Do you want to make prints more like it? Learn how to manage the color of flexible packaging prints

[China Packaging Network News] Before printing on flexible packaging, it is necessary to carefully analyze the hue of the original. This article will introduce the analysis of the original hue from the two aspects of why it is necessary to analyze the hue of the original and analyze the hue of the original.

Why analyze the hue of the original?

It is assumed that the green ink is formulated with the blue ink and the yellow ink. If the blue ink has a red phase or the yellow ink has a red phase, the green color obtained by the mixing will be dark. Because this is actually equal to the addition of magenta ink to the blue and yellow inks, and even if there is little magenta in this part, the same amount of cyan and yellow should be mixed into black by the principles of subtractive colorants (yellow+cyan+magenta). = Black). When a small amount of black is added to the green, its color is of course darkened, and the brightness and saturation are also greatly reduced. Therefore, if you want to use color when printing, you have to analyze the hue of the original.

Analyze the hue of the original

When analyzing manuscripts, the color of the manuscript and the ink used are mainly analyzed. The principle is: the primary color is the basic color of all inks. No matter how complicated the color is, no matter how it changes, the range of the three primary colors will not exceed the range. .

In the analysis of the manuscript, it is necessary to make it clear as far as possible whether the manuscript is based on network printing or on-site printing. If you use network printing as the main method, you should focus on the same color when you are mixing inks; if you mainly use on-the-spot printing, you can focus on the same color on the deployment; if both are combined, then the color and color of the ink when the ink is mixed It is necessary to take into account.

After the color draft is analyzed, the color of the used ink should be analyzed, that is, for any kind of ink, one must be good at seeing the color components. For example, for yellow inks, be good at discriminating whether it has a red phase or a blue phase (or green phase); for a magenta ink, be good at identifying whether it is a yellow phase or a blue phase (or a purple phase); for blue Ink, it must be good at identifying whether it is with a red or green phase (or with a yellow phase).
