d-lab.2, d-lab.2plus, netlab.2plus: OperationTestsProcedure for paper calibration to new maximum densities1. Measure the obtained maximum densities (Dactred, Dactgreen, Dactblue) on a currentPBL print on an external densitometer. Measure the field with the highest density onthe PBL print (fully right).2. Calculate the differences with respect to the nominal external maximal densities(Dnomred, Dnomgreen, Dnomblue):∆Red = (Dnomred – Dactred)∆Green = (Dnomgreen – Dactgreen)∆Blue = (Dnomblue – Dactblue)3. Read the old Dmax values in the screen Print PBL (function with laser pointactivated) and add the calculated differences to these values:Dmaxred_new = Dmaxred_old + ∆RedDmaxgreen_newDmaxblue_new= Dmaxgreen_old + ∆Green= Dmaxblue_old + ∆BlueEnter the new Dmax values and press Start to initiate a new PBL with laser point.4. Measure the obtained maximum densities on the first PBL print (i.e. the third test printcoming out of the machine) in the external densitometer (see 1).5. Repeat the steps 2. to 4. until the required maximum densities can be obtained. Byexperience we know this may take several cycles.5AgfaPhoto 2005-05-01 / PN 04092_01 5-17
