This video shows you what happens when we don’t use the appropriate paper.
In this case we transfer directly to the protective paper. The result shows the quantity of gas (ink) ink that has gone through the protective paper.

Not using the appropriate protection paper may entail a waste of ink, transfer paper, printing time, fabrics, etc.
