畫冊設(shè)計印刷是一種靠視覺仲裁的宣傳品，畫冊印刷的質(zhì)量好壞取決于許多因素，圖片像素、紙張?zhí)匦缘?，紙張?zhí)匦詿o疑是其中一項重要因素。性能優(yōu)良的紙張，能完整地完成油墨轉(zhuǎn)移，使圖文清晰、飽滿地再現(xiàn)于紙張上，從而獲得令人滿意的圖冊。
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.
在畫冊印刷過程中，墨膜轉(zhuǎn)移到紙張表面，并填充了紙面的凹凸不平，使印刷品表面相當(dāng)平滑。畫冊成品墨膜表面對光的鏡面反射決定著畫冊成品光澤的大小，而墨膜表面又同紙張?zhí)匦悦芮邢嚓P(guān)。
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.
在畫冊印刷中，墨膜厚度是影響畫冊光澤的主要因素。在紙張較大限度吸收油墨的連結(jié)料以后，剩余的連結(jié)料仍保留在墨膜中，它可以有效地提高畫冊的光澤。墨膜越厚，剩余的連結(jié)料越多，越有利于提高印刷品的光澤。研究發(fā)現(xiàn)：光澤隨墨膜厚度提高的趨勢，因不同的紙張而有所不同。為相同油墨在四種不同紙張上印刷所得畫冊光澤與墨膜厚度的關(guān)系曲線。
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.
盡管油墨相同，但不同紙張所形成的畫冊光澤隨墨膜厚度而變化的趨勢是不同的。高光澤涂料紙在墨膜較薄時，其畫冊光澤隨墨膜厚度的增加而降低，這是由于墨膜掩蓋了紙張本身原有的較高的光澤，而墨膜本身形成的光澤又由于紙張吸收而降低。隨著墨膜厚度的增加，紙張本身原有的較高的光澤就越難透過墨膜反映出來。
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.
當(dāng)墨膜厚度達到1.5μm時，紙張對連結(jié)料的吸收基本飽和。之后，隨著墨膜厚度的繼續(xù)增加，保留連結(jié)料越多，光澤也就不斷提高。涂料紙板印刷品在墨膜較薄時光澤隨墨膜厚度的增加迅速提高，在墨膜厚度增加到3.8μm以后，光澤便不再隨墨膜厚度的增加而提高。但是無論何種紙張，光澤隨墨膜厚度增加而提高的量都應(yīng)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.
