1. A pattern forming the perspective latent image and the base pattern are unified designed and printed simultaneously in one time to adhere with the carrier via the engraving gravure printing mode.

2. At this stage there is a latent image which is not yet visible.

3. The fogged internal latent image grains are protected by mercapto development antifoggants.

4. Image, Latent Image: The invisible image formed in a camera or printer by the action of light on a photographic emulsion.

5. In the process of developing a photo, a latent image can only come out when the photosensitive material is developed.

6. The resulting latent image is optically coupled to the semiconductor detector and and scanned locally in this detector and digitized pixel by pixel.

7. The latent image declined when it was irradiated by microwave after exposure.

8. The study on the latent image theory is an important problem in the field of photographic science.

9. Provided is an identifying medium which can utilize a multi-tone latent image at a low cost.

10. Simple etch method of partial dissolution and surface development was used to reveal the distribution of internal latent image.

11. The universal method of supersensitization - reduction latensification of the latent image with reductiones is considered.

12. This study showed that the greater the pressure and the longer the pressure time, the more the latent image decay and the less is the image density generated by developing X ray films.

13. The quality of the sensor is determined primarily by the matching of the luminescent layer and the optical coupling of the latent image to the detector element.

14. The formate ion as a kind of hole-to-electron converter doped in silver halide emulsion can enhance photoelectron yield in latent image formation.
