Digital proofing reproduce color through FM dot proof, which can't measure the printing effect or reflect practical problem during printing by observing dot shape. Screen proofing experiments were carried out with data control printing to imitate AM dot. △E was regarded as the major quality control parameter to measure the improvement of printing quality of proof. The proof was analyzed and evaluated from the aspects of dot shape reproduction, dot transfer characteristics, and color reproduction. The result showed that the dot proof can reproduce printing effect from color aspect and has the salient superiority in imitating dot shape which digital proof can't replace, which can offer the true and predictable printing effective.
