Before talking about the application products, visual effects, printing costs, etc. of four-color printing and spot color printing, let’s first understand the basic printing colors.
1. What is four-color printing?
Four-color printing generally refers to the printing process of using yellow, magenta, cyan, and black ink to print various colors of color pattern manuscripts.
2. What is spot color printing?
Spot color printing refers to the printing process of using other color inks other than yellow, magenta, cya,n and black ink to print the color of the pattern manuscript, such as green, gray, etc.
3. What products are suitable for four-color printing?
Photos taken in the form of color photography that reflect the colorful color changes in nature, colorful art works of painters, or other pictures containing many different colors, will be printed using four-color printing technology for technological requirements or economic benefits.
4. What kind of products will use spot color printing?
The pattern itself has high requirements for color, and the color mixed with four colors cannot meet the requirements of the effect, so it is necessary to equip the spot color, which is more to improve the quality of the printed product.
5. What is the difference in the visual effect of the color block of spot color printing and the color block of four-color overprinting?
The ink mixed by spot color printing is obtained according to the principle of color material subtractive color mixing. Its color brightness is low and saturation is high. The change of ink layer thickness will reduce the sensitivity to color change, so it is easier to get a uniform and thick printing effect.
The color block is mixed by the four-color printing process because the various colors that make up the color block are mostly composed of a certain proportion, any change in any color will cause the color of the color block to change, resulting in the chance of uneven ink color will be doubled, and it is not easy to achieve a uniform ink effect. The color block has a higher brightness and a lower saturation.
6. From the perspective of economic benefits, what kind of products are suitable for spot color printing?
It mainly depends on whether the spot color printing can meet the requirements of the product pattern. If it can, then choose it; if the effect of four-color matching does not meet the requirements, then you must consider using spot colors.
7. Can a product use four-color printing and spot-color printing at the same time?
Yes, if both are used, they are generally used in high-end and high-standard printed products. In order to pursue better quality, although it will increase costs, the added value is higher.
