Lenticular Technology, How it Works and Care
Lenticular printing is a technology in which lenticular lenses (a technology that is also used for 3D displays) are used to produce printed images with an illusion of depth, or the ability to change or move as the image is viewed from different angles.
Examples of lenticular printing include prizes given in some snack boxes that showed flip and animation effects such as winking eyes, and modern advertising graphics that change their message depending on the viewing angle. This technology was created in the 1940s but has evolved in recent years to show more motion and increased depth.
The lenticular effect used in Louis Markoya limited editions is stereoscopic or 3D Lenticular. The method to produce these works starts with an original oil painting by Louis Markoya. This is photographed in very high resolution and the file is carefully examined by the artist to ensure no defects and color consistency, etc. All dust marks, scratches, and brush hairs that appear in the original are removed and the file set aside. A new copy of the perfected digital file is made and in this file Louis must designate where in depth (or the “Z” plane) each element of the picture will fall within the process. This file is used to generate a depth file utilizing very specialized software. The software sets left/right eye separations for the stereoscopic view. A second program converts the left right eye perspective views into strips which will fall below the curved lenses of the lenticular sheet. The diagram below explains how the curved lens separates the left/right views and allows the viewer to see a 3D image on a relatively flat surface. Once the image is printed the lensed sheet must be carefully aligned to the printed strips and cold laminated.
The example shows only 2 (left and right eye perspective) strips under each lens, but in reality your Louis Markoya 3D Lenticular print utilizes the latest lenticular technology which utilizes 6-8 left-right eye pairs under each vertical lenticular lens.
Care and Cleaning
Your limited edition print has been printed with the very latest in archival inks. D o not hang the print in direct sunlight. It is advisable not to touch the lens surface, but you may occasionally need to clean it. Many common household cleaners may be harmful to the materials used in the lenticular lens. The best safe cleaner for this material is to use grain alcohol or a good quality vodka. Lightly moisten a soft lint free cloth with vodka(or grain alcohol) and wipe the surface gently in the direction of the lens (up and down).
