    公司畫冊印刷銳化工具

銳化工具包括四個功能選項：公司畫冊印刷銳化、銳化邊緣（ SharpenD)、較多銳化( Sharpen more)和虛光蒙版( Unsharpen Mask)。

其中銳化、銳化邊 緣和較多銳化都沒有參數控制，公司畫冊印刷調節時不能控制清晰度調整的幅度，只有虛光蒙版具有參數控制來調節清晰度。

故最常用到銳化(smem)、較多銳化( Sharpen. More)、公司畫冊印刷銳化邊緣( Sharpen Edge)濾鏡 均是通過提高與周圍像素點的對比度來提高圖像的清晰度。

但後者效果比前者明顯。銳化邊緣濾鏡僅銳化圖像的邊緣，公司畫冊印刷即對圖像中具有最強對比度的區域（邊界）進行銳化處理。

虛光蒙版USM( Unsharpen Mask)公司畫冊印刷一般是在圖像不清晰時才用到 Unsharp Mak進行清晰度強調，但並不是強調程度越高越好，強調過頭會給圖像帶來噪聲或白邊。
