Gravür Baskı için Merck Efekt Pigmentleri


Merck’in efekt pigmentleri solvent-bazlı, su-bazlı ve UV-boya polimerizasyonu film baskı sistemlerinde kullanılabilir; çevre dostu geri dönüşümün yanı sıra değişik substratlar üzerinde yaratıcılık, özellikler göz alıcı ve yüksek-kalite efektler, gıda paketleme uygulamalarına uygunluk sağlarlar. Maksimum efekt elde etmek için gravür baskı ile ilgili bazı ipuçlarını dikkate almalısınız. Efekt pigmentleri substrata tüm partiküllerin aynı yönlendikleri, homojen bir tabaka halinde düzenli bir şekilde uygulanması gerekir.

Gravure Printing

Effect pigments from Merck are especially well-suited for gravure printing. The color layer thicknesses and smooth printing images, which can be achieved using this printing technique, allow very strong effects.

For the best results, the print color and viscosity must be adjusted to the material to be printed and the printing speed. The printing form is the deciding factor for the quality of printing ink transfer and emptying of the cells. The particle size, screen count and cell geometry must also be considered equally when printing with effect pigments. By using the laser engraving technique in cylinder manufacturing, a better transfer behavior of the effect pigments onto the material to be printed is achieved.

Our recommendations for the application of effect pigments in gravure printing:

Pigment Particle Size Screen Count Lines/cm
< 15 μm 70
5–25 μm
10–60 μm 70–60
10 –100 μm 60–48
10 –125 μm
Cells Engraved Cells Etched
Crosswise Cell (pressed)
Aqueous Print Systems Cell/Wall-Ratio:
140° engraving not lower than 6 : 1, better 10 : 1 or higher
Solvent Print Systems Etching Depth:
120° engraving 20 μm to maximum 54 μm
