Whenever you put any kind of transparency effect on a page, a Drop Shadow or a Photoshop image with a transparent background or whatever, InDesign has to do a bunch of extra calculations in order to ensure that what you are seeing on screen is as accurate as possible. However, the transparency effects all work slightly differently depending on whether you are working in a CMYK or an RGB space. So in order to get an accurate display, you need to tell InDesign whether your document is destined for the screen or for a printing press and the way you do that is to go the Edit menu, scroll down to Transparency Blend Space and choose either Document RGB or a Document CMYK. This document is set to CMYK, which means that I expect it to go to a printing press. I expect it to actually separate out to CMYK plates. But if I were making an interactive document like a PDF or a SWF file then I would definitely want to change this to RGB. Another good reason to use RGB would be if the final document was going to be printed on an inkjet printer or even a color laser printer. Those kind of printers do use CMYK inks or toners or crayons or spray or whatever but they tend to work best when you treat them like RGB devices. You may have run into that before if you were printing on an inkjet printer or a color laser printer and all of a sudden the colors on your screen look really dull and kind of muted in the output. It's because those kind of printers usually want to be RGB devices. So you should be setting this to Document RGB. Now don't change this just to get like an accurate proof or something, we will talking about proofing later in this chapter, but you only change this to RGB if the final output is going to be to an RGB device, inkjet, color laser printer or something like that. If it's going to be printed on the printing press leave it set to Document CMYK. I want to show you one other instance where transparency can have a huge effect on your document. I am going to go the second page of this document with a Shift+Page Down and I can see that I have imported a big grayscale image here. I will zoom into 200% with a Command+2 or Ctrl+2 on Windows and then I will go to the View menu and turn on High Quality Display, so we see this little bit more accurately. Okay so I have got a grayscale image on the page and it's looking pretty good and let me pan down here. Now I am going to grab this object over here and change its Opacity just a little bit.
But now when I do this I will set it to maybe 90%. Now when I do this watch that grayscale image. I just hit Enter and suddenly the grayscale image totally changed. It got way lighter. What happened? Well watch this, let's put this back to a 100% again. Now it got darker again. What is going on? Well that all has to do with whether this transparency on this page or not. Right now, if I look into the Pages panel I can see there is no Transparency icon here, so there is nothing on this page that has any transparency and as soon as I add a transparency to the page, InDesign had to force the entire page through the Transparency... whatchamacallit, the thing that makes the document look more accurate. Well, when I did that, the grayscale image changed. It actually got more accurate. It actually looked more like what it was going to look like on a printing press because I am in CMYK mode here. So that's a good thing but it's a also kind of a scary thing because you usually don't like your document to change that much. Just if you make a little change like add transparency. Now let me show you a trick. There is another way to kind of fool InDesign into working in the Transparent mode even when you don't have transparency on your page and that is to go into Overprint Preview mode and when you do that everything on your page looks a little bit more accurate. They call it Overprint Preview because it's supposed to preview your overprints, but in reality it should be called 'make it all a little bit more accurate than it normally is.' I guess that wouldn't fit in the menu, so they couldn't put that in there. So turn on Overprint Preview and you can actually work with that on and you won't have those radical changes whenever you add transparency on your page. So that Overprint Preview and the Transparency Blend Space both make a big difference in ensuring color consistency. But even more important are the controls in the Color Settings dialog box. So let's take a look at those next.
