hi,

depending on what type of RIP you are using, you could create a workflow and add a "dot gain" curve (10-25% etc) or add a curve to a workflow you already have.

to verify, place a grayscale chart on the plate that you can read with a plate densitometer. or create one yourself.
boxes of 10-25-50-75-100%.

if the curve has been applied, in theory the grayscale would read higher according to what curve you used.

hope this helps,
cesar

If I understand you correctly, you could build different dot gain compensation plate curves and make them available to you when RIPping different jobs. You would have to decide on whether to target different print characteristics or to align all incoming files to a single print characteristic. You would also need to make sure you understand why your customers are supplying such a variety in their files.

Having different dot gain compensation curves for different paper types is not unusual. Having different dot gain compensation curves for different incoming files is unusual.
