The famous painting and calligraphy identification should be traced back to the source, speaking from different dynasties. Before the Tang Dynasty landscape painting probably unbelievable, posing as the Western Han Dynasty calligraphy calligraphy styles are not believed. As long as the calligraphy and painting in painting style, Yu have probably understood that the counterfeit deception can be clearly identified.

　　對于名家作品，要了解名家的生平、藝術風格與創作題材范圍，名人字畫收購出售，更要了解他們的筆墨技法。名家的藝術表現技法是長期操練后而形成的，一般人要模仿難免有敗筆顯露，抓住某人筆法特點研究深，名人字畫收購群，則容易辨認偽作。

　　For the famous works, to understand the masters of life, art style and creative theme scope, celebrity pictures bought and sold, but also to understand their painting skills. The famous artistic techniques and the formation of long-term practice, people should imitate a flaw exposed, catch sb writing characteristics of the deep, celebrity calligraphy acquisition group, is easy to identify counterfeit.

　　紙、帛的鑒別 字畫是作于紙和帛之上的，帛的壽命一般百年左右，紙的壽命約在千年之內。當然，出土文物中的紙帛由于地下埋葬環境的不同，仍可能超越千年。

　　Identification of calligraphy and painting paper, silk is made on paper and silk, silk life hundred years or so, the life of paper in about a thousand years. Of course, the unearthed cultural relics in the underground buried paper silks in different environment, still may exceed the millennium.

　　例如絹帛在晉唐之前是單絲織成，直到宋代才發現雙絲織成的絹帛，比元明時期的絹顯得細密。由絹的質量類別可以斷定字畫年代。

　　For example, in the Jin Tang silk is woven monofilament before, until the Song Dynasty found the double silk fabric made of silk, silk than in Yuan and Ming Dynasty is fine. The quality of silk can be concluded in the calligraphy class.

　　紙，也有時代痕跡。隋唐之前，紙以麻料作原料，顯得纖維較租，紙張不夠細潔;隋唐之后，無錫名人字畫收購，樹皮被用來造紙，其紙質就比以前精細;北宋中期后，造紙原料多樣化，紙質也呈現多樣化了。

　　Paper, there are traces of the times. Before the Sui and Tang Dynasties, with linen paper as raw material, it is not enough to rent the paper fiber, fine clean; after the Sui and Tang Dynasties, the acquisition of Wuxi celebrity calligraphy and painting, the bark is used for papermaking, the paper is fine than before; the mid Northern Song Dynasty, the papermaking raw material diversification, the paper also presents the diversification.

　　實際上，民間收藏的字畫僅以明清以后時期多見，這是因為紙、絹本身難于歷經數百年保存的緣故。再加上造偽者的混淆，所以有人認為古字畫中相當部分是魚目混珠。 裝演鑒別 各個時代裝橫有其特色。

　　In fact, the folk collection of calligraphy and painting in the Ming and Qing Dynasties period to see, this is because the paper, silk itself is difficult to save because of hundreds of years. Plus made pseudo confusion, so some people think that the ancient painting is a considerable part of the fish. Installed to identify the characteristics of each era has its characteristics.

　　如元代宮廷藏畫選擇專人裝裱，大德四年“以古玉象牙為軸，以鸞鵲木錦碧天續為裝核”。明代書畫則在書畫卷增加了引首，有的還被寫上了字，立軸有寬邊、窄邊之分，有的還加了詩堂。清代宮廷書畫的裝核用料和技術形式都勝于明代，顯得更為講究。

　　If the court choose someone framed paintings, Dade four years "to the ancient jade Ivory axis, with Jin Bi Tian Luan magpie wood continued for nuclear". The Ming Dynasty calligraphy and painting in the painting volume increase guide, some are also written on the word, with wide and narrow vertical edge points, also added some poems of tang. In the Qing Dynasty, the calligraphy and painting materials and techniques of the court were better than that of the Ming dynasty.
