HP offered 4800 x 2400 to top Canon’s 1200 x 1200 and Epson’s 2800 dpi. Now Epson uses the same concept of “optimized dpi” as did HP for their “4800 x 2400” so each can generate a larger number. Epson multiples its true base dpi to reach a theoretical 5760 x 1440. Numerology is an age old practice, and seems to have found its niche in inkjet printer advertising claims. Would be helpful to have a written white paper on what optimized dpi really means and how it is calculated relative to nozzle number, nozzle pitch, media feed units, and variable drop size. Whew, there is a lot more to resolution than dpi. If you are curious about dpi in your digital photos and how this relates to dpi in printers, we cover this in Nicholas Hellmuth's course on digital photography, available worldwide, in your home or office, via the Internet. What will HP and Canon unveil this year? Can they catch up? At some point Epson will come out with a 24” version of their R800 or 4000, sort of a Stylus Pro model 7700 or 7800. A wider model as 9700 or 9800 will impinge on Canon. When they come out with a 60” version, if they can increase speed, then here is serious competition for Roland, Mimaki, Mutoh, as well as what is left of Encad. Epson has raised the ante twice in a row with their Epson Stylus Pro 4000 and Stylus Photo R800. The gloss optimizer is a great idea: it may eliminate the nagging headache of differential gloss defect on colored inks or bronzing when there are large areas of dark color especially a solid black (on glossy paper with pigmented ink). The more printers that come out, the more market is created for FLAAR evaluations, reviews, and benchmarking reports. This will be our best year yet.
Epson PhotoPC P-1000 is another milestone in Epson’s triumph
