Re: venetian blinds, Epson 1280
That's a pretty good general description of current printers. Except for the R1400, I have tested them all and am currently testing the 3800.
The R1800 definitely has not yet shown a problem with Venetian Blinds. The R2400 shows the least Venetian Blinds of all the other printers. I have not yet tested the 3800 for Venetian Blinds, but will do so this week.
you should have no problem with microbanding with any of the latest printers. The head allignment is very good on these printers and by doing a head allignment this problem is eliminated.
Here I'll differ with Sandy on this point.
With the R2400 and the 3800, the inks are indeed less dense than the older 2200 inks, but you have an option with these printers using ink configuration to increase the amount of ink laid down. I have no doubt that you can get enough density for any process using this feature. Unfortunately the R1800 does not have this feature. If you also use the new Pictorico Ultra OHP film, which will take an incredble load, you can get even more dense negatives using ink configuration. Note: this feature on the 3800 is actually located under "Paper Configuration".
While the 3800 definitely costs more than the R2400, if you figure in the additional amount of ink you get with the 80 ml cartridges, this reduces the cost differential dramatically.
With the R2400 and the 3800, the Advanced Black & WHite printing mode makes incredible black and white inkjet prints.
The 3800 is probably the smoothest printer I have tested so far.

If you want the large negative the 3800 is very smooth, but one is limited to a maximum negative DR of about 2.05, ok for most alternative processes but not quite high enough for albumen, salted paper, VDB, etc.
The R1800 also prints very smooth, but has the same limitation in terms of DR as the 3800. Also, the pigmented inks don't dry fast which makes it problematic for me since I u se the Ultrafine OHP instead of Pictorico.
The 1400 is also very smooth, but has low UV blocking with the colors, so the only way to get adequate density for alt printing is to desaturate the RGB file and print in color, which gives a neutral black tone negative with a maximum DR of about 1.80. This worked out perfect for me since with the Epson 2200 I had settled on a combination of Green and Blue that also gave a DR of 1.8, and this is also the DR to which I develop my in-camera negatives. And the dye inks of the 1400 dry very fast so pizza wheel marks is not a problem. And the 1400 is a good candidate for making digital negatives for silver printing because the tones are so smooth.
The pigment ink set of the 2400 gives more UV blocking density than any of the other current Epson printers, but it too is subject to the Venetian blind disease. In fact, according to Mark Nelson, the only printer that is not subject to Venetian blinds is the R1800. We can not say yet about the 3800 and 1400 because this disease usually strikes when the printer has some age on it.
In any event, the Venetian blind problem is my biggest concern. I have a perfectly wonderful Epson 2200 that does everything I want from it and can print negatives of the right DR for any alternative process, but it has a very mile case of Venetian blind disease that shows up with scenes where there is a lot of broad areas of upper mid-tones and highlights.
You can try running the head alignment, as others have suggested, but this may not cure the problem if the printer has some age on it. But by all means give it a try.

Sandy... I know you've been testing several printers lately, and I've
been reading your comments with interest. I'm new though, to digital
negatives, so some of it is flying over my head.... some of it is
beginning to sink in. I'm making positives on pictorico ohp, for
making polymer gravures... I'd be interested in knowing which printer
you'd recommend at this point. I would need 13" wide capability.
Thanks for all the testing and reporting you do on this stuff.

Based on my experience with this problem on several Epson printers,
IMHO the only real and true fix is EBAY.
