印刷廠對立體印刷的分類3.點陣式光柵立體(變畫)印刷【步殼印刷】


點陣式光柵與柱面鏡光柵不同,是由很多的小透鏡按行和列排列組成,如同印刷的網點一般,因此又稱為鷹眼光柵。組成這種光柵的透鏡形狀可以是球面鏡,也可以是圓錐或多邊形,每一個透鏡可以在各個方向對光進行折射,而不是像柱面鏡那樣只在一個方向,因此可以在多個方向實現變圖的效果

由於點陣式光柵在各個方向的折射是相同的,而立體視覺的視差僅在水平方向,因此點陣式光柵成像會對立體視覺產生乾擾,一般僅適合製作變圖效果。點陣式光柵對製作的要求更高,要將圖像按像素處理(而不是目前的分條處理),難度較大,並且光柵全部進口,價格比較昂貴,因此目前國內應用還很少
