Spot color printing(专色印刷) is a printing process involved in offset printing, using a spot color ink (pure or mixed) specifically formulated according Pantone code. It’s a single and extra run other than the general CMYK 4C printing process, and thus requires its own lithographic film.
Then on what occasions is spot color
(1) When the cardboard gift boxes
designs involve gold or silver color. Golden and silvery colors differs
greatly from rest colors and are extremely opaque. Thus they are impossible to
realize on the print by regular CMYK offset printing process. In this case, spot
color printing can be used to achieve golden or silvery tones (An alternative
method to foil stamping).
(2)The prints often comprise uniform color areas
of varying gradient colors and text. These color areas and texts can be achieved
either by the process of registering in offset printing or by spot color
printing. With comprehensive trade-off between improving print quality and
saving the runs of registering, it is sometimes necessary to use spot color
printing (An alternative method to registering).
Spot color printing uses a non-standard offset ink such as metallic, fluorescent, or
hand-mixed ink. Every color needs one lithographic film and an extra printing
run. Also, the potential for problems will generally increase. All these will
be factored into the total cost of the final gift boxes.
