The paper printing to be bestowed favor on newly with plastic film as medium

American researchers in a laboratory at the university of California, riverside, create no ink printing novel rewrite "paper", in the form of glass or plastic film as medium, based on the REDOX dye, have blue, red, and green three primary colors, recycled after 20 times, no significant loss in the contrast and resolution.Related research results published in the December 2, the online journal nature communications.

The paper first invented by Chinese, with a variety of purposes, the most common of which are used in writing and printing.In fact, the development of civilization and spread to a large extent thanks to the use of paper for writing materials.According to the survey, 90% of the nowadays business information is retained on the paper, although a large number of printing paper are discarded after used only once.As the use of the traditional paper, waste paper (and the cartridge) will be accompanied by a series of environmental problems, such as deforestation, forest chemical pollution of air, water and land, if the paper can be "wipe" many times, so this situation can be changed.

According to physicists organization network reported recently, the lab leader, of the university chemistry professor Yin Yadong said: "the dye 'paper' imaging layer formation, printing was realized by using ultraviolet light bleaching in the dye. Erasable 'paper' requires no additional printing ink, make it feasible in economy and environment. It represents a can meet the global growing demand for sustainable development and environmental protection and attractive alternative to conventional paper choice."

The novel "paper" is basically a glass or plastic film can be rewritten in the form of medium, letters and pattern can be repeated printing, keep for several days, and then through a simple heating erasure.It has three primary colors: blue, red, green, and by using the commercial REDOX dye methylene blue and neutral red and acid green preparation respectively, including dye in the titanium dioxide nanocrystal (these) as catalyst and hydrogen thickener cellulose (HEC).A mixture of dyes, catalysts and HEC to the "paper" added high reversibility and repeatability.

In the writing of "paper" phase, ultraviolet reducing dye to its colorless state.In erasing stage, REDOX dye to recover its original color, namely imaging materials through reaction with oxygen in the surrounding environment and restore its original color.Usually will be heated to 115 can accelerate the reaction, the erasing process is less than 10 minutes to complete.

Researchers said: "in this' paper printed words with high resolution, visible, under the condition of the external environment can keep more than three days, it has been long enough in practical applications, such as reading a newspaper. Even better, its simple production, low production cost, less toxicity and low energy consumption."

To reduce the total cost, the researchers are laboratory to recycle 100 times as the goal and strive to increase the use of the "paper".And study how to extend the printed text or image clarity more than three days, to expand its potential USES, and the possibility of multi-color printing.

China packaging carton is more suitable for using digital printing machine

Many European countries to reduce the number of printing color and specifications varieties to improve efficiency, reduce energy consumption and reduce the sewage discharge, environmental protection purposes, set up a lot of rules.But at the moment, China is not such a qualified standard, the carton specifications are a dime a dozen in the country.Market, carton order type is complex, but specific to the number of each variety is falling.Therefore, the development of China's carton industry got confused in many European countries do not exist.Therefore, in the field of digital printing in the packaging application has not formed in the international climate, and is more suitable for carton packaging market in China.

China is a large, anhydrous digital printing equipment once popularized in our country, will inevitably produce the butterfly effect, bring a subversive revolution of the global packaging industry.

Now when you meet the international order is the traditional practice of packaging industry need to both sides send plate samples with the reciprocating many times, take a long auxiliary time, but the future no water digital printing machine after intervention, the situation will completely change, foreign customers instantaneous can be done through the network to transmit the design draft to domestic manufacturers, factory put into production immediately, perhaps foreign clients through logistics can get the product in the second day.

The print didn't lock easy to cause the five problems

Press workers remove the print in a day is a few blocks, there were 10, less once when removing version didn't print lock, will have a great impact on the production quality of printing machine.Summarizes the longyin printing group, mainly has the following five aspects:

A, badly aligned

Print lock isn't the biggest effect is badly aligned, the factory is the printing without any problems, the next was badly aligned when printing.When this problem most of reason is that the print without locking.Because every time the lock version of the degree of different, so the location of the print is not the same.

Second, the ribbon for not neat

Ribbon for not neat is also among the common, due to print in the process of the lock version tight pine, then formed a ribbon for.So some operators found ribbon for not neat will hang the print from the new, or adjust the pad of paper printed edge direction.

Three, printing, virtual boundary

Because of loose print, ink print shift creates a loose, uneven ink transfer, leads to false edge.

Four, printing ink

Print is loose, the front-end transfer ink will be big, it is easy to form when printing ink accumulation causes because of the large amount of ink and printing ink.

Five, the fuzzy printing

Especially the fine print, the print due to loose, between the font is prone to heap ink, lead to fuzzy printing.
