Technical Communication: corrugated boxes also need to color management - color management, cartons - Printing Industry

Color is the color of the same product and the gap between standard samples. Color gradually become the focus of our customers and become a barrier of market competition, a packaging and printing company's brand, an enterprise of a two-edged sword fight in the market. In fact, customer requirements have been imposed on the color for packaging printing enterprises, this is a double-edged. Color control, and can be to defeat rivals, if not properly controlled, then, will meet the customer complaints, returns, or even the market ruthlessly eliminated.

The prevalence of the sales package to promote the role of its advertising is getting its protection. Therefore, the customer requirements of product color will be more specific, or even digitization. However, China's national standard corrugated boxes no clear requirements for this project, but most refer to the "offset printed decoration" in the color requested. But in terms of corrugated packaging, does some far-fetched. According to the author's observation and conclusion, color corrugated box products are divided into three situations:

Color difference between the same batch of product GB/T2828.1-2003/ISO2859-1: 1999 provides: grant that would bring together a number of products, materials or services (or known as the implementation of the pooled sample test of the unit product). Continuous and isolated sub-grant award approved. Continuous production process in the same series of batch production, as long as the product of the design, structure, process, main raw materials and other production conditions the same, namely, continuous batch. Can not be approved for the continuous isolation of the batch as batch, such as a single batch, batch and so few. Our actual production, there are often both. Color difference with the standard approved in GB/T7705 in 2.4 this has been provided in table 5: Eab less than 5.00.

Color between different batches Between different batches of product color differences. National standards or industry standards No it clear that the general license in accordance with customer requirements to develop the scope of (some clients develop color depth, in light of the three standard sample). Although this standard can be artificially relaxed some, but now consumers demand increase, businesses will never allow a larger color display their products in the supermarket counter. Therefore, some different batches of color standards and the same batch as the same color. In fact, the standard is very challenging.

Among different color package printing factory This color difference is mainly raw materials supplies, staff technology, production environment, the different result, can be said that any part of the difference may have resulted in the color packaging. Color range of products of different manufacturers generally slightly wider than the other, but it is also very limited.

For the understanding of color, first, from experience, observation, and second, by measuring instruments. Most enterprises now relies mainly on the first approach, using UV Density Density or detection of the business or rare. Well, two ways one is better then? The author believes that: the color of understanding, these two approaches have short feet, inch a director. Empirical observation of the weaknesses are: instability, human visual changes with the external environment, physiological changes of mood change, is likely to result in printing color difference. The spectral density instrument, relatively speaking, the more scientific and stable, but high cost, and now the printing corrugated lines lower, larger networks, the different measurement methods will result in large errors. But, according to corrugated packaging development, the color data measurement and data management is the trend.

So how do we reduce the carton in the color it? Stable quality ink

Stable color ink quality is a key factor in control. This is because the many customers in order to promote the uniqueness of their products and increase security features, will select the modulation spot color inks. The ratio of spot-color ink must be accurate, so as to ensure the stability of ink hue, lightness, saturation meet the requirement.
