(But you can toggle that on and off manually, too.) When Proof Colors is on, InDesign is displaying your whole document as though you were in CMYK. To tell InDesign’s Separations Panel to use that profile, choose View Proof Setup Custom, and then choose your new profile from the CMYK pop-up menu: When you click OK, InDesign automatically turns on the View Proof Colors feature. Windows: Right-click on profile and choose “Install Profile” Okay, so now you have a profile that will limit all RGB-to-CMYK conversions to less than 240% ink. Mac: Drag into HD/Library/ColorSync/Profiles/. (Ask them for “an ICC color profile for your press.”) After you get the profile you need to install it in the right place. This is great because it gives you real-time, accurate feedback about what CMYK colors are going to come out of InDesign. In a nutshell, if you open the panel (from the Window Output menu), then set View to Separations, and then hover your cursor over a color on the page, you can see the total ink coverage really easily: In this case, the cursor is over a black section of an image, and the total ink (look next to “CMYK”) is 238%. Separations Preview and Ink Limits Claudia McCue wrote a terrific piece about InDesign’s Separations Preview panel in, where she showed how you can use this panel both to view your color separations on screen and also find your total ink limit anywhere on the page. Fortunately, it’s easy to test for this in InDesign, and it’s even pretty easy to avoid if you use the correct CMYK conversion methods. (It is also often called “total area coverage” or TAC.) So a 240% TAC means there shouldn’t be any place on your page that has more than 240% total ink-which can happen pretty quickly in dark shadows where there is a lot of black ink.

Well, if you place 100% cyan and 100% yellow in the same place, that green color is called 200% total ink.
