Embodiment 1

[0008] The present invention is by weight percentage: 31.3% of spot color yellow ink, 34.4% of spot color green ink, 0.4% of spot color orange ink and 33.9% of white ink, the spot color yellow ink, spot color green ink, spot color orange ink Mix it with white ink and stir evenly to get it.

Embodiment 2

[0010] The present invention is by weight percent: 33.1% of spot color yellow ink, 36.5% of spot color green ink, 0.5% of spot color orange ink and 29.9% of lightening agent, the spot color yellow ink, spot color green ink, spot color Mix the orange ink and the lightening agent together and stir evenly.

Embodiment 3

[0012] The present invention is made up of spot color yellow ink 34%, spot color green ink 37.6%, spot color orange ink 0.6% and varnish 27.8% by weight percentage, and spot color yellow ink, spot color green ink, spot color Mix orange ink and varnish together and stir evenly.

[0013] The present invention uses common inks and fillers on the market to prepare map printing spot color ink map green, and tests are carried out under actual printing conditions. After verification, the color difference between the prepared spot color ink map green and the original spot color ink map green 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 balance of the ink and water is easy to control, the drying time is shorter than that of the original spot color ink map green, the effective shelf life is longer, and the printing suitability is improved. The experimental data...

Abstract

The invention relates to a preparation method of special green map ink for printing maps, which aims to effectively solve the problems that the conventional ink is relatively high in viscosity, low in flowability and relatively long in drying time, thus being not suitable for high-speed printers. According to the technical scheme, the special green map ink consists of the following components in percentage by weight: 31.3 to 34 percent of special yellow ink, 34.4 to 37.6 percent of special green ink, 0.4 to 0.6 percent of special orange ink and 27.8 to 33.9 percent of additives and is prepared by uniformly mixing and stirring the special yellow ink, the special green ink, the special orange ink and the additives. According to the special green map ink for printing the maps, actual printing tests prove that the printability of the ink is greatly improved, the coloring performance and the flowability of the ink are high, the coloring performance of the ink is improved, the ink balance is easy to control during printing, the ink drying time is shortened, and the printability of the ink is greatly improved.

Description

technical field [0001] The invention relates to a preparation method of map printing spot color ink map green. Background technique [0002] At present, map printing uses map green 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 green. Contents of the invention [0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of t...
