Professional knowledge that printing practitioners must know-printing color

        Printing or printing color cast is the biggest headache for designers when outputting. The printed materials we see are composed of three elements: light, paper and ink. When the budget is tight or when specific colors are used, monochrome printing is used. For example, many brands or companies use specific Pantone colors in their printed works, which can effectively maintain the color uniformity to ensure the color recognition of the brand. It is recommended to buy a Pantone Chromatogram and choose the relative color number for printing.

Two-color and three-color printing allow Pantone colors to be mixed, overprinting two transparent inks can produce a third color, and printing black and white images in two-color and three-color can enhance the color effect.

Four-color printing is known as CMYK, cyan, magenta, yellow, and black, and countless colors can be created according to the ink ratio. This is what we are most common now.

Pantone System: The Pantone Color Matching System (PMS) includes a color reference manual and a color matching guide. You can select the Pantone color code or input the exact CMYK value to select the color. The printer comes with these guidelines and matching inks, so you need to see Instructions.

Pantone colors are also commonly known as spot colors, and there are many colors to choose from, but we know that the colors will vary with different paper effects. In order to get the color closer to the design, there are many versions of PMS color samples for different papers, including matte paper, copper plate, etc.

Calibrate the detector: First of all, this designer can understand it, because this does not require us to operate. Correct calibration and use of configuration files can get infinitely close to the colors you see on the screen. Many modern monitors are equipped with presets and programs that can help us obtain basic values. In recent years, colorimeters for confirming each color point have become readily available. The colorimeter is cycled in many different modes to read the current state of the display and adjust the video card correctly, thereby creating a new ICC configuration text.

Is it complicated? Yes, the problem of color correction is a boring little fairy. If you meet an experienced master in a printing factory, he can help you handle everything. If not, use spot colors obediently. The screen color is not always accurately printed out, so when printing the finished product, remember to try a few more times and make a few samples to make sure that it is correct and then print in batches.

The color matching problem that many people encounter is RGB and CMYK. RGB is the screen color, and CMYK is four-color printing. The RGB color cannot be printed. You can only use CMYK to adjust to a close color, so remember to change it before printing. Convert the file to CMYK format, otherwise there will be problems when passing the printing press. There are friends who print in small batches and can only print at a digital print shop. At this time, the color cast is inevitable. You can only try to get as close as possible to the effect you want. Experienced friends know the CMYK ratio. But friends who are not in contact with printing much, it is recommended to go to the print shop to select the paper and make a sample. If not, bring the source files and change the value on the spot. It is best to ask the staff for help. They are familiar with their machines until they are satisfied.

Little Tip:

black

Many designers like to use a large area of "element black" or "super black" color scheme. This color scheme is C60 M40 Y40 K100, which is used for images, not text. Compared to K100 pure black, this color scheme is more comfortable.

Spot color

The fan-shaped sample guide contains more than 1,000 Pantone spot colors, and there are special versions of gold, pink, luminous colors and so on.

Color scheme

There are more than 3,000 kinds of Pantone printing colors in the guide book, equipped with CMYK hue percentages. The guide was formerly called the Pantone four-color simulation spot color guide.

Pantone

In this guide, the Pantone code ending in C indicates the color that only matches the glossy coated paper. The Pantone code ending in U is expressed as a printed color matching the matte paper surface.
