Packaging products using cold foil hot stamping are more beautiful, elegant, noble and attractive. For printing companies, cold foil hot stamping represents additional value-added printing technology. For value-added printing of high-grade cold foil hot stamping, it is mainly used for: packaging, labels, commercial printing jobs, through cold hot stamping, on the printing unit through the metal image on-line overlay printing for product finishing. These images are separated from the carrier foil and transferred to the area printed with viscous ink, which eliminates the cost of expensive hot stamping plates and the hot stamping process, which are additional off-board production steps. Cold foil hot stamping can be processed online, which reduces the steps of the process chain, which means that orders can be delivered faster.
Compared with hot stamping, cold foil hot stamping can replicate and reproduce ultra-fine lines and elements. In packaging and printing, in the practice of using anti-counterfeiting elements together, its value has been confirmed. If cold stamping is not performed, this printing unit can still be used as a normal printing unit, and conversion requires only a few manual steps.
ROLAND InlineFoilerPrindor can be used to upgrade ROLAND 500 offset presses, and can also be retrofitted on ROLAND700 HiPrint series presses after 2004.
The quality of cold foil hot stamping ROLAND InlineFoilerPrindor cold stamping device can replicate the full field, the smallest details and line elements and mesh tone area. Compared with bronzing, because there is no heat effect, the whole field looks less dazzling. For the screen mesh with 60 lines / cm (150dpi) mesh tone, high-quality reproduction can be achieved. Depending on the metal foil and substrate used for sinking, high-quality reproduction can be achieved in the 20% to 80% of the dot range. Similarly, thin lines (0.25 pt), characters (4 pt) and details can be reproduced with clear edges. The cold stamped sheets can also be embossed during the second pass.
Consumables for cold foil stamping What materials are needed for cold stamping jobs? How are these materials different from traditional printing consumables? Under the system brand of printcom printing materials, Manroland provides ROLAND Inline-Foiler Prindor with a set of component materials that meet the system requirements for machine debugging. For technically perfect machine debugging. Of course, users can also use consumables from other manufacturers to operate at will.
Cold foil-cold foil has different color tones and surface characteristics (glossy, matte), and also has a holographic effect, and their basic structures are the same. The respective color representation comes from the color of the protective coating. The composition of the separation layer (silica gel layer) determines the nature of aluminum foil separation and the properties of overprinting with the respective ink system (conventional ink / UV ink).
Inks and coatings-Overprinting of metal foil with four-color printing inks will produce an impressive color space. For this reason, most jobs only use one kind of metal foil (silver) to make printing tools. Traditional applications can be performed on coated paper, uncoated paper, paperboard, absorbent printing materials, or structured printing materials. UV ink can be overprinted by traditional printing on coated paper. When overprinting on printed products with high ink coverage, a protective layer can be added.
Blanket-For cold foil finishing, a special blanket is required to replace the traditional blanket. In addition to allowing the metal foil to pass through at the meshing gap without deformation, the blanket also has an important contribution to the transmission of metallized ground, dots and details, thanks to its special surface properties.
Cold Foil Adhesive——The viscous ink for cold foil hot stamping with sheet-fed offset printing is an oil-based ink, its pigment content is reduced, and its viscosity is increased. This high viscosity is essential for the complete and perfect separation of the foil layer from the carrier foil layer. In the production process, the amount of viscous ink can be continuously adjusted to reduce quality fluctuations to a minimum. Ink density can be recorded as a density value and adjusted during the production process.
