Mask calibration print

I'm thinking a way to make a mask calibration print with pillar where you can choose the amount of pillar like in the mask generator
Mask.jpg

And the mask intensity goes down along the z axis

than after the print is done, the user measure the xy size of each pillars an choose the mask intensity for the correspond area.

What do you think about it?  A practical way to generate a mask without sensors.

Re: Mask calibration print

I did not get the point. How they will know how much they should input for the individual point?

Re: Mask calibration print

Hi,
Each pillar will have 20 differents intensities and 20 points to measure.
After the print done you have to measure each point and choose the closest dimension.

after it you put the right rgb value for each pillar

Re: Mask calibration print

Do you count on changing size of pillars to measure light intensity? Do you think it is linear correlation between two?

Re: Mask calibration print

Yes
When it have more light the bigger it gets.
Yes, this is the principle of the mask, to get even expose to have better accuracy.
more light intensity more it will be bigger too.

Re: Mask calibration print

But you know if the picture is out of focus for projector you can get big solid piece (larger than expected) or nothing at all.
Some of the mask usage countering focus problem for projectors. Your suggestion could be useful for LCD users.

They can use after adjusting focus/distortion
