Foam formation is a serious problem that can adversely affect the production of radiation-cured printing inks and overprint varnishes. When it occurs during the grind and drum filling steps, it can inhibit efficiency, increasing production time and generating quality problems. This ultimately results in higher costs. If it is incorporated into pigmented inks during the grind stage, it can interfere with the dispersion process and also inhibit color strength development. Even those mixing proced...
