Roll-to-roll rotary sublimation heat press this type of rotary press is used to transfer your design to a roll of fabric. Items required to use a roll-to-roll rotary press include pre-printed transfer paper, tissue and fabric. The pre-printed transfer paper has a slight tack and is used to hold the fabric in place. The thin paper keeps sublimation ink from entering the belt around the drum.

The fabric you use will always consist of polyester, polyester blend or some other polyester coated substrate. A roll-to-roll spinning machine usually has three expansions and three rewinds. The three items listed above are loaded onto the unwinding bar of the rotary press. They gather together and pass through a press, wrapping around a heated drum. This part of the process is called “residence time”, which is where the sublimation process takes place. The rewinding rod then rolls up the now printed fabric, used dye heat transfer paper and used tissue.

High Temperature State For Rotary Heat Press-What Should You Take Care?

 

 

When you use the rotary heat press In the high temperature state, the emergency shutdown or power outage is, the first time the blanket should be transferred to the maximum distance roller to observe whether the blanket completely from the high temperature drum, the normal to ensure that the distance of 5-8cm. All the rotating bearings of the machine must be added once a week high temperature butter to ensure that the bearing rotation.

WHAT IS HEAT PRESS MACHINE OR HEAT TRANSFER MACHINE?

When I was not familiar with the digital printing industry, I thought that the heat press machine and the heat transfer machine were two different machines, but later I realized that this was not the case. Today, I will introduce what is a heat press machine.

rotary heat transfer machine

A heat press machine is a machine engineered to imprint a design or graphic on a substrate, such as a t-shirt, with the application of heat and pressure for a preset period of time. While heat presses are often used to apply designs to fabrics, they can also be used to imprint designs on mugs, plates, jigsaw puzzles, and other products.

Both manual and automatic heat presses are widely available. A new style of press that is semi-automatic has entered the market as well, allowing for a manual closing process with an automatic opening. Digital technology in newer machines enables precise control of heat and pressure levels and timing. The most common types of heat press employ a flat platen to apply heat and pressure to the substrate.

Another design type a “draw style press” allows for the bottom platen to be pulled out like a drawer away from the heat for preparation of the graphic. Vacuum presses utilise air pressure to provide the necessary force and can achieve high psi ratings.

Most heat presses currently on the market use an aluminum upper-heating element with a heat rod cast into the aluminum or a heating wire attached to the element. For high-volume operations involving the continuous imprinting of items, automatic shuttle transfer presses are used. The substrates to be imprinted are continuously loaded onto the lower platen and shuttled under the heat platen, which then applies the necessary heat and pressure.

The pattern is printed in sublimation ink on sublimation paper which allows the pattern to transfer. You can get some highly effective patterns and great effects using this technique.

What are the color mixing methods of digital printing machine?

Digital printing refers to the printing of expected patterns and colors on textiles through digital technology. Digital printing is used for printing proofing and small batch production, both convenient and cost saving, which mainly saves the process and cost of plate making and network making. The key practical techniques for proofing and production of digital printing are color, graphics and color fastness. The expression of pattern can be achieved through color separation and design software. Color can be achieved through screen display, color card toning, color measurement, experience toning and other methods.

The following mainly introduces four kinds of digital printing machine toning method, for your reference.

1. Screen display. To adjust the color of an image by adjusting the color displayed on the screen, usually by selecting or adjusting the color on the screen through the color menu. This method is very useful when matching colors or starting to mix colors. It is a common method used by designers. However, because the hair color principle of fluorescent screen is different from the hair color principle of dyes on fabrics, the colors displayed on the screen cannot be fully expressed by dyes on fabrics, and the subtle differences between the colors displayed by dyes cannot be clearly displayed on the screen. Therefore, this is a general method of color mixing, and cannot be used as an exact color mixing.

2. Color card toning method. Adjust colors by comparing the colors in the color card.

3. Color measurement. With the help of color measuring instrument, the target color block is measured, and the color measurement results are input into the computer, and then the color is printed. This method USES instruments to determine color and thus excludes many human and environmental factors.

4. Empirical toning method. The speed of its toning process, the accuracy of the results completely depends on this need operators in the daily work of continuous analysis, accumulation.

Digital printing technology and traditional printing technology are two completely different printing mechanism, digital printing machine proofing has become the mainstream production mode in the western printing industry. At present, more than 90% of the printing enterprises in Europe have adopted digital printing machine for proofing. These enterprises generally believe that digital printing machine has rapid response, low cost and good consistency of proofing effect. Digital printing machine has become an indispensable tool for the printing industry in Europe.

How to solve the transfer printing problem of natural fibers?

Because transfer printing has many advantages and the products produced are also of great commercial value, it has developed rapidly since it was put into production in the 1960s. However, because it is only suitable for synthetic fibers with clear glass transition temperature, its development is hindered and can not be applied to natural fibers. How to solve the transfer printing problem of natural fibers has become a hot research topic at home and abroad.

So far, the main solutions are as follows:

1) Grafting denaturation, such as acetylation, benzoylation, etc. This allows the fibers to accept disperse dyes.

2) Surface polymerization. This method is to polymerize macromolecule materials on the surface of fabrics, so as to accept disperse dyes like synthetic fibers, such as polyester method, styrene method and so on.

3) Fiber expansion. Expansion phenomena in amorphous region of heated polyester fibers were simulated and disperse dye gas was admitted. However, the fastness is insufficient due to the lack of fixation with fibers. So this method can only be used in conjunction with other methods of fixing dyes. Polyethylene glycol (200 molecular weight) is generally used for fiber extrusion. It is not only an extruder for cotton fibers, but also a solvent for disperse dyes.

The common feature of the above methods is that natural fibre fabrics must be pretreated before transfer printing, which increases the production process and cost. More importantly, in order to clean the remaining non-functional materials on fabrics, it is necessary to wash and dry them. In this way, it is impossible to eliminate wastewater discharge and increase the consumption of heating energy, which makes it difficult to get rid of the heavy burden of traditional printing and dyeing production.

This natural fiber transfer printing method does not retain the characteristics of synthetic fiber transfer printing method, and is difficult to be accepted by manufacturers. Some methods still leave harmful substances such as formaldehyde on fabrics, which do not meet the requirements of environmental protection. In addition, after printing, many fabrics migrate over time, resulting in blurred patterns. Therefore, although this method has been applied, it is not ideal. Others use spraying pretreatment liquid on the part of natural fiber clothing and printing after drying.
