In the printing workshop, there is a seemingly insignificant but crucial tool - the printing sponge. It is responsible for the uniform transfer of ink, the cleaning and maintenance of the printing plate, and even directly affects the color accuracy of the printed product. For a long time, traditional wood pulp sponges have troubled printing masters due to problems such as easy breakage and insufficient water absorption. Recently, an innovative product called Ceres sponge is quietly changing this situation. Its unique wood pulp + cotton pulp composite formula not only increases the water absorption of the sponge by 30%, but also extends its service life by more than 2 times, becoming the "best partner" praised by printing masters.
