24.01 Since supermarkets became the main seller of wines for mass consumption all over the world, the same rules as for other consumer goods became necessary for this alcoholic drink, forcing “to stand out on the shop shelf from a crowd of competing products”. The main source of attracting the attention of the buyer remains a simple wine label.
10.06 Print quality, high speed, a large selection of printed self-adhesive materials, the use of different types of inks, including UV, installation in the line of additional finishing equipment for printing in one run - makes flexography one of the most effective ways to print labels. This method is most beneficial in the production of large and medium runs.
09.06 The history of creation and production of self-adhesive labels starts at the beginning of 30s of the XX century. The formation and development of the product market took place at a swift rate, so manufacturers fought for each customer. The label has received much attention, but manual sticking was a labor-intensive and low-productivity affair.
20.02 This topic today attracts many, but not everyone is familiar with the technology of printing and further operations with such labels. We offer you a selection of articles devoted to this topical issue.
29.12 The simplest compositional system consists only of a monomer and a photoinitiator. A photoinitiator containing the so-called chromophore group absorbs a quantum of radiation of a certain wave length, goes into an excited condition and dissociates into two excited free radicals, whose activity depends on their structure (this is the initiation stage).
06.10 Innovative technologies in the field of flexographic form processes are actively developing. Most of them are connected with the improvement of existing technologies for the manufacture of printed forms by solving the problems arising in the production process. The capabilities of one form technology or another are evaluated by the method of controlling the characteristics of printed forms. It is known that instrumental control is an integral part of the process of getting high-quality printed images, however, such control of forms is associated with a number of difficulties. They often do not allow to make an accurate and reliable value of flexographic forms.
20.08 UV light has been used for the polymerization of inks and coatings for many years. The sources most commonly used for this purpose are UV lamps of medium-pressure. The spectrum of the lamps is adjusted to the characteristics of the used photoinitiators of inks and coatings.
07.07 The joint project “REVO - Digital revolution in flexography” is based on the joint work of the largest manufacturers for the flexographic industry Adare, DuPont, Apex, Esko, Nuova Gidue, UPM Raflatac, Flint Group, united by a single idea: to bring the classic flexographic technology to a digital standard. Reducing costs, increasing efficiency, stability - these are the main goals of the revolutionary REVO project, and this will definitely further strengthen the position of flexography by deciding the questions of the printing of short runs, ensuring the necessary flexibility and quality of production.
09.06 In one form or another, the technology of exposure of High Definition Flexo (HD Flexo) is used in more than 30% of all digital laser recording devices of forms (flexo-CtP) all over the world. During three and a half years after the putting on the market, the technology underwent a number of changes, which allowed to expand significantly the tone range and that way to enhance the visual effect of the packaging. At the same time, the simplicity of the process was kept and even the number of manual operations was reduced. It was an interesting combination of discoveries when studying the properties of raster dots and form technologies.
