What is a fly’s eye sheet? A fly’s eye lens is called fly’s eye because it is how a fly sees his environment. It is a sheet of plastic embossed with a lens array on the surface. The lens array is not a linear lens array like lenticular, but round lenses, nested together in a honeycomb. We use a honeycomb because it is natures most efficient way of packing spheres together.
Is this new? Yes and no. Scientists have studied this as far back as the 1800‘s, producing prototypes using glass rods, with curved surfaces on one end to understand how the fly’s eyes work. Lippmann was the first to invent “Integral Photography” in 1908 using an array of lenses, but he did not use a true hexagonal lens array, but instead an array of individual lenses. See this page for more information about the history of lenticular and 3D Integral autostereoscopic methods. The first true hex arrays (as a single sheet of material) appeared in the late 40’s to early 50’s. They were primarily made from glass. The most common method of making them back then was to create a mold using thousands of ball bearings, packed together in a hexagonal array. Plastic hex arrays became available on a very limited basis in the 70’s. They were small arrays, and primarily injection molded, or compression molded.
Some fly’s eye lens arrays were produced using UV clear resin, printed as droplets onto a plastic sheet to create the lens array.
Then more recently, plastic sheet extruders began to emboss fly’s eye lens arrays into their sheeting and selling these products.
What does MicroLux™ bring compared to other fly’s eye sheets? MicroLux™ is a true hexagonal packing of spherical lenses, allowing for 99.9% fill factor. This means that there is essentially no space on our sheet that is not curved lens surface. Printed lens arrays and competitive embossed products I have seen have significant space between lenses or are square packed arrays, meaning there is a small diamond shaped area between every 4 lenses that is not effectively magnifying, and thus the 3D effects are not as brilliant.
Forward Optics developed a unique proprietary engraving process and design to perfectly nest the lenses in the hexagonal arrangement, where the lenses meet each other perfectly to achieve this fill factor.
How is MicroLux™ produced? It is an extrusion process, where the cylinder engraved with the negative hexagonal lens pattern is pressed into the molten plastic, embossing the lens array into the plastic material, and then the edges are trimmed off and it is cut to the desired length. Just like the usual lenticular sheets!
Again, the answer is yes and no. Forward Optics produces using both methods, depending on the customer and application. MicroLux™ has the advantage of the 99.9% fill factor, meaning there is no dead space and the resulting 3D has the optimum contrast, whereas the printed lenses have some space between them, which reduces the contrast.
On the other hand, printed lenses have the advantage of be applied selectively, meaning you can have lenses where you want and not have lenses where you want. With the embossed lenses, the lenses are across the entire surface of the sheet.
Why would printers use MicroLux™? MicroLux™ offers two primary benefits; first, it is very easy to print, registration is very forgiving, and if the proper checks are made during the design and plating process, it yields good product immediately and second, MicroLux™ offers any plastic printer the ability to print 3D effects without a long learning curve and even without software.
Why would advertisers use MicroLux™? MicroLux™ offers a wow factor, drawing the attention of consumers, who are compelled to stare at the 3D effects and are amazed at the depth they see. Also, because it is generally easier to create and print, it is generally not expensive to produce.
Is MicroLux™ recycleable? It is pure APET or PolyPropylene, meeting those recyclable designations.
Did you send sample sheets for lab tests ? We have significant lab data showing compliance with every regulation in Europe.
Why did DP Lenticular decide to add MicroLux™ to its product list?
We are always interested in new products and new technologies.
We don’t consider the fly’s eye effect as a new product but MicroLux™ brings a higher quality with a 99.9% fill factor. We also believe that you can print similar effects on a usual lenticular sheet but our goal is to concentrate on a new opportunity: printing volume 3D Integral images. This means real 3D images that you can see moving the card in all directions (360°). This is something new in the 3D printing business.
