With carbon footprints, resource consumption and costs under increasing scrutiny, the paper savings achievable with Goss Sunday presses are re-emerging as an important environmental as well as economic advantage for printers.
Sunday web press systems have saved 1.5 billion pounds of paper equating to 2.2 million trees since 1993 – the result of shorter cut-offs made possible by their cylindrical "gapless" blankets and pinless folders. Gapless Sunday press blankets increase the printable area on the cylinder by eliminating the gaps required to secure flat blankets. This allows printers to select a Sunday press with a cut-off that is .5 inches or 10 millimeters shorter than the cut-off of a gapped press, cutting paper consumption by 1.5 to 2 percent per cylinder revolution while still producing the same finished product sizes.
Pinless folding preserves the advantages of the added printable area by eliminating pin trim requirements.
The 2.2 million trees saved as a result of the shorter-cut-off Sunday presses represent approximately 4,300 acres of forest. Environmental advantages are compounded by the reduction in energy required to harvest, transport and process trees and paper. The paper savings calculations are based on conservative estimates of typical production schedules for the more than 300 Sunday presses installed worldwide. Industry-accepted averages were used for calculating trees consumed in paper production.
Since being introduced in 1993, Sunday presses have been installed in 23 countries. The innovative gapless blanket technology was developed to eliminate vibrations that occur when opposing blanket gaps meet, allowing higher print quality at higher speeds on wider webs. The press platform has been continuously expanded and enhanced and now includes Sunday 2000, Sunday 3000, Sunday 4000 and Sunday 5000 models for virtually all printing applications, with formats ranging from 16 to 96 magazine pages per impression.
