Hi there Rob,
Wow. Hard at work, eh?

Just don't ask him to sell it. The image is meant more for private/dpreview forum users to look into printer's performance, as they contain some images made by our webmaster, Phil. If he is going to use it for demo prints all over the country, then it might be a problem with copyright.
Take care.

Wow. Hard at work, eh?
These series of images are 'selected' to show a printer's common limitations. I have read from Kris Kadela and others, for instance, that sunsets are notorious for inkjet printers to print clean. Summer blue sky is another one.The print from the Epson 925 by the Epson rep was a different
story. First was the print on my Kodak PPP paper. The same as at
Best Buy. The ink globbed on the sunsets and the same artifacts
appeared in the diagonal lines on image 10. He then used Epson
Matte paper (that's all he had; I guess they can't just open up a
store package of paper). He changed something in the print command
(remember we are printing directly from the Smart Media card) and
we got a borderless 8.5 x 11. Image 11 was great but started to
get some graininess on the sunsets. I suspect we enlarged too
much.
Yes, sometimes banding is more evident when you've just changed a cart.The lines (Fig 10) did not have the diamonds but still had
some artifacts. The diagonal lines (first 2) have a cross hatch
pattern to them and the vertical and horizontal bars have some
degree of banding/shading. After several false starts and a new
ink cart he finally was able to print a 5x7 (actually 2 on the
page, so they were rotated). The diamonds in fig 10 shifted to the
right two diagonal lines. The other bars still had the dark/light
banding. The overall image had some vertical banding. I suspect
this was due to the new cart; he did not do a head clean or
alignment. At this point I had taken up about 2 hours of his time
and I am convinced the Epson 925 can do a good job with image 10.
I think he was too; especially when I showed him the HP print.
Yes, there are more to just plain resolution capability. Actually, when it comes to resolution, the 600 native Canon i950 is better at it than the 1200dpi native resolution HP ps71x50. I have this confirmed by a i950 user Chris (WmAx) and I will receive his prints soon.So based on all this I will probably end up with the 7150. I know
there is more to printing then the ability to produce fine gray
lines but it does seem to be showing a limitation of the Epson. I
wonder if anyone else has tried to print your test on the Epson 925
or comparable printer. If you're interested, I can scan the test
images. I just don't know how to post them.
Ah, Epson is conscientious (sp?) this way. They will find a way to tweak it to Epson's advantage.BTW. The Epson rep was so interested in your test image he made a
copy from my smart mdia card. Hope that's ok.
