In everyday life, you often encounter beautifully colored, high-quality removable sticker labels in supermarkets and shopping malls, which usually trigger your purchasing impulse. The design of the labels is crucial. With that in mind, we at JiuRong will now delve into the topic of colorful printed labels.

The general characteristics of label printing products are: vibrant colors, large contrasts, and they stand out when applied to products, offering a prominent storage shelf effect. In contrast, general color printing emphasizes clear patterns, strong sense of depth, detailed tones, and a rich variety of colors. Therefore, label printing requires special printing techniques.

Label printing machines typically feature four colors or more, with twelve-color printing being quite common. The layout design of labels usually combines spot color printing with three-color printing methods. As a result, high-quality labels often have frequent printing, with the actual location or title text printed in spot colors, while character images are chosen for four-color process printing. Even for the same color tones, both on-site and online lines are printed in two stages to achieve a very impactful visual effect. Generally, full-color printing is conducted on printing machines using four-color printing.

The printing machines applied are for solid-color, four-color, and two-color printing. If the labels are printed using screen printing, the on-site graphics, outlines, and text on the label are printed together with the tonal gradation on the same plate. Due to the limitations of screen printing, the lightness of the inks and the working pressure of each part are consistent, making it difficult to reflect the characteristics of label printing on the finished product labels. Generally, the spot colors and graphics on regular printing machines are made from flat-screen spot colors, while label machine printing is done with spot ink, resulting in different actual effects.

The styles of label printing products are designed based on the characteristics of labels, and label printing machines are specifically designed for label printing schemes. Currently, high-quality self-adhesive labels are all printed using label machines with six colors or more.
