The HP Indigo Liquid Electrophotographic process

The HP Indigo printing engine performs the following sequence:

The HP Indigo Liquid Electrophotographic process

The HP Indigo printing engine performs the following sequence:

Charging unit generates uniform charge on the electrophotographic Photo Imaging Plate.

Exposure of the plate by a scanned array of laser diodes remove charges from the image area.

One of the coloured Binary Ink Developer (BID) units engages with the plate, developing an image on it.

Ink transfers from the plate to a heated blanket using electric field

The heated blanket melts the resin particles within the ElectroInk, merging them into a smooth tacky film.

Image (in film form) transfers from the blanket to media.
Multi shot process: For each colour separation this process is repeated—this is the Multi Shot process.
The one-shot process: HP Indigo one-shot process (for web presses and heat sensitive materials)—all colour separations accumulate on the blanket
