Abstract
Claims
1. A first ejection step involves ejecting a first ink, which is a radiation-curable inkjet composition, and adhering it to a recording medium. A first irradiation step involves irradiating the first ink adhering to the recording medium with radiation to obtain a cured coating film of the first ink, A second ejection step involves ejecting a second ink, which is a radiation-curable inkjet composition, and depositing it onto the cured coating film of the first ink in multiple dot sizes such that the duty cycle is 5% or more and 30% or less. A second irradiation step involves irradiating the second ink adhering to the recording medium with radiation to harden the second ink and obtain a recorded material. The process includes stacking the recording materials such that the recording surfaces to which the first ink and the second ink are attached face each other, and the non-recording surfaces to which the first ink and the second ink are not attached face each other. The aforementioned Duty is expressed by the following formula: Method for manufacturing records. (Duty (%) = Actual number of printed dots / (Vertical resolution × Horizontal resolution) × 100)
2. The first ink is a color ink. A method for manufacturing a record according to claim 1.
3. The second ink is clear ink. A method for manufacturing a record according to claim 1.
4. In the lamination process, the recording material is wound into a roll, thereby the recording surface and, The stacks are arranged so that the non-recording surfaces face each other. A method for manufacturing a record according to claim 1.
5. Both the recording surface and the non-recording surface of the recording medium are non-absorbent. A method for manufacturing a record according to claim 1.
6. The first ink comprises a polymerizable compound containing a monofunctional monomer, The content of the monofunctional monomer is 80% by mass or more relative to the total amount of the polymerizable compound. A method for manufacturing a record according to claim 1.
7. The second ink comprises a polymerizable compound containing a polyfunctional monomer, The polyfunctional monomer comprises a vinyl group-containing (meth)acrylate represented by the following formula (1): H 2 C=CR 1 -CO-OR 2 -O-CH=CH-R 3 ・・・ (1) (In the formula, R 1 R is a hydrogen atom or a methyl group, 2 R is a divalent organic residue having 2 to 20 carbon atoms. 3 (This is a hydrogen atom or a monovalent organic residue having 1 to 11 carbon atoms.) A method for manufacturing a record according to claim 1.
