1 00:00:00.05 --> 00:00:02.02 - [Voiceover] In this movie I'll show you another way to 2 00:00:02.02 --> 00:00:03.04 troubleshoot a document. 3 00:00:03.04 --> 00:00:06.00 This time using what's known as overprinting. 4 00:00:06.00 --> 00:00:07.08 Which allows you to print one ink 5 00:00:07.08 --> 00:00:09.09 directly on top of another. 6 00:00:09.09 --> 00:00:11.04 So for example, notice here, 7 00:00:11.04 --> 00:00:14.00 I've got this gradient version of my logo. 8 00:00:14.00 --> 00:00:17.00 I'm still using the same three inks, by the way. 9 00:00:17.00 --> 00:00:18.06 And you can confirm that's the case 10 00:00:18.06 --> 00:00:20.00 by going up to the Window menu 11 00:00:20.00 --> 00:00:22.06 and choosing the Separations Preview command. 12 00:00:22.06 --> 00:00:23.08 In my case the panel's empty 13 00:00:23.08 --> 00:00:26.01 because I'm working inside an RGB document. 14 00:00:26.01 --> 00:00:27.07 So I'll go up to the File menu, 15 00:00:27.07 --> 00:00:31.07 choose Document Color Mode and then choose CMYK Color. 16 00:00:31.07 --> 00:00:33.05 And I want you to see how we're gonna see 17 00:00:33.05 --> 00:00:36.02 a little bit of color shifting on screen. 18 00:00:36.02 --> 00:00:39.00 That actually is meaningless, by the way. 19 00:00:39.00 --> 00:00:41.05 Again, because we're working exclusively with spot colors, 20 00:00:41.05 --> 00:00:43.08 they're actually gonna print actually the same, 21 00:00:43.08 --> 00:00:47.06 whether the document is set to RGB or CMYK. 22 00:00:47.06 --> 00:00:50.09 It's just a function of the screen display and nothing more. 23 00:00:50.09 --> 00:00:52.09 And so, to gain access to my inks here, 24 00:00:52.09 --> 00:00:55.09 I'll go ahead and turn on the Overprint Preview checkbox. 25 00:00:55.09 --> 00:00:58.01 And then I'll go ahead and turn off CMYK, 26 00:00:58.01 --> 00:01:01.02 because after all, I'm not using CMYK colors. 27 00:01:01.02 --> 00:01:03.02 And then, to demonstrate that's the case, 28 00:01:03.02 --> 00:01:05.07 I'll go ahead and turn off PANTONE 325, 29 00:01:05.07 --> 00:01:07.03 so you can see this is everything 30 00:01:07.03 --> 00:01:09.06 that's gonna print on the blue and black plate. 31 00:01:09.06 --> 00:01:12.00 Problem is, in addition to this little edge here, 32 00:01:12.00 --> 00:01:13.07 which I'm not so worried about now, 33 00:01:13.07 --> 00:01:16.01 because I have all these gradients at work. 34 00:01:16.01 --> 00:01:17.08 But I am concerned about this, 35 00:01:17.08 --> 00:01:21.02 notice if I turn off PANTONE Black 6 C, 36 00:01:21.02 --> 00:01:25.08 I've got a knockout going up here at the top of my logo. 37 00:01:25.08 --> 00:01:27.02 So this is what the artwork looks like 38 00:01:27.02 --> 00:01:28.06 with that ink turned on, 39 00:01:28.06 --> 00:01:31.01 and here's how it looks with the ink turned off. 40 00:01:31.01 --> 00:01:33.02 And that's not the effect I'm interested in. 41 00:01:33.02 --> 00:01:37.03 I want no knockout to occur up here at the top of the logo. 42 00:01:37.03 --> 00:01:38.06 And so, what I'm gonna have to do 43 00:01:38.06 --> 00:01:40.09 is turn those things back on like so. 44 00:01:40.09 --> 00:01:42.02 Just so I can see what I'm doing. 45 00:01:42.02 --> 00:01:44.02 And then I'll go ahead and click on this shape right there. 46 00:01:44.02 --> 00:01:46.01 And I want you to see what's going on. 47 00:01:46.01 --> 00:01:47.05 If I drag it off to the side, 48 00:01:47.05 --> 00:01:49.01 you can see that we've got a gradient 49 00:01:49.01 --> 00:01:51.00 that starts black at the top 50 00:01:51.00 --> 00:01:54.05 and it's set, by the way, in that PANTONE Black 6 C, 51 00:01:54.05 --> 00:01:57.05 and then it becomes transparent toward the bottom. 52 00:01:57.05 --> 00:01:59.05 All right, so to avoid the knockout, 53 00:01:59.05 --> 00:02:01.08 I'll just go ahead and press CTRL + Z, or CMD + Z on a Mac, 54 00:02:01.08 --> 00:02:03.07 to undo the movement of that artwork. 55 00:02:03.07 --> 00:02:06.01 And then, I'll go up to the Window menu 56 00:02:06.01 --> 00:02:08.04 and choose the Attributes command, 57 00:02:08.04 --> 00:02:11.00 which will bring up the Attributes panel right there. 58 00:02:11.00 --> 00:02:13.08 And notice this checkbox right there, Overprint Fill. 59 00:02:13.08 --> 00:02:15.03 I'm gonna go ahead and turn it on. 60 00:02:15.03 --> 00:02:16.06 But as I do, I want you to notice 61 00:02:16.06 --> 00:02:18.02 what's happening on screen. 62 00:02:18.02 --> 00:02:20.08 As soon as I turn on that Overprint Fill checkbox, 63 00:02:20.08 --> 00:02:23.03 I darken up the artwork underneath. 64 00:02:23.03 --> 00:02:25.04 And that's because I'm now printing this gradient 65 00:02:25.04 --> 00:02:27.08 on top of the one in the background. 66 00:02:27.08 --> 00:02:29.01 And to confirm that's the case, 67 00:02:29.01 --> 00:02:31.03 I'll go ahead and hide my Attributes panel, 68 00:02:31.03 --> 00:02:33.02 I'll click off the shape to deselect it, 69 00:02:33.02 --> 00:02:36.00 I'll bring back up my Separations Preview panel, 70 00:02:36.00 --> 00:02:37.02 and now, notice what happens 71 00:02:37.02 --> 00:02:40.04 when I turn off PANTONE Black 6 C. 72 00:02:40.04 --> 00:02:43.04 You can see, I no longer have a knockout up there 73 00:02:43.04 --> 00:02:44.08 at the top of the shape. 74 00:02:44.08 --> 00:02:46.07 Rather I'm just printing that black ink 75 00:02:46.07 --> 00:02:49.09 on top of the blue 285. 76 00:02:49.09 --> 00:02:52.08 Another great use for overprinting is with text. 77 00:02:52.08 --> 00:02:54.03 So I'll go ahead and switch over 78 00:02:54.03 --> 00:02:56.01 to my name plates document here. 79 00:02:56.01 --> 00:02:58.05 Again, my Separations Preview panel is blank 80 00:02:58.05 --> 00:03:01.03 because I'm working inside of an RGB document. 81 00:03:01.03 --> 00:03:03.02 And so, I'll go up to the File menu, 82 00:03:03.02 --> 00:03:06.05 choose Document Color Mode and choose CMYK Color. 83 00:03:06.05 --> 00:03:08.08 Now I'll turn on the Overprint Preview checkbox, 84 00:03:08.08 --> 00:03:11.01 here inside the Separations Preview panel. 85 00:03:11.01 --> 00:03:14.01 And I want you to notice, this time if I turn CMYK off, 86 00:03:14.01 --> 00:03:16.02 I'm turning off a lot of ink. 87 00:03:16.02 --> 00:03:18.01 And that's because the only thing that's set 88 00:03:18.01 --> 00:03:22.04 in this PANTONE 122 is these yellow rectangles right there. 89 00:03:22.04 --> 00:03:25.01 And as you may recall from a previous chapter, 90 00:03:25.01 --> 00:03:27.01 the only thing that's real inside this document 91 00:03:27.01 --> 00:03:28.04 is the first name plate. 92 00:03:28.04 --> 00:03:32.01 The others are repeated with a dynamic transform effect. 93 00:03:32.01 --> 00:03:34.05 All right, so I want you to see what's going on here. 94 00:03:34.05 --> 00:03:37.07 I'm gonna turn off the black ink so that we can see 95 00:03:37.07 --> 00:03:41.09 that all of this text is actually set in multiple inks. 96 00:03:41.09 --> 00:03:44.08 So, if I were to turn off magenta and yellow for a moment, 97 00:03:44.08 --> 00:03:47.08 you can see that we've got some action on the cyan plate. 98 00:03:47.08 --> 00:03:50.03 We also have something happening with the magenta, 99 00:03:50.03 --> 00:03:52.09 as well as yellow even. 100 00:03:52.09 --> 00:03:54.06 And then, of course, black. 101 00:03:54.06 --> 00:03:57.05 Now, the reason that this is a problem is twofold. 102 00:03:57.05 --> 00:04:00.02 First of all, I could run into some trapping problems. 103 00:04:00.02 --> 00:04:01.03 And that would be caused 104 00:04:01.03 --> 00:04:05.00 by a slight amount of misregistration on the plates. 105 00:04:05.00 --> 00:04:06.07 And what would happen in that case is 106 00:04:06.07 --> 00:04:08.07 that the text set against the yellow rectangle 107 00:04:08.07 --> 00:04:12.07 might end up having some very slight white edges. 108 00:04:12.07 --> 00:04:15.02 Which would be a problem where the paper is showing through. 109 00:04:15.02 --> 00:04:17.01 And then, where we're seeing the word Author, 110 00:04:17.01 --> 00:04:19.07 imagine if the black and the magenta 111 00:04:19.07 --> 00:04:21.05 and the yellow and the cyan print 112 00:04:21.05 --> 00:04:23.00 slightly off of each other, 113 00:04:23.00 --> 00:04:25.00 then we're gonna have some colorful edges. 114 00:04:25.00 --> 00:04:26.02 Which is not what I want. 115 00:04:26.02 --> 00:04:28.05 And so to take care of that problem, here's what you do. 116 00:04:28.05 --> 00:04:31.03 I'll just go ahead and scroll up to the top text right there 117 00:04:31.03 --> 00:04:34.02 and I will go ahead and click on that text 118 00:04:34.02 --> 00:04:36.05 and then Shift + Click on the word Author. 119 00:04:36.05 --> 00:04:38.02 And what you wanna do is Shift + Click 120 00:04:38.02 --> 00:04:41.00 on the first color swatch, up here in the Control panel. 121 00:04:41.00 --> 00:04:42.08 And notice that we have all kinds of action 122 00:04:42.08 --> 00:04:44.03 where the cyan, magenta, yellow 123 00:04:44.03 --> 00:04:46.01 and black inks are concerned. 124 00:04:46.01 --> 00:04:48.02 This is what's known as a rich black, by the way. 125 00:04:48.02 --> 00:04:50.01 It ends up making the black darker, 126 00:04:50.01 --> 00:04:52.02 which is generally a really great thing. 127 00:04:52.02 --> 00:04:54.01 Except it doesn't work so well for text. 128 00:04:54.01 --> 00:04:56.01 Generally speaking, when you're working with text, 129 00:04:56.01 --> 00:04:59.01 you want it to hit the black ink and nothing more. 130 00:04:59.01 --> 00:05:01.06 And to make that happen, I'll change the cyan, 131 00:05:01.06 --> 00:05:05.05 magenta and yellow values to 0%, like so. 132 00:05:05.05 --> 00:05:08.07 And then, I'll change the K value to 100%. 133 00:05:08.07 --> 00:05:10.08 Then I'll press the enter key or the return key on a Mac, 134 00:05:10.08 --> 00:05:12.06 in order to make that change. 135 00:05:12.06 --> 00:05:15.01 And now what we have, is a weaker black. 136 00:05:15.01 --> 00:05:17.05 But it's gonna work out better for this artwork. 137 00:05:17.05 --> 00:05:20.08 And we can see that's the case by going to the Window menu, 138 00:05:20.08 --> 00:05:23.05 and choosing the Attributes command, once again. 139 00:05:23.05 --> 00:05:26.03 And then you wanna turn on Overprint Fill. 140 00:05:26.03 --> 00:05:27.08 And now notice what happens 141 00:05:27.08 --> 00:05:29.09 if I bring back the Separations Preview panel 142 00:05:29.09 --> 00:05:32.07 and I turn off black, in fact, I'll just go ahead 143 00:05:32.07 --> 00:05:35.01 and press CTRL + Shift + A, or CMD + Shift + A on a Mac, 144 00:05:35.01 --> 00:05:36.08 in order to deselect the text 145 00:05:36.08 --> 00:05:38.08 and then I'll turn off the black ink. 146 00:05:38.08 --> 00:05:42.00 And you can see, we no longer have a knockout. 147 00:05:42.00 --> 00:05:44.08 And we also have no action, here in the yellow ink, 148 00:05:44.08 --> 00:05:47.02 or the magenta ink or the cyan. 149 00:05:47.02 --> 00:05:50.01 So we've got a lot happening here inside the photograph. 150 00:05:50.01 --> 00:05:52.09 But we have nothing happening where the text is concerned. 151 00:05:52.09 --> 00:05:54.07 Until we turn on the black ink. 152 00:05:54.07 --> 00:05:57.09 At which point, we can see that text once again. 153 00:05:57.09 --> 00:06:00.06 And so, thanks to the fact that we're isolating the text 154 00:06:00.06 --> 00:06:01.08 to just the black ink, 155 00:06:01.08 --> 00:06:03.09 we're not gonna have any registration problems 156 00:06:03.09 --> 00:06:05.07 where the word Author is concerned. 157 00:06:05.07 --> 00:06:08.01 And, we're not gonna have any trapping problems 158 00:06:08.01 --> 00:06:10.06 where my name interacts with the yellow rectangle 159 00:06:10.06 --> 00:06:11.06 on the background. 160 00:06:11.06 --> 00:06:14.09 And because I'm printing my name in two inks, 161 00:06:14.09 --> 00:06:20.00 black and PANTONE 122, I'm gonna get a richer black as well. 162 00:06:20.00 --> 00:06:21.08 And that's how you troubleshoot a document, 163 00:06:21.08 --> 00:06:25.02 two documents in our case, by overprinting inks. 164 00:06:25.02 --> 00:06:27.03 Here, inside Illustrator.
