Description
Technical field
The invention belongs to printing technology, color before the printing more particularly to a kind of fluoroleum for being related to fluorescent ink ink
Color analogy method.
Background technique
Fluorescent ink, which prints, with the naked eye to distinguish between colors, and need to develop the color in the case where UV lamp is irradiated, so
It can not all know that designed pattern finally prints off the appearance come before Plate making printing, traditional method is all that Plate making printing comes out, out
Come what effect is exactly what effect, then needs to make a plate again if necessary to adjustment, can just obtain desired effect repeatedly.
As it can be seen that existing method once to make a plate it is difficult to ensure that printing obtains ideal effect, if plate-making will lead to material again again
The waste of material and delaying for duration.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind can obtain fluorescent ink printing before Plate making printing
Color simulation method before the fluoroleum of effect inks, to overcome the shortcomings of the prior art.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of preceding color simulation method of fluoroleum ink, which comprises the steps of:
S1, it is fabricated to and is enough the original electron colour gamut table being made of color lump comprising common gamut range；
S2, selection fluorescent ink, printing machine and printing condition, using the fluorescent ink and the printing machine described
The original electron colour gamut table is printed on film under printing condition, obtains printing colour gamut table；
S3, it is irradiated in confined space with UV light source and prints colour gamut table, so that printing the color of each color lump on colour gamut table
It displays, obtains illumination colour gamut table；
S4, each color lump color that the illumination colour gamut table is recorded with the mode taken pictures simultaneously are converted into rgb format, obtain
Central electron colour gamut table；
S5, selection printer, pad-ink, by the central electron colour gamut table printer and the pad-ink
It is come out in print on paper, obtains printing colour gamut table；
S6, compared one by one with each color lump color of printing colour gamut table with each color lump in the illumination colour gamut table
Compared with according to comparing, being adjusted to the color value of each color lump in central electron colour gamut table, then by central electron adjusted
Colour gamut table is come out with the printer and the pad-ink in print on paper again；
S7, step S6 is repeated, until with the printer and the pad-ink in the printing come out in print on paper
The color of each color lump of colour gamut table and the solid colour of each color lump in illumination colour gamut table；
S8, the printing colour gamut table of last time is scanned to the CMYK value and Lab value for obtaining each color lump with scanner,
It forms the color print command of corresponding each color lump of original electron colour gamut table and assigns the printer；
Before S9, Plate making printing, by the design original text printer and the pad-ink according to the color print command
Printed, print the effect seen of naked eyes be exactly with the fluorescent ink and the printing machine under the printing condition
The effect printed in the future.
In a preferred embodiment of the invention, in confined space, the printing colour gamut table liner is on blackboard.
In a preferred embodiment of the invention, the original electron colour gamut table includes the color lump of 1331 folded colors.So
More color lumps be enough to cover naked eyes it can be seen that gamut range.
By adopting the above technical scheme, the present invention realizes can obtain fluorescent ink printing effect before Plate making printing
Fruit avoids the waste of material and delaying for duration.
Detailed description of the invention
Fig. 1 is the original electron colour gamut table comprising 1331 folded color color lumps；
Fig. 2 is first time central electron colour gamut table；
Fig. 3 is second of central electron colour gamut table；
Fig. 4 is that the printing colour gamut table of last time is scanned the CMYK value and Lab value for obtaining each color lump with scanner
Screenshotss (length is limited, only provides first 32).
Specific embodiment
By taking Tian Shuan Year TS/Y line fluorescent ink as an example, the printing effect of the fluorescent ink is simulated, using following steps:
Step 1: being fabricated to and be enough the original electron colour gamut table being made of color lump comprising common gamut range.The present embodiment
In, make 1331 folded color color lumps altogether, so multiple color lumps be enough to cover naked eyes it can be seen that gamut range, such as Fig. 1 institute
Show.
Step 2: selection Tian Shuan Year TS/Y line fluorescent ink selects Jiangyin Correspondent F-1000 printing machine, printing condition: printing
120 ms/min of speed, 50 DEG C of oven temperature.
Original electron colour gamut table is printed out on film under the printing condition using the fluorescent ink and the printing machine
Come, obtains printing colour gamut table.
Step 3: by printing colour gamut table liner on blackboard, with UV light source irradiation printing colour gamut table in confined space, making
The Color development that each color lump on colour gamut table must be printed comes out, and obtains illumination colour gamut table.
Step 4: recording each color lump color of illumination colour gamut table with the mode taken pictures and be converted into rgb format, obtain
First time central electron colour gamut table, as shown in Figure 2.
Step 5: selection Epson7910 printer, the original-pack pad-ink of EpsonEco, by this dozen of central electron colour gamut table use
Print machine and the pad-ink come out in print on paper, obtain printing colour gamut table.
Step 6: with the printing each color lump color of colour gamut table compared with each color lump carries out one by one in illumination colour gamut table, according to
Compare, the color value of each color lump in first time central electron colour gamut table is adjusted, such as by the rgb value of A color lump in Fig. 2
(10,147,255) are adjusted to (11,148,255), and the rgb value (230,14,141) of B color lump is adjusted to (228,13,139), C color
The rgb value (80,100,112) of block is adjusted to (80,100,110), obtains second of central electron colour gamut table, as shown in Figure 3；So
Second of central electron colour gamut table adjusted is being printed with the printer and the pad-ink again afterwards；
Step 7 repeats step 6, until the printing colour gamut come out with the printer and the pad-ink in print on paper
The color of each color lump of table and the solid colour of each color lump in illumination colour gamut table；
The printing colour gamut table of last time is scanned the CMYK value and Lab for obtaining each color lump by step 8 with scanner
Value, as shown in figure 4, forming the color print command of corresponding each color lump of original electron colour gamut table and assigning the printer；
Before step 9, Plate making printing, by design original text printer and the pad-ink according to the color print command in paper
It is printed on, printing the effect that naked eyes are seen is exactly to use the fluorescent ink and the printing machine will under the printing condition
Come the effect printed.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Invention, and be not used as limitation of the invention, as long as in spirit of the invention, to embodiment described above
Variation, modification will all fall in scope of protection of the claims of the invention.
