Technical Field

The invention relates to the technical field of printing, in particular to a coloring method for printing.

Background

Printing is a technology of transferring printing ink to the surface of paper, fabric, leather and other materials through the processes of plate making, ink applying, pressurizing and the like of originals such as characters, pictures, photos and the like, and copying the contents of the originals in batches.

The prior art has the following defects and shortcomings:

the existing wood printing method has unstable color after coloring, and is easy to fade after long-time use.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a coloring method for printing, which can solve the problems that the color is unstable and is easy to fade after being used for a long time after the existing wood printing method is used for coloring; the invention effectively solves the problems of unstable color and easy fading after long-time use after the existing wood printing method is used for coloring by adopting the coloring method for printing.

In order to achieve the purpose of the coloring method for printing, the invention provides the following technical scheme: a coloring method for printing comprises the following steps,

firstly, removing dust and oil stains on wood to be printed;

selecting sand paper according to the effect of the required printing color;

step three, for smooth wood, firstly polishing away scars by using small-size abrasive paper, and then continuously polishing by using large-size abrasive paper;

step four, wiping the wood chips with a wet cloth after polishing;

step five, wearing gloves, and uniformly stirring the colorant;

step six, brushing the coloring agent with a sponge, a brush or a clean cloth along the wood grain gently to cover all the wood uniformly;

step seven, after a period of time, the wood fully absorbs the colorant;

and step eight, drying the wood after printing and coloring in a heating chamber, and covering the surface of the wood with a transparent material after coloring and drying.

Preferably, the deeper the effect of the color to be printed, the smaller the sandpaper number selected, the rougher the sanded wood is, and the more the colorant is absorbed, and conversely, the lighter the effect of the color to be printed, the larger the sandpaper number selected, the finer the sanded wood is, and the less the colorant is absorbed.

Preferably, the small-size sand paper is 60 or 80, and the large-size sand paper is 100 or 120.

Preferably, the interval time is 5 to 15 minutes.

Preferably, the drying temperature is 110 °.

Preferably, the transparent material is polyurethane gloss paint, if liquid gloss paint is selected, a brush is used for brushing, bubbles or dripping is avoided, after brushing is finished, the second layer is brushed at an interval of 4 hours, if gaseous gloss paint is selected, spraying is carried out, the gloss paint is sprayed 20-30 cm away from the surface of the wood material, two layers are thinly sprayed, and the second layer is sprayed at an interval of 2-3 hours.

Preferably, the waiting time for coloring the wood at the medium and low humidity is not more than 15 minutes, and the coloring time is controlled to be 5 to 8 minutes under the high humidity environment.

Compared with the prior art, the invention provides a coloring method for printing, which has the following beneficial effects:

this coloring method for printing is polished through setting up different abrasive paper, guarantees timber surfacing, improves the degree of consistency of coloring and the effect of coloring, goes up the colorant in addition through polishing the back, carries out drying process to the colorant again, can guarantee painted stability like this, on the basis that possesses stability, the colorant can be more stable, encapsulates through transparent material polyurethane gloss paint at last, polyurethane gloss paint plays protection and beautifies the effect, makes the colour lacquer preserve for a long time.

Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A coloring method for printing comprises the following steps,

firstly, removing dust and oil stains on wood to be printed;

selecting sand paper according to the effect of the required printing color;

step three, for smooth wood, firstly polishing away scars by using small-size abrasive paper, and then continuously polishing by using large-size abrasive paper;

step four, wiping the wood chips with a wet cloth after polishing;

step five, wearing gloves, and uniformly stirring the colorant;

step six, brushing the coloring agent with a sponge, a brush or a clean cloth along the wood grain gently to cover all the wood uniformly;

step seven, after a period of time, the wood fully absorbs the colorant;

and step eight, drying the wood after printing and coloring in a heating chamber, and covering the surface of the wood with a transparent material after coloring and drying.

In conclusion, in the second step, the deeper the effect of the color to be printed is, the smaller the sand paper number is selected, the rougher the ground wood is, and the more the colorant is absorbed, and conversely, the lighter the effect of the color to be printed is, the larger the sand paper number is selected, the finer the ground wood is, and the less the colorant is absorbed, so that the printing effects of different colors can be obtained by selecting different types of sand paper for grinding; the small-size sand paper in the third step is selected to be 60 or 80, the large-size sand paper is selected to be 100 or 120, scars can be polished off by the small-size sand paper, and fine grinding is performed by the large-size sand paper, so that the surface flatness of the wood is improved, and the coloring effect is improved; the interval time in the seventh step is 5-15 minutes, when the wood can fully absorb the colorant, and when the colorant is too short, the colorant is not fully absorbed, and when the colorant is too long, the drying effect is influenced; in the eighth step, the drying temperature is 110 degrees, which is the most suitable drying temperature; the transparent material in the step eight is polyurethane gloss paint, if liquid gloss paint is selected, a brush is used for painting, bubbles or dripping are avoided, after painting is finished, the interval is 4 hours, then a second layer is brushed, if gaseous gloss paint is selected, spraying is used, 20-30 cm of gloss paint away from the surface of the wood is sprayed, two layers are sprayed in a thin mode, the interval is 2-3 hours, the second layer is sprayed, the polyurethane gloss paint plays a role in protection and beautification, and the color paint is stored for a longer time; the waiting time for wood coloring does not exceed 15 minutes under medium and low humidity, otherwise the color looks old, and the coloring time is controlled to be 5 to 8 minutes under high humidity environment for the best coloring effect.

The working use process and the installation method of the invention are that when the coloring method for printing is used, different abrasive paper is arranged for polishing, the surface smoothness of the wood is ensured, the coloring uniformity and the coloring effect are improved, in addition, the coloring agent is coated after polishing, and then the drying treatment is carried out on the coloring agent, so the coloring stability can be ensured, on the basis of having the stability, the coloring agent can be more stable, and finally, the polyurethane gloss paint is packaged through the transparent material polyurethane gloss paint, so the polyurethane gloss paint has the protection and beautification effects, and the color paint can be stored for a longer time.
