As shown in Figure 1, Lab colour gamut is the colour gamut of the theoretically visible all colours of human eye, it is a kind of and equipment
It is unrelated, both do not depended on light or do not depended on the color system based on human eye physiological characteristic of pigment, also just because of this, Lab colour gamut
Color can not be shown device completely or pigment is presented.
It is RGB color domain in Fig. 1, shown in dotted line frame, RGB color domain is in industrial design with a kind of most wide color
Standard, by red (Red), green (Green), blue (Blue) three Color Channels variation and they are mutual folded
Calais obtains miscellaneous color, and RGB is the three primary colors (red, green, blue) for representing light；It is CMYK color shown in bold box
Domain, CMYK colour gamut are print color standards conventional in industrial production.In the industrial production, the image on a product needs elder generation
By the design in computer, printing then could be produced.
It is not light superposition but since pigment is to absorb light, therefore the color of image that practical paint prints
Domain is the colour gamut for being less than the image that electronic computer is fed back by display, and the CMYK colour gamut of print color standard is work in fact
The subset in industry design colours standard RGB color domain, range are less than RGB color domain.This image printed by conventional printing means
Not only have colour gamut difference with the image designed in computer, more with human eye naked eyes observable image there are apparent colour gamuts
Blank may refer to the white space between CMYK colour gamut and Lab colour gamut shown in FIG. 1.
To improve the color effects and vision matter that conventional printing means CMYK mode in the prior art prints the image to be formed
Amount, in order to improve the colour gamut for the color for printing target image.It is illustrated by taking inkjet printing as an example, as shown in Fig. 2, of the invention
In embodiment it is a kind of width colour gamut printing process one embodiment include:
S101, printing precoated shet；
Inkjet printing is that colour liquid ink is become fine particles through nozzle to spray in recording medium (such as paper),
The print resolution for generally depending on this inkjet printing of the picture quality printed, that is, DPI value.DPI(Dots Per
Inch, dots per inch) it is an important unit, it refers to that ink-jet printer in the range of per inch is printable
Ink dot number, in general, DPI value are higher, show that the printing precision of inkjet printing is higher, print resolution is also higher.
Another key factor for influencing picture quality is the absorption problem of recording medium, when ink is injected into paper
When upper, it should tightly be played symmetrically.If ink is absorbed by paper, and expands religion, then the area of ink dot will be than estimated
As a result to allow for target image greatly and seem fuzzyyer.
The present embodiment allows subsequent ink to be preferably sprayed in recording medium, is not in ink to overcome this point
It scatters at random astatically phenomenon, prints one layer of precoated shet, on the surface of the recording medium to improve spraying effect.
Different from traditional mode, traditional precoated shet is that precoated shet is coated in recording medium by roller, no
But the bad assurance of cumbersome and thickness, and full version can only be coated on the recording medium, waste is very big, and to dielectric printing
The flatness requirement in face is higher, there is also being adhered to each other when rollers roll with recording medium, has seriously affected subsequent
The printing of ink.
In this regard, the present embodiment using spraying method in the printout surface precoated shet of recording medium, be not present and recording medium
The problem of contact, therefore the flatness of the printing surface of recording medium is not required.And by the ink ejection amount of control nozzle, may be used also
