Special paper is different from ordinary paper in printing. Today, let us know the problem that should be paid attention to when printing special paper albums.

1, grain

When printing with special paper, pay attention to whether there is any conflict between the direction of the grain and the bookbinding, save the cost with the most economical paper-opening method, and achieve good results; the paper with rich surface texture and clear grain, the ink may not be printed during printing. Focusing on the paper will cause slight leaks along the lines. Some special papers will be uneven. If the fineness of the dots is high, they cannot be used. Some domestic pearlescent papers are different from imported pearlescent papers in that they are inked. The domestic paper is poorly colored, usually darker after printing. Pearlescent paper avoids such problems; therefore, it is not recommended to use domestic pearlescent paper for clothing catalogues with high color and color requirements. However, some catalogue designs are also available with domestic pearlescent paper. This mainly depends on the design artwork and the customer's requirements for the printing effect of the album. After all, the imported paper will be much more expensive.

2, ink

Special paper with a particularly smooth surface, poor ink absorption, and scratching when not paying attention to it when printing. Therefore, it is better to use a quick-drying ink, and to add a drying oil which can promote the rapid drying of the ink in each color ink, to improve the drying speed of the ink, and to avoid the paper surface sticky fault when printing.

For special papers with high surface smoothness, such as pearl paper, ice white paper, high-color smooth paper, etc., the ink color should not be too saturated during printing, and the normal ink supply amount can be used. Because the smoother the surface of the paper, the poorer the ink absorbing property, the larger the amount of ink supplied, the more likely the paper back is dirty.

Special paper with rough surface, such as hand-made paper, double-adhesive paper, rice paper, kraft paper, writing paper, Daolin paper, etc., feels grainy and not smooth. When printing, the paper absorbs ink well, and the ink penetrates into the grain of the paper. After the ink is dried, the color of the printed product observed with the naked eye becomes lighter and the printing quality is also lowered. Therefore, for this special paper, the amount of ink supplied during printing is larger than usual, and the saturation requirement is also higher.

3, test print

When printing special paper, each time the machine is turned off, it will vibrate due to the pressure of the machine, which makes the first 10 printed products darker and the color is unstable. Especially when printing flat net jobs, too many downtimes will result in more waste. In addition, due to the high price of special paper, the amount of material given by the staff when placing the order is very small, and the printing requirements of special paper are higher than the general paper. If the usual printing habits are used, it is difficult for the captain to guarantee the number of printing. And quality. Therefore, the captain's assistant must place 10 sheets of other thickness of white paper or single-sided white paper on the special paper of the paper-feeding table in the gap of the paper-receiving board. (There is a printed piece of work, mostly after quality inspection. The waste left behind is white on the back, which can be used to run on the printing press, etc.). When this is turned on, it will first print single-sided white paper or other thickness of white paper. When special paper is printed, the color can be stabilized and unified, thus ensuring the printing quality of special paper.

4, dry

Different special papers have different ink absorbing properties. Paper with a smooth surface is not easy to dry. It must be placed for a long time. After drying, it will be sorted, otherwise it will easily cause back smudging.

Special paper printing is not an easy task. Before printing, we must carefully and carefully control all aspects to ensure the smooth progress of printing production.
