Epson 2400: question about creating BW image on transparency at 720 DPI

Epson 2400: question about creating BW image on transparency at 720 DPI

2007-07-10 by David

I want to print an image on transparency film using my Epson 2400, but 
I only want printer output to be 720 DPI, which is fairly low 
resolution for this printer--but I still want a fairly good quality 
image with good blacks and no banding. 

Advanced BW mode only prints at much higher resolution. And I've tried 
selecting the "Fine" quality setting (which goes with the plain paper 
media and is supposed to be 720 DPI), but the print was poor quality, 
the BW was made up of colors which you could see, and the image had 
banding. 

I'm left with two other options I've though of: find the correct media 
to use "Image with Text" quality setting (or whatever its called, but 
that's close) which is also 720 DPI, or try using the Quadtone RIP, 
which allows me more choice in selecting output resolution. 

Any other suggestions or thoughs on these methods.

Best, David.

What is the reason for sticking to 720dpi?

If one is trying to define dots, thats the max rez at which actual image dots 
get used, instead of dithered... so printing your own plates, and similar 
functions, requires working at 720dpi...

Ah yes, the question . . . . which I've gotten before. 

I'm using the transparencies to make photopolymer plates for intaglio 
printing on an etching press. There needs to be "grain" in the image, 
which will equate to "bite" on the plate, which holds the ink in the 
recesses of the plate. At higher resolutions you loose the grain and 
can't create a good plate for printing. Another option may be to 
add "film grain" to the image before, but I'm trying to keep it simple, 
if you can believe that! 

Best, David.

Yes, C. David, that's exactly what I'm trying to do.

Many thanks for the answer. Best of luck with your project, it sounds
interesting but well beyond me!

Then I would let the quality of the printer shine and run test on a variety
of grain added to your file. You'll get the advantages of quality, no
banding color or lack thereof, and the apparent grain or dot pattern that
you need. There may also be some help on the Alt Photo Process group, APUG
or the Alternative Process web site. 

 

I haven't looked to add more noise as I mostly go smooth for platinum and
Chrysotypes.

Yes, its one of the options I'm looking at. I have a Photoshop plug-in
that allows me to add grain with control over the size. The only thing
is that the grain is made up of gray, black and white pixels, and I
need  more contrast and blacks and whites. So I'll try adding unsharp
mask and test the outcome. 

Best, David.
