Dear sirs

When looking close to my pictures through a loop i can see some lines in the prints coming out af a DKS1550 machine, so i go into SU and choose piezo calculation press print and out comes 5 picture made on the 20cm paper, my problem is that i don't know what picture i should scan in for calculation, the all look the same to me.

Do you have some solution to find out what print to choose for scanning.

Hi

Before you do the Piezo calculation you should run a PRNU print to see if there are any dead pixels and that you have uniformity across the grey scale.

The help button will guide you through this process, It is a little convaluted because of the translation from French to English, but easy enough to work out.

Whem you have uniformity, then check the Piezo print.

You are looking for 3 prints that look the same ( the lines at 90 deg on the sides of the dotted square).

Again read the help file.

Good luck
