As a result, it was found that the lateral compressive force due to drying shrinkage was larger than the lateral compressive force due to the Poisson stress, and that the lateral compressive force significantly changed due to variations in the fiber orientation of coated paper and the type of size breath. It was found that the lateral compression force in ring printing was dependent on the drying shrinkage force.
