What is Web Growth?
Web Growth is the deformation (stretch) of the paper as it is printed on the various color units on a web press. The physical deformation occurs as the paper absorbs ink and water, and is accelerated with pressure and tension.
Factors contributing to web growth include: type of press, press configuration, paper stock, humidity, ink coverage and conditions of the blanket. Heaters may cause paper to shrink on press.
Using marks and profiles to compensate for Web Growth
Web Growth Compensation profiles allow printers to compensate for press mis-registration due to distortion of the printed media. This most frequently occurs on web presses where the paper may expand or shrink slightly after running through a specific press-station, causing subsequent colors to misalign. This also occurs less frequently with higher-grade paper.
The WebGrowth Profiles resource allows you to import, export or delete ANSI WebGrowth Profiles (*.wgc files). You can link a web growth profile with a paper type in your Press settings.
You can also create your own WebGrowth profiles for any combination of press, ink, stock, etc. and special marks can be placed on the Press Sheet to measure and monitor web growth. The WebGrowth mark is a special file mark (.pdf) that needs to be placed on the Press Sheets.
NOTE: Deferring this image compensation to the film/plate phase of the workflow allows the user to use a regular pre-press workflow without compromising proofing and preview job approval features.
