Subtitles of the Movie (Adobe Photoshop 7 / Saving/Printing / EPS Format)
Choosing the correct image file format is largely determined by what you plan to do with this particular image. And in the next few lessons, I want to talk about some of these different formats and what their advantages are. With my multi-layered document, notice I have the option to save out all these different formats. In the older versions of Photoshop, if I had a multi-layered document, I would only be allowed to save in a format that supported my layers, in this case it would have only allowed me to save as Photoshop. But in later versions of Photoshop, and in this version obviously, I can choose to save out a version to any of these formats and Photoshop will change the image accordingly. Such as collapse all my layers together into one particular image file. I'm going to cancel for now, and talk about a very popular workflow. Let's say this image was designed for inclusion in a page layout program which would eventually be printed in an offset press. Well what am I to do, is convert this to CMYK. And so, what I am going to do with my document here is I'm going to go to the image menu and choose duplicate, and I'm going to merge all my layers, and here is my duplicated merged layered document. And from the image menu, I'm going to choose mode>CMYK. So, I'm going to convert my RGB document into CMYK. And you may have noticed that some of my bright blue areas here got a little bit less saturated since they really cannot be reproduced in the smaller CMYK color gamut. Well, now I have a CMYK document. So I'm going to go to my file menu and choose save as. And I'm going to save this one as an EPS file. Now the EPS format, which stands for encapsulated postscript format, is a very popular format, which most page layout applications can support. And a notice what some of the warnings that I'm getting here. Since I've saved this before, it's going to ask me to save it as a copy. So it's going to add the word copy here. And what I might do is replaced this with a suffix .eps, because I always add a suffix or the file format suffix name to the end of the file name. Because, this is a little bit easier to understand what the format is when you are looking at a bunch of files in a folder. But also, it makes it eminently interchangeable with a windows computer. And I have a special folder that I am saving all these files, and to talk about different things such as file size when things are compressed. I'm also going to embed the CMYK ICC profile, designed for the US web coated or the standard web offset press. So when you go ahead and say yes to the EPS format, it brings up this dialogue box asking you to make some further decisions on some formatting options. One of my options is to include a preview, and if I am only going to work in a Macintosh environment, I might choose Macintosh 8-bit preview. But if I'm going to transfer this, or I know this might be used on a windows computer, I might choose a TIFF preview. Now adding a preview is very helpful, because it allows people to see sort of the low res version of my image. And you can see it's going to create 8-bit version. So the color won't look very good in the preview, but it's just a special file attached to the full color image. And of course, this preview is used just for placing and moving around in a page layout application. And you can choose different encoding types. Binary is a little bit more modern, and usually works with most image or page layout applications and rips. Or if you have to, you can also choose the ASCII format which is a little bit older form of coding, and creates larger files, but also works fine. If you wish, you could also include the half-tone screen information and transfer information, which has to with the way the inks would be generated for this. However, most output devices, such as the rip that will generate the films for your printing, will include this information automatically. So I'm going to choose not to enable that. If you enable image interpolation, it will anti-alias the printed appearance of the low-res preview. So you might want to do that. And now, I can hand off that file, the EPS file, to someone working with a page layout application that needs to include that in their document.
