problem with Spot Color and OverPrinting

[Michael Shonle]

Hi, just starting out with Designer, so not sure if it's operator error or a bug, but I'm having problems with an Overprinting Spot Color getting "knocked out" by other items on other layers.  I defined an Overprinting Spot Color and used it to fill an area on one layer, then added various text and line items on an upper layer.  When I export it as PDF/X-1a, the area that’s supposed to be overprinted gets knocked out by the other items.  Interestingly, I noticed that if I specify an Opacity of less than 100%, then it seems to keep the overprint for lines but not for text.   I have all the layer modes set to ‘Passhrough’ except the first (which is only used for testing the overprint region and not included in the final output.

So, is there something I’m doing wrong or is this a bug?

 

Thanks.

-Mike

Hi Michael Shonie

 

Welcome to the forums

 

I think this is due to setting overprint on the bottom layer but not on the objects you have placed on top. Overprint works downwards, so you need to set overprint on the actual object you want to overprint rather than the object underneath that you don't want knocked out

Thanks so much for your fast and accurate response!  I was looking it at from the wrong point of view.  Upon re-reading the documentation, it still wasn't clear which way it applied, so maybe consider being more explicit there?

Thanks again,
