Mean while, in order to prevent the cover burst side, covered front and back covers generally recommend Asian film or coating film, and some require a little high, and in the design of the production will be asked to cover a part of the text logo or bronzing, hot silver, hollow or partially UV, in order to enhance the effect. 2, leaflets, color pages, folding and other such commonly used when printing color pages coated paper or matte paper between 128G to 200G, 180G and above when doing art paper folding, will recommend Asian film coating to prevent burst edges. 3, posters, posters and other such are generally single-sided printing, matte paper or coated paper between 157G to 200G can, and some will need to post a few need to affix the tape on the back for easy business posted. 4, banners class flags are generally two-sided color printing, coated paper is generally between 200G to 300G or matte paper, film or coating often need to cover Asian film, in most cases are heterosexual requires die cutting. 5, the envelope type envelope with 250G or 300G generally coated or matte paper, film or coating the outside need to dumb film, due to the internal pocket, you need to die-cutting process, both sides have some sticky mouth, some are single side stick, insert more if relatively thick pockets need from the ridge. In addition, the inner envelope inserts for general use between 128G to 200G art paper or matte paper, slightly smaller than the size of the envelope, in order to facilitate insertion. 6, handbags classes have common printing paper bag between 200G to 300G coated paper, matte paper, white cardboard, etc., are needed laminating job. Horizontal and vertical open paper bag there is a difference in the choice of paper and equipment are required to clear handbag styles. Some bags are needed cheer the eye, and some A4 paper suppliers, A4 copy paper manufacturers

We are offering carbon a4 paper. (e) a4 paper variant of. A4 paper wet deformation and permanent deformation produced in the wet and dry conditions. Deformability a4 paper to print adversely. Generally, a4 paper and paper deformation rate of the fiber type and paper production related. Rag pulp paper grades deformation small, large chemical wood pulp paper create deformation unbleached chemical pulp is more easily deformed than bleached chemical pulp. Second, the aging of a4 paper archives in archives and use the process, archive a4 paper gradually undergoing irreversible change in appearance, structure and properties of the various aspects, known as "aging" or "worsening." a4 paper aging embodied in three aspects, namely, color, strength decreases and changes in chemical properties. 1. File a4 paper acidic hydrolysis of cellulose. A4 paper archives department at all levels of the majority of the existing archives containing acid. Acid is the most important factor causing archives a4 paper aging and even chalking. Because the archives acid catalyzed hydrolysis of cellulose degradation. Archives acids from: in the paper production process, such as mechanical papermaking cooking liquid, bleach, especially rosin sizing a4 paper brought to the acid; the acid gas in the air and dust in the acidic substance is archives adsorbed; writing, printing on the archival material a4 paper writing an acid; after the file mildew, mold will secrete organic acids such as oxalic acid and citric acid; cellulose, hemi-cellulose, especially wood su produce acidic substances in the oxidation or hydrolysis. 2. File a4 paper enzymatic degradation of cellulose. When records storage relative humidity, the archive is easy to mildew. Archives a4 paper yellow after mildew, stains little mechanical strength sharp decline, seriously damaged the ar

We offer Security A4 Paperof the light can be considered as time many small specular reflected light intensity is superimposed, when the brightness of the diffusing surface is a constant. known as the cosine diffuser 2. The internally reflected light, refracted light rays after entering the body, interng "> gloss and color collectively referred to as color. Since the color is more intuitive, and has for many mental and psychological state of the person, a more direct emotional impact, so people of color started earlier studies, this research work has been basically mature, and has been in daily life a wide range of applications. gloss same color, same human psychology can produce the appropriate response, especially plays an important role in print quality evaluation. 1. Surface reflected light, reflected light from the surface of the positive surface reflected light and diffuse surfaces composition of the incident light is reflected light: consistent with the law of reflection light intensity of the reflected light is referred to as being in addition to the reflected light and the reflectivity on the foreign material, and the object is mainly affected by the surface state of the light

128g to 200g art paper or matte paper, slightly smaller than the size of the envelope, in order to facilitate insertion. 6, handbags classes have common printing paper bag between 200g to 300g coated paper, matte paper, white cardboard, etc., are needed laminating job. Horizontal and vertical open paper bag there is a difference in the choice of paper and equipment are required to clear handbag styles. Some bags are needed cheer the eye, and some are direct wear a lanyard, mostly with cotton rope.A4 paper for printing a significant impact on the moisture content, water content is too low, brittle paper, printing is easy to produce static electricity; content is too high, would be difficult to dry the ink. Moisture change a great impact on the various properties of paper, with changes in moisture, which is quantitative, tensile strength, flexibility, folding and so will change, a4 paper size expansion will occur, or even curling, alice, wrinkling, lotus leaf and so on. A4 paper moisture tester can measure not only a4 paper, waste water, and can measure solids, liquids, food, chemical, dried fruit, grain, plastics, rubber, wood, soil, floor, medicine, textiles, can be detected, in addition to products containing volatile substances can not be detected, other products can be detected very versatile, is the first choice of customers. A4 and then converted to a digital display through the adc. Note 1, the body was kept in parallel with the measurement, the instrument shall be all three sensors gently press in a4 paper, cardboard measuring above. 2, a4 paper cartons.

loss of a few million, no one would easily assume this responsibility, a lot of disputes also resulting. Therefore, the two sides traded a4 paper at the time, must have considerable ability to judge, to judge from the appearance, the good feed this off. Especially those who are no printing presses, buy printing paper printing contract to other business units, as a result of the situation can not keep control of printing, but want to buy a4 paper, a careful visual inspection. Different a4 paper, its performance, there is a great difference between the use of the appearance of the different requirements. And a different machine, its papermaking conditions, the ratio of raw materials and there are also different, so check the appearance is based on a4 paper a4 paper actually see the two sides negotiated with the standard inspection, check out the non-compliant a4 paper, paper known to have the appearance of the disease a4 paper. The appearance of paper types disease: the appearance of the disease mainly paper a4 paper characteristic appearance of the surface shape and pattern differences to be named, but also to a4 paper papermaking defect common to be named. Paper disease more common are: air knife streak, calendering streak, streaks coating roll, cardboard warping, burrs, pits, spots, embossing, bankbook, scraper streaks like. Check the appearance of the paper's disease method: check the appearance of the paper's disease, except a very few require the use of instruments, in general, are based on sensory identification, inspection methods are mainly the following categories: Towards rays law: the cardboard look after facing the light source, with Have visually a4 paper surface defects; flat look test method: the a4 paper on a flat s inspection method:

We are offering tissue a4 paper. Lized hydrolysis of cellulose into the insoluble biocatalyst soluble sugars. Cellulase catalytic intense, it is possible within three months of the a4 paper cellulose destroyed 10% to 60%. Experiments show that after the archives a4 paper mildew firmness by 50% in five days, even if the long-term is not turning into a rotten brick. 3. Archives a4 paper photoaging. Archive long-term exposure to light, or through sun exposure, a4 paper will be different degrees of yellow hair brittle, or wet for newsprint archives for this change is particularly evident. This is a light prompted many chemicals to produce results on the photochemical reaction archives a4 paper. Potentially damaging light, the shorter wavelength of the light, the greater the radiation energy. Ultraviolet radiant energy which is great, it can cause serious damage. Archives a4 paper photoaging in the following three areas: (1) a4 paper dehydration, strength decreased. (2) acceleration profile a4 paper on various chemical reaction. (3) a4 paper cellulose pyrolysis. 4. Metal archives a4 paper the effects of aging. Water used in the paper production process, metal machinery, cooking liquid, packing facilities etc. Gave a4 paper left iron, copper, manganese, titanium, zinc, calcium, magnesium and other metal ions. Written, printed on archive a4 paper writing materials, falls on the archives of dust, dirt, metal file for binding and stored in a metal file cabinet, but also to a4 paper will bring a variety of metals. Although the content of the metal in the archives a4 paper's success, but on the aging process plays a4 paper archives should not be underestimated, mainly in: (1) the oxidation catalyst a4 paper cellulose degradation. Traces of iron, copper, cobalt and other.

Posed to the thickness of 50mm or more, so as to achieve best results.For years, futurists have been talking non-cash society, but for a variety of reasons, this idea had never become a reality. But now, with modern technology, the theory was just electric cars and clean energy can become a reality, no cash society is no longer on paper, into reality sooner or later.with modern technology, the theory was just electric cars and clean energy can become a reality, no cash society is no longer on paper, into reality sooner or later. Oand is one of the tasks file protection technology. First, the file a4 paper performance (a) a4 paper's mechanical strength. The ability a4 paper a4 paper after exposure to light overall reflected light level is a4 paper. In most cases, a4 paper caused by the action of light and heat of white decreased, and the strength is reduced, often referred to as "yellowing." yellowing is one of the characteristics of aging a4 paper. (e) a4 paper suppliers, a4 copy paper manufacturers and torque is then analyzed and dragged voltmeter tension in the mold at some radius. Section 6.2 gives a similar name.
