Many customers seem to have some doubts about printing of various packagings, such as the minor color difference between the of the printed colors and those of the artwork, the difference between the CMYK printing and the spot colors, etc., then our issue will focus on this type of printing. Below article is going to address such issues and other pre-printing knowledge.
Pre-printing, Printing, and Post-printing are the three major processes involved in modern prints. Each process directly affects the normal operation of the subsequent ones. Success of packaging printing product cannot do without the scientific and reasonable each-stage processing design.
1. Spot color printing:
It refers to printing a certain Pantone color with a special pre-mixed ink, which is brighter in effect than the mixed color of four colors(CMYK), in offset printing. Any specific spot color can be realized, but gradient colors cannot be achieved through spot color printing. If necessary, CMYK 4C printing can be added. Besides, for large-area dark-color prints, it'll be difficult for CMYK printing process to achieve desired effect. Because the ink layer will too thick (with multiple overlays of color ink), while the spot color printing process only needs print one color.
2. CMYK 4-color offset printing:
The so-called four colors are: cyan (C), magenta (M), yellow (Y) and black (K). All other colors can be mixed by these four inks, and finally achieve a colorful print. It is the most common printing process, though the effect printed on different substrates is different.
