I was asked to generate a PDF type A-3 using XSL-FO with Apache FOP configuration. The PDF is already generated but it can't be validated

error : A device-specific color space (DeviceGray) without an appropriate output intent is used.

I think the issue will be related to the FOP configuration, this is the one I used:

<fop version="1.0">

  <!-- Base URL for resolving relative URLs -->
  <base>.</base>
  
  <!-- Source resolution in dpi (dots/pixels per inch) for determining the size of pixels in SVG and bitmap images, default: 72dpi -->
  <source-resolution>72</source-resolution>
  <!-- Target resolution in dpi (dots/pixels per inch) for specifying the target resolution for generated bitmaps, default: 72dpi -->
  <target-resolution>72</target-resolution>
  
  <!-- Default page-height and page-width, in case
       value is specified as auto -->
  <default-page-settings height="11in" width="8.26in"/>
  
  <!-- Information for specific renderers -->
  <!-- Uses renderer mime type for renderers -->
  <renderers>
    <renderer mime="application/pdf">
    
      <version>1.4</version>
      <filterList>
        <!-- provides compression using zlib flate (default is on) -->
        <value>flate</value>
       
      </filterList>

Read the Apache FOP configuration, you will need an output colorspace specified in the pdf renderer filterList like:

 <output-profile>C:\FOP\Color\EuropeISOCoatedFOGRA27.icc</output-profile>

See https://xmlgraphics.apache.org/fop/1.1/configuration.html

Of course, you need to select the appropriate ".icc" file for your application.
