1. Thanks to the photomechanical effect, part of the laser energy ruptures the membrane of the adipocytes closest to the end of the fibre.

2. Photomechanical transfer (PMT): Paper negative exposed in the normal way and developed in contact with positive material.

3. Original plate: Relief printing plate produced bu 7 photomechanical etching as distinct from electrotyping.

4. Natural protein, soluble in water and most commonly found in the Albumins, the colloid used for certain dichromated sensitizes employed in photomechanical process.

5. A new method to realize the curve fitting by MATLAB and obtain the photomechanical parameters in the photopolymer , based on the theoretical model and experimental data, was analyzed.

6. The maximum density that can be achieved in a given photographic or photomechanical system.

7. Albumin( Albumen): Natural protein, soluble in water and most commonly found in the Albumins, the colloid used for certain dichromated sensitizes employed in photomechanical process.

8. The lowest density that can be achieved in a given photographic or photomechanical system.
