Choosing between UV-LED and Water-based Inkjet Inks for Digital Printing

UV-LED and aqueous inks are the leading high-quality inkjet inks for the digital printing industry because they produce fast, efficient and cost-effective results. Compatible with a wide range of applications, both options can enhance print productivity. Understanding the distinct differences and benefits each ink offers can help you determine which inkjet technology is best for your business and market needs. The following information discusses what each ink type is and some of the key differences between them.

 

UV-LED Inkjet Inks

UV inkjet inks are liquid until the ink is exposed to UV-LED light shortly after it touches the substrate. This process cures the ink almost immediately and forms a durable film on top of the substrate. The ink is not absorbed into the substrate, but cures on top of the material. UV-LED lamps provide a deep penetrating light source that allows for better adhesion to thicker substrates. This often results in UV inks that produce vibrant, long-lasting colors on the final printed product, making them ideal for applications with a long shelf life.

 

Advantages

❈ Resistant to scratching, abrasion and rubbing

❈ Ability to print on flexible and more rigid substrates

❈ Can be used in outdoor and industrial environments

❈ Sharp contrast and color consistency

❈ Resistant to water, chemicals, and solvents


Disadvantages

❈ Incompatible with highly absorbent substrates

❈ Need to consider ink regulations and safety compliance standards

❈ Capital investment may be high at first

 

 Choosing between UV-LED and Water-based Inkjet Inks

 

Water-based inkjet inks

Water-based inkjet inks are made from water, rather than other components such as plastic or PVC. Water-based inks use water as a medium to bring pigments (colors) into the substrate. In contrast to UV-LED, water-based inks require a longer drying time during the production process. Due to the low chemical risk associated with water-based inkjet inks, this inkjet ink technology is well suited for primary and secondary packaging applications, including food packaging production.

Advantages

❈ Wide application compatibility

❈ Environmentally friendly

❈ High possibility of meeting different safety regulations

❈ Low maintenance required when running on press

Disadvantages

❈ Incompatible with long-term outdoor applications, best suited for indoor use

❈ Application on some substrates may be difficult due to water content

❈ Longer drying process

The process of making different types of inks

One of the most important, integral and indivisible factors in ink manufacturing is   the type of pigment used in the ink . Everything from the appearance of the ink to the characteristics of the ink to the way it lasts depends on the pigments used to color the ink. Therefore, when you want to know the right type of ink for your requirements, it is important to know the type of pigment used in the ink. With the wide variety of inks on the market, it can be difficult to know which ink is best for the purpose you have in mind. When it comes time to print, having a guide to pigments and inks makes it easier for people to make the right choice.   Water-based inks and their pigments. While inks have many uses and they represent many businesses, one of the most common commercial uses of ink is for printing paper. Copiers, printers, and other such printing devices utilize digital printing methods, and the inks used for these purposes are usually water-based inks. Experts such as pigm...

How to print DTF (direct to film) Sublimation step by step

  Print images for sublimation on textiles, using a film and   DTF printing technique ! This is an introduction to a new printing technique called DTF printing also known as direct to film printing. This printing technique brings more possibilities to textile printing as it can be fully applied on dark color and light color fabrics such as nylon, polyester, cotton, canvas, leather, and others.  It is a method of sublimation of small designs whose results are in full color. The designs will have a very soft and smooth texture, they will be stretchable, and long-lasting because they will be resistant to washing.   The DTF print process requires: ● DTFprinter/ Epson L805 or Epson L1800 (They must be adapted) ●  DTF inks ● DTF powder ● DTF film  ● Special design software (ACRORIP, EKprint, Kothari RIP) ● Heat press The dtf film comes in two sizes: the A4 size, and the A3 size which allows you to print larger format images...

What is DTF Printing?

DTF printing is direct-to-film printing, which is a supplement to the inkjet garment decoration process. Even white ink does not require pretreatment. It is very convenient for customized DIY printing market. What is DTF? DTF is an alternative printing process for DTG. The film was printed using a specific type of water-based ink.It was then dried with powdered glue on the back and then heat cured for storage or immediate use. One of the benefits of DTF is that there is no need to use pretreatment. DTF cannot do this. The powdered glue does the job for you. After hot pressing, the soft water-based ink is transferred to the garment in about 15 seconds. Transfer is most suitable for polyester and other non-cotton fabrics that are difficult to print with traditional DTG printing. DTG is mainly designed for cotton garments printing. DTF is difficult to replace DTG for cotton printing. However, due to its low level of investment in its independent version or fully automated system for mass ...
