THERM-O-TYPE High Speed Foil Fusing Terms

Compressed air that is directed to separate the foil from the paper prior to the paper and/or foil advance. Used to improve foil and paper separation and to minimize/eliminate Feathering and Plugging.

Used as a foundation for Bottom Makeready Material piece(s).

Used to localize pressure between the paper, foil and Thermal Transfer Plate.

Pieces of foil that bridge between small gaps in the foil image or plug small letters.

Impression pressure adjusted to compress the coating on the Thermal Transfer Plate and the Bottom Makeready Material during impression.

Smooth, uncoated 65 to 80 lb. sheet of paper used to cover the Makeready.

The text and/or graphics that are printed within the Format.

Small pieces of foil that cling to the edges of the foil image.

Defines the area(s) where foil will be fused.

Defect in the HSFF image caused by gasses trapped within the toner image area. Most common on large solid image areas, especially on coated papers.

High Speed Foil Fusing. The process of fusing foil to toner image areas that have been printed on paper with a laser printer or copy machine.

Foil formulated to stick to toner. Does not stick to paper.

Initial contact pressure between Thermal Transfer Plate and Makeready set before running the first test sheet.

Combination of Base Sheet with Bottom Makeready Material piece(s) attached.

Noticeable effect on the paper caused by compression between the Thermal Transfer Plate and the Makeready during impression.

Paper that provides nice toner adhesion, with a surface that is non-reactive to fusing foil.

Paper that is not suitable for toner laydown or with poor toner adhesion. Paper with a surface coating/finish or chemistry that will react to the fusing foil. Paper that causes excess gassing problems.

Applying more than 100% black toner to an image area. In an extreme example: 100% laydown of CMYK.

Toner particles or spots that are outside the desired toner image area.

Fusing foil that is adhering to toner outside the Format.

Sample sheet that is marked and cut to define the area(s) (Format) where foil will be fused. Used to prepare Base Sheet/Bottom Makeready.

Used to apply heat to the paper/foil. Attaches to chase.

How the toner is fused/bonded to the sheet.
