Title:
INKJET RECORDING METHOD USING COLORED INK
Document Type and Number:
WIPO Patent Application WO/2017/014014
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an inkjet recording method for forming a high-quality color image on a thick recording medium having a low thermal conductance rate. The present invention pertains to a single-pass recording type inkjet recording method using an ink set that includes at least two active ray-curing colored inks, the recording method characterized in that between the condition (a) that the gelatinization temperature of the farthest-downstream colored ink be 3.0-15.0°C higher than the gelatinization temperature of the farthest-upstream colored ink, and the condition (b) that the gelatinization temperature of the second and subsequent colored inks from the upstream side in the conveying direction be either the same as the gelatinization temperature of the adjacent upstream colored inks or higher than the gelatinization temperature of the adjacent upstream colored inks, only condition (a) is fulfilled when there are two colored inks included in the ink set, the conditions (a) and (b) are both fulfilled when there are three or more colored inks, and a recording medium having a thermal conductance rate less than 0.10 W/(m・K) and a thickness of at least 0.4 mm is used.
