Summary

The effect of screen mesh size and pigment concentration on silk screen image quality, density, and resolution was evaluated. A standard test pattern, consisting of half-tone images, characters (over a range of size), and gray-scale was applied directly and indirectly (via decal) on floor tiles. After printing, the tiles were fired then analyzed using surface roughness (via optical interferometry), scanning electron microscopy, and optical microscopy. The optical interferometry technique allowed for the quantification of both surface roughness and deposition volumes. Other experimental variables included: pigment solids loading, screen mesh size, off contact area, squeegee printing angle, dots per inch, and lines per inch (for the computer generated masters). Correlations are made between the fired sample analysis, experimental variables, and qualitative observations concerning silk-screened halftones, on-glaze ink deposit, moire patterns, and the overall image quality.
