Problems solved by technology

[0002] Since the advent of UV curable ink, it has been widely used on non-ferrous metal composite and transfer paper, such as mirror silver, grating laser card, plain laser card, plain transfer laser card, composite silver card, grating transfer laser card, silver card, single copper The use of composite transfer laser paper, etc., solves the problems of common ink printing on non-ferrous metal cardboard, such as non-drying, scratches, uneven hair, etc., improves the proofing progress and production efficiency, and reduces product consumption. , improved the product quality and improved the popularity of the enterprise in the minds of customers. After more than ten years of experiments, developed and developed a variety of technological UV inks and screen inks such as snowflakes, fission, refraction, freezing point, marble and other screen printing inks, In terms of varnish, reverse varnish, UV varnish, and matte varnish make the printed products look beautiful and improve the grade at multiple levels. It is counterproductive. Some things are not as simple as we imagined. The performance of each manufacturer's ink is different. However, some ink manufacturers have poor bronzing effects on small areas, and only part of the bronzing on large areas can be stamped, or they cannot be stamped at all.
And because the ink ratio of each batch is not exactly the same, there are different phenomena.

Embodiment 1

[0016] By adopting the method of the present invention, the part to be bronzed on the non-ferrous metal cardboard is printed with UV matt oil for one layer before bronzing, and then bronzing is performed. In this way, it will not be affected by the oxidation phenomenon of ink printed on the surface of the paper due to the multi-color sequence proofing and printing that require multiple dryings during the proofing process, making it difficult to bronzing. Such as figure 1 As shown, the effect after bronzing using the method of the present invention is very obvious, plump and smooth, and the phenomenon of hair loss, burrs, and flying gold is easily solved, ensuring product quality, and improving the progress of proofing and printing.

Embodiment 2

[0018] Each batch of UV ink produced by an ink manufacturer is different. Sometimes it cannot be stamped and proofed normally, causing irreparable losses to printing. Sometimes the inks are pressed against each other and cannot be printed normally, not to mention the guarantee of stamping. After many times of glazing, the UV diluent cannot be bronzed normally. The method of the present invention is used to print a layer of UV matt oil on the part to be bronzed on the non-ferrous metal cardboard before bronzing, and then bronzing, the bronzing effect very good. and figure 2 Shown did not adopt this method bronzing effect ratio, it can be seen that figure 2 The bronzing pattern has obvious rough edges and blooming phenomenon.

Embodiment 3

[0020] When the proofing is done after the transfer, because the proofing work order is not clearly seen, the whole batch of proofing products are all put on UV light without bronzing, and a layer of UV sub-layer is applied on the part or the whole plate by the method of the present invention. After the UB matte oil in the varnish, and then bronzing, the bronzing effect is very good.

Abstract

The invention discloses a method for improving the bronzing effect on a non-ferrous metal paperboard, which comprises printing layer of UV matte oil on the part of the non-ferrous metal paperboard for bronzing before bronzing, and then performing the bronzing. If the matte effect is needed, the back part of a part needing the bronzing on the non-ferrous metal paperboard can be printed with a layer of the UV matte oil, and then the part needing the bronzing on the non-ferrous metal paperboard is printed with a layer of the UV matte oil again. Before the bronzing, if the UV matte oil is used for printing, for not influencing the bronzing effect, the part needing the bronzing on the non-ferrous metal paperboard is printed with a layer of UB matte oil contained in the UV matte oil before performing the bronzing, and then the part needing the bronzing is subjected to the bronzing.
