Some of the world's key manufacturers of magazines, catalogs and B2B brochures are currently using variable Muller Martini trimming technology and capitalizing on the clearly measurable advantages it offers. Variable trimming technology has been the hot topic in the graphics industry for a while now, but there was some concern over potential loss of production speed. However, users of the new three-knife trimmer 304 are achieving significantly higher net output at higher cycle times.

The variable front-trim technology enables finishers to expand their customer base by highlighting the advantages of parallel production of numerous titles and format sizes – that is, a single process with parallel mailing – to both existing and potential customers. In-line processing of numerous titles with varying format sizes lowers production costs, as the expenditure on transport, storage and personnel is reduced.

The three-knife trimmer 304 with automatic front-trim control is available with the high-performance Muller Martini Tempo 22 saddle stitcher and can be retrofitted to existing Tempo lines.
