He won’t know what densities he should be running to, as this will depend on stock and ink being used.
Initially you need to check that your plates are linear (50%=50%) and if they don’t then you need to input the values you have and generate a compensation curve to bring them (ideally) to within 1% of desired dot values.
Then output a suitable test form and get your press minder to run a range of ink weights from high to low (within reason) from one side of the sheet to the other. You can then go through and check your solid LAB values to find the closest match to your standard (I’m assuming G7). Once you have found the closest LABs you can then take density readings from these patches and there are your ideal ink weights for that stock/ink combination.
Next up is to run your test form again but now you can run to your new ink weights all the way across the sheet.
From these sheets you read your presses natural got gain values and make a separate compensation curve for use with those inks & stock. Obviously you need to reference the standard again in order to know what your desired TVI values should be (for Coated I’m guessing around 14-17% @ 50%).
Hope that helps
