Linerless price reduction continuous label, applying method and printing method of linerless price reduction continuous label

A method of applying a linerless continuous label, wherein the linerless continuous label comprises:

• a label base member having a front side surface and a back side and having lateral edge end portions;
• an adhesive material layer on the back side of the label base member;
• a heat-sensitive color forming layer on the front side surface of the label base member;
• a release material layer on an upper layer of the heat-sensitive color forming layer;
• an indication region configured for indicating information and a bar-code cover-up region capable of covering-up a previously present bar-code, the regions being separable by a region separation line;
• the information indication region and the bar-code cover-up region are separably connected to define a unit label of a linerless label by a unit joining line;
• the method of applying the linerless continuous label including:
• configuring the region separation line by forming a first line of perforation across the linerless label between lateral edge end portions, the first line of perforation including first notches each formed widthwise of the label inwardly from a respective lateral edge end portion of the label base member, and
• configuring the unit joining line by a forming a second line of perforation across the linerless label between lateral edge end portions and parallel to the first line of perforation, the second line of perforation including second notches each formed widthwise inwardly from a respective lateral edge end portion of the label base member;
• forming each second notch longer than a first notch widthwise of the linerless label;
• separating the bar-code cover-up region from the price reduction indication region at the region separation line of the linerless continuous label;
• and
• applying the bar-code cover-up region such that it is overlaying on the bar-code relating to the information of the original price.

• forming the second notch longer than the first notch widthwise across the label;
• printing the information on the indication region;
• and
• printing the bar-code relating to the information on the bar-code cover-up region.
