Andrews’ method of homemade colour separation evokes both the 19th-century painting technique of Pointillism: “in which small, distinct dots of pure color are applied in patterns to form an image”, and the Ben-Day dots of mechanical printing. Beyond these references, Andrews’ uses the technique to, at the same time, evoke the alchemy of vision and break its mechanics down. As a result, Andrews creates works that “hover at legibility.” “The pixilation or dot matrix completely obscures details, making specifics impossible to see. We can't grasp the full picture.“ The series of rubbed-crayon
Color printing cannot vary the amount of ink applied to particular picture areas except through "screening," a process that represents lighter shades as tiny dots, rather than solid areas, of ink. This is analogous to mixing white paint into a color to lighten it, except the white is the paper itself. In process color printing, the screened image, or halftone for each ink color is printed in succession. The screen grids are set at different angles, and the dots therefore create tiny rosettes, which, through a kind of optical illusion, appear to form a continuous-tone image. You can view the halftoning, which
