Why have you got a "Spot black"? Is that a 4 colour black?
Just use the Black already in the swatches panel for all blacks, except where you need rich blacks, which is usually on solid blocks of colour, or a black behind a photo or image that has a black background (creating the same build of black as the image or picture).
More info needed please
Sorry - should have been clearer.
I have a 4 colour file with a spot colour called 'Text black'. We produce childrens books so set all our books up as 4 colour with all the text set up as a 5th colour (spot) so we can print different foreign editions.
I should just point out that this is just a problem with strokes. When i perform a find and replace with the text this works fine.
make a copy of the default [Black] swatch and double-click it to open the swatch definition. Rename it to anything you like, then change the type to spot and click OK. THis swatch will not overprint by defualt the way the [Black] does, but you can do a GREP search for .+ to find all text, then set the change formatting to use the spot color for character color and check the overprint fill box. Even better would be to create styles that use the spot color and set the overprint directly in the style.
Thanks Peter for your help but i couldn't get it to work. For an example I created a blank new document and drew a simple line. I created a new swatch called text black and defined it as a spot colour and applied it to my line. Now I can't find a way of converting this line to overprint withing the find and change. I am going through the find and change option and changing it there - is this the best way. When i do a find and replace it changes my line to process black?
Thanks again for your help!
That looks like it might be a bug in Find/Change. I can work around this by creating an object style to apply the stroke with overprint, but unfortuantely you need one for every stroke weight you've used -- you can't, appaerntly, ignore weight and just turn on overprint in the style.
