Description
Technical field
The present invention relates to printing technology more particularly to a kind of grey black four-colors offset printing ink based on H-UV printing.
Background technique
Conventional lithographic offset printing uses oil-based ink, and when being printed using this kind of ink, printed sheet needs to stand 12-24 at room temperature
A hour just can be carried out subsequent processing after the ink on printed sheet is completely dried, significantly reduce production efficiency.Printing simultaneously
Will appear ink dries after being completely dried and move back phenomenon, that is, be completely dried rear ink density can than it is unseasoned when ink density it is low,
Printing color is set deviation occur, it is difficult to control product quality.
On the basis of this printing technology, UV (ultraviolet light, Ultra-Violet Ray) printing technology, UV printing are proposed
Technique is a kind of a kind of printing technology dry, cured printing ink by ultraviolet light, needs to consolidate the ink containing photosensitizer with UV
Change lamp to match, makes that chemical change occurs inside UV ink or UV gloss oil, to make printing ink layer solidify, to reach drying
Effect.It is printed using this kind of drying process, the ink on printed sheet can sufficiently be solidified before reaching pile, be dried.
Subsequent processing can be entered after being completed for printing, eliminate the time for waiting printing to be completely dried.
H-UV (High sensitivity-Ultra Violet, high sensitivity ultraviolet light drying system) is that Japan is small gloomy
(Komori) company researches and develops, and component part includes ultraviolet (UV) lamp and high sensitivity ultraviolet UV printing ink.H-UV is filled in collection
One UV lamp of installation is set, can both ensure transcendent press quality and reliability, while sending out in terms of reducing cost and environmental protection
Positive effect has been waved, printing rapid draing can be made, has saved the time.
At present without the four color ink special of grey black for being suitable for H-UV technique.Since drying mode changes, match in ink
Fang Chengfen and proportion need to make corresponding adjustment.But due to the particularity of drying mode, ink is caused to be printed on after paper
There is no the time of levelling.Therefore the printed matter color produced using H-UV technique is dimer, and level contrast is poor, granular sensation
By force, image is not fine and smooth enough, and the color effects and tradition offset printing ratio of conventional four-color process black and white do not protrude.Although UV drying process
Improve production efficiency well, but product quality is glided, and cannot be considered in terms of quality and efficiency, it is impossible to meet client for
The demand of high-quality printing.
Summary of the invention
To solve the above problems, so that being realized when using four color offset lithographic H-UV techniques printing black white image product
The high quality printing effect of pure black and white proposes the grey black four-colors offset printing ink of the invention based on H-UV printing.
To achieve the goals above, this invention takes following technical solutions.
The present invention provides a kind of grey black four-colors offset printing ink based on H-UV printing, comprising: blue-black color ink CK, red and black

NO is that U.S. chemical abstract service society (Chemical Abstracts Service, CAS) is the registration number that chemical substance is worked out,
This number is the important tool for the chemical substance information that retrieval has multiple titles, is certain substance (compound, high molecular material, life
Unique digital identification number of object sequence (Biological sequences), mixture or alloy.
The tissue CAS that divides into of American Chemical Society is responsible for dispensed materials one No. CAS of each appearance in the literature,
Purpose is the trouble in order to avoid chemical substance there are many title, keeps the retrieval of database more convenient.Nowadays almost all of
Chemline all allows with No. CAS retrieval.It has been registered for by 11:31:00 on October 5 2010 America eastern time, CAS
62,164,509 kinds of substance latest datas, and also increased with daily more than 4000 speed.
No. CAS format: one No. CAS is divided into three parts with hyphen "-", and there are 2 to 7 bit digitals in first part, and second
There are 2 bit digitals in part, and Part III has 1 bit digital as check code.No. CAS in ascending order and without any inherent meaning.
The calculation method of check code is as follows: last position of CAS serial number (the first and second part number) multiplied by 1, the second last position multiplied by
2, and so on, then again all product additions, then with divided by 10, remainder is exactly the check code of Part III.It lifts
For example, water (H2O two parts are 7732-18 before No. CAS), then its check code is (8 × 1+1 × 2+2 × 3+3 × 4+7 × 5+
7 × 6) mod 10=105 mod 10=5.(mod is complementation operator)
