Description
(1)濡れ性−コーティングされたTORAY ITMの上にKYOCERAヘッドで吐出した水系インクのラインおよびドット。液滴の広がりおよびラインの幅を顕微鏡で観察した。ポリウレタンコーティング、特に、添加剤を含まないポリウレタン(図5B)および0.5% SILCLEANポリウレタン(図5C)は、図5AのコーティングされていないTORAY ITMコントロールと比較して、良好なインク広がり性およびライン幅を示した。
(2)剥離性−ITMプレートを加熱し、紙に対し、加圧ローラーを用いたハンドプレス加工によって紙への転写を行った。コーティングを伴うインクは、ITMの上に残留せずに、紙に完全に転写し、紙の上で固定される。
