Epson's Variable-sized Droplet Technology and MicroPiezo(tm) print head ensure that this printer provides outstanding photographic reproduction at fast speeds to satisfy the most demanding photographers. The UltraChrome Hi-Gloss pigment ink has also been designed for unsurpassed print permanence in an A3 photo printer, with a lightfastness estimated* at over 80 years for glossy papers and over 100 years on matte medias; a flexibility and durability that truly rivals silver halide.
The Epson Stylus Photo R1800 delivers unsurpassed print performance in an A3 photo printer. High definition images are achieved through Epson's UltraChrome(tm) Hi-Gloss pigment ink, which is delivered in 1.5 picolitre (pl) droplets to capture the finest details. It includes Cyan, Magenta, Yellow, Blue, Red, Photo Black, Matte Black and Gloss Optimizer Technology. The inclusion of red and blue ink increases the colour gamut and colour space, primarily making it closer (and in some areas wider) than Silver Halide, essential for photographers requiring premium colour reproduction. The Gloss Optimizer provides a smooth gloss finish to prints for exceptional premium glossy and semi-gloss prints.
I am looking for an A3 photo printer. I've spent an eternity on the web reading 'professional' and user reviews. I think I am becoming more confused, rather than less.
