Abstract
The relative ink film thickness of screen tints compared to nearby solid printing areas of two grainless lithographic plates were measured for dot areas from 45% to 95%, using a photometric technique of measuring the relative quantity of ink on a known area of the plate. Four different screen rulings were used - 65 I/in., 150 1/in., 300 1/in. and 500 1/in. It was found that there is no correlation between dot area and ink film thickness for the dot areas from 60% to 95% for the three coarser screens and from 75% to 95% for the 500 1/in. screen. The results do not exclude the possibility of a correlation for dot areas less than 75% for the 500 1/in. screen.
