Comparison of high definition television and film;

The article introduces the difference of highdefinition and high fidelity color printing technology.

The effect of PMAs'addition in the ink jet coating layer on the speed of ink absorption, definition and the image density was examined.

Paste Flowability Effect on the Outline Sharpness in Printing;

The feasibility of the determination of the image sharpness and MTF by a scanner was discussed,and some sharpnesses of T-grain,cubic and potato-shaped AgBrI photographic emulsions were determined by the scanner and the PDS microdensitometer,respectively,and MTFs of the commercial black white film developed by different developers were obtained with the same procedures.
