目的 研究硅藻土壁纸丝网印刷的最佳工艺条件。方法 以印刷压力、 刮板角度和网距等3个主要影响因素为实验因素， 设计正交试验。以实地密度和色差为考察指标， 通过极差与方差分析3个因素对实验结果的影响。结果 硅藻土壁纸丝网印刷的最佳工艺条件为印刷压力0.5 MPa、 刮板角度75°、 网距7 mm。结论 用最佳工艺条件印刷的硅藻土壁纸效果良好， 阶调复制曲线接近理想曲线， 为实际印刷提供了现实依据。

Objective To study the optimal condition of screen printing of diatomite wallpaper, to in order to obtain better printing quality. Methods The optimal printing condition was revealed by orthogonal experiment. The printing pressure, squeegee angle and screen distance were introduced as experimental factors. The effects of these factors on the field density and color difference were discussed by range and variance analysis. Results The results showed that the optimal condition was printing pressure 0.5 MPa, squeegee angle 75°, screen distance 7 mm. Conclusion The printing effect of diatomite wallpaper printed under optimal condition was good, and its tone reproduction curve was close to the ideal curve. This study provides practical basis for actual printing.
