So, set it and forget it, and don't let anyone touch the heat press until it is ti me to re move the co mpleted product. 2. For soft goods like gar ments, mouse pads, bags, and totes, make sure to use a speci cally designed spray tack ad- hesive or a tacky subli mation transfer paper. If you have s mall-for mat equip- ment, you most likely will be using a spray tack adhesive, though there are no w so me tacky paper sheets avail- able. If you have wide-for mat roll-feed equip ment, there are several different types of tacky paper available on the market, and you will need to nd the one that ts your needs for price and perfor mance. When using the spray tack adhesive with a standard subli ma- tion transfer paper, you want to spray a very ne mist on the transfer sheet, not onto the substrate. Many people point the spray can right at the transfer paper and ood it. You want to do this in an area that won't get all your equip ment sticky, as you want to hold it at least an ar m's length a way and lightly mist the paper. You don't need much at all, and since you are far a way fro m the paper, it can get messy quickly. If you can see any of the adhesive puddling up on the sheet, then you were too close to the transfer sheet and sprayed too much. That pooled up adhesive will cause defects in the transfer. The tacky pa- per and the spray tack adhesive help to eli minate ghosting by keeping the transfer sheet stuck to your substrate even when the press opens, so the transfer sheet does not move while the inks are still active. With tacky paper, it is heat activated which makes it easy to work with. T R A N S F E R LI N E S The second issue that subli mators face is the dreaded transfer paper lines. Once those sho w up on the gar ment, that ite m is ru- ined, so carefully testing your set up and getting this right is crucial. There are several steps that can be used to eli minate those lines and, typically, the ans wer is so me co mbination of those steps or, at ti mes, all of the m. I reco m mend testing to see what method or methods will work best for you and your set up. There is no real magic bullet as there are several variables like your heat press, the pressure, and te mperature used as well as the makeup of the polyester bers of that gar ment. So, here are three steps that can be used to eli minate those transfer lines. 1. The si mplest way of overco ming this is to make the paper larger than the heat press platen the gar ment is resting on. Most of the ti me the lines are caused by the thickness of the transfer paper getting i mplanted into the melted polyester. This only works if the lines are due to the paper, not the press it- self. You can also create a quick band- aid by tearing the edge of the transfer paper so it is more gradual. This will not eli minate it, but it will make it less noticeable. 2. Many ti mes, the real culprit is the heat press pressure. This will crush the gar ment and the paper, but the edge of the press is being e mbedded into your gar ment as well. First and fore most, make sure the gar ment is laying loose over the platen, and not being stretched. Then start adjusting your pressure so that it is a very light pressure but still enough to give you a good transfer. Do a quick test transfer, and if the transfer is good, then you are set. If it is light and not enough ink transfers, then slo wly increase
