Embodiment 1

[0008] The invention is composed of 68.5% of scarlet ink, 15.1% of peach red ink and 16.4% of white ink in weight percentage, and the scarlet ink, pink ink and white ink are mixed together and stirred evenly to obtain the product.

Embodiment 2

[0010] The invention is composed of 70.9% of scarlet ink, 16% of peach red ink and 13.1% of lightening agent in weight percentage, and the scarlet ink, pink ink and lightening agent are mixed together and stirred evenly to obtain the product.

Embodiment 3

[0012] The invention is composed of 72.1% of scarlet ink, 15.4% of peach red ink and 12.5% ​​of varnish in weight percentage, and the scarlet ink, peach red ink and varnish are mixed together and stirred evenly to obtain the final product.

[0013] The present invention uses common inks and fillers on the market to prepare map printing spot color ink map red, and tests are carried out under actual printing conditions. After verification, the color difference between the prepared spot color ink map red and the original spot color ink map red is small At the same time, the printing suitability of the ink has been greatly improved, the coloring power of the ink is improved, the transfer performance is better, the ink-water balance is easy to control, the drying time is shorter than that of the original spot color ink map red, the effective shelf life is longer, and the printing suitability is improved. The experimental data and effect analysis are as follows:

Abstract

The invention relates to a preparation method of spot-color ink map red for map printing, effectively solving the problem that the ink has higher viscosity, low fluidity and longer drying time and is not suitable for high-speed printers. The preparation method is characterized by mixing 68.5-72.1% of bright red ink, 15.1-16% of pink ink and 11.9-16.4% of additive by weight and stirring the mixture uniformly, thus obtaining the spot-color ink map red, wherein the total weight percent is 100%. The spot-color ink map red blended by the preparation method has the following beneficial effects that the printability of the ink is greatly improved through practical printing test; the tinting strength and fluidity of the ink are good; the tinting strength is improved; ink balance is easy to control in the printing process; the ink drying time is shortened; and the printability is greatly improved..

Description

technical field [0001] The invention relates to a preparation method of map red spot color ink for map printing. Background technique [0002] At present, map printing uses map red ink, which is called spot color ink because of its special color. However, this kind of ink uses finished spot color resin ink, which has high viscosity, low fluidity, and long drying time. It is suitable for use on low-speed offset printing machines with a printing speed of about 5,000 sheets / hour. Pulling will occur when using high-speed printing machines. Problems such as paper lint, insufficient ink transfer, poor colorability, and difficult to control the balance of ink and water restrict the performance of high-speed printing machines and the improvement of printing quality, and so far there has been no report on the deployment of spot color ink Map Red. Contents of the invention [0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the...
