畫冊印刷文件格式：JPEG(jpg,jpeg)格式。​是聯合圖像專家組( Joint PhotographicExperts Group)標準的產物,JPEG正是其縮寫,因為PC機上規定擴展名最多只能使用3個字元,所以簡寫為JPG。

畫冊印刷文件格式：JPEG(jpg,jpeg)格式。是聯合圖像專家組( Joint PhotographicExperts Group)標準的產物,JPEG正是其縮寫,因為PC機上規定擴展名最多只能使用3個字元,所以簡寫為JPG。

是面向連續色調靜止圖像的一種壓縮標準。由於其高效的壓縮效率和標準化要求,目前已廣泛用於彩色傳真、靜止圖像、電話會議、印刷及新聞圖的傳送上。

它和TFF格式不同,它是一種有損的壓縮格式,在壓縮時被刪除的資料無法在解壓時被還原,所以JPEG文件並不適合放大觀看,存在一定程度失真,輸出成印刷品時品質也因此受到影響。

同樣一幅畫面,用JPEG格式儲存的文件,其大小是其他類型圖形文件的1/20~1/10。

一般情況下,JPEG文件只有幾十KB,而色彩數最高可達到24位,所以它被廣泛運用在 Internet上,以節約寶貴的網絡傳輸資源。

JPEG格式支持RGBCMYK和灰度顏色模式,但不支持 Alpha通道。

該格式主要用於圖像預覽和製作HTML網頁,但不適合製作印刷品。
