SITECH UV Inkjet Ink

Sitech Specialty Chemicals is specialized in manufacturing of UV and LED UV inkjet ink. We established in 2013 with the headquarter and R & D Department located in Taiwan. ​

Sitech is the abbreviation of Sun Rise Industrial Technology. Sun Rise is well known in paper and textile industries, specialized in manufacturing optical brighteners , concentrated pigment slurry and resins. With almost 40 years of the experience of manufacturing dispersion of optical brighteners and pigment slurry, Sitech has developed technologies of controlling particle size of the pigment slurries, stabilities of dispersion, and viscosities and surface tension of the pigment slurries.​

We are capable of controlling the viscosity, surface tension, surface charge, flexibility and drying speed of the UV and LED UV inks in accordance to the specifications of the print head and the inkjet printer.​

Base on these, we position ourselves more than just an ink supplier to the industry. And because we understand the chemistry inside out, we are able to design inks for any applications that can be related to inkjet printing industry. We are proud to say our creation & innovation ability is extraordinary. At present, we OEM and ODM inks for many famous brands and also looking forward your inquires for any new applications or developments to create the win-win situation.​

UV AND LED UV INKJET INK

Sitech is not just a UV inkjet ink maker, but also a raw material supplier for all UV inkjet ink makers globally. Founded by chemists who are expertise in surface chemistry and organic synthesis, Sitech is capable of designing and producing the most stable UV inkjet inks ​

​We are providing more than 2 dozen formulations to different industries.​

  • Vacuum Forming
  • Home Furniture
  • Advertising Banner
  • Single Pass​
  • Cell Phone Case Embossed Printing for​TPU/ABS/PC/ GLASS
  • Low UV Banding/High Speed Printing Solution​

Latex Inkjet Ink

Latex inkjet inks is designed to replace the conventional solvent and eco-solvent inks. Unlike solvent inks, latex inks can adhere to almost any substrate available. In comparison to UV inks, it provides much better adhesion on substrates. By far, it is the most versatile, odorless and safe inkjet ink for digital printing.​

  • Traffic Sign on prismatic reflective​ sheet​
  • Backlit/Frontlit
  • Wall Paper
  • Leather​
  • Paper

3D Printing Ink

Sitech’s technology is based on our experience in UV technology. We design the cured polymers based on your requirements, we work out the eventual polymer’s tensile strength, hardness, glass transition point and etc. to fit your needs.​

  • SLA/DLP
  • Inkjet 3D Printing

Q&A

Ans: The biggest difference is that UV and UV LED inkjet printer use different light sources to cure inks. Because of different light sources, the emission wavelength for curing the inks are different.

The wavelength for curing UV inks is between 245nm~405nm. While the UV light is emitted, the traditional mercury lamp would generate heat along with ozone. Heat and ozone may cause warpage of the printing media.

On the contrary, LED-UV lamp, which generates UV light at various wavelength, does not generate heat and ozone.

Because of different light sources, the formulation of UV and UV LED inks are quite different. It is strongly recommended to discuss with us your light sources before we supply you the most suitable ink.

Ans: When a printhead is clogged, it may be due to the following reasons:

1. Instability of Inks: Disequilibrium of the forces surrounding each pigment particles would cause the pigment particles to aggregate or/and agglomerate. The aggregation or agglomeration of the pigment particle would form a much larger and viscous gel.

2. Exposure of Light: When Inks are exposed to light, depending on the duration of exposure, the inks will gradually to polymerize and form larger particles. It is because light, which often contents UV light, would trigger the monomers in the inks to polymerize. In other word, inks are cured.

3. Dust: Dust in the air may enter the printing system and clog the printhead.
By using Sitech Flush Cleaner is able to remove these clogged inks. Please contact us for further information.

Ans:One of the key ingredients to success in digital printing is the use of the correct ICC Profile. Using the wrong profile can cause color shifts and production

ICC stands for International Color Consortium, an industry group devoted to standardizing color in commercial printing applications. An ICC profile is an element in RIP (Raster Image Software) software that allows the software to coordinate the physical attributes of your printer, print head, ink, and media to obtain correct and consistent color. ICC profiles contain several elements including rendering intents, dithering patterns, ink levels, etc. To obtain an ICC profile, please contact us for further information. There are input and output profiles. We’re dealing with output profiles here which are designed to control the quality of the images you output to your digital print devices.
