    Hello Everyone.

    I'm new to this forum and have a couple of issues regarding colour some of you maybe able to clarify.

    It's regarding Fogra 39 and my limited understanding of it.

    If someone could give me an idiots guide to how it work in 4 colour printing and how to deal with images with older profiles?
    Should I convert these? The images change appearance?


    Also a couple of other grey areas.

    When setting up my colour setting in CS6 I have an option to Preserve Numbers (Ignore Linked Profiles). What exactly is this?
    My understanding is that no CMYK values in Vector or Rasters are changed.
    Is this correct? If so what is the point of converting to Fogra 39?

    If an image has, for example, a SWOP coated proifile assigned to it and I place it in a document with Fogra 39 colour space, what exatly happens to the image?
    Does it become Fogra 39 when it is output?
    If I open the image in Photoshop and change the profile to 39 the image changes tonal value. Will this happen if placed in Illustrator or InDesign?

    Also when I output to pdf using only the Fogra 39 profile, what exactly is happening to the file created and the files used to create the pdf, are the colur values being altered?

    Many thanks

    Simon
