A METHOD FOR IMPARTING DIFFERENT VISUALLY DETECTABLE FEATURES TO A PLURALITY OF ITEMS, AND A PACKAGE COMPRISING ITEMS EACH HAVING A DIFFERENT VISUALLY DETECTABLE FEATURE

摘要

The present invention provides a method of continuously imparting different visually detectable features to a plurality of items using a printing and/or embossing roll. The circumference of the roll must differ from the whole number of the item lengths, i.e. the length of one item multiplied by an integer. In a production series the number of items each having a different visually detectable feature provided before said visually detectable features repeat themselves is greater than the number of items imparted after one full turn of the roll. The present invention also relates to a package comprising a plurality of items each having a visually detectable feature, wherein said visually detectable feature of each of said items is different from the visually detectable features of all other items within said package, such that a first item comprises a first visually detectable feature comprising at least a portion of a first visually detectable pattern element, and a second item comprises a second visually detectable feature comprising at least a portion of said first visually detectable pattern element, wherein said first and second visually detectable features are different.
