How to use pearlescent printing in cosmetic packaging?

In cosmetics, there are many types of printed packaging in pearlescent style. There are hard/cardboard outer packaging boxes, labels made of coated paper, plastic flexible packaging printed with pearlescent colors, and hoses printed with pearlescent patterns. These forms are often completed by different printing methods, and there are great technical differences between them. We cannot simply solve all problems with one solution, and due to space reasons, it is impossible for us to explain the various printing methods here.

However, there are some basic principles that we can grasp, such as a very important element when evaluating the effect is the pearlescent intensity. In printing, this is mainly related to two factors: the amount of pearlescent pigments and the arrangement of pigment particles. The former is easier to understand, the more pigments in the ink layer, the better the effect (of course, the gloss will not increase after a certain amount); the latter means that if the pigment particles can be arranged in parallel along the surface of the substrate, the intensity of the reflected light will be reduced. The best; in the same way, the smoother the surface of the substrate, the better the gloss effect.

In addition, when reconciling printing ink with pearlescent pigments, varnish (linker) with good transparency should be used, otherwise, after a large amount of incident light is absorbed in the ink layer, the reflected light will be weakened. For packaging products of different materials, considering the adhesion and operability of the ink, we will choose different printing methods. Manufacturers need to take into account factors such as product conditions, packaging equipment and costs. Of course, from the perspective of cosmetic packaging, visual effects and style come first.

How to use pearlescent pigments?

How to launch the next generation of products? How to plan the appearance of cosmetic packaging? This is a big problem that plagues manufacturers at present, and the larger the enterprise scale, the higher the brand positioning, the more cautious it is, and the more difficult the packaging design will be. On the other hand, the fierce competition in the market cannot tolerate the slightest miss, and once the opportunity is missed, it is difficult to find it back. There are many strong and unique manufacturers trying to get rid of the embarrassing situation and develop packaging in a systematic, efficient and scientific way. This is the inevitable orientation of survival and development in this industry.

From the perspective of high-end decorative raw materials, pearlescent pigment is such a product, which has wide adaptability, stable performance, and can provide a lot of options. Pearlescent pigments are traditionally referred to as white pigments that provide a soft, delicate pearl-like effect. But in fact, such pigments processed with mica have long been not limited to this. YORTAY's conventional pearl pigments are divided into four categories in terms of color, and five major grades in terms of thickness; they are not only different in color, but also very different in coverage and gloss characteristics. Foreign countries are gradually replacing the incomplete definition of "pearlescent pigment" with "special effect pigment".

What is so special about pearlescent pigments?

First of all, pearlescent is a deep, layered visual effect. The luster we observe is compounded by the multiple refraction of the incident light in the pearlescent coating. Therefore, the pearlescent coating exhibits a pearl-like texture and uncertainty of position. Secondly, pearlescent has translucency. Except for pearlescent pigments, there is no other color-forming material that can have a translucent "bone" and a perfect light-color effect. For this reason, pearlescent pigments can be color matched with other pigments to create more and fresher visual effects. There are two common types of color combinations:

A. A separate pearlescent color coating is superimposed with a conventional color coating. When the pearlescent color is on the top, it can reveal part of the color light below, and the gloss effect is best displayed. When the "iridescent interference color" pigment is covered on the dark background color, the characteristics of its refraction and color change and the background color will merge into a faint color, which is full of mystery. When the pearlescent color is below, it seems to form a high-brightness base color, adding saturation to the color above.

B. Pearlescent colors can be mixed with conventional colors to produce mixed colors. This combination also accentuates the color saturation in the pearly luster. It should be noted that since the pearlescent effect is a soft luster with low reflection intensity, excessive mixed color concentration will cause loss of luster, so we recommend that the selected mixed color has better transparency, and the addition amount should generally not exceed 3%. In addition, pearlescent pigments It has the effect of light color change: It refers specifically to the "iridescent interference color" pigment with "switching effect".

In order to describe the product more vividly and promote its use, the relevant market staff have analyzed and classified the characteristics and application concepts of pearlescent pigments, which can be regarded as a combination of inspiration and experience:

Soft & Care: An elegant, delicate silky luster formed by fine-grained pigments.

Young & Fresh: Refers to the fresh, bright and dynamic expression provided by medium or fine particle pigments.

Deep, rich (Dee-p&Rich): refers to the effective combination of pearlescent and conventional colors to form a good color intensity, harmonious color, so as to express the restrained and noble quality.

Aesthetic&Functional: The use of soft titanium pearlescent luster can just redefine the relationship between high-tech products and aesthetics.

The use of pure pearlescent colors in a large area can express a graceful and luxurious style. Everyone agrees on this point. If you have an in-depth understanding of this material, it is possible to exert its unique creativity and show wonderful ideas. Such as: SHISEIDO moisturizing cream packaging box is a typical case of using pearlescent pigments to show product style.

The use of pearlescent effects in cosmetic packaging is not uncommon, but most of them are based on light-colored bases, lacking further changes, and some are the same. This box is a little different. The light yellow tone is rendered on the pearlescent surface. This combination complements each other and adds a dash of natural sentiment to the overall style. In addition, the top varnish adopts Uv-type partial glazing, which makes a decorative ripple pattern appear on the moist pearlescent surface.
