What causes Ghosting (double image) during Transfer Printing?
Generally this is due to a shifting of paper and fabric. The shifting is typically due to non-uniform tension of the paper, fabric, or both. To eliminate the problem, vary the paper and fabric tension until optimum results are achieved. In rare instances, some fabrics and papers are not compatible and one or the other must be changed. Shifting may also occur when using an extremely slick grade of paper, defective paper, or even old paper – especially if stored in an area without climate control. In this case, extra care in pressure, tension, and speed selection must be used to reduce or eliminate the shifting. Otherwise, the paper may have inherent register defects and require substitution. Additional check points as follows: • Bearings. • That all rolls have been reinstalled, correctly pinned or bolted, turn freely, and are parallel. • That there is enough tension. • That there is enough heat in the main cylinder to create sufficient friction such that the felt holds to the heated cyl
