First、Be sure
    Method, bright nanometer leads tabula rasa but is sure arbitrarily. Cut eager implement carpenter saw bit machine , average sculpturing machine , laser sculpturing machine in general available etc. , the best being in progress among them with laser sculpturing machine being sure to lead glossy result.

Second、Polishing
    The sheet material using laser to carve machine work carries out polishing unnecessarily. Use the sheet material that carpenter saw bit machine and the average sculpturing machine process to need treatment and polishing carrying out a cut.

    Step one: The levelling being in progress to the cut with art designer knife is handled , is scrapes cutting the crumbs powder staying when eager, and is slicks kerf.
   Step two: Use glazing machine or flame gun to carry out polishing on the cut , to demand glossy levelling of cut , not to have the obvious cockles or kerf.

Third、Test
    Step one: A fluorescent tube is set free the fluorescent tube joins in using silver plating reflection of light film (or reflection of light paper) to envelop on both side of leading tabula rasa, with two-sided bonding living. 
    Step two: Use silver plating adhesive tape seals up lead light to pull a long other edge mouth.
    Step three: Will lead tabula rasa lying horizontally on the reflection of light paper putting down shop; Connect up the fluorescent tube power source , preheat 10 minutes or so (long effect of time is nicer).
    Step four: Use naked eye or illuminometer to equal but perceive to lead tabula rasa's to lead the radiance and degree of homogeneity.

Matters needing attention
    1, leads tabula rasa avoiding a bruise in cutting the completeness being sure , needing to keep wrapping paper time polishing.
   2, leads tabula rasa polishing if whose cut being left over crumbs is last or dust , the meeting affect obviously to lead glossy result.
   3、The effect reflecting light at the back packing , leading if with fluorescent tube entirety up is nicer.
   4、Set the lead the tabula rasa length being equal to the fluorescent tube in the length best or brief strong point on one side of the fluorescent tube free; The adhesive tape also applying a silver plating if the fluorescent tube is obvious shorter than leading tabula rasa , the person comes into a part when testing seals edge mouth.
    5、Suggest using the true illuminant when testing; The meeting also affects illuminant brightness and colour leading glossy result.
   6、Use naked eye decision is just bright lead light directly unnatural leading a radiance may produce bigger deviation. The raw material leading tabula rasa because of method is bright is transparent enter port expecting that MMA , sheet material are colourless accurate , there is no background color when giving out light, naked eye unable direct perception whose true brightness , suggestion use illuminometer to test or having readjusted oneself to a certain extent lamp case movie deciding whose brightness.
  7、Use illuminometer the testing , the suggestion departure to lead tabula rasa 3-5CM.
