pcb photoengraving

Hi friends
Did anyone knows how to use photoengraving glue for exposing copper clad.

I think that has to mix with water and Ammonium bichromate.
if anyone knows how to prepare the photosensitive solution please share.

I hope the procedure for making blocks for printing press is same.

regards
Benoy
