(2)塗佈厚度
固定捲收速度1rpm、UV樹脂黏度270 cps、壓印力0.42MPa，針對塗佈厚度對轉寫率之成形實驗，進行三種厚度(8、12、16 μm )之滾壓成形，轉寫率分別為96.4%、97.2%、96.5%，結果顯示由塗佈厚度12 μm，擁有最佳平均轉寫率97.2%。
(3)不同UV樹脂黏度
固定捲收速度1 rpm、塗佈厚度12 μm、壓印力0.42 MPa，進行270 cps、960 cps之樹脂黏度成形實驗，各區域平均轉寫率分別為97.2%、98.2%。
(4)不同壓印力
固定塗層厚度12 μm、捲收速度1 rpm、UV樹脂黏度270 cps，分別以0.26 MPa、0.39 MPa、0.59 MPa三種壓印力進行實驗，平均轉寫率分別為97.2%、97.2%、97.8%。
對預期深度30 μm的模仁，實驗結果如下:
(1)有無背壓輪
固定捲收速度為1 rpm、塗層厚度25 μm、UV樹脂黏度270 cps，進行有無背壓輪的滾壓，有、無背壓輪分別得到各區域平均轉寫率為96.6%、89.2%。
(2)塗佈厚度
固定捲收速度1 rpm、UV樹脂黏度270 cps、壓印力0.59 MPa，針對塗佈厚度對轉寫率之成形影響進行三種厚度(20、25、30 μm )之滾壓成形成形，轉寫率分別為94.9%、95.6%、94.8%
(3)不同UV樹脂黏度

(4)不同壓印力
固定捲收速度1 rpm、塗佈厚度25 μm、UV樹脂黏度270 cps，分別以0.26 MPa、0.39 MPa、0.59 MPa三種壓印力進行實驗，平均轉寫率分別為95.9%、96.9%、95.8%。

This study investigates Roll-to-Roll (R2R) imprinting LIGA-like process in making of microcup structures for electronic paper application. Using the Roll-to-Roll imprinting machine developed by our laboratory, R2R imprinting experiments with expected microstructure depths of 15 μm and 30 μm were carried out to investigate the effects of various R2R imprinting parameters on the replication rate.
Experiments results with 15 μm microstructure depth:
(1) With or without backing roller
Operating at imprinting speed of 1 rpm, coating thickness 12 μm, and UV resin viscosity 270 cps, the replication rate is 97.2% for both cases.
(2) Coating thickness
Operating at imprinting of 1 rpm, UV resin viscosity 270 cps, and imprinting pressure 0.42 MPa, experiments with 3 different UV resin coating thicknesses (8, 12, and 16 μm) were carried out, the replication rates were 96.4%, 97.2%, and 96.5%, respectively.
(3) Different UV resins viscosity
Operating at imprinting of 1 rpm, coating thickness 12 μm, and imprinting pressure 0.42 MPa, the replication rates were 97.2%, 98.2% for UV resins of viscosity 270 cps and 960 cps, respectively.
(4) Different imprinting pressure
Operating at imprinting of 1 rpm, coating thickness 12 μm, and UV resin viscosity 270 cps, the replication rates were 97.2%, 97.2% and 97.8% for imprinting pressures of 0.26 MPa, 0.39 MPa, and 0.59 MPa, respectively.
Experiments results with 30 μm microstructure depth:
(1) With or without backing roller
Operating at imprinting of 1 rpm, coating thickness 25 μm, UV resin viscosity 270 cps, the replication rates were 96.6%, 89.2% for with and without backing roller, respectively.
(2) Coating thickness
Operating at imprinting of 1 rpm, UV resin viscosity 270 cps, and imprinting pressure 0.59 MPa. Experiments with 3 different UV resin coating thicknesses (20, 25, and 30 μm) were carried out, the replication rates were 94.9%, 95.6%, and 94.8%, respectively.
(3) Different UV resins viscosity
Operating at imprinting of 1 rpm, coating thickness 25 μm, and imprinting pressure 0.39 MPa, the replication rates were 95.7%, 97.0% for UV resins of viscosity 270 cps and 960 cps, respectively.
(4) Different imprinting pressure
Operating at imprinting of 1 rpm, coating thickness 25 μm, and UV resin viscosity 270 cps, the replication rates were 95.9%, 96.9% and 95.8% for imprinting pressures of 0.26 MPa, 0.39 MPa, and 0.59 MPa, respectively.
