Hi Gordon
So lets just clarify
- you're using the same inks
- you've tried the same papers
- a nozzle check is ok
- a previously OK image now doesn't print ok
so
- do you have individual profiles for each different paper or do you rely on the printer profiles
- putting it another way, when you print is colour managemnt managed by printer or by Lightroom?
- for best results I have a separate profile for each papaer I use and then rather than "managed byprinter" I select "other" and chose the profile for that particular paper. As Chris says the strock profiles that ship with the printer only work well with the manufactures own papers, and even then better results can be achived with bespoke profiles.
- I'm assuming that you are printing from Lightroom? - this appears to be the onlything in your workflow thats changed
- has the upgarde to 1.4.1 changed any of your printer settings eg rendering intent?
It looks to me like a colour management problem somewhere in the workflow. Have you tried printing from photoshop (or equivalent that has colour management) rather than lightroom? Or reverting to the previous version of lightroom?
