Hi,

I am facing some colour introduce error in PDF which is created from InDesign software.

In the .EPS figure the color mode is in Grey but if we load it in InDesign file and then create PDF the "DeviceN and Nchannel" colors are introduced. Please refer below screenshot and advise how to get the exact Grey which is present in the .EPS in the InDesign outputt PDF. 

Thanks,

Santhosh

How you set your Export Output tab will affect what happens to the grayscale. Here I’ve placed a Photoshop EPS grayscale and exported using the PDF/X-4 preset (No Color Conversion) vs. PDF/X-1a, which forces a conversion to Document CMYK where the grayscale outputs to the CMYK Black plate:

 

PDF/X-1a

 

PDF/X-4

 

AcrobatPro shows both exporting to the Black plate (not as a Spot color):

    Hi,

    Still the issue not clear in our end. We are using client supplied joboption in that the working space is Coated Fogra39. While creating PDF in this setting, we faced this issue. Unable to solve till now. I don't know why unnecessary "DeviceN and Nchannel" introduced.

      Hi,

      We are using client supplied joboption in InDesign. Once the PDF creation done in this settings we preflighted the PDF in Enfocus Pitstop Server and got below error.. Refer below screenshot.

      Hi @santhoshr29800103 ,

      my question was more about the why behind the error message.

      Why do you think there is a problem with DeviceN and Nchannel ?

      .eps is an evil, rusty file format.

       

      Did you try to convert all .eps to .ai?

        Hi Santhosh,

        1. what version of InDesign are you using?

        2. What settings were used to generate the PDF?

        3. The PDF will be used for printing?

         

        Best
