Welcome to the Epson Stylus 7800 Printer Review.

The 24-inch Epson Stylus Pro 7800 professional wide-format printers utilize a breakthrough new 8-color ink technology (K3 ink). The Epson 7800 offers uncompromised print quality and its price point is currently unmatched in the inkjet printing industry today. Rivals such as Roland, HP, and Canon have not yet responded with a product that has singificantly affected the industry-wide growth and word-of-mouth momentum of the Epson 7800 printer.

One can utilize the Epson 7800 to produce archival prints with amazing color integrity, gloss-level, and scratch resistance. furthermore, the Epson 7800 produces professional neutral and toned black and white prints with higher density levels and virtually no metamerism or bronzing. The Epson Stylus 7800 utilizes a 1-inch wide printhead, and therefore produces almost twice the print performance of the previous model line (Epson 9600). Furthermore, the Epson 7800 delivers an astonishing resolution of 2880 x 1240 dpi. The Epson 7800 is capable of handling almost any media type, in roll or cut sheet, up to 24-inch wide.

Epson UltraChrome K3™ ink technology utilizes eight new color pigments, including a new three-level black technology, which significantly increases the potential quality output for professional color and black and white prints. According to Epson, these inks offer the widest color gamut of any ink currently available on the marketplace (an increase of approximately .2 Dmax to the Ultrachrome), and especially unique results on epson canvas. The addition of the third black ink now allows the Epson 7800 printer to produce true monochrome (black and white) inkjet prints. The new Epson k3 inks also utilize "High Gloss Mircocrystal Encapsulation Technology" which comes built into the Epson 7800 printer and serves to minimize bronzing on glossy papers.

The Epson 7800 employs the Ultrachrome inkset (8 color pigment inkset). By doing so, Epson has focused on solving some of the traditional problems with pigmented inksets, such as limited color gamut (particularly in the reds) and metamerism (prints shifting color in different lighting environments). The Ultrachrome ink drops are individually coated with resin, allowing them to sit on the coated media more smoothly and largely minimize metameristic effects. Variable drop size delivery ensures very smooth tonal range and gradations. And the reds (and almost all other colors) are incredible.
