Patent ID: 7270408

Claim:
A method of forming an image from a low viscosity ink on a recording medium comprising: ejecting the low viscosity ink from a printer head in the form of droplets onto an intermediate transfer medium to form the image; partially curing the image on the intermediate transfer medium; transferring the partially cured image onto the recording medium; and further curing the partially cured image on the recording medium to create a hardened image, wherein the low viscosity ink comprises a monomer, a photoinitiator and a colorant, and wherein the partially cured image is formed on the intermediate transfer medium by a radiative energy treatment of UV A (315-400 nm) about 0.2 to 0.8 w/cm 2 , UV B (280-315 nm) about 0.3 to about 1.0 w/cm 2 and UV C (200-280 nm) about 0.05 to about 0.5 w/cm 2 .
