Uncoated papers and boards with light-fast colours.

Sirio Color is ideal for packaging, coordinated graphic materials, applications covers, inserts and deluxe brochures. Best performances are found when very light-fast colours are required. Can be used without problems with the main printing systems: letterpress, offset, blind embossing, thermography and screen printing.

Ideal for use with oxidative drying inks due to the macro-porous surface of the paper.

For this black colour, take care when using hot foil stamping reproductions, in specific hygrometric conditions, as using unsuitable foils can cause problems like oxidation or speckled printing, especially using colors like gold, silver or metallic. It is recommended to consult with your foil providers. In order to give total solution to this problem, it is necessary to isolate the film for hot stamping printing from the paper: it can be done either with a plastic coated surface, a double hot stamping printing (making sure to use a white or transparent film before the printing metal band), or with a printing water-based or solvent varnish.

Varnishing and plastic laminating must be assessed in advance. The varnish, coated with an offset machine, is almost fully absorbed and therefore it does not improve gloss or protection. Screen-printing varnishing achieves better results, although it is often necessary to perform two shots to achieve a distinctly evident result. The surface roughness, typical of uncoated papers, may give rise to micro defects with plastic laminating caused by incomplete adhesion of the film to the substrate. Good results with major processing operations such as cutting, die-cutting, scoring, folding and gluing.
