Wow - i didn't think i'd get much response on this topic.
Making pdfs from images on this site is pretty easy. I do it all the time for Star Trek. I print using 280gsm A4 photo paper (i get about 70 sheets for $30 AUD), and 9 cards per sheet. The resolution of the final print is marginally less than a high-res pdf. The text on the card is very easy to read.
In the end, you probably don't want the printable cards to look too good, because you probably want to encourage new players to make an effort to find real versions of them.
The issue is creating an organised play circuit that is accessable to new players. Movie block might work, but there are large chunks of cards that are very hard to obtain, making an unfair playing field. As for FoTR block, it is just one set RotEL that they need to get, and if we can help with printable proxies, it may aid new players getting into the game.
I suggest that movie block is left for advance players, with no printable proxies. Printable proxies could be allowed for FotR block only, and for whatever cards (be it starter decks, or selected cards from RotEL or whatever).
I will make up a pdf from images on this site and get it to you kenddrick for the website.
As for legalities ?? Ideally it would be nice to obtain permission from Decipher, but we are not having too much success moving forward with this. I don't think random players printing proxies if going to incur the wrath of Decipher - how will they track it?
