Yoshiya,
No. There is no specification for the thickness of solder paste printing. You shall check by yourself to see the printing result is good or not. Basically you can measure the mean value and standard deviation to see it meet your requirement or not.You shall know the how much volume of solder paste will make good or poor solder. As recommendation that you shall choice the critical component to check the solder paste printing result.

I have 1 stencil with 4mils thickness and I´d like do test if it is good or not regarding solder paste transfer so, I must print 1 PCB and measure the solder paste height and volume. Special related with height, for example:
4 mils stencil must measure 3,5 mils to 4,5 mils . I just to know the spec (minimum and maximum variation)
