Pantone color ink refers to a specific
color ink to be mixed in advance, such as fluorescent yellow, pearl blue,
metallic silver ink, etc. it is not mixed by CMYK four colors, and the color of
the set means accurate color. It has four characteristics:
1. accuracy
Each color set has its own fixed color
phase, so it can ensure the accuracy of the color in printing, thus solving the
problem of color transmission accuracy to a large extent
2. field nature
Pantone colors are generally defined by
field colors, regardless of how light the color is. Of course, can also add net
to pantone color, to present pantone color of any depth and light tone;
3. opacity
Pantone color ink is a kind of ink with
covering nature, which is opaque and can be covered on the spot;
4. wide color range
The color gamut in the color library is
very wide, which exceeds the performance color field of RGB, let alone CMYK
color space, so a large part of the color can not be presented with CMYK
four-color ink.
The reason why pantone color is chosen in
color dot printing
In the color dot printing, it is often used
to select and use the characteristics of pantone color ink. Generally speaking,
it is generally used in two cases:
1. In book printing process, to print some
visible light colors other than CMYK four color printing ink on the printed
matter
The color domain of CMYK four-color
printing ink has obvious deficiency compared with visible light color field,
while the color field of pantone color ink is wider than that of CMYK
four-color printing ink, so it can show many colors other than CMYK four-color
printing ink.
2. to make up for the shortage of book printing technology
Due to the errors of each process, equipment
maintenance, working environment, omission and mechanical wear in the whole
printing process, it is difficult to get even dot color when printing small dot
below 153. At this time, we can replace small dot with full plate color (pantone
color field) of the same color to print, and then we can easily get flat large
area color block . In addition, in order to clearly express fine pictures, such
as fine mixed color graphics and pictures or albedo lines, special color
processing is often used to make fine line strokes more realistic and delicate.
Some problems to be paid attention to in
the use of pantone color before book printing
unification of pantone color name
In different software, the names of the two
sets that are identical may vary. For example, freehand names pantongei1f
Pantone 1f5cvc or panion1f5ccvv, while PageMaker is named Pantone 1f5cv. In
this way, when freehand graphics objects are placed in PageMaker for
typesetting, the same color will have three names. When color separation output
is output, three plates will be generated, resulting in output errors.
Therefore, if the data file needs to be used in more than two software, it is
necessary to note that the same pantone color name must be unified before the
integrated color separation output. The more common method is to take the color
names in the distribution as the standard, and rename the names of the same pantone
colors in the palette of various software as the unified names.
