Hello I'm looking to buy a pantone chart but if I don't want to spend that much money. I had a look on Amazon and I was wondering what is the difference between http://www.amazon.co.uk/Process-Color-Manual-Combinations-Prepress/dp/0811827577/ref=pd_bbs_4?ie=UTF8&s=books&qid=1198332071&sr=8-4 and this http://www.amazon.co.uk/Letraset-Pa...2?ie=UTF8&s=electronics&qid=1198332071&sr=8-2 Does the book have the exact colours that I will get when I print out my pantone colours? I have seen the used the Letraset pantone charts before and I was wondering if the book would have the same colours. Is it less expensive because it's a book, or am I just going completely in the wrong direction? Thanks Edit: I have a new 20inch iMac glossy screen. The glossy panel is better than most but being glossy its not as accurate as the earlier iMacs. I was wondering if its worth spending the money on a monitor calibrator such as this http://www.amazon.co.uk/Pantone-Huey-Pro-Monitor-Calibrator/dp/customer-reviews/B000OFC1YY/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1&customer-reviews.start=1&qid=1198332694&sr=8-3#customerReviews Is it even worth it if the screen I am using is glossy?
