A positioning test strip: the edge of the screen to add localization test strip output.

   2, double-sided adhesive laminating: In the transparent medium (glass, acrylic, organic board) on both sides of double-sided adhesive laminating transparent (double-sided adhesive release paper fully transparent). First grating posted on the transparent medium.

   3, Lenticular picture right place: the lenticular sheet is placed on top of the screen (with the gate line side up, if it is membrane-lenticular lens sheet, first stick the transparent glass.), Raster image alignment:

  (1) Observation distance: 60cm distance beyond the observation screen.

  (2) direction bits: the 3d lenticular sheet material with the picture-side end of the test strip positioning alignment (all white or all black, the positioning of the test strip without breaking phenomenon). Accomplish this, which means that graphics and raster direction.

  (3) face up on the bit: First, the eyes placed on the horizontal center of the screen to observe the contents of the screen, to determine whether the screen displays "shear" phenomenon. If shear phenomenon, which means that although the lenticular sheet and painting

Face the same direction, but with a front view of the screen position is wrong. At this point, you should gently shift grating, until there is no shear phenomenon. Then, his eyes from the center of the screen to the left side of the screen pan, until the left end of the first

Shear point, remember the location. Also remember right the first shear point. If the center of the screen left and right positions relative symmetry, then the alignment is complete. If asymmetrical, gently pan lenticular sheet, in order to achieve

About two symmetrical positions relative to center of the screen.

   4, 3d lenticular printing image crop and fixed:

  (1) pressed dielectric plate with the picture, you can not have the slightest movement.

  (2) by 3d lenticular sheet edges to crop the picture (screen output generally stay out of about 3mm).

  (3) with a transparent adhesive tape (or cold film), the 3d lenticular lens sheet material and picture edges firmly fixed.

   5, Lenticular screen laminating:

  (A) 3d lenticular lens sheet material in the next screen in the last, into the cold laminating machine. Cold laminating machine roller should be uniform compression.

  (2) opened the first screen of the double-sided adhesive primer release paper, release paper cutting neat, uniform laminating a leader.

  (3) removal of the remaining three sides of the fixed transparent tape (or cold film), thrown off the double-sided adhesive release paper, laminating on the overall picture. Note junction processing, do not leave other traces of bubbles.

   6 Notes

  (A) formal output screen, the screen size should be slightly bigger (each side leaving 3mm).

  (2) should be uniform cold laminating machine roller compaction. The pressure is much greater than the pressure laminator kd board.

  (3) laminating process can not be pasted surface dust contamination. Laminating results, can not have bubbles.

  (4) to protect the lenticular sheet surface, do not have scratches.

  (5) After completion of the finished products must be in plastic bags or cold film release paper, the package to protect the raster image

The three conversion relationship

    (1 lpi) = 25.4 / (1 mm)

    (1pixel) = printer resolution (dpi) / (1 lpi)

   Lenticular lens material processed in factories, due to hot condensate containing the physical processes that lead to the actual factory  lenticular sheet pitch their nominal values ​​have a certain bias. Secondly, many types of printers or Press output accuracy can not achieve their desired accuracy. Will inevitably lead to the output lenticular lens graphics and raster imaging plate (especially when doing large picture) do not coincide. Therefore, the specific output Device (printer or printer) to test a particular lenticular sheet, with printed dots (print dot) Quantity pixel to represent. Thus, regardless of the nominal value of the grating plate factory big errors, the output device How much error, ensures raster imaging output screen with the grating exactly.
