Hi!
I discovered that the built in profiles that Epson provides work pretty
darned well....
I see... Happy discovering ;-)...
A question to you... Recently I bumped into odd kind of problem. I
submitted b/w RGB JPGs (30x40 cm at 300 dpi) for print to a supposedly pro
lab in Tel Aviv... They complained that it should've been 400 dpi... So
they said they'd up-res for me... I agreed somewhat reluctantly.
It's important to know what the native resolution of the printer is.
Fuji's native resolution is 300dpi, Noritsu is 320.
Not sure about other makers machinery.
Most of them have pretty good interpoation algorithms built in. Noritsu does
a beautiful job of up ressing smallish files.
Then the prints came out bluish. Reluctantly they agreed that this was
their fault... So I asked them what could I do.. And they told me this:
they have two machines (one I know to be Fuji Frontier, the other is
unknown to me)... The bigger one is somewhat more stupid... The smaller
one (print size up to 25x38 cm) can be forced to proper black and white...
So I had to redo my files and they came out smaller yet beautifully toned.
A question - am I going to have to live in smaller print size world
forever? They do publish some kind of color profile on their web site...
Unfortunately all the instructions are in Hebrew and beyond my ability to
read...
If they are printing to photographic paper, then the only profile they will
really understand is sRGB.
For stuff I am doing at my lab, I set the pixel count to 320dpi, and then
set the print size to just slightly larger than what I want. The printer
seems to need about 1.4% waste space, for reasons unbeknownst to me. I then
convert the file to 8bit sRGB and save it as a large jpeg for printing.
I can either upload it straight from my desktop to my lab, or carry the
files in on a CD of camera card for printing.
