[alt-photo] Re: Epson 2400 ink density problems

Hi Mark,

Yes, I have never seen a document that is in Adobe 1998 converted to sRGB on the fly before so the computer must need an upgrade or I just tell students to not assume anything.

Another biggie with a gang printer like this is when a neg comes out namby pamby and I ask if the heads of the printer were checked or the ink supply checked and I get the answer, "Yes they were just checked" but when you have 18 students printing out with similar colorized negs, nozzles need to be checked frequently, not just daily.

When I first saw the colorized neg I thought it wouldn't work but it stands to reason that the tonal relationships within the image would change.  E.g. the magenta tree wouldn't hold as much light back as the typical red/orange tree would in BW.  So the picture looks "normal" in actuality because you still see a tree and a sidewalk and a river....

> It is always amazing...... you are right, every time you teach, something new crops up.  But, that's how we learn!  You might check to see if the color settings in Photoshop have all those little check marks checked that warn you of mismatches in color profiles.  Students often get sRGB files off of digital cameras and forget to convert—especially if Photoshop is not warning them.  Also, I had a combination of either CS2 or CS3 and one of the Mac operating systems for a while magically change my color space in Photoshop from Adobe 1998 to sRGB.  I never figured out what caused it, but one of the upgrades "fixed" the problem.
