Re: Lenticular image frame rates

Every lenticular sheet has lines per inch and it's not the resolution as much as how the image is interlaced into left-eye lenticles and right-eye lenticles. I'm over simplifying it, but that's about it.

So you might have a sheet with 100 vertical lenticles--50 for each eye. Let's say your stereo photo is 1000 pixels wide and 1000 pixels long. Then each lenticle will expose 20 pixels wide by 1000 pixels long for each eye. For example, 1000/50=20 pixels. These 20 pixels are then interlaced left eye/right eye and so on to cover the 100 lenticles.

Now the printing machine has to also consider it's resolution, which is probably 300 pixels per inch, so the image needs to be converted to fit it's resolution as well. Pretty much like any ink-jet printer does. So you have a combination of actual image resolution vs. printer resolution, and there is probably a sweet spot for the best image without creating a lot of noise in the image.

Let me know if that's what you were asking...
