Research conducted at Curtin University in Perth has enabled significant increases in image quality in a widely used 3D printing technique that is more than 100 years old.
Anaglyph printing — think of the red-and-blue 3D glasses used to transform 2D images to 3D images in comics, magazines, books, and newspapers — came into being when the continuous-tone printed anaglyph was invented by French physicist Louis Ducos du Hauron in 1891.
The technique works by combining the left and right images of a stereoscopic image pair into the red and blue color channels of the output anaglyph image. With the red/blue 3D glasses, the left eye sees only the red channel of the anaglyph image, and the right sees only sees the blue. If the anaglyph 3D image has been constructed correctly, the viewer sees a pleasing 3D image on the printed page.
The project team, led by Curtin research engineer Andrew Woods, targeted crosstalk problems which are visible as ghost-like shadows. Their paper published recently in the SPIE journal Optical Engineering details seven recommendations for overcoming crosstalk.
“The largest reduction in crosstalk is likely be achieved by using inks which have a better spectral purity than current process inks used in color printers,” Woods said. “We found that an 80% reduction in crosstalk was potentially achievable just by changing the cyan ink.”
The anaglyph technique is easy to implement and the anaglyph 3D glasses are relatively cheap, so the technique is used very widely, Woods said.
However, printed anaglyph images often suffer from a number of image quality limitations. When the 3D image is viewed through the colored glasses, there is often a significant amount of crosstalk (or ghosting), an undesirable property of some 3D techniques whereby the left eye sees some of the image intended for only the right eye, and vice-versa. Crosstalk is usually visible as ghost-like shadows throughout the image. If crosstalk levels are too high, the quality of the 3D experience can be significantly reduced.
“The printed anaglyph is 121 years old, but this appears to be the first time that a detailed technical simulation of crosstalk in printed anaglyphs has been developed,” Woods said. “We started by measuring the spectral characteristics of various printing inks, 3D glasses, light sources, and papers. From there we developed a simulation which models the viewing of an anaglyph 3D image, and subsequently performed an experiment to validate the accuracy of the model. We hope this work will help provide a 21st-century improvement to the 19th-century invention.”
