"Gary Ryan has pointed out that illustrations of the ‚coarse' and ‚fine' prints (such as that given in Michel or Gibbons) are an oversimplification." I couldn't agree more.
I collect Austria but only to the extent that I have an album filled with Austrian stamps, not that I'm an expert on Austrian stamps. Nevertheless, for what it's worth, this "coarse vs. fine" print difference can be very misleading. Defined this way, you'd think there were two distinct varieties. But there aren't.
There would be two varieties if the stamps were printed at two distinctly different times (they weren't) from different plates (they weren't) with different inks (I don't think they were) or on different paper (they weren't). As the links in this thread explain, what actually happened is that over time, different rollers were used, some softer and some harder, and different underlayments were used beneath the stamps (some softer and some harder) and perhaps the amount of ink changed (completely unknowable) and the printing plates themselves may have gradually worn, and so on. So -- over time -- stamps printed from different rollers, etc. produced different degrees of "fineness" or "coarseness".
To simplify them, you could divide these stamps into two varieties, "fine" and "coarse," but really some are very fine, some moderately fine, some a little coarse, others more coarse, and so on. From "fine" vs. "coarse" there's a gradation from really fine to really coarse with many stamps in between, and it's as many as you decide there are depending on this whisker or this lock of hair, and so on. Feel free.
Today this wouldn't be allowed, but back then a stamp was a stamp and how sharply or not these stamps were printed may not have seemed like a big deal. A little surprising for Austria since they generally pay a lot of attention to the details. But maybe not on this issue.
So you don't have two varieties, coarse and fine, nor four varieties as it says somewhere. What you have is a gradation of stamps or a continuum that gets coarser over time, with the use of different rollers and maybe with other factors, too. Call them "fine" and "coarse" if you want, and that's a decent enough distinction to make, but remember that a lot of these stamps are neither. They may be exceptionally clear so "very fine" or fine on the way to becoming coarse or really coarse in a very obvious way -- or they're somewhere in between these.
If I were laying out an album page, I'd provide spaces for stamps that are crystal clear and well printed ("fine") -- and identical spaces for stamps that are much more coarse. And I'd leave it at that. And that's pretty much what Scott and many albums do. Collectors naturally ask is this stamp more "fine" or more "coarse"? The answer is you need to compare two identical stamps and decide. If your "coarse" stamp isn't coarse enough, maybe look for an even coarser stamp. If your "fine" stamp is just a little too coarse, look for one that's more fine.
But trying to put these stamps into two distinct piles of "fine" and "coarse" is just not going to work. There are no clear dividing lines between groups. So, depending on how many of these stamps you have, your "fine-to-coarse scale" may include just two or three or stamps. Or you may need six, seven, or eight stamps in your scale from really fine to really coarse. Both are correct. It just depends on how far you want to go.
As for my Austria album, I just mount the crispest and finest stamps in one place and the coarsest below them -- as s if they were two distinct printings. Which of course they weren't. I'm a busy man.
