Problems solved by technology

However, the color drafts printed on digital paper and digital machines often cannot truly present the products to be printed in batches. Therefore, customers will not accept such digital paper color drafts because they are inconsistent with the original paper of the printed matter of the actual purchase order. sign or even lose order for it
[0003] Some customers also had conflicts because they accepted the color draft printed out earlier, and there was a color difference between the subsequent printing and the original color draft

preparation example Construction

[0026] A method for preparing ink, which is characterized in that it comprises the following steps:

[0027] Step 1. Weigh the raw materials according to weight percentages: maleic rosin resin, polyacrylic acid resin and silicon dioxide, add the above raw materials to the reaction kettle in sequence, fully stir at a temperature of 50-60°C, and continue stirring for 60-80 minutes;

[0028] Step 2: Weigh the raw materials: water-based pigments and distilled water according to the weight percentage, and put them into the above reaction kettle, and continue to stir for 60-80 minutes at a temperature of 45-55°C;

[0029] Step 3: Weigh the raw materials according to weight percentage: put the wetting agent, plasticizer, diluent and dispersant into the above-mentioned reaction kettle, and continue to stir for 10-20min at a temperature of 40-50℃;

[0030] Step 4: After completion, let it stand, and finally filter out the material to prepare the ink.

Embodiment 1

[0033] S1. Weigh the raw materials according to the weight percentage: 13% maleic rosin resin, 16% polyacrylic resin and 15% silica. Add the above-mentioned raw materials to the reactor in turn, stir fully at 60°C and continue stirring for 70 minutes ;

[0034] S2: Weigh the raw materials according to weight percentage: 20% of water-based pigment and 23% of distilled water, put them into the above reaction kettle, and continue to stir for 60 minutes at a temperature of 55°C;

[0035] S3. Weigh the raw materials according to weight percentage: 1% glycerin, 3% dioctyl phthalate, 6% water-soluble aldehyde and ketone resin and 3% polyethylene glycol, put them into the above-mentioned reaction kettle at a temperature of 50°C Stir continuously for 20 minutes;

[0036] S4. After completion, let it stand, and finally filter out the material to prepare the ink.

Embodiment 2

[0038] S1, weigh the raw materials according to weight percentage: maleic acid rosin resin 16%, polyacrylic resin 18% and silicon dioxide 14%. Add the above raw materials to the reactor in turn, stir fully at 55°C and continue stirring for 70 minutes ;

[0039] S2: Weigh the raw materials according to weight percentages: 21% of water-based pigments and 20% of distilled water, put them into the above reaction kettle, and continue to stir for 60 minutes at a temperature of 50°C;

[0040] S3. Weigh the raw materials according to the weight percentage: 1% glycerin, 3% dioctyl phthalate, 4% water-soluble aldehyde and ketone resin and 3% polyethylene glycol into the above-mentioned reaction kettle at a temperature of 50°C Stir continuously for 20 minutes;

[0041] S4. After completion, let it stand, and finally filter out the material to prepare the ink.

Abstract

The invention discloses ink comprising the following components in percentage by weight: 10-20% of maleic acid rosin resin, 15-20% of polyacrylic resin, 10-20% of silica, 20-30% of water-based pigment, 15-25% of distilled water, 1-3% of a wetting agent, 3-5% of a plasticizer, 3-6% of diluent, and 1-5% of a dispersant. The ink is suitable for printing of digital machines, can be used on printing base paper, and has a good color proof effect. The invention also discloses an ink preparation method, which can reduce the cost and is easy to implement.

Description

Technical field [0001] The invention relates to an ink and a preparation method thereof. Background technique [0002] In traditional offset printing, it is necessary to print out digital color drafts by using digital paper and digital machines before mass production, and give customers color confirmation. However, often the color drafts printed on digital paper and digital machines do not truly represent the products to be printed in batches. For this reason, customers will not accept such digital paper color drafts because they are inconsistent with the original paper of the actual purchase order. The signature even lost the order for this. [0003] There are also customers who have accepted the color manuscript printed earlier, and there is a color difference between the original color manuscript after subsequent printing and conflicts. Summary of the invention [0004] The purpose of the present invention is to provide an ink which is suitable for digital printing, can use pri...
