The way people see colors can vary, depending on the structure of the individual's eye. This is especially true in the range of blue bands, which can also affect each side when placed next to another color. Possible through reflection or as a visual illusion. To prove this, keep a piece of light paper or object next to a piece of white paper near a light window, the piece of paper will turn into another color. Bright colors will have different effects on different objects.

This is very clear in the case of bright colors, especially dark colors or complex colors (colors are made of cyan, magenta, yellow and black (CMYK) all mixed with together).

3. Common tool for color testing

You can check a standard color CMYK for offset printing sold at the foreign bookstore, or for a Pantone color book, which is relatively common. There are many other color books issued by the companies that follow their ink system.

On the color plates they have the same colors as the indicators to print the color such as red C0 M100 Y100 B0: Means blue and black are not available, pink + yellow prints 100%, similarly With other colors. This is also known as color, Pantone color also shows how color on paper or glossy paper matt or unmatt. You compare the color to print with the standard color book to get the color parameters into the design program and outfilm.

For offset printing with good printers and standard cartridges, color is right, and low quality printers or the effect of standard color output will change a bit. So when producing large quantities, stand next to the printer, ask the printer adjust the standard for the required color relatively. If the exact color requirement is about 99%, then print the color phase, ask the brewman the right color and then print this way often for net printing or offset zinc printing.

4. Web page color compared to the color of print

The color of the company logo or any other graphic element on your web site may differ from the colors on your printed materials. The reason sites use the RGB color system (Red Green Blue) in their graphics for the screen. You and your client should unify the color palette to work with the web screen.

Use of colors is available through the Pantone Color System (PMS Color). The printer combines the colors to the exact specifications as in the Pantone book, so you know exactly what the colors will look like on the finished product. However, this method only allows printing to print in one, two, or three colors and can cost more when there are four-color, digital printing methods available today. However, many print services only provide color palettes on certain types of paper. Print Press with Pantone color standards allows you to choose a wider color range with paper materials, then add a new color element to your document.
