So far, printing quality control has gone through a shift from "quality is detected" to "quality is manufactured", and then to "quality is designed". This fully reflects the importance of reasonable process design to achieve excellent printing quality. As a result, some larger label printing companies have delegated this task to separate teams or individuals.

In recent years, some high-end labels have been completed through combination printing. Combination printing is a combination of various printing processes such as flexographic printing, gravure printing, embossing, screen printing, offset printing, etc. Therefore, the design of label combination printing process involves many issues. If not fully considered, it will affect the final printing quality. To do a good job in the process design of label combination printing, the author believes that it is necessary to first understand several necessary factors of printing: printing material, ink, printing plate, printing machine, and then design a reasonable process flow based on the performance matching of these factors. Below, we will discuss the design points of the label combination printing process based on these factors.

Printing material is one of the important raw materials for label printing, and its characteristics directly affect the quality of the printed product. When choosing the printing material for label combination printing, label printing enterprises must choose the optimal printing material based on the specific requirements of customers, combined with the purpose of the label, the usage environment, and the production capacity of printing equipment, while controlling costs.

1. Select the printing material based on the characteristics of the object to be pasted.

If the label is pasted on a spherical object, do not choose materials with high stiffness, but choose soft materials such as paper or film materials. There is a case where a certain company chose transparent BOPP film for aesthetics when printing a batch of drug labels. However, due to the high stiffness and poor follow-up of BOPP film, the label edge "curled up" phenomenon occurred shortly after labeling. Finally, the problem was solved by using copperplate paper to print the labels. Of course, for cases where a transparent adhesive material with higher stiffness has been chosen, the perfect attachment of the label to a spherical object can also be achieved by changing the adhesive used in the material.

2. Select printing materials based on the purpose of the label.

If the label pasted on the hose is frequently compressed, it is advisable to use PE materials that can withstand a certain amount of pressure; The label of cleaning products should prioritize the use of membrane waterproof materials, or achieve waterproofing by covering paper materials with film.

3. Consider whether the selected printing material can be printed on a combination printing equipment.

Combination printing equipment has strict requirements for the substrate material. In addition to the thickness and width of the substrate material, there are also high requirements for the stretchability of the substrate material due to the influence of tension between different units.

4.

Low cost materials should be selected while meeting usage requirements to reduce unnecessary waste.

In short, the selection of printing materials should meet the requirements of customers, and label printing companies should provide customers with the most perfect printing material selection plan for their reference.

There are many types of ink for label printing, and when choosing, factors such as the purpose of the label, the type of printing material, printing process, and printing conditions should be considered.

Firstly, the purpose of the label is the most important factor in determining the ink used. Labels used outdoors should withstand the test of wind, sun, and rain. When choosing ink, attention should be paid to its light resistance, water resistance, high temperature resistance, and other properties; The labels used for cleaning products are prone to contamination and corrosion from solutions, so it is required that the ink must have good acid, alkali, and oil resistance.

Secondly, printing materials are also one of the important factors affecting ink selection. Different inks have different transfer properties and their presentation effects on different substrate materials are also different. Therefore, ink that matches the substrate material should be selected.

Again, ink should also be compatible with the printing method. Generally speaking, the inks used in embossing, gravure printing, offset printing, etc. are different, and there may be incompatibilities between different inks, resulting in issues with overprinting rate and adhesion. In addition, ink can sometimes be incompatible with other post press finishing processes. Therefore, before combining printing, it is necessary to conduct compatibility testing on the ink and obtain necessary technical support from ink and other consumables suppliers.

Combination printing integrates multiple printing processes, so the production of printing plates is also an important task. Of course, making printing plates based on customer design requirements is a key principle to adhere to.

In order to ensure that the printing color effect meets the customer's design requirements, during pre press plate making, it is necessary to first perform graphic design on the customer's original manuscript. Based on a comprehensive evaluation of the accuracy of the combined printing equipment, appropriate trapping treatment and dot increase compensation should be applied to the printed graphics and text. When separating colors, in addition to arranging the color sequence, special attention should also be paid to color masking. For example, for labels pasted on black objects, a white background should be placed under the 4-color pattern to reduce the impact of the pasted object on the label. Then, choose the appropriate plate material based on the printing process, such as paying attention to the softness and hardness of the resin plate, and the carving method of the gravure plate.

Nowadays, many manufacturers can provide printing equipment with multiple process combinations such as offset printing, embossing, and screen printing, and achieve the best printing effect by leveraging the strengths and avoiding weaknesses of various printing methods. But in order for label printing enterprises to truly make good use of combination printing technology, they also need to pay attention to the alignment of multiple processing process designs, and regularly monitor the printing curve status of the equipment to ensure the printing capacity of the equipment, in order to better reproduce the design effect of the original manuscript.

In short, label combination printing combines multiple printing methods, with complex processes and strong technical requirements. Label printing enterprises are required to meet the ultimate needs of customers, select appropriate printing materials, inks, and plates based on the printing equipment's printing capacity, and control various parameters internally to ensure smooth production in the future.
