Although there is a Macro which you can use from OberonPlace, the same thing is available on the Edit menu in the Replace menu--so Color Replacer, move over. In this one, you can replace a complete color space, either fill or outline--not both so if you have both to do, you have to run it twice, it will not however correct textures which have been made RGB, these must be edited individually in the Texture dialog box. However, it beats editing 40 zillion lines of code by hand and evaluating if you think the individual conversions from RGB to CMYK are worthwhile. It is a real timesaver. But if there are PowerClips, they must be edited before you run the Color Space Replacer, then after that it is pretty much a piece of cake. So it is a real timesaver. It however looks for any value percentage-wise, so if you have zero fills in a spot color, it will not find those if you are say, searching for a spot color replacement. It is best to limit your search to a selection, so that if you have a ton of replacements to do, it doesn't take forever. It always happens that you find something you wish you had changed and then you can't stop it until it finishes.
This can be uses as a color replacer for spot color as well but it will not find either fill or outline of zeroed out spot color. You may wonder for what reason you would want a zero percentage value for a spot color? The answer is blends which can be used to simulate drop shadows. If you made a blend, for example, using white, a blend between spot color and regular white will convert the spot color percentage values in a blend to CMYK. Since this is a real no-no with spot color separations, you use zeroed out spot color. But as designs change or sometimes as it may happen, you have artwork supplied done by someone else who does not understand or only partially understands spot color, you can get a nightmare to fix. And then there are changes in design, customers who want to try the design in one color after another, and then you have to fix it. Some of these changes you can't see with the naked eye, such as zero percentage spot color.
Every one working for a commercial printer may not have the expertise to output every job, and that they can do some or most goes to show you that you don't have to be an artist to make DRAW work. However, there are times when the automatic trapping in DRAW is undesireable and when you may want to print one layer at a time preserving all of your manual traps. Turning off the print icon in Object manager on any other layer is required to do this. And if you have to run the job several impositions up, then you have a more complex situation in duplicating, to be sure your duplicates are placed on the right layer because if you grab it all at once, your duplicates go just onto one layer and not into the little segregation you may have just created. And so if there are others who may output a more difficult job, leave instructions because you'll end up repairing it. Not all using a graphic application understand all the ways that app can be used and you can't always explain it to them. I don't want to leave rogue separations in my files, nice a tidy when it is all tied up and saved. Easier for me too when I don't have to deal with it for six months to a year.
So the Replacement wizard doesn't just find words to replace, it can replace many more items in your document and speed up your work flow if you learn how to use it.
Conversely in DRAW since it is targeted for print and if you are designing for the web or have other reasons you want to work in RGB, you can convert also the other direction. This will also convert your drop shadows to RGB. Just not textures as noted above.
