I'm designing a lenticular sticker to promote an album. I'm confused about certain fundamental aspects of the artwork preparation. I understand that I need to provide a distinct layer/image for each 'frame' of my lenticular image. However, I understand that one can have anywhere from 2 frames to 10 or more in one's lenticular image.
Question 1: What are the tradeoffs between few frames vs many frames?
I understand that many frames can result in a smoother frame-to-frame transition -- a smoother animation or a more realistic 3d effect -- but it seems to me that this smoothness may be achieved at the expense of sharpness or acuity. The printed image will be 300 dpi, regardless of how many frames. Therefore, more frames will mean fewer pixels per frame.
Question 2: Does it cost more to print more frames in my lenticular image?
It'll certainly require more design effort on my part to create 10 frames vs 2. Does it cost more to print one with 10 frames than with 2? Are there other tradeoffs?
Question 3: If I'm depicting a 3d object, how much rotation between frames?
I'd like my lenticular image to show a human figure from 3 (or more) different angles as you rotate it left-to-right. If you look directly at the sticker, you'd see the figure straight on. If you rotate it left or right, you'd see the same figure but slightly to one side. I realize that many frames means less rotation from one frame to the next. If I only had 3 frames in my lenticular image, how much should i rotate the figure between frames? 15 degrees? 30 degrees? Ideally, I'd like the figure in my image to rotate, on average, just exactly as much as the viewer rotates the card to see the different images.
Any advice or detail about how to design for lenticular stickers would be much appreciated. I'm prepared to make ten distinct images of my figure, each from a slightly different angle, if necessary. That said, I'd hate to go thru all the trouble if it will make a lousy image.
