(Okay, the title’s a lie. This started out “quick” and spiraled out of control. I’d say I’m sorry, but really I’m not.)

On Sunday, Japanese telecom giant NTT announced plans to expand their e-manga business into North America. Initially, this sounds like a great idea, but when you get to the details, there’re a few flaws. I’ll just cover the most obvious ones as they pertain to the Barnes & Noble nook reader, as that’s the one I have– you’ll quickly see that the issues are more or less universal.

The biggest issue is the size difference. The standard, traditionally-accepted size for manga volumes in North America is 5 inches wide by 7.5 inches tall, giving a surface area of 37.5 square inches. The nook’s main screen is 3.5 inches wide by 4.75 inches tall, giving a surface area of 16.625 inches– only 44.33% of the paperback’s space; margins notwithstanding. This also doesn’t get into the issues of resolution, though in reality the resolution of the nook’s e-ink screen is far more than sufficient for manga. The size becomes a deal-breaker because the two most prominent e-book readers– the nook and Amazon’s Kindle line– don’t offer any kind of zoom functionality.

The size issue poses another problem; even if the images were to be resized so that it could be clearly readable in the adjusted speech bubbles, the image would still be distorted. The standard paper-bound manga has an aspect ratio of 2:3, while the nook’s screen has a ratio of 14:19– just slightly too short. Increasing the vertical size of the e-ink screen to 5.25 inches would solve this; if that were to happen, the device would need to be lengthened, or the color touchscreen (the nook’s defining feature) would have to be downsized or eliminated. In my opinion, neither option is feasible.

A slightly odd issue is the fact that manga is read right-to-left; most e-readers use a right-facing arrow to advance the page, and start with the left-most page. It’d be a tricky thing to program, I think, but it’s hardly a deal-breaker– just a matter of retraining, as it was when right-to-left manga was introduced to begin with.

Finally, there comes the issue of the logical size of a manga volume. My sample “standard” manga is volume 13 of Hayate the Combat Butler, which has 187 pages of actual content (about another 5 pages or so at the end– the leftmost end– are used for advertising and promotions). Even in monochrome, a high-resolution scan of one of those pages, uncompressed at 400 DPI, is 1.83 kilobytes. Doesn’t sound like much, does it? The full book is therefore 342 kilobytes. Slightly larger than an average text e-book of that length (I picked Coraline as my exemplar, at 323 kilobytes). Assume that the metadata and formatting for the e-book is negligible compared to the space needed for the content. Let’s now assume that the e-book is in 16-bit greyscale, and each page can be compressed by about 33%. Doing this changes the size of each image to 19.34 kilobytes, bumping the size of the full volume to a whopping 3.53 megabytes! In contrast, Quicksilver, a text e-book that is 927 pages in its print form (its very small-print print form it should be noted), is only 1.29 megabytes. Granted, these days that still doesn’t sound like a lot– unless you’re the one footing the bill for the data transmission charges on the 3G cellular networks that feed these devices. (Consumers don’t, it should be noted, or at least don’t directly pay the costs; they’re usually lumped into the cost of the e-book.)

It’s a sad thing to say, but I think e-manga is more or less dead in the water right now until the devices can support it better and data charges are brought down out of the ludicrously high levels that they are now. A firmware patch for the devices could solve that issue (at least giving zoom and RTL reading functionality a green light), and it’s a given that data will become as cheap as– well, let’s say basic bottled water– at some point. I’d probably estimate about three years for the tech to be ready (as a stupidly out-there outside guess)… but the market’s here now, I think. I wish NTT best of luck, but it’s gonna be a while ’till this really catches fire.
