pantograph issues

[Richysny]

We have been printing Pantograph screends for years with no problem. We recently changes from a Positive thermal plate to a negitive thermal plate and it has affected our Patographs. We have thousands of files that have the BMP pantograph screen in them. Is there a way to adjust the screening over all rather than opening and reworking every file? this is on a Magnus CTP device running Printergy.

You need to create a dot gain compensation curve that gets applied to the negative plate that results in the same tones on press that you were getting with your positive plates. That's a pretty straight forward process.
