Print preparation method
Provided is a print preparation method possessing an ejection step in which liquid drops of actinic energy radiation curable type ink-jet ink each containing a polymerizable compound, a photo-polymerizable initiator and a gelling agent are injected from an ink-jet recording head to supply the actinic energy radiation curable type ink-jet ink onto a recording medium, and an actinic energy radiation exposure step, wherein the print preparation method further comprises step (A) in which the recording medium is exposed to electromagnetic waves having a longer wavelength than a wavelength of an absorption wavelength of the photo-polymerization initiator contained in the actinic energy radiation curable type ink-jet ink from a side of a surface on which the image is formed, before conducting the actinic energy radiation exposure step, the print preparation method by which a print having images exhibiting excellent image wear resistance, gloss evenness and image density evenness is provided.
1. A print preparation method comprising:
an ejection step in which liquid drops of actinic energy radiation curable type ink-jet ink each containing a polymerizable compound, a photo-polymerizable initiator and a gelling agent are injected from an ink-jet recording head to eject the actinic energy radiation curable type ink-jet ink onto a recording medium, and
an actinic energy radiation exposure step in which the actinic energy radiation curable type ink-jet ink having been ejected onto the recording medium is exposed actinic energy radiation to form an image,
wherein the print preparation method further comprises step (A) in which the recording medium is exposed to electromagnetic waves having a longer wavelength than a wavelength of an absorption wavelength of the photo-polymerization initiator contained in the actinic energy radiation curable type ink-jet ink from a side of a surface on which the image is formed, before conducting the actinic energy radiation exposure step.
