Printing Separations knockout ? Hi, I’m a graphic designer at small printing shop. We have a job with a 2 color logo (which is a black chair with a black pattern on the red upholstery). The press operator has asked that we print black on top of the red field so he doesn’t have to deal with the extra tight registration required in the pattern of the chair.
I created the logo in illustrator with a black pattern on a solid red field but when I send the file as separations the red plate has white where the black lays on top. I’m new at pre-press design so my vocabulary is lacking a bit but I think this is a knockout issue. Does that make since? How do I get it to send as a solid red so we can lay black on top?

Is it not standard black (ie rich black or a PMS?) __________________ Reply from C If it's 100% black, a lot of rip softwares (and a lot of design software) will make it overprint automatically. If it's a black spot color (i.e. Pantone Black) it may not automatically overprint, so you may have to tell it to overprint. __________________ Reply from A If you've used a pattern fill, you may have to "Expand Appearance" on the object and make sure it's solid K. there may be some other colour involved in the default illy pattern fills...

Me too. AFAIK Inkscape does not handle separations at all. I would do it manually by cutting the design into layers of paths that share a colour. You can imagine that this would be quite complex - esp. if you have clips that have many colours within. Not sure how I would handle it really. Might take it all out to Gimp, or see what Scribus to PDF can do.
Be doing a sign project soon that may go to screen-printing, so I need to get this sorted sometime.

Within Inkscape I think its not possible, but exporting our svg to Scribus it can be donde. Scribus have prepress nice features. Take a look at: http://wiki.scribus.net/canvas/Pre-Press%C2%A0theres a section for Overpinting and Knockout.
