Abstract
The invention discloses environment-friendly aqueous pigment ink. The ink is prepared from the following components by mass: 15-30% of pigment, 0.1-7.5% of surfactant, 0.02-0.09% of PH regulator, 2.5-7.5% of acrylic resin and 12.5-27.5% of organic solvents. The invention also discloses a novel digital direct printing method adopting the ink. The pigment ink can be directly printed on the surfaces of solvent-based materials by the method. Compared with the traditional printing methods, the method disclosed by the invention has simple process, is environment-friendly, has low equipment investment and meets the requirement for low cost.
Description
Technical field
The present invention relates to stamping machine and use the ink material technical field; Relate in particular to and directly to print on printing material, like the technical field of the solvent-based inks on the printed apcksging materials such as Label label, grey paperboard, ivory board, powder paperboard, stone paper, art paper, hole paper.
Background technology
Common aqueous pigment ink is applicable to cated medium at present, is coated with type and swelling type medium like castings such as ink-jet Inkiet Paper, RC-Glossy Photo Paper, Back Film, high light Alhue paper, light face photo paper, gloss printer papers.The characteristics of these media are that the surface scribbles the very strong coating of one deck absorbency, and coating and ink well matched can absorb large quantity of moisture and fast doing in the ink.
And common aqueous pigment ink directly is printed on uncoated printing material (like Label label, grey paperboard, ivory board, powder paperboard, stone paper, art paper, hole paper etc.) last time; Because the printing material surface does not have the such coating in ink-jet printing paper surface, problems such as heap China ink, imbibition, loose colour, be full of cracks, color be not gorgeous then can appear.Generally, the pioneer can improve the performance of ink through revising ink set, and using more, the high-grade starting material improve above-mentioned bad phenomenon.But these methods have all improved production cost greatly.
Traditional printing complex process in addition, traditional printing mode need color separation, the film, printing down, go up several operation of machine printing, and because of model change fast.The Label label that needs, packing box etc. are more and more littler in batches, and kind is more and more, as adopting the mode of printing, and complex procedures then, cost promotes.Common aqueous pigment ink is printed on PVC, the body sticker equal solvent type material heap China ink can occur, melt, not anti-wiping, non-watertight, on oil medium, can not use.
Publication number is CN102161848A; Open day is on August 24th, 2011; Denomination of invention is through computer-controlled spray ink Printing brush version machine the thermal contraction ink to be sprayed on to form image on edition primary surface for the Chinese invention patent application of " direct plate making of ink-jet printing is with the thermal contraction ink " discloses a kind of thermal contraction ink, will heat the version base then; Make the mixture solidified of thermosetting resin and thermal contraction material, improve the pressrun of forme image section.The thermal contraction material can make forme resolving power improve, and forme has good printability when last machine prints.
Summary of the invention
The objective of the invention is to these a series of problems, develop and a kind ofly can directly be printed on the paint ink on the printing material, not only can reduce cost, and than traditional images printing environment-friendly.
Another object of the present invention is to develop a kind of novel digital method of direct printing, common aqueous pigment ink directly is printed on the printing material, imaging effect reaches the printed matter standard.
In order to reach the foregoing invention purpose; The present invention has adopted following technical scheme: a kind of environment-friendly water-based paint ink comprises the component of following mass content: colorant 15～30%, tensio-active agent 0.1～7.5%, PH regulator 0.02～0.09%, vinyl resin 2.5～7.5% and organic solvent 12.5～27.5% in its prescription.
Preferably, also comprise sterilant 0.05～0.2% in the said prescription.
Specifically, said vinyl resin is a water-borne acrylic resin, and it contains following molecular structure
Wherein, R represents H or CH
3, R ' represents H, alkyl, alkoxyl group, alkane thiazolinyl or aryl.
Wherein, said PH regulator is triethylamine or sodium hydroxide.
Said tensio-active agent is the sim alkylphenol Soxylat A 25-7.
A kind of novel digital method of direct printing is characterized in that may further comprise the steps:
1) prepares aforesaid paint ink;
2) ink-jet printer is transformed, heating unit is set, to accelerate to print to material at its print area
But on paint ink rapid drying;
3) said paint ink is printed directly to the solvent-borne type material surface.
As preferred version, said Method of printing also comprises uses the step that color management software is regulated and control, and through it is carried out the linearizing color management, makes between paint ink and the printing material matched performance good.And utilize its output effect of software regulation and control.
Specifically, said print area comprises to be printed the paper feed forefoot area, prints word garage and walk the zone and print back paper advance mechanism and printing material contact area, its objective is that the quickening paint ink is printing to rapid drying on the printing material.
Specifically, said heating unit comprises that auxilliary heating unit of electricity or infrared heating device or increase low-grade fever wind vertically heat.
The present invention develops and a kind ofly can directly be printed on the paint ink on the printing material; Develop simultaneously and a kind ofly can directly above-mentioned paint ink be printed on the method on the printing material; Utilize the present invention can adopt the digital mode of printing pattern directly to be printed on the printed apcksging materials such as Label label, grey paperboard, ivory board, powder paperboard, stone paper, art paper, hole paper or on the solvent-based inks material therefor (materials such as PVC, body sticker, PET); The ink-jet paint ink is applied to brand-new field; Ink printing is become environment-friendly type print, remedied the deficiency in the traditional printing, replaced solvent-based inks; With solvent-based inks relatively, have odorlessness, beautiful in colour, the advantage of environmental protection more.On piezoelectricity or the pairing stamping machine of heat foamable printhead, directly print printed apcksging material, remedied the deficiency of packing picture and text printings such as traditional printing Label label with the ink-jet paint ink.Compare with traditional printing, present method technology is simple, has reduced color separation, the film, printing down, has gone up several operation of machine printing; Do not need color separation, the film, printing down, plate-making; Design and can print, the sample manuscript content can be adjusted at any time, proofreaded, and satisfies the packing demand that market is little, many, become.And equipment drops into little, satisfies low-cost requirement, the environmental protection more of this method.

Lab≤3NBS; Require Δ E for neutral ash, memory colour
LabPreferably less than or near 2NBS (Δ Ecmc≤1), the average color difference Δ E of all color lumps
Lab≤3.5 (Δ Ecmc≤2).
(4) above-mentioned paint ink is printed directly to the solvent-borne type material surface.
Use without EPSON Stylus Pro 7800 stamping machines of transforming with do not carry out color management with stamping machine that transformed and after passing through color management the printout figure carry out the actual effect analysis:
1. on printing material, represent effect:
When wherein be full of cracks is tested, with 40 times of reading lens visual observations.
2. colour gamut contrast:
Shown in Fig. 1～3, be gamut map according to usual way and the present invention's output, wherein: black line is a this patent method ink, and white line is the usual way ink.Can see that from Fig. 1～3 this patent method is bigger than usual way colour gamut, color is more gorgeous, and color reducibility is far above the usual way ink.
3. aberration contrast:
| Aberration | Common Method of printing | This patent method |
| Average?delta?E | 1.13 | 0.77 |
| Average?delta?E?94 | 0.91 | 0.54 |
| Average?delta?E?CMC | 0.75 | 0.39 |
