Abstract: Provided is a printing system with intelligent color-matching, including a storage device, a printing device, and a processing device. The storage device stores a program, a color-matching dataset, and a color-matching model. The color-matching dataset contains multiple pieces of color-matching data, and each piece of color-matching data includes an ink formula and a corresponding printing color value for the ink formula. The printing device is controlled to produce printed products. The processing device loads the program from the storage device to perform the following tasks: training the color-matching model using the color-matching dataset; inputting the expected color value into the trained color-matching model, and obtaining a predicted formula output by the trained color-matching model; and based on the predicted formula, controlling the printing device to produce the printed product.

Abstract: An ink is provided, which includes a resin, UV curable monomer, and photo initiator. The resin is formed by reacting a plurality of end capping agents with a dendrimer compound in an environment including esterification catalyst, inhibitor, and first solvent. The dendrimer compound is formed by reacting a multi-hydroxy compound and a plurality of hydroxy-containing epoxy compounds in an environment including alkaline catalyst and second solvent. The multi-hydroxy compound and the hydroxy-containing epoxy compounds have a molar ratio of 1:6 to 1:20, and the multi-hydroxy compound and the end capping agents have a molar ratio of 1:6 to 1:20. The end capping agents include acrylic acid, methacrylic acid, glycidyl methacrylate, or 2-amino acrylic acid. The resin and the UV curable monomer have a weight ratio of 100:30 to 100:5000, and the resin and the photo initiator have a weight ratio of 100:30 to 100:500.
