If you are designing color box packaging and science books for your STEM business, then this article is perfect for you to read.
What are RGB, CMY, and CMYK?
RGB: RGB stands for “red, green, and blue.” These are the three primary colors that can be mixed together to create all other colors.
When all three sub-colors are combined, we see white light. The RGB color model is used to create all the colors on your computer screen or TV. It’s also used in digital cameras, scanners, and printers.
In RGB, each RGB device uses three primary color lights (Red Green Blue) that can be combined at different intensities to produce nearly any visible color. When you look at your monitor, the RGB light coming from it mixes together inside your eye and produces the color you see on the screen. The only RGB device that emits pure color is a laser; all other RGB devices use some combination of fluorescent phosphors or light-emitting diodes (LEDs). RGB monitors display images by combining red, green, and blue light in varying intensities to produce millions of different hues on your screen. Every color on your computer screen or TV can be described as some combination of these three primary colors.
CMY: CMY is based on a white medium. By printing inks in different proportions of the three primary colors (cyan, magenta, and yellow), it absorbs the corresponding wavelengths in the original color light, so as to obtain various color reflection effects.
CMYK: In theory, CMY can mix K (black), but people find that K (black) is used a lot in practice. If you often need to use CMY to mix K (black), it means 1. Waste ink 2. It will be inaccurate, especially the small text, even now can not be completely inaccurate. 3. Printing with 3 kinds of ink, it is not easy to dry, so people introduced K (black)
What is Spot Color?
When printing, instead of printing C, M, Y, and K four-color composite colors, a specific ink is used to print the color.
Spot colors can be any color in the world, C, M, Y, and K can also be regarded as one spot colors. The colors used for mixing can be red, orange, yellow, green, cyan, blue, purple, white, etc. There are so many kinds of colors in the world, so how do I let the other party know what color I want?
PANTONE lists a small part of countless colors, labels these colors with color numbers, and distributes them all over the world so that even if you communicate with overseas suppliers, you only need to tell the color number on the color card, they can print accurately.
What Is The Difference Between RGB And CMYK?
RGB and CMYK are both systems for creating colors, but they operate in very different ways.
RGB is an additive system, which means that it starts with darkness and then adds light to create different colors. The three primary colors in RGB are red, green, and blue, and by combining these colors in different proportions, it is possible to create a wide range of hues.
In contrast, CMYK is a subtractive system, which means that it starts with white light and then subtracts certain colors to create the desired shade. The four primary colors in CMYK are cyan, magenta, yellow, and black. When combined in the right proportions, these colors can produce a wide range of tones. For example, by adding more cyan, it is possible to create a bluer color, while adding more magenta will result in a pinker shade.
RGB, or red, green, and blue, is used for digital displays, such as TVs and computer monitors. CMYK, or cyan, magenta, yellow, and black, is used for print projects like packaging, books, magazines, and business cards.
The main difference between RGB and CMYK is that RGB uses light to create color while CMYK uses pigments. This means that RGB colors are bright and vibrant while CMYK colors are more subtle.
Which One Is Better For Toy Box Packaging Printing?
Is CMYK or RGB better for printing? The toy packaging printing industry has been using the CMYK color model for a long time. The printers use four colors of ink—cyan, magenta, yellow, and black to create full-color images.
The advantage of this approach is that it can produce a wide range of colors, including those that are difficult to achieve with other color models. CMYK can more accurately reflect the way that human eyes perceive color and achieve the most accurate and consistent colors. Additionally, CMYK is more forgiving of slight color variations, which can be important when trying to achieve consistent results across a large print run.
If your artwork is in RGB mode, remember to convert to CMYK mode before printing.
How To Convert Between RGB And CMYK
It’s easy to convert between RGB and CMYK. To do this in Photoshop, go to Image > Mode > RGB or CMYK. Keep in mind that converting between color modes can sometimes result in a slight change in color. So if you’re working on a science box project, it’s always best to choose the CMYK color mode from the start.
Why Did The Printer Tell You That Many Colors Cannot Be Printed?
First: The Number Of Colors
Everyone knows that the RGB value is in the range of 0~255, there are 256 levels in total, and there are three colors in RGB, so in theory, the total number of RGB colors is 256³=16,777,216 kinds.
The CMYK value is in the range of 0~100, there are only 101 levels, and there are only three CMY colors in total, plus a special K, so in theory, the total number of CMY colors is 101³+101=1,030,402 kinds.
16,777,216 is more than 16 times different from 1,030,402.
You can use spot color inks to print the color you want. Printing with spot color inks will cost more than printing with CMYK inks, which requires a trade-off.
As a scientific toy brand, you already know which color mode is more suitable for toy packaging printing through this article, which will make you more professional in the communication process with Chinese scientific toy suppliers and printing suppliers. Any comment is welcomed.
