Which Kind of Ink is Suitable for Heat Transfer Paper?

Transfer paper allows you to print images and text on most fabrics and other suitable surfaces using an ordinary inkjet printer.  It is available in A4 and A3 sizes. Transfer paper for Inkjet is designed for use with ordinary Inkjet printers, although the question of which type of ink should be used often creates confusion.

Most types of Inkjet printers and inks would work with the transfer paper. You do not need to change anything or modify your printer in anyway.  If you have an inkjet printer at home or have access to one, it will work.
As the secret to the transfer process lies in the paper rather than the ink there is no preference as to which printer or which ink you use.  If the process is done correctly (the pack will contain all you need with clear instructions) the printed garment is going to be fully washable and durable.
You can use compatibles or originals and the result will be very similar.  Because the shirt is not a flat, shiny surface, image resolution is less important and any ink system will give great results.
There is a small benefit of using pigmented inks rather than dye based if we consider the UV stability of the image in direct sunlight but as a garment like this is likely not be worn daily in direct sunlight, there is no real significance to using one type over another.

So yes, you have read it correctly.  Any ink and any inkjet printer will allow you to transfer a personalized image onto a shirt, at home, using equipment you probably have already.  It is as simple as that!  Really.
