What makes the HP Indigo digital press unique
Digital printing is a term often misunderstood and used to generalize what is a diverse range of output devices. For example, a desktop inkjet is a digital printer. In general, a digital printer can be considered as any device that can change the content, up to 100%, from sheet to sheet without stopping.
Compared to DI presses. Direct Imaging, or DI, presses are a class of press which is often mistakenly referred to as digital. DI presses use on-press imaging technologies to create an image onto a lithographic printing plate. They do not feature collating, duplexing or variable imaging capabilities like the HP Indigo digital press. Once the plates are imaged on a DI press, the process reverts to conventional printing with its inherent limitations. Compared to dry toner. The other main digital color press technology is the xerographic (dry toner) process, commonly found in laser printers and color copiers.
The toner process is typically characterized by a lack of print quality. Dry toner particles range between 7 to 9 microns in size and struggle to reproduce fine details and acceptable colors. With dry toners it is difficult to match the surface gloss of a substrate, usually giving the image a glossy appearance on a matte paper and an ultra-glossy appearance on a glossy paper. The process also attracts a lot of static that is transferred to the paper and can cause significant problems and waste in the finishing process.
The dry toner process limits your choices and creativity as a designer in terms of print quality, paper quality and finishing techniques. The HP Indigo digital press is the only digital printing technology that can equal or exceed the quality, color range and substrate compatibility of conventional offset printing. It is also the only digital technology that can print up to seven colors, including extended gamut printing or spot colors, that help you produce eye-catching images or match clients' corporate brand colors.
