maritim Posted October 16, 2017 Share Posted October 16, 2017 How can I export a .pdf: grey (B&W) + spot colour. my grey is always cmyk ??? thx martim Quote Link to comment Share on other sites More sharing options...
MikeW Posted October 16, 2017 Share Posted October 16, 2017 The gray palette is a CMYK build despite what it will report to you if you check the color. Assuming your PDF export is to a CMYK profile, select anything gray, double click on the color proxy and the sliders will report 100% K (or whatever percent is appropriate for the swatch you chose from). But it isn't. So slide it down a skosh, then back to where it was or type in the value and press Enter. That should resolve it...after you have done all your gray items. I changed the gray palette to be shades of K the first time I ran into this issue. Mike Quote Link to comment Share on other sites More sharing options...
maritim Posted October 20, 2017 Author Share Posted October 20, 2017 thank you for your answer, I have to place a lot of pictures. (all B/W). they all end up cmyk. ? the printing house needs B/W +spot colour. my workflow: Affinity Photo (save as grey) -> Affinity Designer (document rgb/cmyk) -> place picture -> put on Spotcolour -> export .pdf (grey + spotcolour) = cmyk + spotcolour I also tried to convert the document to grey befor exporting. no difference. martin Quote Link to comment Share on other sites More sharing options...
MikeW Posted October 20, 2017 Share Posted October 20, 2017 True builds of Black will end up in only the K channel. True spot colors (not one of the Bridge or certain other Pantone spot color palettes) will also go to the appropriate channel. However, it sounds like you are colorizing a gray image with a spot color. Is that accurate? Or, are you simply adding elements that use a spot color?

maritim Posted October 21, 2017 Author Share Posted October 21, 2017 I don't colorize the picture. I just add elements that use spot color. The spot color export is fine, but the placed pictures jump to cmyk.? TESTX1a.pdf Quote Link to comment Share on other sites More sharing options...
MikeW Posted October 21, 2017 Share Posted October 21, 2017 Good as regards not trying to colorize the image. AD doesn't support duotoned images. So I am assuming from the name of the pdf that you used the PDF/X-1a profile? It appears you perhaps used the Black swatch from the Gray palette? That will always export as a mix of CMYK. One needs to open the color editor with the background selected and move the slider down a skosh, then back to 100% (or whatever the desired K component is suppose to be). I have rebuilt my grays to be true percentages of black. The image is an RGB image, or perhaps it was converted to such when the PDF was made. I extracted it, changed it to a grayscale image and inserted it into the AD file I made to recreate the file. I didn't really know what Pantone you used, so I just picked one. The attached ZIP has two files in it, the AD file and a PDF/X-1A file made from it. I didn't output printer's marks. Those will always separate to CMYK and I wanted to make sure there wasn't any CMY builds in the PDF. I didn't really look at what size you created your file and so sizes are different. Check the AD file I created. It is correctly K + Spot. Mike Desktop.zip Quote Link to comment Share on other sites More sharing options...
