Why choose tacky sublimation paper?
Why choose tacky sublimation paper?
-- To prevent ghosting in sublimation transfer.
Now let me talk in details:
What’s tacky sublimation paper? -- Tacky sublimation paper is one type of sublimation paper, the difference is that it has a tacky field coating. The tacky field coating will be activated by heat. After the tacky field coating is activated, it will adhere to the textile very firmly, so after the transfer is finished and when you lift the press up, the paper will still firmly adhere to the textile, it prevents the paper and textile from moving, the ghosting will not occur.
The tacky sublimation paper is mostly used in stretch material such as lycra, the stretch material has a elastic, it is much easier moving during the transfer. But even though you are using the stretch material , doesn’t mean you still need to us tacky sublimation paper, that depends on the heat press machine.
What’s ghosting? -- Ghosting is a double image in sublimation transfer. After the sublimation transfer is finished, if you see a light shadow in your result, that is ghosting.
How does the ghosting comes ? There are mainly three ways :
1).You print something like a tile where the sublimation transfer paperoverhangs the object a little. When you press, ink from the overhang portion transfers either to the upper or lower platen, depending on how you are pressing the item. Now you put a shirt or anything else under the press, and it comes in contact with the ink that transferred from the previous press, it will ghost onto the new item.
2). You place your dye sublimation paper on a preheated item. As soon as the sublimation transfer paper gets warm from the preheated item, it starts transferring. If you lay the sublimation paper down then move it to adjust position, it can ghost.
3).The third reason that causes ghost is lifting the press up too fast, image drops back down. When we lift the press up, it creates some vacuum, and drop the image back down, when that happens, it shifts the media, causing the ink to transfer to another areas .
The first two types of ghosting is easy to solve, you put a teflon of oil paper during the transfer, or after you preheat the t-shirt, wait until the shirt cools down and then start the transfer process. But for the third one, it is not that easy to solve. So many clients turns to Tacky Sublimation Paper.
The third reason that causes the ghosting is because your lift the press up, the paper and textile will also go up with the heat press (electrostatic effect), so if you lift the press up too fast, it creates some vacuum , and drop the image back down, when that happens, it shifts the media, causing the ink to transfer to another area.
One thing you could notice from the above, is that the ghosting is caused when you are using the flat-bed heat press. Only in flat-bed heat press, you must lift up the press by yourself, or automatically. So when you are using roll heat press machine, no need to use tacky sublimation paper.
So when you meet next situation: 1. you are usingflat-bed heat press machine, 2. Your fabric is stretch, or easy to move.
