First step: the unit hologram quantity required according to layout makes the nickel plate of the unit hologram of requirement with electrocasting;

Second step: the nickel plate of the unit hologram of whole required splicings is accurately cut into the desired identical shaped and size of layout;

Third step: on the one side of smooth plastic bottom board, stick double faced adhesive tape;

The 4th step: the nickel plate of the unit hologram that will cut, by desired arrangement, be stitched together in the one side that double faced adhesive tape is arranged one by one, forming a matrix of being formed by the unit hologram, and reach size that holographic mother requires;

The 5th step: the vacant part around the unit hologram that is stitched together, stick the fringing nickel plate with the nickel plate stack pile of unit hologram, to form a frame;

The 6th step: will be add all good big versions of splicing of upper side frame by the matrix of a plurality of unit hologram, carry out repeated multiple times electroforming processing, with the seam of progressively filling and leading up and eliminate splicing with increase the bond strength of seam and eliminate the thickness difference of former each concatenation unit, finishing spliced nickel plate is exactly required holographic mother.

The thickness of nickel plate is at the 50-60 micron in the above-mentioned first step, the nickel plate thickness of slab error of each unit hologram is controlled at ± 5 microns within.

Cutting with precision optical machinery of the nickel plate of unit hologram sheared or the method for cross cutting in above-mentioned second step.

After sticking double faced adhesive tape on the one side of smooth plastic bottom board, intersect side at two of double faced adhesive tape and respectively stick a separate paper, in the above-mentioned third step with benchmark as the nickel plate of pasting the unit hologram.

The nickel plate of said units hologram be shaped as square or rectangular.

The invention has the beneficial effects as follows:

1, owing to is not subjected to the restriction of concatenation unit hologram size, the sliceable big master hologram that contains various unit sizes.Particularly be suitable for the splicing of large-size units hologram.

2, owing to adopting the method for on double faced adhesive tape, pasting to splice, so splicing speed is fast;

3, since concatenation unit cut precision can accomplish very high, therefore, the splicing precision also can accomplish very high.Seam be filled and led up and be eliminated to follow-up electroforming process can, is combined into an integral body, becomes a desirable big mother matrix.
