I don't understand why Finn could see the photo and I couldn't - even on my nice desktop Mac.
I think it would be great if somebody would sell scribed styrene decking in 1/700, but to my knowledge nobody does. The finest I've bumped into is Evergreen's, which goes down to .025" spacing. That's mighty small - 8 1/2" on 1/350 scale, or 17" on 1/700. ( www.evergreenscalemodels.com/Sheets.htm )
I've always had my doubts about decks printed on sheets of wood. As GMorrison pointed out, there's room for doubt about whether it actually looks like miniature wood, because of the grain pattern. On the other hand, some of the photos of those printed sheets do look mighty impressive.
The bottom line is that the best way to reproduce a planked deck is to lay individual planks. The late, great Donald McNarry did it on scales down to at least 1/32"=1' or 1/384 ( www.donaldmcnarryshipmodels.com/26.html ). He used fine holly shavings taken from a plane, cut to width and length with a razor blade. If I remember right, when he was a younger man (with young eyesight) he did some warships and liners with individual scale planks on 1/600 scale. I suggest, though, that we mere mortals learn to be satisfied with what's currently available - which is pretty daggone good. And maybe, sometime fairly soon, one of the kit manufacturers will produce something even better. Take a close look at the Tamiya Missouri, or the Trumpeter Queen Elizabeth, both in 1/700. They sure impress me.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
