Contents version 1 7 Reveal overprinting were to allow both circles to be full size on their separations the result would be something like this So the inks would mix to make blue Many design tools like Illustrator and QuarkXPress allow you to choose whether items are to overprint Always remember that overprinting is a property of the item on top in the example above the cyan circle The item beneath does not need to be overprinting since it is the action of the top object to knock it out or not It is a common mistake to think of overprint as needing to belong to the bottom object the magenta circle because this is the object that changes shape on the printing plate Finally if you want to see whether items really overprint here is an example that actually uses overprinting All the above examples are faked so that they print consistently In this example the cyan is set to overprint Why should I care about overprinting Overprinting may seem a convenient way to design certain kinds of effect However overprinting is not a general solution to this and in particular it will only appear in certain situations 1 Overprinting is as its name suggests related to printing That means it does not normally have any effect on screen This is potentially serious it means that the PDF file potentially displays on screen and prints differently Contents version 1 7 Reveal overprinting 2 Overprinting is not normal

23. eneral case outside the publishing area only a tiny fraction of systems are calibrated For some people it is very important not to have profiles A particular case is CMYK colours Commonly people will design with a specific mix of CMYK colours For example they may design with a colour in mind called warm red knowing that they require 100 magenta and 80 yellow on their printer or press If you have CMYK profiles you are asking the printer to change colours to match the profile Even if the profile you use exactly matches your printer some conversion can take place Although the result should look the same the conversion may lose information like overprinting So for many people removing CMYK profiles is important Acrobat Distiller can be used to set profiles for files also profiles may come from the applications used to create the pages and may come separately for different graphics Reveal profiles tagged colour can be used to check the usage is consistent What am I seeing You may see the following entries in the profiles tagged colour list You will see only the ones that are used in the file This list is alphabetical CMYK untagged this is the normal CMYK which is what is wanted in most pre press workflows CMYK with profile lt name gt this is CMYK tagged with an output profile This affects on screen display Caution CMYK profiles have an effect which may be unwelcome in many workflows It may caus
