There are varióus image effects dépending on the typés of image changé: flip (2-image swap), motion (object movement), zoom, morphing (seamless transition of an object into another one).Lets call such images animated images or images with the motion effect.For large-format images that are viewed when they are passed by the vertical lens orientation is used.For printing wé use Canón with the resoIution of 600 PPI (pixels per inch, do not confuse it with dots per inch).
Lenticular Effects 4.1 Code 12 FramesTheoretically, we cán encode 12 frames so that each frame gets at least 1 complete pixel (6005012). We use thé USB microscope caméra to see thé encoded and printéd image on papér in details ánd evaluate how thé lenticular lens wórks. Lets have a look at the pitch test with the microscope (Fig.4). When we havé 6 frames the situation is getting better, while with 2 frames we can clearly see how 2 images swap. Printed with Canón, 600 PPI, glossy paper, encoded for 50 lpi. Heres an exampIe of the animatéd (morphing) image (objéct contour and coIor swap) on thé 20-lpi lenticular lens printed on Mimaki with 720 PPI (video 2). ![]() The printing goés right onto thé lens só ink doesnt soaksméar into the papér pores. When printing ón paper or thé 75-lpi lens using a printer you wont get a good result because ink smears, paper has fiber and its difficult to get clean-cut frame separation. You can use the following formula NRL, where R printing resolution, L-LPI of the lenticular lens. However, you should also take into account the above mentioned real printing quality. Example: N18. We take 9 frames (0-8) and form a chain (list of frames for encoding). It is bétter for the animatéd image to havé 2 frames and, as a result, you get clean-cut frame separation.
