1440 dpi, 2880 dpi or????? for QUALITY PRINTS

[Tom Swaman]

I hope this thread has broad appeal and is not just of interest to a few. My Epson printer gives me the option to print at 1440dpi, high speed(both directions) or low speed(one direction) or at 2880dpi at high speed or at low speed. My questions for your comments are:

.....1) When do you print at 1440dpi and when do you print at 2880dpi?

.....2) When do you print at highspeed and when do you print at low speed?

.....3) Is printing at 2880dpi just a waste of ink or are there better quality characteristics to the print? What better print characteristics result from printing at 2880dpi?

.....4) Is printing at low speed just a waste of time or are there better quality characteristics to the print? What better print characteristics result from printing at low speed?

Thanks,
Tom

If you have a print printed at 1440 next to one printed at 2880 and you get your nose right up to it, you'll see differences. If you look at a 1440 print by itself, it will look just fine. I pretty much always print at 1440 on my 4000 just because it's faster.

If your heads are properly aligned, there's no difference between high speed and low speed. It's easier to have properly aligned heads if the printer does it for you. My 4000 does it and the 3800 does, I think. I don't know about the 13" and smaller printers.

Tom,

What you say is what I do. I just wanted two super 16" X 20" prints and I did print these at 2880dpi and they were incredible. I perceive that I see a very small quality difference relative to 1440 dpi printing, but then I did this on Epson Premium Luster so the added ink is on the surface and visible.

I have automatically aligning heads and I have not experienced any significant head misalignment upon testing. By the same token, I have been printing at slow speed.

Thanks for your feedback,
Tom

2880dpi is enough for Quality Prints

Perspexart,

I apologize, but I am uncertain that I understand your post. Are you saying that 1440 dpi is not sufficient to generate a quality print and 2880 dpi is enough to generate a quality print? What print ink resolution do you use?

Thanks for the clarification?

Tom
