Would this be an appropriate place to ask a question about densitometers? I am unable to get our xrite 408 to work with PS 4.0.

It is correctly attached and hyperterminal accepts input from it, but PS 4.0 will not. I get the same results on com1 or com2.

Also, do I have a prayer of getting the output from an hp2000 to match a 3000? Currently, the 2000 prints much darker on the same file.

HPs and Densitometer

If your 408 works in HyperTerminal, then it should work in Postershop with the same COM settings. If you are using NT, make sure the baud rate of the port in Control Panel is set to higher than the baud rate you will be talking to the device. For example, if you are talking to the device at 9600 baud, make sure the NT Control Panel setting is 19200 baud. If that doesn't work, you should call Onyx Tech Support and they can step you through some diagnostic proceedures.

As far as getting matching prints on a HP 2000 and 3000, make sure you are using ICC profiles in both cases. Also, you have to reprocess the job for the 2000 printer. If you just plug in the cable into the 2000 and click print with the 3000 processed data, you'll get the darker results you describe.

If you aren't using ICC profiles, then you'll need to do linearization calibration and use the same media model for both printers. The inks are similiar enough that you will get similiar results of the calibrations use the same media model (target densities).
