How to get the correct label appearance on glass or plastic containers

first of all, we should know the customer's expectations, the characteristics of the container itself and what it contains

the customer's criteria generally include: whether the printing color of the label meets the requirements and does not appear to have an obvious effect of pasting the "label". The appearance of non label means that the image is completely "integrated" into the surface of the container, and the label seems to have no thickness. Labels printed directly with silk, decorated with heat transfer, and processed by mold can produce such appearance effects. In other words, 90% of customers want to achieve this visual effect

in many cases, customers will use numbers in PMS (Pantone color matching) to identify the color they need. 4. The intention of upholding the advanced, sticking to the right path and righting the universe is to hope that the label can match the color of the container, so that the ideal requirements can be achieved when observing the label on glass or plastic containers

gloss level (from high gloss to matte) will also affect the label color observed by human eyes. Similarly, the objects in the container will also affect the color, especially for transparent and translucent containers

label manufacturers should select some containers full of items or prototype containers as the quality inspection standard in order to let customers recognize the labels they produce at one time as much as possible

according to incomplete statistics, there are eight application combinations of container and label surface materials in the market, which have a certain impact on the image effect of the label. They are:

container type label surface materials

1 Transparent transparent

2 Transparent and opaque

3 Opaque transparent

4 Opaque opaque

5 Translucent transparent

6 Translucent opaque

7 Matte transparent

8 Matte opaque

transparent labels are used on transparent containers: in this case, the transparency of surface materials, the wetting characteristics of adhesives, the color of objects, the glass, ink and coating of containers are all factors that affect the final effect. The most common containers are made of glass, pet, PP and polycarbonate

use opaque labels on opaque containers: in this case, the gloss of containers, the color of containers, the opacity of surface materials, and the gloss of inks and varnishes need to be considered. The gloss of opaque containers varies greatly. The most commonly used opaque containers are made of HDPE, which have low gloss; On the contrary, the gloss of PP material is higher

use opaque labels on translucent containers: most translucent containers are made of undyed HDPE material. In this combination of labels/containers, the most representative examples are milk bottles and medicine bottles. At this time, the gloss of the ink or varnish is very important to match the container. If the container contains dark objects, it will seriously affect the color matching on the container

using transparent labels on matte containers: this application is difficult and requires high skills. Because the rough surface on the container may come from slight acid corrosion or coated with a thin chemical coating. I have seen such a situation: the adhesive with excellent wetting performance makes the area behind the label become a transparent, and the versions shown are effective windows. In this case, the wettability of the adhesive should be low

the above four situations give us a perspective on the factors affecting the quality of labels: Coke 1501 weak shock solution. The following table lists the various influencing factors in the use combination of these eight containers/labels

there are two conditions to successfully print labels on glass and plastic containers: first, have a good understanding of customer recognition standards; Second, it can provide qualified containers filled with appropriate products. Without either of these two conditions, qualified products cannot be produced
