Can not be found or be used because this font belongs to Channel 4 in the UK. that Font is hard to find and get. If you want that font email and I can give it to you by free

Could you send it to me?

No probs, I'll have a look myself

Channel4 uses since 2005 the C4 font family designed exclusively for Channel4 by FontSmith.
