Define reusable scaling sets that compensate for stretch at each of the ink units on particular web presses. When printing jobs, you can select and apply or edit a scaling set as needed.
The amount by which the paper stretches varies for each ink unit, depending on the water and ink that the paper absorbs, and the tension that is applied to the paper as it runs through each ink unit.
A print shop typically knows what percentage of stretch occurs at each unit. If they don't know the exact percentages, they can easily run a test job through the press and measure the stretch percentage for each unit.
To define web-growth compensation scaling sets, you must have an advanced understanding of web-press concepts and behaviors. To manage the scaling sets, you can:
- Add, edit, and store reusable scaling sets as needed
- Edit an existing scaling set for a specific job
- Duplicate and edit an existing set to create a new set
You can optionally set up a central folder for compensation scaling sets, and set the path on the Folders tab in the Preferences dialog box at each installation that uses this folder.
Note: Changes that a user makes at one installation are not reflected at another installation until the other installation's Web Growth Compensation Sets window is closed and reopened.
