Self-adhesive labels, their production and use
View Patent ↗A label comprising at least one first print substrate layer printed on one side with a self-adhesive composition which if desired is lined with a release paper or a release film, where on the first print substrate layer first, on the side directed toward the adhesive a printing ink has been printed, so that there is a printing ink between print substrate layer and adhesive, and secondly, on the side opposite the adhesive surface, a further printing ink has been printed, so that there is a further printing ink on the top face of the print substrate layer.
1. A process for producing a label, the process comprising the steps of:
unrolling a first reel with a carrier material from a first of two unwinders,
unrolling a second reel with a print substrate web from a second of the two unwinders,
printing on the print substrate web by a first printing method selected from the group consisting of offset, letterpress, flexographic and screen printing,
coating a release-coated side of the carrier material with a self-adhesive layer,
laminating the carrier web and the print substrate web to one another so that the self-adhesive layer covers the printing on the print substrate web,
turning the laminated web,
printing on a top face of the print substrate web by a second printing method different from said first printing method, wherein said second printing method is selected from the group consisting of offset, letterpress, flexographic and gravure printing,
optionally, die-cutting the laminated web to form individual labels, and
optionally, rolling up the label which is in the form of the laminated web,
wherein said resultant label comprises at least one print substrate layer having a first and opposing second side with a self-adhesive layer coated on the first side, the self-adhesive layer optionally being lined with a release paper or a release film on its outer surface, wherein the first print substrate layer has
a first printing ink printed on the first side of the print substrate layer so that the first printing ink is between the print substrate layer and the self-adhesive layer, and
a second printing ink printed on the second side, so that the second printing ink forms a top face of the opposing print substrate layer second side.
