A dazzling array of printing forms and techniques were in common practice in the Japanese world: besides the relief printing that was common in Taiwan at that time, there were also intaglio prints using copper, zinc, or gold plates, lithographs, and screen printing (serigraphy). Feeling the endless possibilities in printmaking enhanced by modern technology, Liao began studying intaglio printing and lithography.
除了當時台灣可見的凸版木刻畫之外，還有以銅、鋅、合金等金屬為材質的凹版銅版畫、平版的石版畫，和孔版的絹印畫，形式活潑且技法多樣，讓他感受到在科技加持下，現代版畫的無限可能性，自此開始學習銅版與石版技法入門。
