Images from digital camera print as a 8 bit image

Tue Jan 20, 2004 10:52 am

The images from a Minolta 7hi come out looking like 8 bit image on the printer.
On screen they look fine. They are saved as 2560 extra fine in the sRGB space.
I looked under properties and they show as a regular jpeg.
It was my understanding that this camera DOESN'T need that Q Image software since Minolta went back to the standard sRGB color space.
The program I use (Thumbs Plus) and have been using for years works with any other image I have printed, same goes for the printer (HP 932). Only these pics come out very grainy!
The other digiutal camera I have (a cheap 1.3MP point and shoot) looks fine (1024x768) and the film scanner (HP S20) comes out fine.

Again all with the same program and printer AND printer settings!

Any ideas??

Win 2k w/sp4 if that matters.

Is your program changing the size ratio to match the print? For example, it may look fine on the screen becuase its 1024x768 but your paper isnt. Perpahs the printer is changing that ratio in the print. That's all I can think of.

Do you have a program like photoshop or any other that you could try to print through. Also try printing different sizes.

It sounds like the printerdriver is doing some resizing that isnt healthy.

Typically the program massages the data before sending it to the printer. Check printer settings, driver, etc. I would be willing to bet if you printed from another program, or through a different driver you will get drastically different results. For example printing an image through Word comes out quite a bit different than that from Photoshop, and again different through Picture Publisher. They all have their "optimizations" to try and improve print quality.

I did try another program and the same thing.
What I did try which I NEVER used or changed in the 2+ years I have had this printer is the selection; 2400x1200/PhotoEt. I changed it to 2400x1200 and it seemed to improve the image.
I don't know what is going on. I have printed photos before and they have come out fine without changing anything other than the paper selection.
Again I'n NOT talking about image noise! Just a VERY course image as a M$ splash screen looks.

Since no one has any input on this; it turned out to be the cartridge!
Never had that happen before. I treid anothe refilled cartridge and it was fine. I cleaned the 'bad' one but it still prints poorly (photo only). Regular drawings and web pages print ok (non critical material).
