Construction Images are interlaced on the substrateĮach image is arranged (slicing) into strips, which are then interlaced with one or more similarly arranged images (splicing). Lenticular images saw a surge in popularity in the first decade of the 21st century, appearing on the cover of the May 2006 issue of Rolling Stone, trading cards, sports posters, and signs in stores that help to attract buyers. Lithographic lenticular printing allows for the flat side of the lenticular sheet to have ink placed directly onto the lens, while high-resolution photographic lenticulars typically have the image laminated to the lens. While PETG and APET are the most common, other materials are becoming popular to accommodate outdoor use and special forming due to the increasing use of lenticular images on items such as gift cards. There are many commercial processes in the manufacture of lenticular images, which can be made from PVC, APET, acrylic, and PETG, as well as other materials. Other effects, like morphs, motion, and zooms work better (with less ghosting or latent effects) in top-to-bottom orientation, but can be achieved in both orientations. 3D effects can be achieved only in a lateral (side-by-side) orientation, as each of the viewer's eyes must see them from a slightly different angle to achieve the stereoscopic effect. Alternatively, several images of the same object, taken from slightly different angles, can be used to create a lenticular print with a stereoscopic 3D effect. Though normally produced in sheet form by interlacing simple images or colors throughout the artwork, lenticular images can also be created in roll form with 3D effects or multi-color changes. If a sequence of images is used, it can even show a short animation. The combined lenticular print shows two or more images by changing the angle from which the print is viewed. When printing on the backside of the lens, the critical registration of the fine "slices" of interlaced images must be absolutely correct during the lithographic or screen printing process to avoid "ghosting" and poor image definition. The interlaced image may be printed directly on the back (smooth side) of the lens, or on a substrate (ideally a synthetic paper) which is laminated to the lens. It's important to keep in mind that all interlacing methods necessitate an understanding of the accurate lens pitch, which can be determined through a pitch test. It's worth noting that this online tool comes with a size limitation, typically supporting images up to 12 inches in size. Additionally, there are commercial software solutions available for interlacing, some of which are free while others require a purchase.įor those looking for an online solution, platforms like ViCGI, a company specializing in lenticular printing and providing various tutorials, offer an online interlacing app. When these frames are combined, they form an interlaced image. You can achieve interlacing using Photoshop by generating masks for individual frames to obscure others. Once the images are collected, they are arranged in individual frame files, then digitally combined into a single file in a process called interlacing. It can be used to create frames of animation, for a motion effect offsetting the various layers at different increments, for a 3D effect or simply to show sets of alternative images that appear to transform into each other. Lenticular printing is a multi-step process which consists of creating a lenticular image from at least two images, and placing it behind a lenticular lens. ![]() Principle of operation of an animated or 3D lenticular print, showing repetition of views Creation and interlacing of images ( July 2023) ( Learn how and when to remove this template message) Unsourced material may be challenged and removed.
