Problems solved by technology

At present, 4-color and 6-color printers often have problems of color cast and poor layering when printing black and white images. In order to solve this problem, the present invention has developed 6-color dye inks made of different black dyes. , 6 colors have different black dye concentration and different dye hue control, so that when printing the gray area of ​​black and white images, the layering is more detailed and basically no color cast

Abstract

The invention relates to a water-based dye ink for jet printing of black and white images, which is characterized by comprising the following components in percentage by weight: 0.72-5 wt% of black dye, 5-40 wt% of humectant, 1-10 wt% of viscosity modifier, 0.05-1 wt% of bactericide, 0-1 wt% of chelator, 0-1 wt% of pH buffer, 0-5% of surfactant and the balance of deionized water. When the water-based dye ink for jet printing of black and white images is applied to a desktop piezoelectric printer, different concentration gradients of several colors are regulated by the black dye; when being used for printing black and white images, the water-based dye ink for jet printing of black and white images has excellent color reproducibility which is obviously superior to that of the black and white images printed in a colored ink black and white mode; and besides, the water-based dye ink for jet printing of black and white images has excellent printing smoothness, printing stability and storage stability.

Description

technical field [0001] The invention relates to a water-based dye ink, in particular to a water-based dye ink for inkjet printing of black and white images. Background technique [0002] At present, many professional photographers use inkjet printing to print black and white images in pursuit of antique effects or other special visual effects. In addition, there are also medical imaging customers who print medical images on PE (polyethylene) media, with black and white image effects, which have higher requirements for black and white images. Now the ink on the market has 4 colors, 6 colors, 8 colors, and 11 colors. For example, Epson C86 has 4 colors, Epson Stylus Photo R270 has 6 colors, Epson Stylus Photo 7880 has 8 colors, and Epson Stylus Photo 9910 has 11 colors. For example, the ink on the 4-color and 6-color machines has only one black color, so the black and white image is printed by black, and the grayscale part is superimposed by color. If the grayscale is superi...
