Abstract

The invention discloses a wallpaper printing process integrating intaglio printing and rotary screen printing. The process includes the following steps that firstly, a rotary screen printing plate and an intaglio plate are manufactured; secondly, paste is prepared and the viscosity of ink is adjusted; thirdly, paste is painted to the surface of a printed material through the rotary screen printing plate on rotary screen printing equipment, so that a required pattern is formed; fourthly, the printed material with the pattern is conveyed into a drying oven to be dried; fifthly, after being dried, the printed material with the pattern is conveyed into intaglio printing equipment, and the ink to be used is painted to the region, with the pattern, of the printed material through the intaglio plate; sixthly, the dyed printed material is conveyed into the drying oven to be dried; and seventhly, the dried printed material is rolled through a press roller, so that a product locally imprinted is obtained. By the adoption of the process, the specially-prepared paste is painted to non-woven paper backing paper through the pattern on the rotary screen printing plate to obtain the required pattern, dyeing is performed through the intaglio plate, the temperature of the printed material is increased in the drying oven, finally the product locally imprinted is obtained through rolling of the press roller, the printed pattern is fine and smooth, the workmanship is fine, colors are diverse, the pattern is rich, raw materials are guaranteed, and safety and environmental friendliness are achieved.

Description

A kind of wallpaper printing technique of justifying recessed one

Technical field

The invention belongs to wallpaper production field, specifically, relate to a kind of wallpaper printing technique of justifying recessed one.

Background technology

Intaglio printing is imprinted directly on stock by ink contained in intaglio plate pit, and the deep or light level in institute's print face is determined by the size of pit and the depth, if pit is comparatively dark, then the ink contained is more, and the layer of ink after impression, stock stayed is just thicker; If contrary pit is more shallow, then the quantity of ink contained is just less, and the layer of ink after impression, stock stayed is just thinner.

Cylinder printing, by inner cutter and automatically supplying ink system, is delivered to ink on stock in cylinder continuous high speed rotation process.

Intaglio printing and cylinder printing are the methods of two kinds of comparatively common at present printing wallpapers, and the wallpaper embossing that these two kinds of methods are produced is fine and smooth not exquisite, and more coarse, flower pattern is true to nature not, and third dimension is not strong.

Summary of the invention

For the problems referred to above, the invention provides that a kind of flower pattern is true to nature, the wallpaper printing technique of the fine and smooth exquisiteness of embossing, the recessed one of circle that third dimension is strong.

The technical solution used in the present invention is:

Justify a wallpaper printing technique for recessed one, it is characterized in that, comprise the following steps:

1) manufacture of cylinder galley and intaglio plate: according to wallpaper example edition design, uses laser-engraving technique to produce the cylinder galley and intaglio plate that complement one another;

2) slurry preparation and ink viscosity are allocated: prepare slurry, ink and water are mixed in a reservoir to stir evenly to obtain stand-by ink;

3) on cylinder printing equipment by step 2) slurry prepared is by step 1) the cylinder galley that makes is coated onto the surface of stock, the colored shape needed for formation;

4) by step 3) stock with colored shape that obtains sends in baking oven and dries;

5) stock having a colored shape after drying is admitted to gravure printing apparatus, by step 2) the stand-by ink allocated is by step 1) intaglio plate that manufactures paints and stock has the region of colored shape;

6) stock after colouring enters oven for drying;

7) step 6) in dry after stock through pressure roller pressure prick formed local embossed product, dry subsequently.

As preferably, described step 2) in slurry adopt at least one in starch, carboxymethyl cellulose, CMC, locust bean gum and sodium alginate to be prepared from.

As preferably, described step 2) in the viscosity of stand-by ink be wipe grace cup/No. 3 in 8 ~ 18 seconds, the volume of water is 1% ~ 15% of ink volume.

As preferably, described step 4), step 6) and step 7) bake out temperature be 40 ~ 130 DEG C.

As preferably, the surface engraving of described pressure roller has embossing.

As preferably, described stock adopts non-woven paper.

Compared with prior art, the invention has the beneficial effects as follows:

Special slurry is coated onto flower shape needed for formation on non-woven paper base stock by the colored shape in cylinder galley by the present invention, then through intaglio plate colouring, approach baking oven heats up, and eventually passes pressure roller and presses bundle to form local embossed product, have the following advantages:

1, embossing is fine and smooth, exquisite in workmanship

Local embossed wall paper passes through the design of printing, knurling mould different pattern, the chromatography of multiple printing color, the cooperation of various embossed channels, wallpaper embossing is made to present fine and smooth exquisite effect, flower pattern is true to nature, and third dimension is strong, is widely used in various high-grade household; The manufacture craft of local embossed wall paper requires the strictest in all wallpapers, not only needs to justify the support of recessed sleeve integrating gland printing apparatus accurately, even embossing roll shaft also wants pure hand engraving, technology difficulty has some idea of;

2, color is various, and pattern enriches

Local embossed wall paper color is various, pattern enriches, also is furnished with the shading of texture, its decorative effect is very good, the wallpaper collocation of different style can build the individual space of different sensation, and the steady generous European great Hua of existing applicable high-grade household, also has the geometric figure that the cheerful and light-hearted bold and unrestrained contrast of applicable young man is strong, as long as it is proper to design, local embossed wall paper can create arbitrary household atmosphere;

3, raw material guarantee, safety and environmental protection

Base stock adopts non-woven paper environment-friendly materials to do ground, Environmental-protection water-based ink printing, and the local embossed product color made is pure, euphorosia, sound-absorbing ventilative, elegant noble quality, texture are meticulous, flower shape is true to nature.
