After we have Converted the image to the correct color mode and also set up the channel docker, what is next?
Next we will be looking at the very important step of not only removing that K value, but also making a fake one.

All right, guys, In today's video, we're gonna be looking at how we can remove the K Channel from our C N. Y. K. And this will be for or should I say, within Photoshop. But before that, let's have a quick intro first, so today's video can be found on softwaretraining.co.za. We make short and easy to watch problem solving videos, and we also have daily updates back into the programmer. Now, in the previous video, we looked at converting this image to C. M. Y K and also setting up our actual C M Y K channels. Now, in today's video, we're gonna be looking at actually getting to the, um, some of the most important parts of this whole thing and that is removing the K and putting a new fake K. You can say so. The first thing that I want to do is I want to go on an image in the background. I'm just gonna remove this little lock so it doesn't give us problems now, you might not have the same problem, but I'm gonna do that for now. Then next up, what I wanna do is. I wanna go to the actual channels, then select our Black Channel. So the one right at the bottom and then there's a few ways we can do it. We can use shortcut keys, so I'll show both. So the first way is we can go, um, control a just with our mouse ho it here, they will select everything. Then, with this one selected, I'm gonna go control C and that will make a copy of our black channel. And I'll move back to our layers, and then I'm gonna just control d to deselect everything or Sorry. Um, yeah, control d and then I'm gonna make a new layer here at the bottom. So I'm just gonna click that create a new layer, or what I can do is go control shift in That will give us an option for a new layer. Say OK and then control V or paste our black layer. So now pretty much we have the base and then we have the black layer another way. We can do this without shortcuts, so I'm going to remove that we go to our channels and then we go to, um uh I think it was. Let me just find out. Select. And then we wanna go all so you can see control A So we select everything with our black one selected. We wanna go here to edit, we say copy. Then I'm gonna go to layers, click new here at the bottom next to the dust bin, made a new layer, then go to edit and click paste there. So that's the process we took without shortcuts. So if you, um your shortcuts may be different, you can still follow along. Now, next thing I'm gonna do is I'm just gonna quickly rename this bottom layer to C. M y. And then I'm gonna rename the top one to K. Now, I'm gonna just hide the K for now so we can see what we're doing and make sure your c m y layer or the bottom layer is selected. Then I'm gonna go to channels and then I'm gonna select on the black layer. So only that's active now from our actual colour Swatch here on top, we wanna make sure the foreground is black and the background is white. So, um, if you if you want to do that, you can always click on this arrow to switch between the two and then with the one selected, you just adjust the dragon to the black. In my case, I'll press X. It will swap it, drag it to the white, and then make sure the black is the front. Now, with this layer selected, you can just go shift and back space and then it's gonna ask us to fill this layer and I'm gonna say with background colour So that will be our white Say OK, and then there we go. Now it has made it white for us, So there's no more k k will be invisible. So if I click here on C m Y k, you will see the black layer is no longer there. So make sure. Like I said, you must be selected on the bottom layer. Now what I can do is if I go to a colour picker, go here between a hand or fingers. I click that you can see our K currently is zero. If I zoom in there now to get the K back without it being real K, I mean we will still convert it and flatten it But for that we're gonna bring our K layer back. We select it and then we want to go to our actual blending mode and set this to multiply. Now, if we pop this in and out, you can see it goes quite a bit darker. But, um, at the moment we are not relying on the K, we will still convert it. So at the moment, if you however, use your colour dropper on this area, you're still gonna find K, as you can see there. But we will sort that out in a little bit. At the moment, we've got about 18 K, but we will sort that in the next video because we just want to make a few adjustments just to, um, make sure this image pops a little bit more because at the moment it's still a little bit flat compared to the original. And, uh, you can go like this. It looks great, but with slight adjustments, we can really make this one pop, but that we will do in the next video otherwise, in the meanwhile, though, before we get there, If we head here to softwaretraining.co.za You guys will notice. We've got a variety of different Softwares we do cover. And you can also isolate your search on the top or right. If you do not, however, find the training videos you're looking for, just simply go.
