UV flatbed printer makes KT board（ Foamboard） processing easier

KT board is a kind of plate-like material made of polystyrene. The PS material particles are foamed into a board core and pressed by surface coating. KT board is light, not easy to deteriorate，and convenient for subsequent cutting and processing. It is widely used in advertising display, architectural decoration, cultural publicity walls，and packaging. The traditional KT board adopts film coating and board coating process, which has high labor and time cost. The difference is that UV flatbed printer brings different production methods to KT board processing.

At the earliest stage, KT board was divided into hot board and cold board. Now it is generally divided into PS film surface KT board, paper surface KT board, and PVC film surface cold-pressed KT board. KT board is widely used in indoor and outdoor publicity. Besides exhibitions, it is also applied in the construction and home decoration industry, such as KT board decorative painting. UV flatbed printer is a fantastic tool for printing decorative pictures, which is also suitable for KT board printing.

UV flatbed printers can print patterns directly on KT board. They save many traditional processes and significantly shorten the production time. They are especially suitable for small orders requiring changeable pictures and texts and can quickly respond to customer needs. In addition, the UV printer with a Ricoh nozzle and white color varnish scheme can also achieve oil painting like a three-dimensional relief effect.

For KT board printing, besides photo mounting and direct printing by UV flatbed printer, there are also devices with dual characteristics of UV curing and photo, such as “Mr. board”, which can also reach a printing speed of more than 40 square meters per hour. Of course, the needs of customers are always different. For advertising processing users requiring higher printing speed and printing needs of multiple materials and shapes, UV printers may have more advantages in versatility and capacity improvement.

The UV printing solution of KT board is to print patterns directly on KT board through UV flatbed printer. Through UV flatbed printer, processors can complete both large orders and small orders quickly. For users with small batch orders, delivery on the same day can be realized.

KT board UV flatbed printer adopts G5 nozzle, which can print 3D relief effect through the color configuration of color + white + varnish.

As one of the primary materials of the current media, KT board is suitable for medium and short-term advertising production with high-quality requirements and will not be deformed when used as poster board, writing board, promotion display board, etc. The solution of KT board UV printer not only brings different production modes for KT board advertising production but also gives advertising manufacturers a  new choice.

How to improve the adhesion of UV ink and effective methods？

When using a UV flat-panel printer to print some materials, the problem of low adhesion of UV ink to a substrate is sometimes caused by the instantaneous drying of UV ink. This article is to study how to improve the adhesion of UV ink to substrate.

Corona treatment

It has been found that corona treatment is an effective method to improve the adhesion of UV ink! The positive and negative electrodes of the corona device are respectively connected to the ground and the induced air nozzle. The high voltage and high cycle wave is used to make the electric shock molecules eject from the induced air nozzle and accelerate to the positive electrode with high-energy free electrons. In this way, the polarity of the non-absorbent material can be changed. It increases surface roughness and strengthens the combination ability with the ink, finally reaches the purpose of achieving the proper UV ink adhesion and improving the adhesion fastness of the ink layer.

The surface tension stability of corona-treated materials is poor, and the corona effect will gradually weaken as time goes on. Especially in an environment with high humidity, the corona effect will reduce faster. If a corona-treated substrate is used, it must cooperate with the supplier to ensure the freshness of the substrate. Common corona treatment materials include PE, PP, nylon, PVC, pet, etc.

UV ink adhesion promoters

In many cases, cleaning the substrate with alcohol will improve the adhesion of UV ink on the substrate. If the adhesion of the substrate to UV ink is inferior or the product has high requirements for UV ink adhesion, the primer / UV ink adhesion promoter to promote UV ink adhesion can be considered.

After the primer is applied to the non-absorbent substrate, the adhesion of UV ink improves and achieves the ideal adhesion effect. Unlike corona treatment, chemical primer materials do not contain non-polar oil molecules, which can effectively eliminate the instability of the corona effect caused by the migration of such molecules. However, the application scope of primer is selective, and the result is better for substrates such as glass, ceramics, metal, acrylic, and pet.

UV ink curing degree

Generally speaking, when the UV ink is not fully cured, we can observe the poor adhesion of UV ink on the non-absorbent substrate. To improve the curing degree of UV ink, we can start from the following aspects:

1) Increase the power of UV curing lamps.

2) Reduce printing speed

3) Extend the curing time.

4) Check whether the UV lamp and its accessories work regularly.

5) Reduce the ink layer thickness.

Other methods

Heating: in the screen printing industry, it is recommended to heat the substrate before UV curing when printing on the substrate that is difficult to adhere. After heating with near-infrared light or far-infrared light for 15-90 seconds, it can strengthen the adhesion of UV ink on the substrate.

Varnish: if the UV ink still has adhesion problems on the substrate after adopting the above suggestions, a layer of protective varnish can be coated on the surface of the print.

Cutting: if there is only an adhesion problem during cutting, it is recommended to cut the substrate to the required size before printing. The cutting edge of the cutting tool must be sharp. A rotary cutter will cut better than ordinary straight blade scissors.

Foam board and Its Applications in Nowaday Industry

Foam board is one of the most popular and versatile materials in today’s advertising industry. This material provides affordable and high-quality solutions for individuals and businesses in all sectors. It features a short application life of around 6-12 months, recyclable properties, and highly competitive costs. Foam Board is considered as an ideal material for temporary projects with tight budgets that don’t want to sacrifice quality. Foam Board has a variety of applications, including:

  • Informative Displays
  • Trade Show Advertising
  • Promotional Events
  • POP Signage
  • Display Systems

At Skyline Composites, We produce dozens of foam board product models that supply a wide range of creative and live events, trade shows, photo, stage applications. We always recommend foam board printing and photo mounting to our customers when guaranteeing them optimum results. Here, we would like to introduce some of the main projects which are the most suitable solutions to the foam board printing applications.

UV Flatbed Printing for Business

UV Flatbed printing is a form of digital printing that uses ultra-violet lights to dry or cure ink as it is printed. As the printer distributes ink on the surface of substrate material, specially designed UV lights follow close behind, curing or drying the ink instantly. Because of the outstanding smooth surface and versatility of this material, foam board is used for high-quality photo printing in photography, and in the office for meeting presentations. Another good example of this is indoor art projects, which demand high-quality output images and an extraordinary finish. Individuals and companies choose foam board UV printing when they want to create affordable yet vibrant artworks, mainly aimed to decorate interior spaces where they can be appreciated in detail.

Making a School Fun

Printing on foam board allows small companies and schools to make fantastic visual impact on viewers. Pop-up displays are an excellent example of this, often used by businesses in point-of-sale advertising to increase results and in school projects and exhibitions. Besides the high-quality images that can be printed on foam board, we must also consider its lightweight, allowing easy manipulation and installation. For this same reason, school activities or exhibitions always use it, letting kids join the games and create their artwork via using this material while keeping them safe at all times. In the meantime, foam board may be the lightest advertising material, allowing its printing to be installed on ceilings by using strings, ropes, or 3M tape. Foam board is paramount for schools or small businesses with limited space.

Trade Show Displays

Big or small companies cut costs by strategically planning to cater to the expected turnout of a given show, the size of your booth, and your primary sales objectives. For some events, they will want to take up as much visual real estate as possible and pull out all the stops to attract the most attention. They need to look for cost-effective, efficient, good-looking advertising materials when they showcase at trade fairs under a tight budget. Product durability isn’t truly a key factor since people will likely use them once or twice during a short period of their trade show displays. Foam board is one kind of easy-process advertising material. It can be sculpted by CNC cutter, framed on easels and also be hung with 3M double-sided Velcro tape. It’s a fact that foam core board doesn’t last for a long time, but its affordability allows wide ranges of applications, and it’s lightweight enough to save the work on transportation and installation process. The assembling and disassembling work will also save more manual labor. Foam board is exciting stuff.

Restaurant Business Promotion

What is today’s best recommendation? Do you have any hot new products that have been just landed? At least, you need to display your information to your customers or passersby. Some custom printed advertisements will get folks interested in your products. Visual signage with some message is the voice of your restaurant or brand. One modern use of foam board is at restaurants. Besides point-of-sale advertising, restaurants use foam core printing for their menu boards and POP-Up displays. Poster board printing’s cost efficiency and versatile is the reason we see this rising trend.
