[0002] Compared with traditional gravure printing machines, digital printers have the advantages of flexibility and speed. They can realize small batches and multiple varieties, and can print on different media, including metal plates, crystal materials, wood plates, glass plates, leather, cloth and stone. However, the shortcomings of digital printers are also obvious. The most disadva...

Abstract

The invention discloses a method for enabling high light fastness of ink of a digital printer to reach the standard. The method comprises the following steps: step 1, weighing 50-60 parts by weight of matrix dye, 15-20 parts by weight of an anti-ultraviolet agent, 5-8 parts by weight of a light stabilizer and 10-20 parts by weight of a leveling agent; step 2, opening a file to be printed in Photoshop software, copying a cyan channel in the file, adding a curve below 40% of the original cyan channel to reduce the cyan channel to be shallow, and adding the curve to the copied channel to deepen the level of the channel; and step 3, opening Ajet software, carrying out channel setting in the Ajet software, importing the file, and printing the file. According to the invention, the high-light-fastness ink is prepared from the matrix dye, the anti-ultraviolet agent, the light stabilizer and the leveling agent, the printed file is processed through the Photoshop software, and meanwhile, the high-light-fastness standard of the digital printer is realized through multi-channel printing arranged in Ajet software, so that the light fastness of printing of the digital printer reaches the fourth level or above, and then the light fastness of the digital printer is improved.

Example Embodiment

[0019] The technical solutions in the embodiments of the present invention will be apparent from the embodiments of the present invention, as will be described, as will be described herein, not all of the embodiments of the invention, not all of the embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the present invention without making creative labor premise.

[0020] The present invention provides a method of reaching a fastness based on digital printer, including the following steps:

[0021] Step 1: Preparation of ink, weighing the weight of the weight: 50-60 parent dyes, 15-20 parts of UV-UV, 5-8 parts of the light stabilizer and 10-20 parts, will be weighing the raw material A series of processed inks such as grinding, stirring, etc., made ink into the digital printer, by the mother dye, anti-UV agent, light stabilizer, and the same, high-sunshine, during preparation, need The raw material mixing was stirred and pressed and ground fine dispersed, with a large mechanical pressure and shear force overcome the cohesive force between the respective raw materials, and finally formulated a suspension colloidal ink, put the resulting ink into the ink cartridge, and will The ink cartridge with ink is mounted to the digital printer, that is, the ink can be used via the digital printer;

[0022] Step 2: Drawing software processing, open the file to be printed in Photoshop software, copy the blue channel in the file, and drop the original blue channel 40% below the curve to drop it, the copied channel plus curve The layers are deepened, by copying the cyan channel, closing the channels before and replication, and deepened, thereby setting the file to be printed, so that the digital printer is printed by this print file. The sunshine is more fast, meets the high sun fastness requirements;

[0023] Step 3: Digital printer software settings, open the AJET software, and perform channel settings in the AJET software, after the setting is completed, print the file, print the file, make the digital printer printed by the digital printer High, can meet the high sun fastness requirements of the product;

[0024] In step one, the parent dye is hydrazine, the phthalocyanine is a parent structure of the dye, anthraquinone, phthalocyanine is good, so that the resulting ink has a high sunlight fastness. ;
