According to the characteristics of gold and silver cardboard, laser paper (with laminating paper, transfer paper) the rational design of the printing layout

Gold and silver cardboard, laser paper surface brightness, reflectivity is relatively strong, it should be based on the characteristics of the material, in the layout design, we should pay attention to highlight the performance of the spectral color can not display gold and silver cardboard, laser paper unique metal Glossy, appropriate to reveal the surface of the metal hue, to express the artistic beauty of packaging.

Designed to field, lines, text, images of the combination of gold and silver cardboard, laser paper packaging, to avoid the use of too small bold and small Yinxian to prevent easy to affect the paste version of the printing quality. In the gold and silver cardboard, laser paper on the surface printed lines, text or transparent, bright small layout, contrast, color saturation is poor, should try to avoid such a design. Text, lines, borders and signs should preferably be printed on the background and designed to be dark so that they are eye-catching.

As the gold and silver cardboard, laser paper surface of the high brightness, trace of the overprint is not easy to be aware of the naked eye, so should try to avoid multi-color layout of each other with precision overprint. On the layout of the layout of precision overprint, should consider the edge of the light-colored overlay layout expansion of about 0.2mm, in order to avoid the overprint error and the emergence of obvious whitening phenomenon.

In addition, embossed gold and silver cardboard, laser paper should try to avoid printing small outlets, so as not to affect the layout of the subtle level of faithful and easy to paste paste phenomenon.

Using "deep ink India or India" printing process.

Gold and silver cardboard, laser paper surface is non-absorbent, ink printed up as long as it is by oxidation polymerization to achieve dry. This dry form of ink, once the ink layer thick, it is not easy to make inside and outside the ink layer to achieve complete drying, which will affect the normal overprint, but also likely to cause sticky quality problems. In order to avoid this problem, in the printing of the spot color ink, the ink should be appropriate to adjust the hue, so that the printing ink layer thinner, so that both in line with the requirements of the original printing hue, but also conducive to the rapid completion of overprint , And better prevent the phenomenon of sticky dirt.

On the printing field full version of the gold and silver cardboard, laser paper, you can also use the "second India" approach, first ink once India, and then in the overprint once, this is conducive to the rapid drying of the ink layer, and better To prevent sticky dirt phenomenon.

Technology Control of Anti - sticking Technology for Printing

Gold and silver cardboard, laser paper printing, the ink layer is suspended in the surface of the film surface, not quickly dry. If the process is not well controlled, it is prone to sticky dirt and affect the quality of the product printing.

Printing and anti-sticking control are important: the use of fine and uniform fine powder, the printing semi-finished products for powder and anti-stick; to avoid the use of high-speed printing, printing gold and silver cardboard, laser paper packaging machine speed, / Hour -5000 / hour range is appropriate; printing press online semi-finished products, should be used to separate the shelf stacking, each shelf stacked semi-finished products do not exceed 5cm; printing ink in the semi-dry, The paper stack is loosened and turned to allow the oxygen to enter the printed paper stack, which promotes the oxidation and drying of the printing ink layer. The printing process should keep the relative balance of ink and fountain solution with the same amount of fountain solution. Through the technical control of these processes, you can better prevent the sticky dirt.
