Problem with black

[adamwooo]

I have the problem with black. The black colour is not black like iluminated (exposed from bulb) paper. I've tried to change modulators positions, but effect is the same. Have You got any idea what is wrong ? Machine is noritsu 3300

I would like to add that the black colour of daily setup , the blackest patch is ok, but on the foto is lighter , is dark gray.

1) does light-fogged paper black enough after processing ?

2) check actual developer temperature in the CD tank

2) Try change the developer in the processing tank.  Before this, rinse the tank throw away old chemical filter

good luck

I've changed the developer, overexposed paper on sun has goog black, on daily setup is good black, on picture not. Yes light-fogged has good black, so temperature CD tank is good.

Try cleaning the calibration plate for the colorimeter with a soft cloth and a mild neutral PH soap.

Can you tell me the what the step 22 (last step) readings are for the daily setup?

Maybe take a screen shot (ALT Print Screen, open Paint and click Edit, then paste) attach to this post.

Here is my daily setup table.

You must change calibration plate.

[Dave S]

The last step readings are too high, they should not be much higher than 2.55 your readings are almost 4.00!

Try cleaning the calibration plate and see if the readings go lower, if they don't you will need to replace the calibration plate.

is it possible that the reason is different calibration.ini file ? I had a problem with densitometer, technican send me the file for calibration plate form different machine to resolve this problem. So i changed it. After cheanging developer the problem with densitometer has gone. But is with black. Tommorow i will try to load the original file and clean calibration plate.

I think that is wrong calibration plate.dat. Can anybody send me noritsu 3300 plate.dat whih is on service disk ? 

My email : adamgsx@gmail.com

[Dave S]

The file you need is plate.dat, this comes on a floppy disk labelled "Calibration Plate Data" with the serial number of your calibration plate.

The plate.dat file is unique to each calibration plate, so you cannot use the data from a different calibration plate and expect it to calibrate properly.

The chances are that your calibration plate is worn out anyway, so I think ordering a new one will be the best solution.
The new calibration plate will come with a floppy disk with the updated data on it.

The part number for the new metal calibration plate is Z028442-01

Agree here.

Calibration plate has unique FD with unique data and it cannot be used with other plate.
So the purchase of new Calibration Plate is the only way out as kodak-service wrote above.

[adamwooo]

I've written Noritsu, they sent me plate.dat file exactly for my plate number.

the calibration plate and the disk must match, i think #21 result is not right
