4. Screen Design<\/h2>\n

\n
• Film<\/strong>: 40mm screen with 50% Open Area<\/strong>.<\/li>\n
• Rigid<\/strong>: 40mm screen with 35% Open Area<\/strong> (stronger web thickness).<\/li>\n
• Failure<\/strong>: Running lumps on a film screen will bend or break the screen due to lack of structural rigidity.<\/li>\n<\/ul>\n

  Conclusion<\/h2>\n

  Buying two specialized machines (one for film, one for rigid) often has a lower Total Cost of Ownership (TCO) than buying one “Universal” machine that runs at 60% efficiency and requires constant maintenance.<\/p>\n
