recently our hard drive crashed ,and we had to purchase a new one .most programmes are re installed ,and so is our printer,but though we've calibrated everything the screen and our printer don't match colourwise at all ,and our prints are no longer competition quality.

we're begining to think we must have missed a vital piece of software ,or a magazine article which we used to fine tune last time .

You say you calibrated your Monitor and Printer, you then suggest you did this previously by using a magazine article.

Start again and unless you have an Hardware Calibration tool (Spyder) then download

http://www.hex2bit.com/products/product_mcw.asp (Calibration Wizard)

and 

http://www.normankoren.com/makingfineprints1A.html (Gamma Calibration)

Now initially use the printer setting "Let Printer Determine Colours" 

This will get you pretty close to being accurate

And as AJ says Make sure you have the correct printer drivers 

One other pointer - paper surface, type and quality will shift colour also... Pro inkjet papers often have advice cards to suggest fine tuning +/- output of ink types that you can set up for your printer.

Of course if things are drastically different following the HD crash, then it's down to something along the setup being different than before. It may be worth uninstalling printer, starting from scratch using all the print software and colour calibration software that you have to get things right.

Colour is one of the fine arts of photography, and it's damn hard to get it exactly as you want it - be that traditional or digital print outs. Make sure that you're observing under good sunlight also...tricky at this time of year!

All the best...

Many thanks for your advice,it was really appreciated .

Dave (hubs)has had time to concentrate over the christmas break,the printer has been uninstalled , everything has been checked and re installed ,and we're finally happy with the results .

Happy New year and thanks again
