Overview

This chapter contains a tour of the HP Indigo press 3050 and a description of the press
workflow.
The HP Indigo press 3050 is a sheet-fed digital offset color press that incorporates the
patented HP ElectroInk liquid ink technology and high-speed electronic imaging to
produce fully-finished, high-volume, high-quality color print jobs. The press features an
intuitive and user-friendly interface, provides diagnostic screens that take the guess work
out of printing, accepts very large files, and simplifies the entire archiving process.

Digital offset color printing

Digital offset color printing is the HP Indigo electronic printing process that combines
high-performance digital imaging technology with the liquid ink offset printing process.
The merging of electronic imaging with the properties of liquid ink offset printing combines
the flexibility of on-demand electronic printing with the quality of offset printing.
As in offset printing, digital offset color printing transfers the inked image from the image
carrier to a blanket, and from the blanket to the substrate. However, unlike offset printing,
digital offset color printing creates a different image with each revolution without the use of
film separations or printing plates.
The press is equipped with an embedded HP Indigo raster image processor (RIP).
The HP Indigo embedded RIP enables you to process PostScript or portable document
format (PDF) files at your press station. The HP Indigo RIP is fast, has proofing and
previewing capabilities, and lets you perform light editing. It RIPs the jobs immediately
upon arrival at the station.
The press supports the HP Indigo proprietary Swift Native Accelerated Personalization
(SNAP) technology. SNAP technology enables you to print large database driven
personalization jobs without delay.
