Bill Atkinson profile problem

[Peterretep]

I'm looking for help with a problem I'm having using a Bill Atkinson profile for luster paper, PLU 2, on a Epson 7600 printer.
The problem arose after I formatted my G5, reinstalled programs and drivers. I have the current Epson driver and downloaded Bills profiles. The problem I'm having is only when using the PLU 2 profile which gave me the best prints prior to the formatting. When I now use this profile the resulting image is streaked with brown to yellow areas most noticable in the sky but strong enough to be clearly visible on more busy areas of a print. I am now using a profile downloaded from Inkjet Arts which is good but not as good as Bill's. Does anyone have any idea as to what can be wrong. I have deleted and downloaded Bills profiles several times with the same results. As before the problem arose, I'm printing  on Ilford Gallerie Pearl with Ultrachrome inks, photo black. Thanks in advance for any input into this problem.

Streaks are most likely a clogged nozzle, or the paper advancementment adjustment (how far the paper moves between each pass of the head) being set incorrectly. It's highly unlikely this is a profile problem.

Nozzles are clean, at least my nozzle tests appear 100% correct. Also I'm not having problems printing with other profiles. Would formatting my harddrive change a printer setting such as the paper advancementment adjustment?

That woiuld likely be a huge waste of time. Re-run the alignment routine for your printer.

Its the printer, not the profile.

[attachment=4867:attachment]Sorry to confuse you about the reformatting of the hard drive. That is something I did a couple of months ago when I added ram and a new internal hard drive to my G5. I'll try the alignment routine as that is something I have not done since initially doing it when I bought the 7600 a few years ago. Still I don't understand how other profiles are printing fine while what used to be my best profile to use is now unusable.

Jonathon and Andrew, thanks for your input.

Andrew would a problem with the printer only manifest  itself with one profile while the others work fine?

Here is the problem, please excuse the terrible scan, colors are way off due to the poor scan but the streaking in the sky is what the profile is giving me. As said earlier I'm not having any problems using other profiles but I would like to go back to Bill's PLU 2 because it was the best I've used.undefined[attachment=4868:attachment]

All would work fine or not. But a profile can't self destruct, its either going to work or not even show up. Of course, it could be the file.

The fact that this statement is not holding true is what has me so perplexed. I would agree with you if I had not been experiencing this problem. The file is fine, it looks fine on the screen and prints fine  with other profiles. Also this problem is on any file I try to use the PLU 2 profile with.

[Peterretep]

I ran the alignment adjustment which was somewhat off. Using different profiles, the prints now are looking a little better, better blacks. So this was a good thing to do, unfortunatly it did not make any difference with the PLU 2 profile which I still want to use. Images are just as streaked as the example in the earlier post. Anyone with an idea as to why this one profile is not printing correctly please let me know.
Thanks,

When you say "streaking", are you referring to the noticeable horizontal banding in the sky, or something else?

Yes, I'm referring to all that looks wrong in the sky, including the upper right corner. Here is a scan of the sky as it should be. Again sorry for my scan, though it will show you difference .

Jonathon, thanks for the prompting to do the alignment. It was only done once a few years ago and was past due to do it again.[attachment=4885:attachment]

This might be a long shot but check whether you have all the latest PS updates as well as the latest Mac updates.  
A while back ( about a year or more ago) after I had downloaded some updates , I was getting just those bandings like in your sky. Instead of having a smooth transition in the color of the skin of the person in my image, there was a blocky banding of the tones, like in your sky.

Shortly after, PS issued another update that fixed it. Not sure what it was but it was  weird in that no one knew anything about it except I had gotten an email from one of my printing materials suppliers telling us about the problem.
I was only printing on the Enhanced matte paper so I don't know if it was on only that.
You might have reloaded an older version or something, who knows... stranger things have happened, eh?

[Jonathan Wienke]

Another thought would be to check to see if there are any printer firmware updates. Some of the internal settings for that paper type could be wrong. Also check print driver to see if it is most current version, if you haven't already done so...

[John Hollenberg]

A guy with a banding/smearing problem on his iPF5000 reported on the Canon iPF Wiki that he finally traced the problem to a head height setting of "High" instead of "Automatic".  I can't remember enough about the Epson printers to know if there could be a similar setting that could cause the kind of problems you are seeing.

The problem I'm having seems not to be with the profile at all. Instead it only occurs when printing at 2880dpi. I have what I think to be the latest Epson driver, 1.93 and have downloaded it and reinstalled it a couple of times but the problem at 2880 still persists. There is another driver for the 7600 ultrachrome ink on a Mac, driver version 3.09 thats compatible with OSX 10.5, mine is the latest 10.4. Unfortunately when I install this driver it does not install to either sheet or roll printers options, only installs to Epson 7600 printer which is very limiting. Using this driver does enable me to print at 2880 just fine but roll paper won't work. I've sent email to Epson about this and hopefully will have a response in a few days. Once I receive it I'll post it here.
Thanks to all who have tried to help.

The tech service rep at Epson says to print at 1440, that there is no improvement printing at 2880 other than using almost double the ink. 1440 looks very good but a few years ago I had tested it vs 2880 and 2880 was better, not much but better. The only other option to printing at 1440 would be to have an Epson service rep come to my place for a repair. 1440 sounds better
