December 08 Photo discolorationA 2 years ago I have bought HP PhotoSmart D7163 ink-printer. As a testpage I printed photo of blooming cherry-tree on A4 sheet of photo paper and stick it at kitchen. Part of photo was closed by magnet. Few month ago I took out magnet and noticed the contrast between 2 parts of photo - the closed one looks essentially more "fresh" as open part. So, I decided to make an experiment.
At October 14, 2008 I have printed 2 copies of the same photo and put one to the album while second stick to wall in a hall. Then, aproximately once per 10 days I took both copies and scanned (600dpi with HP ScanJet G3010). Essential discoloration can be noticed after 40 days! That allows to make conclusion that ink-printers is bad choise for digital photography, even for home usage.
You can see results here (in my space at "Ink-photo discoloration" album) or here also:
Photos at Step 2 (10 days old)
 Photos at Step 5 (50 days old)
 Note: all photos were printed using original HP supplies on HP Advanced Photo Paper.
And that is reason to be sad about digital photo processing by HP. :-( I would like to compare results with Espon or Canon printouts, if you have such results please provide me with information.
PS. Here is another example - 10 month after print:
As you can see photo became worser and worser. So, when I'm sending photo to parents or friends and they stick it to the wall, freezer or mirror... there is quite a big chance that only within a 1 year they will not be able to recognize who is on photo. :-( PPS. And finally, after 1 year is passed after a experiment started I have made a new printout and now compared it against the photo stored in album. Photo marked as "O2" is a new printout, photo marked as "O" is old. As you can see - we can notice the small difference in colors - seems red color became a bit weaker on the old photo. So, even in the photoalbum photo is fading. Of course fading of photo in album is essentially less then fading of photo stored on open air but for sure - it is fading. |
