Why Does The Transparent PET Box Change Color Or Fade When Printing?

In the current market situation, color box packaging is most used in sales packaging, among which transparent PET boxes have sprung up, occupying a place in the packaging market. Compared with ordinary carton packaging, transparent PET box packaging is richer in color and more delicate in appearance, and it is easier to attract the attention of customers in many packages in the sales market.

However, if the color of the transparent PET box packaging is unreasonable in the design, the effect will be more than the loss. Therefore, the reasonable application of color in the packaging design is one of the main factors for whether the transparent PET box packaging can excel in many products. So how to use color properly?

The color of the outer packaging should correspond to the hue of the product it is packaged in. transparent PET boxes are widely used in sales packaging because it can more directly express the appearance of the product, allowing users to see the appearance and application effect of the product according to the packaging, thereby increasing the sales volume of the product.

If the color box packaging is used as a sales package and the application of its color cannot correspond to the color of the packaged product, it will cause customers to fail to recognize the characteristics of the packaged product, and the color box will be difficult to achieve marketing effects.

How should we choose the appropriate color when developing the color design of the color box packaging surface? In terms of field, food packaging products generally use light yellow and pink as the dominant colors, giving people a warm and intimate feeling.

While tea is mostly green, drinks are mostly green and blue, wine and dessert products are dominated by rose red or red; clothing, shoes and hats are mostly dark green, dark blue, coffee or dark grey. Light pink, light green, light blue, and dark brown can be used to highlight the warm and elegant interest of transparent PET box packaging, thereby highlighting the calm and elegant artistic beauty.

transparent PET boxes can allow customers to directly see exquisite products and stimulate their desire to buy. This kind of transparent PET boxes will change color during the packaging and printing process. Why? This makes many people particularly unbelievable. Let's take a look at the reason with cholyn.

In the process of packaging and printing the transparent PET box, the ink after drying is compared with the ink that has just been printed. The ink color of the ink after drying is lighter than that of the ink that has just been printed. In this problem, the key factor depends on the discoloration caused by the penetration of the ink on the surface of the pvc plastic box and the oxidation of the conjunctiva during the drying process.

The letterpress ink is dominated by infiltration and dryness, and the ink layer is relatively strong. At this time, it will take some time for the infiltration and oxidation of the conjunctiva to dry out. When the transparent PET box is packaged and printed, the ink color should be controlled at a slightly darker level than the printed sample ink color. When the ink is dry, the color specification of the sample ink color will be achieved.

Specifically, the packaging and printing inks of all PV color boxes will have different levels of fading and discoloration after exposure to light. After long-term direct exposure of the light source, the lighter color ink fades and the color change is serious. In the case of ink adjustment for transparent PET box printing, ink with good light resistance should be used as much as possible; at the same time, the consistency of light resistance among several types of inks should also be considered when formulating inks.

The same is a dark blue ink, phthalocyanine blue is more light-fast than light sea blue and lake blue, and it is not easy to change color. If you add a little white ink, the color will be more gorgeous. If you use lake blue and iron oxide yellow ink, it is very easy to fade, change color and yellow over time.

The above is the reason for the discoloration of the transparent PET box during the packaging and printing process. It has an important relationship with the reasons often mentioned above. After this explanation, do you all understand it?
