In today's digital age, advertising and visual display methods are changing with each passing day. As an efficient, flexible and widely used advertising medium, DPI digital printed flexible banners are gradually occupying an important position in the market. This article will deeply explore the definition, principle, classification, characteristics, application field, production process, market status and future development trend of DPI digital printed flexible banners.
DPI (Dots Per Inch) is an important indicator for measuring image resolution. DPI digital printed flexible banners refer to banners used for advertising, event display, etc. that are made by printing images or texts on flexible materials with a high precision of dots per inch using digital printing technology. This type of banner can present a high-definition and colorful printing effect to meet the visual needs of different scenarios.
The printing principle of DPI digital printing flexible banner is based on the conversion and output of digital image information. In digital printing equipment, the computer digitizes the designed image or text information and decomposes it into countless tiny pixels. The information of these pixels is transmitted to the printing nozzle. According to the instructions, the nozzle uses piezoelectric or thermal foaming inkjet technology to accurately spray different colors of ink onto the surface of the flexible banner material. Each ink dot corresponds to a pixel in the image. Through the close arrangement and combination of a large number of ink dots, a high-resolution image is finally restored on the flexible material to achieve high-quality printing effects. Taking thermal foaming inkjet technology as an example, the heating element in the nozzle instantly heats the ink, causing it to form bubbles and expand rapidly, squeezing the ink out of the nozzle hole and spraying it onto the substrate; piezoelectric inkjet technology uses the deformation of piezoelectric materials under the action of an electric field to squeeze the ink out of the nozzle hole.
l PVC flexible banner material : Polyvinyl chloride (PVC) material has good flexibility, waterproofness and durability. It has a smooth surface and can absorb ink well, and the printed images are bright and highly saturated. It is often used for advertising banners that are displayed outdoors for a long time, such as large shopping mall exterior wall advertisements, outdoor promotion banners, etc.
l Fabric-based flexible banner materials : including non-woven fabrics, polyester fabrics, etc. Fabric materials are soft, comfortable to the touch, and have good breathability. The printing effect presents a soft texture and is often used for banner displays in indoor exhibitions, cultural activities, and other scenes, giving people a warm and comfortable visual experience. For example, in art exhibition venues, using non-woven banners for publicity can complement the exhibition atmosphere.
l Translucent flexible banner materials : These materials, such as special vinyl materials, have a certain degree of translucency. When used for backlit signs and displays, light can pass through the fabric, making the printed image still clearly visible at night or in low light conditions, and presenting a unique luminous effect. They are often used in urban night scene lighting advertisements, light box banner advertisements in subway stations, etc.
l Direct inkjet printing of flexible banners : Directly spraying ink onto the surface of flexible materials is the most common digital printing method. It can directly achieve high-precision image printing and is suitable for printing needs of various complex patterns and texts. For some personalized and uniquely designed banners, direct inkjet printing can accurately restore the design intent.
l Thermal transfer digital printing flexible banner : first print the image on the transfer paper, then transfer the ink on the transfer paper to the flexible banner material through high temperature and high pressure. This method allows the ink to penetrate better into the material, improves the wear resistance and color fastness of the printed image, and is often used in banner production with high requirements for printing quality and durability, such as long-term brand promotion banners.
DPI digital printing can achieve higher resolution, usually up to 300DPI or even higher, so that the printed images and text are rich in details and have clear edges. Compared with traditional printing methods, more detailed information can be presented on the same size banner, which improves the visual effect and appeal. For example, in a banner promoting a high-end electronic product, high-resolution printing can clearly show the exquisite appearance and delicate texture of the product.
Through advanced color management system and high-precision inkjet technology, DPI digital printing flexible banners can present extremely bright and rich colors. It can accurately restore various colors in the design draft, and the color saturation and contrast can reach a high level, making the banner more visually eye-catching and easier to attract the audience's attention. In banners for music festivals, fashion events and other scenes, rich and bright colors can better create a warm and fashionable atmosphere.
Made of flexible materials, the banner is soft and easy to fold and carry. It is more convenient and quicker during transportation and installation. Compared with traditional hard billboards, flexible banners can easily adapt to the display needs of various shapes and spaces, and have higher flexibility. For example, in some temporary event venues, staff can quickly unfold and install flexible banners, saving time and labor costs.
Digital printing technology makes personalized customization extremely easy. The printed content, size, color, etc. can be quickly adjusted according to the specific needs of customers. Whether it is small-scale customization or large-scale customization, it can be completed efficiently. For corporate promotional activities, elements such as corporate logos, specific product information and event themes can be accurately printed on banners to achieve precise brand promotion.
Compared with traditional printing methods, DPI digital printing flexible banners usually use water-based ink or environmentally friendly ink in the production process, which reduces the volatilization and emission of organic solvents and has less pollution to the environment. At the same time, the flexible material itself is also recyclable, which meets the environmental protection requirements of today's society.
l Commercial advertising : DPI digitally printed flexible banners are often used by major shopping malls, supermarkets, and stores for promotional activities and new product launches. Their eye-catching visual effects can attract the attention of passers-by and effectively convey promotional information and product features. For example, during the anniversary celebration of a shopping mall, a large flexible banner hung at the entrance of the mall displays the discounts and exciting content of the event with bright colors and prominent text.
l Outdoor advertising : Flexible banners are widely used as an economical and effective form of advertising in outdoor places such as city streets, highways, and building exteriors. Due to their good durability and waterproofness, they can be displayed in outdoor environments for a long time and continuously spread advertising information. For example, brand promotion banners on the side of highways can quickly attract the attention of drivers and passengers while vehicles are driving.
l Exhibitions : At various exhibitions and events, flexible banners are used to display the brand image, product information and booth guides of participating companies. Its lightness and easy installation allow exhibitors to quickly build a display environment and highlight the characteristics and advantages of the company through high-resolution printed images. For example, in technology exhibitions, companies use flexible banners to display the latest scientific research results and innovative products.
l Cultural and sports events : When holding music festivals, concerts, sports events and other events, flexible banners can create a warm atmosphere. You can print the theme of the event, celebrity images, athlete style and other content to enhance the audience's sense of participation and the attractiveness of the event. For example, at a football match, fans hold flexible banners printed with the logo and slogans of their supporting team to cheer for the team.
l Public welfare publicity : Government departments and public welfare organizations use flexible banners to spread public welfare concepts when conducting public welfare publicity activities such as environmental protection, health, and safety. High-definition printing can make the publicity content clearer and easier to understand, and widely convey it to the public. For example, in the public welfare activities advocating garbage classification, the flexible banners hung in the community use vivid patterns and concise text to publicize the importance and methods of garbage classification to residents.
l Traffic guidance : In some transportation hubs, construction sites and other places, flexible banners are used to publish traffic guidance information, safety warnings and other content. Its eye-catching color and large size can make pedestrians and vehicles pay attention to relevant information in time, ensuring traffic order and construction safety. For example, on road construction sections, flexible banners with the words "Construction ahead, please pay attention to safety" are set up to remind drivers to drive carefully.
First, the designer uses professional graphic design software (such as Adobe Photoshop, Illustrator, etc.) to design and create banners according to customer needs and usage scenarios. During the design process, factors such as image resolution, color mode, and text layout are fully considered to ensure that the design draft can meet the requirements of DPI digital printing and achieve good visual effects. For example, in order to ensure the clarity of the image after printing, the resolution will be set at more than 300DPI during design, and the color mode will be selected as CMYK mode to ensure accurate color reproduction.
For some digital printing processes that require plate making (such as thermal transfer digital printing), after the design draft is completed, the image information needs to be made into a printing plate. Laser plate making technology is usually used to engrave patterns and text information corresponding to the image on the plate through a laser beam. The accuracy and quality of plate making directly affect the effect of subsequent printing, so it is necessary to strictly control various parameters in the plate making process to ensure that the pattern on the plate is clear and accurate.
The prepared flexible banner material is installed on the digital printing equipment. The equipment accurately sprays ink onto the surface of the material through the nozzle according to the digital information of the design. During the printing process, it is necessary to control the parameters such as printing speed, nozzle temperature, ink supply, etc. to ensure the stability and consistency of printing quality. For example, by adjusting the nozzle temperature, the viscosity and spraying effect of the ink can be controlled to avoid the situation where the ink blocks the nozzle or sprays unevenly.
l Cutting : After printing, use a cutter or cutting machine to accurately cut the banner according to the design size requirements, remove the excess edge parts, and make the banner size meet the standard.
l Sewing and reinforcement : For some larger banners, the edges are sewn and reinforcement strips or grommets are added to enhance durability and installation convenience. For example, nylon straps are sewn on the four corners and edges of the banner or metal grommets are installed to facilitate the use of ropes or hooks to fix it when hanging.
l Lamination (optional) : If you need to further improve the waterproof, sun-proof and wear-resistant performance of the banner, you can laminate the printed banner. The laminating machine covers the surface of the banner with a layer of transparent protective film to protect the printed image from the influence of external environmental factors and extend the service life of the banner.
