Camera Calibration Grid on Acrylic

Hi All,

 

I will have a laser pattern on a frosted acrylic sheet (6 mm thick). I will be measuring this laser pattern through this acrylic sheet with a camera and machine vision application. I need to calibrate this camera. I am going to use a dot grid on the acrylic sheet to calibrate the camera. However, I am having trouble finding a resource to print this simple dot grid on the acrylic sheet (black dots for high contrast vs the white translucent frosted acrylic sheet). I have found companies that print on acrylic, but all are for portraits, etc., none for engineering applications, and thus their tolerances are very poor, and as you know I need this dot grid to be near-exact. 

 

Question: Have you printed on acrylic before for camera calibration? How did you do it? 

 

I am trying to avoid printing on paper and then gluing it to the bottom of the acrylic if possible. Having the dot grid printed directly on the acrylic is a much more elegant solution that I would like to achieve. 

 

Thanks!
