Six-color process printing is another method of color printing too involves addition of orange and green shades to the traditional CMYK color scheme, making possible other vibrant color combinations.
However, a line of steps are involved in the color printing process to generate a quality color reproduction. Color separation is the several primary step, which is accomplished with the make it easier for of digital imaging technology wherein the original artwork is digitally scanned and separated into red, green, and blue components. Digital imaging technology has been very important in faster and higher quality color separation. The process has eliminated the drawbacks of the traditional method, that was to photograph the image three times, and then a different filter was used for every color.
After separation, the images are inverted, and then, by black separation, an image amid better contrast and shadow is reproduced. The final step is screening of the image in required colors.
The Stochastic screening method is the newly written process in this direction, that greatly facilitates in eliminating the dots that are generated by the traditional half-tones screening processes.
Color printing can be reproduced with the help of various printing techniques, these types of as offset lithography, screen-printing, digital printing, flexography, and gravure. The offset lithography is done mostly by all printers and is considered one of the main methods. On the other hand, screen-printing is the most popular process and is useful in a variety of printing operations.
