Defects in the way the lenticular lens is cut lead to phase errors between the lens and the image.
Two examples, taken from the same production batch:
The first image shows a cut which removed about 150 µm of the first lens, and which shows irregular cutting of the lenticular lenses. The second image shows a cut which removed about 30 µm of the first lens. Defects in cutting such as these lead to a serious phase problem. In the printing press the image being printed is aligned relative to the edges of the sheet of material. If the sheet is not always cut in the same place relative to the first lenticule, a phase error is introduced between the lenses and the image slices.
Famous quotes containing the words defects and/or cutting:
“We often make use of envenomed praise, that reveals on the rebound, as it were, defects in those praised which we dare not expose any other way.”
—François, Duc De La Rochefoucauld (16131680)
“Simply because our times are complex, does it follow that our parenting must also be? Must we reject the common sense that what worked so well in the past just because our times are high-tech? We live in such fear of being called old-fashioned that we are cutting ourselves off from that which is proven.”
—Fred G. Gosman (20th century)
