New process of ceramic tile printing: inkjet technology improves printing quality
- Apr 24, 2018 -

At present, the domestic large ceramic tile production is to adopt more flat screen printing and rotary screen printing of these two kinds of process, however, these two kinds of printing process requires a lot of time to prepare and a lot of artificial inputs, while the industrial printing technology development has very mature, but the printing screen close to the method of ceramic tile, but on the yield and quality of printing ceramic tile production an important impact.

Rapidly from the perspectives of the market changes of observing analysis, also can see due to increased global competition, and the rising cost pressure, make the traditional craft of ceramic tile production can't keep up with the development and changes of the situation.

  Although industrial silk printing has many advantages over manual printing, there are still many defects in this batch of mechanical copying methods. As a result, the ceramic community soon realized the benefits of using contactless printing technology, especially the piezoelectric inkjet technology that would bring great benefits to the industry.

Adopting inkjet technology can improve printing process production speed, reduce cost, maintain and improve the quality of ceramic printing products, support the product's versatility and increase production. In short, inkjet technology can meet the requirements of different markets and pave the way for new opportunities and new applications. Although digital jet printing technology can not completely replace the traditional production technology, the practice proves that the use of digital jet printing technology can make the printing of ceramic tiles obtain a lot of benefits.

At present all kinds of markets are to shorten the ceramic tile production process is put forward higher request, ceramic tile manufacturers have to seek to provide high printing image quality, high production efficiency and has the versatility of printing printing equipment. Compared with other transfer printing systems, digital inkjet technology has more advantages in meeting these requirements. These advantages include simplified manufacturing operations, improved image accuracy, extended working life and wider application of ink.

Compared with the silk screen printing ink, inkjet printing ink used with low viscosity, this makes the how to control the composition of high solid ink (that is, the higher the pigment content), while maintaining uninterrupted contact inkjet printing, become a decisive factor of success, and is also a challenge for inkjet solutions provider. For nearly 30 years, piezoelectric inkjet technology, for the printing system manufacturers and end users are of great interest, and specially designed to meet the industrialized production of strict requirements, mainly in the design at the same time take into account the need to withstand harsh environmental conditions.

Among them, the printing head has the ability of continuous high frequency ink jet and the application of various kinds of ink, and it also meets the advantages of high accuracy and high speed, which is widely accepted by merchants and users. The precision of droplet drop is the base of high quality image, and the low precision of droplet drop can result in blurred image and defective point.

While maintaining the inkjet linearity, this ability to high frequency (over 40 kh) constant encouragement inkjet ability give machine designers have more freedom, allowing the nozzle and ceramic tile or other substrates with a wide gap between the distance. The gap here refers to the distance between the print head nozzle and the substrate surface. The increase in clearance distance provides greater flexibility to accommodate different substrate levels and surface roughness. The increase of clearance distance also reduces the risk of damage to print head by accidental contact with the substrate surface during printing. With two different print head in the same clearance distance for actual ink-jet printing, the work under the same high-speed printing speed, which USES high liquid drop speed and better inkjet print head device to obtain obvious linear work better picture quality.
