sandwich printing 指的是什么印刷工艺？

据维基，Sandwich printing, also known as negative sandwiching, is a photographic technique created by combing two negatives or slides into the film carrier of the enlarger and printing on one sheet of paper as one image. This technique is generally used to create a juxtaposition of image elements that would not occur naturally in the world. Sandwich printing works in both black and white and color images.

应该是底片叠加印刷。

是指印刷透明材料时，为达到纸张双面印刷的效果，但是油墨又只在一面的印刷方式
通常在9色以上，即ymck white kcmy
两层四色夹住白墨，形似三明治

:happy:谢谢两位大侠的解答。

这种思路不错,不过一个白墨印可能印不实

对的 估计2关以上白 才出得来效果。

这种印刷方式市场上特定的火腿肠的包装使用(如SH的韩国烧烤肠包装)，白班雕刻要求深，白后的颜色一般是黑字，最多两色，印四色容易透和花
