Select one for the best stencil thickness, color/hardness, and definition. Features include a 65-line screen ruling and halftone dots in 10, 50, and 90% areas. Also, the edge definition/resolution targets have a break and very fine type to assist your interpretation. A complete instruction guide is provided with each calculator. |
