Sig problem

[themask70]

Couldn't really think of anywhere else to post this and everyone on the photography section has decent sigs, so, here's my problem:

Whenever I make a sig, in PhotoShop CS2, the end result is always really grainy, the final gif or jpg of the sig has no sharpness at all. I've tried putting up the resolution but that never makes any difference to the end result. If someone could help that would be great, cheers in advance

I don't have one atm (i'm assuming you mean the final sig image). I'm probanly not going to make one for a while lol. If you could tell me how you made yours, i.e. what starting size in photoshop and what dpi resolution that would be great because it looks pretty sharp. Thanks, i hope im not being too cheeky
