Digital Printing Materials Light Box Cloth and Ink Usage

The prosperity of the advertising industry not only depends on the prosperity of market development, but also the aggressive progress of advertising companies of all sizes is a crucial factor. Nowadays, the demands of advertisers are getting higher and higher, and the new tricks of advertisement production are endless. The rapid development of China's advertising production industry is relatively early to accept this change, and the domestic advertising production industry has always been synchronized with foreign countries, from the initial development of neon signs to light box stickers and inkjet advertising.

The reason why German painting has won the attention and favor of the industry, summed up the reason is nothing but only three:

First, the operation control is simple and the production time is fast;
Second, installation and carrying are extremely convenient;
Third, the effect of the advertisement page is vivid, and it can create a super-normal effect.

These three major advantages are extremely suitable for the social rhythm of the information age that is changing at present. The main substrate for inkjet printing is light box cloth.

The light box cloth is composed of PVC material and mesh light guide fiber. It has good flexibility, uniform light transmission, easy to split, splicing, consignment, and simple outdoor installation. It is especially suitable for color inkjet printing. According to the requirements of outdoor use, the light box cloth can achieve waterproof, anti-mold, resistance to ethylene, cold and heat, anti-ultraviolet radiation and other effects. As the light box cloth has strong resistance to typhoon, it is particularly suitable for making large-scale outdoor advertising signs. At present, 95% of large-scale color inkjet light boxes in the Chinese market use light box cloth as the substrate.

The light box cloth is divided into three types according to the light transmittance and the position of the light source: a rear light box cloth, a front light box cloth and a grid cloth.

After the light box cloth is used to make the rear light source light box, the light transmittance is generally between 25% to 35%. Such light boxes are mostly medium and small, and are mostly used to make roadside light boxes, storefront light boxes and indoor promotional light boxes. The general area is small and does not exceed 100m2.

The front light box cloth is used to make the front light box, and its light transmittance is generally between 5% and 10%. This type of light box is more resistant to typhoon, so it is mostly used to make large-scale outdoor light boxes, such as building billboards, high-speed roadside light boxes, city Optimus light boxes. At present, large-sized outdoor light boxes in China between 100 and 400 m2 use such light cloths.

The grid cloth is designed according to Taiwan, Fujian and other typhoon climate regions. Because of the dense array of meshes on the surface of such materials, the wind can be transmitted through the surface of the light cloth, which can greatly reduce the pressure of the typhoon on the light box and make the screen even more vivid. Long-term outdoor use effect. Due to this feature, grid cloth is used to make super-large signage advertisements and construction advertisements.

High quality light box cloth

1. Strong color fastness: With a light cloth with poor color fastness, the screen will not only fade but also change color.

2. Good ink absorption performance: The ink-absorbing performance directly determines the color and saturation of the picture and the shelf life of the color.

3. Excellent splicing performance: Lamps with poor splicing properties are neither safe nor affect the overall effect of the picture.

4. Good surface self-cleaning: As the cloth absorbs a large amount of dust and miscellaneous dirt, the screen becomes dirty and affects the effect.

5. After anti-mildew treatment: the surface of the light cloth has begun to mold, not only affect the screen effect, but also affected the audience experience.

The light box cloth is divided into three types according to the production process: knife cloth light box cloth, calender light box cloth and legal light box cloth.

Knife scraping

The knife-scraper light box cloth technology is to apply the liquid PVC paste to the front and back sides of the base cloth with several back scrapers evenly, and then it is completely combined into a whole by the drying process, and then cooled to form. Its characteristics are strong permeability, tensile strength, and anti-peeling ability. Since the blade of the knife scraping method is a whole, the peeling phenomenon is eliminated, and the strength of the splicing section is greater than the product itself through welding. At present, the light box fabric width of this process can reach 5m. Due to the complexity of the production process and the relatively expensive production facilities, these products are mainly imported and have relatively high prices in the Chinese market. The most representative are ULTRALON from Germany, UNIFLEX from Korea and SIOEN from Belgium.

Calendering

Calendering method is to fully mix PVC powder and liquid plasticizer and other raw materials, and then it is bonded with the base fabric into a whole by the pressure of the high temperature heat roller. Its characteristic is that the surface is flat and the light transmission is even, and there is an advantage in the internal lighting light cloth. However, due to equipment restrictions, the width is generally not more than 3m. The 645 and 945 light box cloths developed by South Korea's 3M Company were produced using this technology; another Lexico light box cloth developed by South Korea’s LG Company is also representative of such processes.

Posted legally

Legally attached light box cloth is to form the upper and lower two layers of PVC film, through heating, under the pressure of the heat roller and the middle of the light guide fiber mesh together, cooling and molding. The greatest feature of this process is its excellent inkjet ink absorption and strong color expression. Therefore, with the rise of the large-scale inkjet industry, this type of light box cloth has brought endless life. At present, this type of light box cloth has a market share of more than 50% in China.

Due to different types of machine nozzle principle is different. Therefore, the ink used is also different. If the ink is selected incorrectly, the nozzle damage will be inevitable. The motherboard is the brain of the inkjet printer, and the ink is the blood of the inkjet printer. Therefore, the ink of the inkjet printer should be understood. Select the proper ink for your inkjet printer and you can get out of the ink. Misunderstanding.

Indoor dye-based thermal foam ink

Suitable for HP or ENCAD, NOVAJET indoor models, because the ink contains a high foaming agent, after the ink head resistance heating, let the ink in a very short period of time to produce air bubbles, and then squeeze the ink out but in a long time high Under the change of low temperature, the head of the ink chamber is lost in the severe environmental changes of high heat and high pressure. Due to the successful development of alternative inks, the cost is low, but the loss of the nozzle is an irreducible cost. General thermal foaming ink jet printers use inks that require between 70% and 90% moisture to keep the nozzles free from nozzles and heat. This means that sufficient time must be allowed for the ink to dry out on the media. Will spread out, so it installed more drying equipment on the machine, so as not to damage the screen.

Indoor dye-based micro piezoelectric ink

Applies to the use of EPSON nozzle models, mainly MIMAKIJV2 830/860/880 series and MUTOH RJ4000/6000, ROLAN FJ 40/50, including the latest MIMAKIJV-4, MUTOH RJ-8000 and ROLAND FJ-500/600 series, pressure The electric sprinkler uses a piezoelectric crystal to strike and oscillate a diaphragm that is fixed in the printhead so that the ink in the printhead is ejected. Because it is "cold spray", the nozzle does not need to be replaced regularly, but early ink prices are higher, so the early indoor production cost is higher than the thermal foam, the recently launched MUTOH RJ-8000 series uses the third generation nozzle and the MIMAKI JV4 series The fourth generation of EPSON nozzles, thus greatly improving the printing speed, and micro-piezoelectric ink is also reduced to 0.25 yuan / mL or less, so the indoor production will be micro-piezoelectric as the mainstream model.

Outdoor pigment micro piezoelectric ink

Suitable for use with EPSON nozzle models, mainly MIMAKI JV2 830/860/880 series and MUTOH RJ4000/6000, ROLAND FJ 40/50, including the latest MIMAKI JV-4, MUTOH RJ-8000 and ROLAND FJ-500/600 series However, due to the need to cover the film and make the outdoor process complex, the most deadly is that the cost has been far higher than the current domestic outdoor spray drawing price (about 30 yuan), but not become mainstream ink. However, there are still markets in foreign countries, because the foreign outdoor inkjet is still more than 300 yuan, because it is not suitable for China's national conditions, the country has gradually no company to adopt, and gradually withdraw from the Chinese market, so the ink can only become MIMAKI, MUTOH, ROLAND's "selling point" , but not much practical use.

Oily ink

Only applicable to MUTOH RJ-8000/RJ6000, ROLAND FJ50/40/500/400 and MIMAKI JV2 series. Due to the limitation of micro-piezo nozzles, outdoor weathering is about 4 months, since oil-based inks can be produced without lamination, and Spray coating light box cloth, so widely used in indoor production and outdoor replacement frequently (about six months) in the area.

Solvent ink (1)

The ink does not belong to the real solvent ink, and it can only be regarded as a ketone ink. Because it is corrosive to the PVC material, it can be used to ink normal light box cloth, and it is used on the IPON nozzles of MIMAKI and MUTOH. What is avoided is that the machine is also strongly corrosive, and the equipment will gradually become unstable, and often problems will only be discovered after the warranty period expires. In particular, the weather resistance can only last up to 3 months. "Fake", but because of the temptation of "can spray ordinary light box cloth", there are still many people fooled, the ink can only be said to be suitable for the production of "psychological" in China, and therefore can only be "short-lived", quickly eliminated from the market.

Solvent ink (2)

Applicable to large-scale spraying machine and the latest infiniti limit series, the ink has a strong corrosive, can be directly infiltrated into the light box cloth and PVC material inside, so the nozzle is more demanding, need to use a special solvent-type nozzle, and attached to the nozzle The equipment requirements are also high, so the solvent ink is not suitable for any nozzle of Japan EPSON, and only the British XRRA and SPECTRA companies have the ability to produce this nozzle at present. Sai Angel, SALSA, Wit 2360 and the latest limits are all equipped with such nozzles and equipped with an automatic ink filter system. Therefore, they are professional outdoor production equipment, and the outdoor weathering guarantee can reach about two years.
