If you're having trouble finding element proof labels, rather than fuss with it, try alternative methods to ID the clutch. Such as small sign in front attached to the deck. I realize that's not a great description of what I have mind, but bear with me, I know what I mean... just cant say it... heh, heh. Anyway, I prefer the color code method. I've never had labels on any of my clutches or cleats. I have always referred to the color of the line. Just in case the crew member can't read. (but what if they're color blind, you say) yeah, well, I've only used the red line for port, green line for starboard deal for my two jib halyards... just so the foredeck guy can yell "GREEN!" or "RED!" to the winch operator in the cockpit. Works in theory, but rarely used... Since the boat isn't that big and you can see everything he's doing.
But the real reason color coding works well is that there's no translation needed. The skipper simply tells the guest to pull or release the red, blue, black, green, yellow, white(ugh) etc. line. If you say release the halyard, the guest's first comment will be "which one?"
