画册设计印刷是一种靠视觉仲裁的宣传品,画册印刷的质量好坏取决于许多因素,图片像素、纸张特性等,纸张特性无疑是其中一项重要因素。性能优良的纸张,能完整地完成油墨转移,使图文清晰、饱满地再现于纸张上,从而获得令人满意的图册。
Album design and printing is a kind of publicity material relying on visual arbitration. The quality of album printing depends on many factors, such as picture pixels and paper characteristics. Paper characteristics are undoubtedly one of the important factors. The paper with excellent performance can complete the ink transfer completely, so that the pictures and texts can be clearly and fully reproduced on the paper, so as to obtain a satisfactory atlas.
在画册印刷过程中,墨膜转移到纸张表面,并填充了纸面的凹凸不平,使印刷品表面相当平滑。画册成品墨膜表面对光的镜面反射决定着画册成品光泽的大小,而墨膜表面又同纸张特性密切相关。
In the process of album printing, the ink film is transferred to the paper surface and filled with the uneven surface of the paper, making the surface of the printed matter quite smooth. The specular reflection of the ink film surface of the finished album determines the gloss of the finished album, and the ink film surface is closely related to the characteristics of the paper.
在画册印刷中,墨膜厚度是影响画册光泽的主要因素。在纸张较大限度吸收油墨的连结料以后,剩余的连结料仍保留在墨膜中,它可以有效地提高画册的光泽。墨膜越厚,剩余的连结料越多,越有利于提高印刷品的光泽。研究发现:光泽随墨膜厚度提高的趋势,因不同的纸张而有所不同。为相同油墨在四种不同纸张上印刷所得画册光泽与墨膜厚度的关系曲线。
In album printing, the thickness of ink film is the main factor affecting the gloss of album. After the paper absorbs the binder of ink to a large extent, the remaining binder is still retained in the ink film, which can effectively improve the luster of the album. The thicker the ink film, the more remaining binder, which is more conducive to improving the luster of the printed matter. It is found that the trend of gloss increasing with ink film thickness varies with different paper. It is the relationship curve between the gloss of the album printed with the same ink on four different papers and the thickness of the ink film.
尽管油墨相同,但不同纸张所形成的画册光泽随墨膜厚度而变化的趋势是不同的。高光泽涂料纸在墨膜较薄时,其画册光泽随墨膜厚度的增加而降低,这是由于墨膜掩盖了纸张本身原有的较高的光泽,而墨膜本身形成的光泽又由于纸张吸收而降低。随着墨膜厚度的增加,纸张本身原有的较高的光泽就越难透过墨膜反映出来。
Although the inks are the same, the variation trend of album gloss formed by different papers with ink film thickness is different. When the ink film of high gloss coating paper is thin, the album gloss decreases with the increase of the ink film thickness, because the ink film masks the original high gloss of the paper itself, and the gloss formed by the ink film itself decreases due to the absorption of the paper. With the increase of ink film thickness, the original high gloss of the paper itself is more difficult to be reflected through the ink film.
当墨膜厚度达到1.5μm时,纸张对连结料的吸收基本饱和。之后,随着墨膜厚度的继续增加,保留连结料越多,光泽也就不断提高。涂料纸板印刷品在墨膜较薄时光泽随墨膜厚度的增加迅速提高,在墨膜厚度增加到3.8μm以后,光泽便不再随墨膜厚度的增加而提高。但是无论何种纸张,光泽随墨膜厚度增加而提高的量都应有一定的限度。
When the ink film thickness reaches 1.5 μ M, the absorption of paper to binder is basically saturated. Then, as the thickness of the ink film continues to increase, the more binder is retained, and the luster will continue to improve. When the ink film of Coated Paperboard Printing is thin, the gloss increases rapidly with the increase of ink film thickness, and the ink film thickness increases to 3.8 μ M later, the gloss no longer increases with the increase of ink film thickness. However, no matter what kind of paper, the gloss should be improved with the increase of ink film thickness.
