Ghosting is a common failure during the heat transfer calender transfer. As you pursue ending up being a skilled dye-sublimation printer, you may encounter several barriers such as your transfer coming out blurred, dull, or discolored. In the following, we have compiled some of the remedies connected with dye-sublimation printing you may experience.
1. The cushion material (such as cotton towel, sponge, cardboard, and so on) under the level textile heat transfer calender soaks up the ink wetness throughout the transfer process, which will certainly trigger too much water vapor throughout the transfer, as well as it will certainly make the picture color when it is moved to the cloth. It ends up being lighter or presents a part of aerosol or water streak-like problem.
So, it can be boosted by vaporizing the wetness on the pad cotton towel prior to transfer as well as during the transfer procedure. If possible, it must be prompt to change the pillow product.
2. The printed photos and also the material that to be moved need to not perspire as much as possible. Or else, the paper will certainly become soft as well as wrinkled throughout the transfer, particularly when the roller press just makes the paper soft as well as wrinkled, and red stripes will certainly appear on the transferred material. And the transfer rate will be lower, the color of the picture will certainly not be beautiful, and the rundown of the picture will thaw when it is serious. There will certainly be a shade difference in the cloth of dry transfer and also damp transfer– a lot more extreme the damp, the more serious the scenario.
As a result of the above aspects, the printed paper (to be transferred) and also textile should be positioned in a completely dry area, as well as the moisture needs to be regulated below 60%.
3. When moving under a level press, ghosting in some cases happens. The reason is that the paper is relatively level throughout the thermal transfer, and it will not bend immediately under the press, as well as the paper and also fabric can be squashed. Nonetheless, when the heat press plate is lifted throughout the thermal transfer, the paper will certainly be adsorbed on the upper press plate together with the fabric, and then fall down. Right now, when the high-temperature transfer paper falls on the material, the additional transfer will take place, causing light ghost pictures.
① Minimize the climb speed. We can change the cylinder (or hydraulic cylinder) rate control valve (throttle valve or throttle shut off) on the heat transfer calender, and deny the valve that regulates the stress plate’s lifting to make the training speed of the stress plate slower. By doing this, when the pressure plate is raised, the paper, as well as the cloth, are not easily gobbled with each other, which can protect against the issue of ghosting triggered by the additional transfer from falling off.
② Dip the four corners in water. If the transfer paper is smaller than the fabric, you can use a little water (a tiny dot, ≤ 0.5 square centimeters) to the four edges of the transfer paper without printing images, and afterward, cover it on the textile for transfer. After the transfer, the bond will be no misalignment with the textile to cause secondary transfer ghosting. After the transfer, if the put on the fabric is shed with water, it can be wiped off with water.
③ Whitewash method. If the transfer paper is larger than the cloth as well as can conceal the clothes look, the paper and towel are usually not gobbled by the warm pushing plate. This is due to the fact that the physical aspect of being gobbled is the electrostatic impact of the cloth. When the paper covers the cloth, the paper obstructed the electrostatic impact from the fabric. As a result, the textile will certainly not suck up and also diminish the secondary transfer.
④ Usage of unique adhesive transfer paper. It is the best way to avoid ghosting from using unique adhesive transfer paper. The adhesive transfer paper will be pasted with the material during transfer, to make sure that no matter how the paper and material are gobbled and also down, the paper and also material will constantly stick together. At the same time, the possibility of moving as well as ghosting is gotten rid of, and also the selection of glue paper can significantly boost the comfort of operation and also the pass price of mass production.
Side ghosting describes the fact that superficial shadows appear on the left and appropriate sides of the dots’ axis or lines, as well as their positions, are reasonably taken care of.
The thrust bearing of the roll to roll heat transfer calender countered printing cylinder is a component to stop the cylinder’s axial motion. If the thrust bearing is put on or loosened up, there is a space, under the action of the axial thrust of the helical gear, the cylinder will certainly relocate series to create straight ghosting, multi-color. The machine’s axial fine-tuning mechanism hangs, as well as the bearings are worn out, which will certainly cause the printing plate cylinder as well as the covering cylindrical tube to create relative axial variation under the regular functioning condition of the printing press, thus creating side ghosting. Service: Focus on the upkeep of the printing machine at regular times, and it can be prevented if the bearings with severe wear are discovered to be replaced in time.
This kind of failure is generally because of the imprecise paper transfer brought on by the squeegee’s axial activity, which causes ghost pictures. Remedy: Change the space in between the limited ring at both ends of the roller gripper shaft as well as the sleeve’s end surface area.
As a result of the lotus leaf paper’s lengthy paper edge, under the printing pressure of the initial shade, it presses to the routing edge as well as gradually relocates inward. When the first shade is pushed into the second shade, it was originally squeezed by the initial color. Journalism paper is released once again. This folding and also release quantity is arbitrary, resulting in the imprint of the previous covering continuing to be on the next device and the present imprint not being entirely overlapped, triggering ghosting This type of ghosting primarily occurs in both edges of the routing edge of the initial shade, and also there is no center. The solution: air-dry the paper to make the paper smoother before printing.
Longitudinal ghosting describes the fact that the shallow darkness shows up in the front and also back of the dots or lines in the axial instructions, as well as their settings are taken care of. The ghosts can be light or heavy, separated right into the partial and whole design.
Mean the pressure in between the rollers is as well large or the roller radius is not set up properly. In that instance, the rubber towel will certainly have a big variation under the action of the rubbing of the imprinting surface area, as well as it can not be totally reset after each transfer, leading to ghost pictures. Option: Fairly adjust the lining data of the printing plate cylinder and covering cylinder to make them fulfill the demands of synchronous rolling, under the property of guaranteeing ink transfer, minimize printing pressure.
The blanket of rotary heat transfer calender is not tightly extended, the displacement is huge throughout the moving procedure, and also can not be reset by the tightening pressure, there are 2 scenarios when the covering is not firmly stretched: one is that the total stretch is not tight, creating a big location of the ghost; The second is that the blanket is reduced manipulated or the iron splint is not correctly fashioned, causing partial tension as well as partial ghosting. This type of ghosting primarily happens in the tracking component. Normally, the ghosting just occurs in the very first lots of sheets. Service: If the blanket is not limited as a whole, simply re-tighten; if the part is not tight, inspect whether the covering is cut manipulated, or not mounted effectively, find out the factor, and fix it.
Remedy: Tighten up the printing plate; if the printing plate is cracked, you require to change the home plate.
Uneven ghosting describes the imprint ghosting (neither straight ghosting neither longitudinal ghosting) that takes place when double-diameter cylinder balanced out printing presses are in continual operation. Uneven ghosting is because of the printing press itself as well as the printing process’s procedure. The major factor for the machine is the not enough setup precision of the two pairs of double-diameter rollers. The printing process procedure troubles are mainly due to the deterioration of the tooth pads that have been made use of for a very long time, as well as the accuracy is reduced. Pay much more attention to the device’s upkeep at average times to keep the device in an excellent running state, the ghosting scenario will certainly be managed, and also the quality of the printed item will be boosted.

A heat press machine is used to transfer designs to many different which utilizes three basic principles print our graphics on textile. These principles are time, pressure, and temperature. We need to set these aspects to the recommend accurate values before we start printing on our fabric. Make a slight mistake in the settings, and we will end up with an improperly printed textile, or a crooked printing.
Generally, our heat transfer machine comes with directions of use. These guidelines incorporate a chart that gives us full details about the correct time, pressure, and temperature values to use for different fabrics. Additionally, we’ve broken down the suitable temperature and time settings based on various factors:
| Material | Temperature/ Degree | Time/ Minute |
| Polyester | 270 | 10 |
| Multi-Purpose fabrics | 350 | 10-12 |
| Cotton and denim | 380 | 15 |
| Stretch fabric | 335 | 12-24 |
| High quality graphic | 305 | 5 |
| T-shirts / Sweaters | 365-370 | 10-12 |
| Full color graphic | 350 | 10-12 |
| Vintage / Faded look | 350 | 10 |
| Reflective | 305 | 10 |
| Glow in the Dark transfer | 350 | 10-20 |
| Glitter / textured designs | 350 | 15 |
| Metallic look | 320 | 10 |
| Difficult fabrics | 330 | 15 |
( Note: Due to the versatility of a heat press machine, and the multiple uses it has, we may find that the item you want to print comes in two different categories. For example, we may want to use a glitter design on a t-shirt. In cases like this, try the lower temperature first, as using too much heat can damage the overall design.)
That’s it for our complete heat press calender temperature guide. The list contains the ideal temperature and timer settings we should use for almost all the fabrics you might encounter when doing heat transfer. If we couple the above information with your device user manual, we will have all the information we need to operate our machine using the correct temperatures.

Heat Press Machiner are available that vary in size and application. Despite these variations, they all function the same way. At 400 degree Fahrenheit, they simultaneously heat the ink on the transfer paper and the polymer fibers within the substrate, enabling the transfer of ink-to-media. After about a minute. The heat is removed and the transfer paper is peeled off, leaving behind a permanent, full-color graphic on the substrate.
Although this may sound daunting to some, it’s really a simple and effective method to apply graphics to fabrics and other media. In comparison to traditional print methods, it saves hours and even days of print work and with the right machine, the quality results are comparable to screen-printing.
Once you’ve spent much money on a dye sublimation printer, you have to consider at least matching this price for your press if you plan to create large format signs and graphics for the long-term. A reliable large format press should last decades and fulfill an increasing sublimation output as your business and printing machinery grows. Invest in reliable quality heat press and plan for business growth.
Of the heat press devices available, there are four main types. Then you can know which type heat transfer printing machine is best suitable for your business?
If you’re planning to sublimate on t-shirts and small items such as caps, mugs, plates, and shoes. Then you might not need to spend a great deal on a heat press. Expect to pay around $1,500 and upwards for a decent 16”x20” full-size shirt press from brands that have heat and pressure controls.
Heat Transfer Calender are large format presses that are built for flags, large exterior banners. And other large soft-signage applications, as well as day-to-day soft signage and fabric sublimation. With the addition of table attachment to your calender unit, users can cut and sew apparel pieces.
Although they can’t effectively manage the kind of rolls and fabric sizes that a Calendar heat press can. Flatbed style heat presses are versatile presses that can heat transfer onto fabric as well as aluminum, hardboard, floor mats and other unique media.
A 3D vacuum heat press is a compact desktop machine that allows heat transfer onto materials with a curved edge or shape. Sublimation blanks and pre-treated objects, such as smart phone covers, mugs, ceramic plates, picture frames, sporting goods, buttons and others are available for sublimation by this handy device.
