CN105435667A - Mixing method for screen printing ink - Google Patents

Abstract

The invention discloses a mixing method for screen printing ink. The mixing method comprises the following steps: analyzing color phases according to an original printing manuscript, determining which types of printing ink can be mixed properly, determining a main color and auxiliary colors, determining a proportion, and reducing the number of types of printing ink of different colors as far as possible; then pre-mixing, spraying mixed printing ink on one side of a piece of paper, scraping the mixed printing ink to ensure that the thickness of the mixed printing ink is as thick as required via another piece of paper, comparing the scrapped printing ink with the original printing manuscript to judge whether the mixed printing ink is proper or not; finally, according to the comparing result, carrying out printing on a sample or continue pre-mixing till the comparing result shows that the mixed printing ink is proper, carrying out printing on the sample, and mixing according to the pre-mixing proportion if the printed sample meets requirements. The mixing method has the advantage that the brightness and the saturation of printing ink mixed according to the mixing method are improved.

Description

A kind of mixed tune method of silk-screen ink

Technical field:

The present invention relates to print field, is specifically the mixed tune method of a kind of silk-screen ink.

Background technology:

In prior art, the mixed ink for screen printing adjusted is for gold and silver paperboard, and color is bright-coloured not, and the degree of accuracy of brightness and spot color is not ideal enough.

Summary of the invention:

Technical problem to be solved by this invention is to provide a kind of mixed tune method of ink for screen printing, and after making the mixed tune of ink, bright-coloured saturation degree increases.

Technical solution of the present invention is, provide a kind of mixed tune method of ink for screen printing, it comprises the following steps:

First, analyze form and aspect according to printed original, which measures, and to plant ink formulation suitable and determine ink mass-tone and auxiliary look, and determine ratio, will reduce the amount of ink of different colours during selection as far as possible;

Then, carry out examination adjust, adopt the scraps of paper wherein one piece of paper coat adjusted ink, scrape the ink film thickness to required printing with another block paper, and with original copy contrast see whether suitable;

Finally, carry out sample printing or continue examination adjusting according to contrast situation, until carry out sample printing after suitable, printing composite demand can carry out mixed tune in examination tune ratio.

As preferably, darker than original copy mass colour when examination adjusts the mass colour of ink to allocate.The tinctorial pattern of such printing is more accurate.

Compared with prior art, the present invention has following technique effect, can allow bright and full color as far as possible, and luminosity is also better.

Detailed description of the invention:

Below in conjunction with detailed description of the invention, the invention will be further described:

Embodiment

A mixed tune method for ink for screen printing, it comprises the following steps:

First, form and aspect are analyzed according to printed original, which measures, and to plant ink formulation suitable and determine ink mass-tone and auxiliary look, and determine ratio, the amount of ink of different colours to be reduced during selection as far as possible, during inking, use the ink of different colours as far as possible less, that is, with two kinds of black furnishings, just can not remove tune with three kinds of ink, in order to avoid the glossiness of reduction ink and bright-coloured saturation degree;

Then, carry out examination adjust, adopt the scraps of paper wherein one piece of paper coat adjusted ink, scrape the ink film thickness to required printing with another block paper, and with original copy contrast see whether suitable; Darker than original copy mass colour when examination adjusts the mass colour of ink to allocate, the tinctorial pattern of printing is more accurate like this.

Finally, carry out sample printing or continue examination adjusting according to contrast situation, until carry out sample printing after suitable, printing composite demand can carry out mixed tune in examination tune ratio.
