Lesson 6, "Dimensional Adjustments" begins with a discussion of how the resolution requirements for specific screening outputs will affect the resolution of your images. This is followed up by making linear and dimensional adjustments, cropping and re-sampling images and working with vectors as Smart Objects.
Lesson 7, "Assigning and Creating Colors" shows you that to get accurate color in prepress, you will need to get in to Pantone swatch books. Here you will learn all about Pantone, the process of assigning and building process colors, assigning spot colors, and matching colors from Photoshop to other applications.
Lesson 8, "Correcting and Adjusting Grayscale Images" begins by evaluating an image to find out where the important parts of the image are. Here you will examine tonal regions, work with histograms, curves, and the info palette. Then you will work with an image adjustment layer to set highlights, shadows, adjust brightness and contrast, as well as make adjustments for newsprint and dot gain.
Lesson 9, "Correcting and Adjusting Color Images" now applies some of the same techniques learned with black-and-white to your color images. Whereas the last lesson worked with one channel, now you will apply your knowledge to multiple channels.
Lesson 10, "Image Editing" focuses on what needs to be adjusted for prepress output. The topics here include JPEG posterization, the removal of dust and scratches, image sharpening, creating silhouettes, and adding type to images.
Lesson 11, "Mode Conversions and Color Separations" asks the question: if you want to print in grayscale, should you capture in grayscale or capture in color? Here the instructor shows you how to convert between modes such as RGB to grayscale, RGB to CMYK as well as creating custom CMYK profiles.
Lesson 12, "Output" is all about putting your image into some other format. To output to other formats reliably you should know about these target formats (TIFF, EPS, PDF, DCS) and the programs that will use them.
Lesson 13, "Automation" will show you how to streamline your efforts by creating actions within Photoshop. As was said at the beginning, this is all about efficiency and how to get things done without being bogged down. By using actions you can automate many of the routine tasks and get back out to doing what you would rather be doing; shooting pictures.
