Four Color Printing
The CMYK color model (process color, four color) is a subtractive color model, used in color printing and is also used to describe the printing process itself. Inks used in CMYK printing come in 4 colors: Cyan, Magenta, Yellow, and Black.
HalftoningPrinting with CMYK works in part through a process called halftoning (also called screening) allows for less than full saturation of the primary colors. Tiny dots of each primary color are printed at different angles to create the printed image and text. With halftoning, a full continuous range of colors can be produced.
AdvantagesIf it takes more than 3 colors to achieve a print reproduction, than 4-color printing will probably be most economical. CMYK printing is the most widely used and cost effective color system in commercial printing.
DisadvantagesSince the colors are a mix of dots over other dots, there is a good chance that color will vary from printer to printer and job to job. Ching Teng’s color management system can display good color quality in different substrates and keeping color consistent across different printing processing.
Comparison with RGB displayCMYK is used for printed media, while RGB is used for monitors, televisions, projection, and other light-based display technologies. The physical reality of printing requires using CMYK inks. If the artwork designs are made in RGB, it is required to convert to CMYK. Conversions are generally done through color management systems.
- Spot Varnishing
In addition to the common gold, silver, can also be printed with pearl, or shiny and texture effect under the light. Welcome for inquiry.Read More
- Keeping Color Consistency
Why the same artwork printed in different device and different substrates would have the color deviation? Do you understand and can describe "what is your color now"?Read More
