Comparison of RGB & CMYK Image Modes vs. PDF/X-1a

What is the purpose of this book? You look at it and say "why?" Well, as each page says - you can generally find an image which was saved as RGB (Red-Green-Blue) Mode and also as CMYK (Cyan-Magenta-Yellow-Black). Then, also, as each page says, that page was printed to Acrobat X1 Pro using the setting stated on the page, either PDF/X1-a:2001, PDF/X3:2002 or as a PDF High Quality Print from the Properties Settings when one chooses to print from MS-Word.The overall reason for this book is to visually see what the apparent differences are when CreateSpace prints a book which is created using the RGB and CMYK image modes in combination with the PDF settings selected. Hopefully this is helpful to somebody; I know it will be helpful for me.
