In printed images we all must have seen animation such as dancing images, changing graphics; winking of eyes that are commonly considered as 3D effects but in reality, it is the lenticular effect. This effect is nothing but, in reality, it is a specialized image that is created with the help of a specialized printing process known as lenticular Printing, and lenticular sheets or Lenticular Lens is the substrate that is used in the process. soft lenticular sticker is majorly found in children's toys but in today’s time, collection lenticular lens is finding application in numerous areas too. Types of lenticular prints Stereoscopic effects: In this case, the change in viewing angle has to be very small so that each eye can see a slightly different view. The 3D effect is created without any need for special glasses. There are various designs of soft lenticular tpu printing. Different lenticular lens designs are present depending on the sort of animation and the printing process that are used to produce the lenticular prints. There is a difference in the thickness and viewing angle of the lenticular. It is also seen that angle of lenticular is also different. Flip effect Transforming prints: Here there is the use of two or more very different pictures and to switch from one image to another there is a need for the lenses to be designed in such a way that it can provide a relatively large change in angle of view. This way viewers can easily see the original images. Animated prints: In this case the distance between different angles of view is medium. It is so that when both eyes see the same picture, by moving a little bit you can switch to the next picture in the series. Generally, sequential images can be used but that too with only small differences between each image and the next. Design of Lens There are different designs for the lenticular lens. There is the existence of various lenticular lenses but all depends on the sort of animation and the printing process to be used to produce the soft lenticular sticker China. It is found that the angle of lenticular differs a lot. For an animation effect, a wide-angle will work best and a narrow-angle is required for giving an optimal 3D effect.

In today’s era, you will find that hundreds even thousands of advertising messages knock your head and try to gain access to the part of your brain that decides to purchase things. Keeping so much money at stake, it is quite surprising to see that to catch our attention advertisers go to such extraordinary lengths. Here the only problem is our brains habituate as they get used to seeing the same kind of thing over and over again. So to stay one step ahead the advertisers need to find new tricks. One of their new ideas is to print lenticular product, images on magazines, book covers, and posters that seem to change with your moving head. Let's see how they work. Lenticular Sheet/Lens Lenticular lenses are the piece of extruded plastic sheets that on the front surface of the material have repeating rows of convex lenses (lenticular), and on the backside of the material, it has a flat surface. It can either be directly printed or can have a pre-printed graphic mounted to it (depending on the process of printing). Lenticular Printing Lenticular printing is a specialized printing process that makes use of a combination of specially prepared graphics that are specifically made to perfectly work together along with lenticular product China so that it can create printed images that either has the illusion of depth or the ability to change or move when the image is viewed from different angles. Interlacing is the process that makes graphics that can be used with a lenticular lens. Interlacing is also a process that creates a lenticular image from a set of 2D images. From each 2D image, a small strip is taken and to match a specific lens pitch it is combined in one image. With repeating slices of multiple images an interlaced image is made that can be multiple views of one scene for 3D or multiple frames of an animated or multi-image sequence. The interlacing of these divided strips is performed together. To work effectively the interlaced image is then printed in register (perfectly alignment) underneath the lenticular lens. lenticular product manufacturers are also available that provide you good quality products.
