Funny how little has changed in the laser world since I wrote about their ability to make digital negatives back ten years ago.
Laser printers are by and large used in the business world because of their speed and lower per-print costs when compared to inkjet printers. But the business world rarely has need for the quality that photographers demand. We use an Okidata laser with 1200x600 resolution and it does a great job of printing double-sided handouts. The color illustrations and photos look "good." Some photographer friends even use this type of printer to produce limited edition calenders they send out at Xmas. But these same photographers would never consider using the laser for final fine print output.
Now if you're ma
king negs for one of the "forgiving" processes (I've been scolded in
the past for suggesting that gum doesn't have as faithful reproduction characteristics as some other processes), then you may be perfectly happy with laser negs. But, and this is my opinion, if you are contact printing on something like silver gelatin or a fine-grain pt/pd paper, you're not going to like the results unless a certain gritty stylization is part of the plot.
Mark Nelson and I are both fond of the Epson 3800 for making inkjet negs. As a matter of fact, my 3800 printer is waiting for me at Photographers' Formulary for next week's class. I ship it ahead because it's good when students can use a current printer that makes great negs. Having said that, my 3800 has a seriously f***ed print head. The magenta nozzle pattern has as many gaps as it does pattern. But I use Epson's Advanced Black and White mode to make negs and the magenta and cyan inks aren't even used in that mode so this printer, though it stinks for "normal" inkjet printing, st
ill makes a perfect negative. And yes, I tried all the Windex-on-foam-pad-let-sit-overnight and rub-printhead-back-and-forth-on-Windex-soaked-paper-towel tricks to no avail.
The 3800 is long in the tooth (over 2.5 years since it's introduction) but is a real workhorse. Anyway, inkjets are way better than lasers.
Hope this helps,
Dan
