What brand of paper are you using. Are there not instructions?
Unless you are using Imageclip for inkjet you will have polymer window in some form. Some may be less but the window will be visible unless you trim the transfer close to the contour of the image.Ive been using a heat press for about a month now ive had some problems with getting the designs to go on with all the ink what temperature should my heat press be at and how long should i press the shirt for dealing with white shirts and transfer paper that puts the design directly on to the shirt with just the ink
Is that centigrade? If not that is too low. Typically the temp is around 358F to 375F Raise the time to 30 seconds and very heavy pressure.im using McLogan super stretchy Light inkjet transfer paper i usually use about 185 degrees and press for 15 sec but the design doesnt really go on to well
