Hi,

there is a way to convert this cmyk black background to only 100 black?

Thank you for help

I am reluctant to post this without knowing the project details, however, as you just wish to change the background and the foreground and transition from background to hero image does not appear to be a concern... Here is an annotated screenshot of one possible method:

    I wonder how dense any Pantone Black can actually be in, for example, offset printing. 

    Lots of open questions …

    Yeah c.p,  intriguing, I suppose if the Pantone "special" Black really is a "rich black" it must be made up of coloured inks as well as black (when mixed).

    So this is not a 5 colour print run, I understand (am I right) that the standard CMYK black is being replaced by "Pantone Rich Black" in this scenario. I wonder if that’s a nice black for text?

    And the press can take 100% too! Surprising.

     

    I hope this helps

      Image quality will suffer. So yes, but why? Some CMY is desirable, for increased density and registration on press.

       

      The sample provided above is RGB and PNG (PNG does not support CMYK).

       

      What file format is the original (TIFF, PSD, JPG etc).

       

      What CMYK ICC profile?

       

      How will the file be printed?

          This image will be linked to an Illustrator file that use 100 black.

          If the AI project use only 100 black, even the psd linked image must use 100 of black and not rich black created using all four values of cmyk.

          Say what? 

          Do you mean that the ai-file has a solid background of 100% of some Pantone black that the psd image has to match that?
