InDesign preflight throws an error on 2-color eps art

Greetings! Here's my issue:

Had a 2-color job open in INDY CC2017, ran a preflight that allows for spot and black only, and it flagged some of the placed eps files as containing C, M, and Y colors. I opened the eps’s to correct and didn’t find any violations. When the artist told me that they had created PDFs of their 2-color art and they separated fine, I tried placing the PDFs. I then ran my preflight, and the same artwork passed as 2-color. Any ideas what is going on there?

I'm prepared to share the INDY file and my preflight 2-color preset if needed.

System:

MacPro, 3.5GHz, 6-Core Intel Xeon E5, 32GB memory

Software: Adobe CC2017, InDesign 2017

Thanks for any help! Rusty.

Adobe recommends using the native ai format when placing ai files into InDesign.

Official redommendation of Adobe people is always PDF/X-4, but it is true, AI works as fine as PDF/X-4 does.

Placing AI just gives you the PDF portion of the file anyway.

Simply never use EPS, use PDF/X-4 or AI files instead.

I had trouble loading your preflight settings, but I think that no matter what the Preflight is reporting, you are safe. I ran my own preflight and found just one spot color 157 and process black.

I opened the two EPS files in Illustrator. Only one color, the coral/melon color, is a spot color 157U. The others are all percentages of process black.

If I open the PDF and check Separations in the Output Preview panel, turning off CMY inks shows what you see in the screen capture below. It would appear that there are 2 inks in the PDF: 157 and process black.

I assume you opened and checked the EPS in Illustrator? Is the EPS all vectors—no images?

Did you try deleting all unused swatches so you only have Black and the spot color, and then Swatches>Add Used Colors? That will put any non swatch colors into the Swatches panel. Here you can see what appears to be a white fill actually has some CMYK

Greetings Rob.

Tried your technique on a couple of offending eps files. There were no extra colors in the pallet, and when I 'added unused' no new colors were added back in.

That is a cool trick to remember tho. Thanks.

If you're willing to share one of the placed EPS files that exhibited the problem, I will take a look at it.

Hi Barbara.

Sure. Thanks for being willing to help. From this eps you'll be able to generate a PDF that will create 2 plates only, but try it yourself.

What's the best way to share the file?

What's the best way to share the file?

Dropbox. Or your CC subscription lets you share files and folders you put in your local Creative Cloud Files folder:

/Users/~username/Creative Cloud Files

From the Creative Cloud App choose Assets>View Archive then under Files choose All and from there you can choose any file or folder and get a public link
