Running Rampage 10.5 and would like to know the steps on setting up
curves. We added a new press and our standard linear profile is not
working. Thanks for the help.
Did you select a media linearization when you ran your linear plate? I would think that you would want to choose a media linearization when plotting to plate along with your Actual and Desired Profile, if that's what you did for your linearized plate.
I have heard of some people though, preferring to run their test plate WITHOUT it being linearized and then letting Rampage adjust accordingly from there.
Makes perfect sense to me gordo. Less is better. We currently run the two curve set-up but I would like to change it to one. The next time we do a footprint of our press, it will be without plate linearization.
I have read a lot of posts regarding linear or non-linear plates. Here's what my 40+ years of experience has taught me. Linearize the plate FIRST, no, you don't have to, BUT, if you do, then #1-we are sure that the plate is printing a 1-2-3-4% dot and #2-we "know" what a 1-2-3-4% dot area should be on press.
#3-when management changes plates cause they got a 'better deal' - all you need to do is linearize the "new" plate, all your curves still work!
Also- Creo, and later Kodak use to 'over expose' their positive plates, to make sure the background came off easily to prevent tinting, on press. Many shops I visited a 50% measured 44-46%.
