Lenticular prints stand out from the crowd and can be used to give prints the illusion of flipping or morphing from one image to another, seeming to be in 3D, zooming or looking like an animation.
But with these specialised effects, achieved through the use of special profiled plastic lenses, comes the need for quality and precise artwork, delivered according to what we know gives an optimum finish.
At the beginning of any lenticular project we strongly recommend initial ideas or images be supplied to Reflex so that we can offer advice on any potential problem areas and as well as potential improvements to your ideas that will ensure the final product is the best quality and performance. The guide below also explains key design points.
Ideally, we want your original artwork supplied in Indesign or Illustrator format, while Photoshop or pdf’s will work in some instances. Any scans and illustrations placed need to be supplied and converted to CMYK. Where possible, please outline fonts and if this is not an option, please make sure all fonts are supplied.
When supplying artwork for a simple flip, animation or morphs, a minimum 3mm bleed is required.
Any 3D projects require at least 3mm bleed top and bottom and around 10-15% of the entire width. This is to account for the parallax movement in the foreground and background elements.
If supplying video footage, .mov or .avi files in high definition are required – please get in touch for further advice if you are unsure about this.
Artwork should be set up to the final output or estimated size. All scans and images for any rastered/continuous-tone images should be at 300dpi minimum, with any placed within the document set at 100% or less so that they do not affect the resolution of the image. Above A3 size 150dpi is acceptable.
Spot colours can be used for flip lenticular but are dealt with as greyscale outputs. They can also be used as a static part of a 3D image but not part of the actual 3D image
If there are cutter guides in the job please make sure they are set up as spot colours and are clearly marked.
Any images that appear to be obscured by other layers will need to be supplied complete. Even though layers higher up in the order may cover missing elements on lower layers, these layers may become visible as 3D projects move.
Small copy and thin lines will tend to break up under the lens – a sample of the lens being used can be sent to you to check this if needed.
For flip lenticulars we recommend having the images flipping from top to bottom as this performs best with the lens parallel to the eyes. We suggest using two images and avoiding contrasting colours for maximum effect. Where possible, areas of white and light colour need to have similar colour areas on the opposing image. It is also good practice to steer away from hard lines and vector elements where possible
Any 3D project will have to move left to right as the light refraction from the lens sends different angled light/images to each eye which gives the illusion of depth.
When producing morph lenticulars we require only two images as we produce the additional ones with our own software. To ensure the best possible morphing effect the two images should, where possible, occupy a similar shape and contour.
Animations can work very well and have the similar rules to the standard flip – so avoid big contrasting colours and have some sort of texture in the background to try and hide the ghosting.
If you can have an image that loops this can provide the best result as there is no start or end to the motion which gives a nice effect. We can produce animation from HD footage but this will depend on the size and lens used – please ask for more details if needed.
Thank you for the A5 window stickers this week, they looked great!
