Topic about the Consumables Materials for DTF Printer

1.     About the printer

The main parts on the machine is printer head and mainboard,

1. a)     Mainboard: hoson is the occupate 75% in the market,and the next is Sen yang which is high cost performance.If your budget is limited we suggest you to choose this.

2. b)     Printer head: the most stable one is EPSON I3200 but it is expensive, and the cheap model is XP600.The most accompany is Hoson mainboard+Epson I3200.

There are different amount on printer head.There are 2heads,4heads and 8head.The more heads is more printer faster and more high quality printing.
2Heads: 1head for colorful inks, 1head for white inks
4Heads: 2heads for colorful inks,2head for white inks
8Heads: 4heads for colorful inks,4head for white inks

2.Hot melt powder

(1) Melting range (melting point): 115-130 ℃

(2) Ingredients: TPU (polyurethane)

(3) Washing resistance grade (GB 5 is the best): 40 ℃ water washing grade 4, 60 ℃ water washing grade 4, dry cleaning and drying grade 4

(4) Pressing condition: Time: 8-15 seconds Temperature: 120-165 Pressure: 2-4KG

(5) Anti-static, anti-oil, good elasticity, tensile resistance, strong washing fastness, normal drying without cracking (for washing machine with drying function)

3.About ink:

the main raw materials are resin (waterborne polyurethane), titanium dioxide, and other additives

At present, as the main raw material of white ink, resin is the W-6110 resin produced by Mitsui in Japan. This white ink is the best and most stable resin currently used. Enterprises such as Ink Bank and Tianwei still choose W-6110 as the raw material in resin selection. This is also the fundamental reason for the high cost of white ink. In terms of performance, 6110 has an effect that other resins can't achieve, no matter in elasticity, coverage and whiteness. At present, white ink is also being localized. Compared with imported resin, there will also be a big gap in cost, but there is still a big difference in performance with imported resin. At present, Chinese ink factories still mainly rely on imported resin, but some factories will use domestic or even reduce the resin content of ink (the normal resin content of 1L ink cannot be less than 20%) to control the production cost, thus reducing the sales price of ink, But the performance and stability will be greatly reduced!

4.PET film

(1) The bottom film is a kind of polymer material, referred to as PET film

(2) At present, there are mainly two kinds of films on the market: one is oily film, the other is water-based film (generally speaking, it is not recommended to tell the customer what kind of printing film it is, because the solvent is added to the oily film, which may have environmental requirements in some foreign regions)

(3) On the basis of water-based and oil-based films, different coating processes are derived, namely, three-in-one coating, water-based coating and oil-based coating.

(4) In the sense of perception, the pattern picture can be divided into:; Matte, bright, single-sided and double-sided (mostly matte in the market)

(5) Oily coating film: this film is a relatively mature product for DTP, and is also a mainstream product in the market. However, due to the complex coating process and relatively high cost, the normal coating needs to be repeated for more than 4 times, but the coating is stable and will not be affected by the weather, temperature and humidity, or there is poor separation, powder rising, etc

(6) Water-based film: The coating materials used are water-based and soluble in water, so they are relatively environmentally friendly. However, the coating formula is unstable and is greatly affected by environmental factors. There are often problems such as powder swelling, water edge, inability to tear, poor washing fastness, poor ink absorption, etc

(7) Three-in-one film: the process derived from the above two processes is to mix all the coatings together for coating, which will be lower in cost than the above two coating processes, but it is extremely unstable, because it is difficult to ensure the smoothness of the coating when all the coatings are mixed together for coating, mainly resulting in problems such as coating loss, poor color fastness, ink flow, etc. At present, there is no good film factory in China
