Study of Emulsion Shift on Ballistic Camera Plates

摘要

Process treatments and emulsion batches were studied for their effect on the quantity of emulsion shift. Assignable linear vector shift of .4 micron per cm was identified; the assignable random emulsion shift appears to be in the order of .7 micron. The study indicated that the final rinse has the most significant process effect on both systematic and random shifts. The fixer, use or nonuse of a prehardener, different process runs and vertical vs. horizontal drying had no identifiable significant effects. The emulsion batches demonstrated significant effects. The reading error continues to be the most significant factor in error of position determination. It was concluded that an emulsion change between batch 1H1 and the other three batches has been beneficial; and further, that while the process treatments can be aligned for optimum treatment, no significant improvement in data quality can result from further process adjustment.
