Grid calibration pre-requisites • Start with larger grid size (ex. 70 microns for mono2) • Use the Keystone buttons of the projector to make the horizontal top and bottom lines are in equal length this setting may be changed by macro lens.

Closing the grid calibration • Actual pixel size might be different from the one used during the grid calibration. After the test print, please measure the reference dimension and recalibrate the pixel size in MonoWare. • Projector’s focus dial should be at its end position. If not, the calibrated grid is not reproducible later.
FAQ and troubleshooting Q: Printed dimension is not same as design. How can I correct this dimensional error? A: If the printed dimension is 4.9 mm and the design is 5.0mm, you need to increase the current pixel size by a factor of 5.0/4.9 on MonoWare. So if the old pixel size was 45 microns, the new pixel size will be 45 x 5.0/4.9 = 45.92 microns.
