The process design of carton packaging

The carton packaging production process has been very mature in the packaging and printing business, from the box template design, prepress, to color selection and application; from plate output, printing, to surface finishing; from embossing, die cutting, to paste box, the entire scheduling process, process control, has been able to meet the basic requirements of the carton packaging production. But we know that the carton production, after all, different from other printing products, there are strict requirements of the process design, process management, improve the level of system management, strict process discipline is the premise of guaranteeing quality.

1. the types of carton packaging

There are more and more species of carton packaging according to their widely usage. Corrugated boxes, laminating box, cardboard boxes, from the box template structure it has lock bottom box, lock end box, double-wall boxes, irregular shape boxes etc.. These ever-changing shape of different cartons, with the development of new products, I believe there will be more forms, functions of the carton packaging.

2. Paperboard selection

Mostly carton packaging used cardboard material, generally 210 ~ 450g/m2, including duplex white version of the paper, white paper, white cardboard, composite cardboard.With the paper weight changes, the performance increases, which requires for a reasonable choice according to the requirements of different customers, different types of products and product features. It is necessary to maximize the protective effects of the product, it also enabled the costs to a minimum.

3. Process design

The process design of the carton packaging is a complex task, which includes pre-press production, printing, surface finishing and carton forming. If the process design is not careful, imperfect, not only a waste of raw and auxiliary materials, the product quality can not be guaranteed. Therefore, we must be familiar with the problems that may arise in the process and eliminate them before the prepress production, in order to provide fully qualified for the printing plates. We know that the carton packaging design usually with two-color printing process, high, eye-catching, unique is the basic form of expression of the carton, in the network settings to meet the characteristics of the carton packaging.

From the point of view of the printing process, the use of color is based on the printing ability to faithfully restore is the primary consideration, but in view of the printing equipment, technical standards, and the instability of the process control need more consideration. Carton color consistency, there are strict requirements of our multi-path which open up spot color in order to achieve the perfect color reproduction, this process has been adopted by more businesses.

The step and repeat process is related to the key of the paper utilization, reasonable step and repeat to maximize the utilization of paper, has great significance to reduce costs. Ensure that the box wire lock at the same time - like a box template greater use of technology embedded fight This will not only save paper and to improve production efficiency benefits. To special regulation-sized paper for the multi-linked printing has become the choice for enterprises to create a better economic benefits.

4. Proofing test

Proofing Is an indispensable part of pre-press. First, check the color settings to restore the situation to provide accurate process for the production of information; Second, the accuracy of the check image and text so that contents of the file in full compliance with customer requirements; Third, check whether they can adapt the production process to prepare for the batch production; its four box template structure is able to meet user requirements; impact strength test of the box body is also essential. The ultimate goal of the inspection process design elements rationality to solve existing problems, to prevent the imperfect aspects of potential impact to the production of the product. These seemingly simple, in fact, flow control, error prevention has important practical significance. Then it is the carton packaging finishing process, it includes laminating, UV light, hot stamping and embossing, different finishing effect to meet different customer requirements.
