Saving InDesign pdf with JobOptions
Hello, I am using InDesign CC 2017 to save my clients' book design. When I use Full Bleed Lulu.joboptions downloaded from your site just now I get the following warnings:
1) The preset specifies a profile that is not available. The working CMYK profile will be used instead.
2) The preset specifies an output intent profile which is not supported by InDesign. An alternative profile has been specified in the Output panel.
Can these files be submitted as they are, or do I need to save another way?
Thanks in advance for your help.
