Tweens – Looks Matter for Print Products

Monday 12. October 2015 - Muller Martini's TWE¦?NMC option enables bookbinderies to produce even more attractive books and brochures.

Advertising messages, coupon booklets and maps in guide books can be stitched in a book block as smaller folded signatures using the Muller Martini Ventura MC book sewing machine. Tweens offer considerable value added. They lend themselves to high-quality inlays in art books and catalogs, or to conveying knowledge in textbooks in an interesting way. The ability to stitch in signatures with different fold types opens up new horizons. The Berlin-based bookbindery Stein + Lehmann is convinced of the potential of tween products in the fields of art, culture and advertising, in particular. Its two business managers, Thomas Lehmann and Detlef Brall, have observed that their customers attach increasing importance to high-quality and stylish products. “Looks matter for print products,” says Lehmann, explaining why he recommends the new and attractive tween option to customers.

Yet, since there are limits to how much customers will pay for thread-sewn products, highly automated and cost-effective production is essential at Stein + Lehmann. That is precisely why the Berlin-based company has invested in a second Ventura MC from Muller Martini, this time featuring the tween option, seven years after purchasing a Ventura MC and three years after its first Ventura MC. The quick processing times of the new Ventura MC are of particular benefit to the bookbindery for short runs, which are not uncommon for large illustrated books in the art field. The tweens do not present an obstacle to fast processing – the Motion Control drive design enables fully automated processing, since the finger chain adjusts automatically to the different sizes. An additional servo drive in the sewing saddle makes it possible for the tweens to vary both in length and width and to be individually positioned in the book block.
