Nowadays, the pigments of digital oil painting wholesale on the market are important, so environmentally friendly acrylic is the main product. All patterns of digital oil painting are composed of basic shapes and colors, and colors constitute an important part of our images.

Color allocation and toning method

(1) "From shallow to deep", especially when using pigments with strong tinting power, avoid excessive amounts.

(2) When mixing gray, green and other multi-color paints, due to the preparation of multiple pigments, the difference in density and oil absorption of the pigments, it is likely that signs of "floating color" and "blooming" will occur. At this time, you can add trace amounts as appropriate. Appearance active agent or leveling agent, anti-floating agent to handle. As usual, 0.1% silicone oil is used for prevention and treatment. The various appearance active agents produced by  Company need to be distinguished by easy paint by numbers which solvent system is used, and the amount of participation is usually 0.1% to 1%.

(3) When the paint by numbers personalized color is matched, there will be a small difference between the color of the paint and the dried film. The color of various paints is usually lighter when it is a wet film, and when the paint dries, the color becomes darker. Therefore, if the incoming sample is a dry sample, the color-matching paint needs to wait for it to dry before performing color comparison; if the incoming sample is a wet sample, you can drop the sample into the color-matching paint to check whether the two colors are the same.

(4) Be vigilant and cautious when color mixing. Usually, you will first try a sample, start by finding the number of paints that should be matched, and then prepare a larger sample according to the sample effect. First, adjust the secondary color and secondary color separately in a small container.

(5) Because the colors often have different color heads, if it is matched with true green, yellow with a green head and blue with a yellow head are usually used; when it is matched with purple, blue with redhead and blue with the blue head should be used. Red; when matching orange, red with yellow head and yellow with redhead should be used.

(6) In advance, you should know the drift level of the original color in the double-color paint and the changing environment of the paint, especially the amino paint and the perchloroethylene paint, which need to be more detailed.

(7) It is necessary to be careful about which auxiliary materials should be added in the process of color mixing, such as the color of drier, curing agent, and thinner, so as not to affect the brilliance.

(8) Participate in the main color first (the color used in the color matching, the color with small tinting power), and then the dark color (or color matching) with strong dyeing power will be interrupted one by one, stirring constantly, and inspecting the color change at any time.

(9) When compounding multi-color paints, it is necessary to select paints with the same properties for mutual blending, and the solvent system should also be miscible. Otherwise, the poor miscibility of the paint will affect the wholesale quality of digital oil paintings and even cause signs of delamination, precipitation or gelation , Unavailable.

How to distinguish the quality of paint by numbers pigment

Now that there are so many DIY paint by numbers merchants, how do you distinguish the quality of paint? Below we will talk about how to choose good or bad paints in digital oil painting from nine aspects.

1. Gloss, the true meaning of acrylic paint does not need to use brightener, acrylic itself has luster, under what conditions will brightener be used? After the oil painting has been left for a long time, it can be restored to its original effect by wiping the picture with a brightener. Or in the process of drawing oil paintings with oil paints, adding some brighteners to the oil paints can make the colors of the paintings brighter. Because acrylic is a water-soluble pigment, it can only be dissolved in water, and the brightener is a grease product, which is not compatible with acrylic pigments.

2. Specific durability. How to judge whether the acrylic you used in photo paint by numbers is real acrylic paint or gouache? The method is very simple. A man friend can take off the smoking filter, dip a small amount of water, and wipe the screen. High-quality acrylic will not happen. For the phenomenon of discoloration, low-quality acrylic only needs to be wiped gently, and the discoloration will appear.

3. Observe and see if the acrylic paint has delamination. The so-called stratification refers to the thick deposit on the bottom of the container, and the upper part of the container is very thin liquid. This kind of acrylic paint belongs to the deteriorated acrylic paint and cannot be used. The above-mentioned situation will not occur even if high-quality acrylic paint is placed for 2 years.

4. Than elasticity. After the low-quality acrylic paint is painted, small hair-like cracks will appear on the screen after one month, while the high-quality acrylic paint will not appear. After the high-quality acrylic paint is painted, it will be elastic and gel-like, and it will be elastic when it is buckled by hand. If it is low-quality, it will become lumpy or powdery when it is buckled by hand. This is the "chalking phenomenon". ".

5. Price comparison, the price of high-quality propylene on the market is 300ml/12-15 yuan, some will be higher, low-quality propylene is not sold in the market, the price of gouache is between 100ML/1.3-1.5 yuan, so Customers and consumers are requested not to simply compare prices. It is more reasonable to compare quality and price comprehensively.

6. For examination use. When you don’t know about paintings or painting materials, it’s okay to find friends around you who have painted, and ask them as military advisers to advise you.

7. Covering power. High-quality acrylic paints have strong covering power, while low-quality acrylic paints tend to have poor covering power.

8. Color retention, high-quality acrylic paints are much stronger than low-quality acrylic paints. You can put the finished paintings drawn with different quality acrylic paints under the sun. After a long time, low-quality acrylics The pigment will fade.

To keep paint by numbers for two or three hundred years, the key depends on the proper use of oil painting materials, and the role of paint cannot be ignored.
