Preflight for 100% black and color profiles

[McShaman]

I am trying to build a preflight clients to be able to test their logo files against before they submit it to us to be printed.

The printed product is to be printed 100% black only. I would like to be able to test for any instances of anything other than 100% black which I think I have gotten working by using `Object is 100% black` property.

I also want to enforce color profiles not be enabled when generating the PDF. This one I am not too sure about... I am currently getting some results with `Profile Size in Bytes grater than 0`. It seems a bit hacky and I am not sure that it will work exactly as expected.

If I save out a PDF from Illustrator and under `Output > Profile Inclusion Policy > Include All Profiles` I get errors from both the `Object is 100% black` and the `Profile Size in Bytes grater than 0` tests... Even though there are only no elements other than 100% black elements.

I am not sure if I am doing this the best way or why I get this response from the test.

I would certainly expect that if you including profiles from Illustrator, that it will fail the test. Don't be misled by "colour" in "colour profile". A colour profile is nothing to do with whether a file has colour. You would have a colour profile for black, just like everything else. It is about how the colour in the PDF is to be understood. You are actually going against industry norms and some people may find it difficult to meet your requirements.

I understand that color profile has nothing to do with detecting color. The reason why I want the profiles stripped is because the product that the logos are going to be printed on are going to be be straight black. I dont want any chance of some crazy embedded color profile affecting how the black of the logo is printed when it goes through the rip.
