The lenticular sheet pitch is the width of the lenticular lens sheet line. The nominal lenticular sheet pitch There are many ways, useful for raster width mm mm to the nominal (common in domestic light board), but also the nominal lenticular sheet density lpi (common in import raster). Include the use of photo machine or a printer to print dot pixel nominal.

 The three conversion relationship:
 (1 lpi) = 25.4 / (1 mm)
 (1pixel) = printer resolution (dpi) / (1 lpi)

 Raster processed in factories, since the hot condensate containing the physical process that leads to the actual lenticular sheet pitch with a certain bias nominal factory. Secondly, many types of printers or printer output accuracy can not achieve their desired accuracy. Will inevitably lead to the output raster graphics and raster imaging plate (especially when doing large picture) do not coincide. Therefore, the particular output device (printer or printing) on the test a specific raster, with printing dot (printing dot) to represent the number of pixel. Thus, regardless of the nominal value of the lenticular sheet plate factory how much error, how the error of the output device, ensures raster imaging output screen with the lenticular sheet plate exactly.

3d lenticular sheet pitch relationship with the viewing distance:
 Different pitch 3d lenticular (lenticular) image, the refraction lens reflex arc distance is different, it is necessary to show a viewing distance of the best results. Specific parameters are as follows:
