When using multiple ink colors with hot-split inks, be sure to butt-register, rather than overlay ink on ink. If ink overlay occurs, ink/color strength will be impaired when the transfer is heat fused onto the garment. Remember to continue to keep the transfer paper in plastic wrapping or in a temperature controlled oven, as moisture will invariably be absorbed by the paper between each printed color.

PolyOne currently produces color and additive concentrates and engineered polymer solutions at the Pune facility. This investment at our facility in Pune answers customers’ desire for a domestic supplier able to offer expertise in color, engineered materials and thermoplastic elastomers,” said Craig Nikrant, president, Specialty Engineered Materials, PolyOne.
