Split Halftone Cell Technology is a specific set of PostScript codes that describes to an printing device, how to break down image information. This technology splits the traditional halftone cell in half twice thus yielding four quadrants. Where once there was one halftone dot there are now four dots occupying the same area. It is hypothesized that this technology should enhance the resolution of a target piece twofold, because the halftone dots ultimately determine detail and gray levels. With the use of special software, this new screening technique was used on a fixed resolution imagesetter device to output several test forms for this study. This project addresses resolution, gray levels, dots and spots, as well as tests the claims of split halftone cell screening technology either to be true or false. It was determined that Split Cell screening excelled in bitmap image detail and smooth gradients when image sampling of 200 ppi and higher was used. If a user is limited to only a 1200 epi device than Split Cell screening would allow for higher/finer line rulings.
