are in colors. It is only when I join files the result becomes BW. It makes no difference in PDFArchitect or Foxit.
It runs under WinXP Pro SP3 with Comodo firewall/viruscanner.
The PDF-files are usually from a Brother 135C scanner (make any difference?).
yes it is odd, I am not able to reproduce this here. You have the correct version of the pdfcmon.dll It is normal installing/uninstalling/activating the PDF Architect doesn’t influence PDFCreator, they aren’t directly connected to eachother, but why the merged files are b/w is a mistery
