Digital printing technology has developed rapidly. Therefore, it is an industry that integrates multiple industries. we can see screen printing factory now can provide digital printing, and sign shops also are able to offer apparel. We see that this type of industry adaptation has occurred with the emergence of eco-solvent printers, and now we can see this in dye-sublimation printers.
What is dye sublimation printing?
Dye sublimation transfer is to use an inkjet printer equipped with transfer ink to print an image on sublimation transfer paper in mirror reversal mode, and then heat it to about 230℃ by heat press calandra. The dispersed sublimation ink on sublimation transfer paper will penetrate into the carrier in the form of vaporization, so that the color of the image on the paper can be vividly transferred to fashion textiles, home decorations, banners, mugs, metals and other materials.
Advantages of dye sublimation printing
High-quality Print Output:
The main advantage of the sublimation printer lies in the photo-level print quality.
Unique coating function:
The coating layer is a unique function of the dye sublimation paper. Since the sublimation printer is mainly used to print photo-level images, image printed on coated transfer paper, the overall color feeling will be brighter and more vivid. It also has the functions of waterproof and anti-oxidation.
Seldom block print heads:
Dye sublimation printing machine does not have the problem of ink drop spreading like UV, DTG, and the printing accuracy is very high. There are no ink dots, and there will be no nozzle clogging problem with thermal transfer ink, as we all know, sublimation ink use dispersed water-based ink, no need use white ink, keep daily maintenance, print heads seldom get clogging.
Of course, it also has limitations. Dye sublimation transfer printing only works with polyester-based fabrics. No work for 100% cotton! This is because the ink only binds to polyester material. Besides, sublimation print is a dye process, therefore it's perfect result on light color substates.
What you need pay attention to when sublimation printing?
1. Have a clean working environment:
1). The sublimation paper should be kept clean and free of dust, fingerprints, oil, etc.;
2). Ensure fabric etc substrates clean and free from dirt, debris, oil and other dirt;
2. Heat transfer temperature:
The heat transfer temperature varies based on different materials, heat press device, and the temperature of heat press area. Do not blindly pursue the higher or (the lower, the better) heat transfer temperature. Generally, the temperature is between 170°C and 240°C.
3. Heat transfer pressure:
The heat transfer pressure should be adjusted to the most appropriate level. If the pressure is too large, it is easy to damage the printed product. If it is too small, it cannot achieve better transfer effect. After adjusting to the best hot stamping pressure, the pressure adjustment should be locked to avoid changes in mass production.
4. Heat transfer time:
The transfer speed should be determined according to the specific substrates. Generally, the faster the speed, the higher the production efficiency.

A heat press is also called a bonding machine. According to the different heat pressing media, it can be divided into soldering, ACF (anisotropic conductive tape), ACP (anisotropic conductive glue), TBF (hot melt adhesive film). It is suitable for the connection of FPC (flexible circuit board), HSC (zebra paper), TAB and LCD, and PCB. So what is the principle and function of the heat press? The following is a detailed introduction.
Here is the content list:
l Principle of heat press machine
l Features of heat press machine
l Application
Pulse heating principle, due to the special design of the welding head surface of the heat press, the resistance of the welding surface is very small, and the current will pass through the cross-section with the smallest resistance. By continuously changing the voltage and adjusting the current level, it quickly heats up through the welding head. The titanium alloy indenter of the hot press ensures even temperature, rapid heating, and long service life. The pressure head is specially designed with an adjustable level to ensure that the components are evenly pressed. The temperature is numerically controlled, clear, and precise. Equipped with a digital pressure gauge, the pressure range can be preset.
1. The heat press uses pulse heating technology, with precise temperature control, and the temperature sampling frequency is 0.1s.
2. The diversified working modes of the heat press include a single working platform, rotating working platform, left and right movable platform, etc.
3. The temperature of the hot press is controlled by multi-stage heating and has a real-time temperature curve display. Its mechanism is a silicone tape index mechanism, providing accurate alignment is due to the CCD vision system
4. Large-capacity program pre-stored.
5. Touch operation interface, protected by program password.
The function of the rotary heat-press
roll-to-roll or piece-by-piece processing
The rotary heat press can be rolled or processed and transferred piece by piece. Very suitable for printing roll cloth, cloth tape or umbrella cloth, etc.
File the oil drum to 100% (save 30% of the power)
Uniform heating element temperature, no color difference in heat transfer mode.
100% seamless tube roll
The inside and outside of the drum of the heat press are precision lathes, and the outside part of the drum is finely polished and plated with iron Buddha to ensure the same temperature at each point. Optional single-layer roller and double-layer roller, double-layer roller heating is more uniform, transmission effect without color difference, saving 30%-40%. The stainless steel heating tube directly heats the oil layer, and the temperature can be raised to 200 degrees in 45 minutes.

Sublimation ink (also known as thermal transfer ink) is to make low-energy, easily sublimable disperse dyes into digital printing ink, print it on transfer paper, and heat it to make the image beautiful in a short time. Materials such as porcelain, metal, silk, chemical fiber cloth, etc. are very suitable for the market needs of personalized development and the requirements of environmental protection. So what should we pay attention to when using sublimation ink?
The following content
l What is special about water-based sublimation ink?
l What are the requirements for the operation of the characteristics of the sublimation ink?
l What should be paid attention to when preparing sublimation ink?
The production of water-based sublimation ink requires a very high level of nano-dispersion technology and nano-scale disperse dye paste. However, because disperse dyes are insoluble in water and extremely difficult to disperse, and the production of ultra-fine particle sublimation inks requires special dispersion equipment and nano-dispersion technology, few companies in the world have this technology. Water-based dye sublimation inks are widely used in personal desktop inkjet printers and commercial large-format photo printers, but they are mainly used for digital dye-sublimation ink transfer printing.
Sublimation ink has four color series of red, yellow, blue, and black. Printing materials include coated paper, coated paper, offset paper, and cardboard. Sublimation inks are widely used in single-sheet feed monochrome printing presses, two-color or multi-color offset presses. In addition, sublimation ink has two major product features: First, it can meet the needs of medium and high-speed printing. Second, under normal conditions, sublimation ink can ensure that there is no conjunctiva in the ink fountain of the printer for 36 hours, which greatly improves the efficiency of printing.
Tips for using sublimation ink: First, print out a sample for plate making and printing, and then put it into use. If there is not much deviation between the printing and the actual, you can confirm the plate making and printing sample manufacturing. However, because the sublimation ink is colored in the gas phase, it cannot be printed at the normal printing ratio.
First of all, under normal circumstances, it can be used directly on the machine;
Secondly, due to factors such as temperature, paper, printing speed, etc., it can be adjusted according to the following rules;
(a)To accelerate drying, mixed desiccant can be added, the amount is 0-2%;
(b)Equipped with sublimation ink dedicated to flush;
(c)Adjust the fluidity of sublimation ink, you can use #6 printing varnish, the dosage is 0-5%;
(d)Reduce the viscosity of the paper, basically, keep the fluidity unchanged, a detackifier can be used, the dosage is 0-5%;
(e)At the same time, reduce the viscosity and viscosity of the sublimation ink, add 52-94, and the dosage is 0-5%.
