偏色:原因可能有原稿質量較差、制版不準確、曬版條件控制不一致、墨色控制步好、看樣臺光源不標準等顏色暗淡,不鮮艷:濟南印刷廠認為可能有原稿質量較差、制版曲線設計不佳、分色片密度較低、曬版不實印跡過淺、印刷壓力不足、印刷機老化、潤版液過量、紙張粗糙、白度過低等。
Color deviation: The reasons may include poor original quality, inaccurate plate making, inconsistent plate setting conditions, good ink color control steps, non-standard sample table light source, etc. The color may be dim and not bright. Jinan Printing Factory believes that there may be poor original quality, poor plate making curve design, low color separation film density, inaccurate plate setting, too light imprints, insufficient printing pressure, aging printing machine, excessive fountain solution, rough paper, and low whiteness.
文字發水:原因可能有陽圖密度較低、膠片灰霧度較大、曬版不實印跡過淺、印刷壓力不足、印刷機老化、潤版液過量、油墨量不足等。
Text moisture: The reasons may include low positive image density, high film haze, inaccurate printing, insufficient printing pressure, aging of the printing machine, excessive fountain solution, insufficient ink volume, etc.
糊版:由于印版圖文部分溢墨,造成承印物上的印跡不清晰,屬膠印印品故障。
Paste plate: Due to ink overflow in the image and text of the printing plate, the imprint on the substrate is not clear, which is a malfunction of offset printing.

Plate drop: The subtle tone of the graphic and text on the flat printing plate becomes lighter, the dot and line area decreases, and even loses ink affinity.
網點增大:承印物上網點面積比印版上相應部分的網點面積增大。
Dot increase: the dot area of the substrate is larger than that of the corresponding part of the printing plate.
堆墨:油墨或其他物質沉積在墨輥或橡皮布上,形成浮雕狀的沉積物,影響油墨和印跡轉移。
Stacking ink: Ink or other substances deposit on ink rollers or blanket, forming embossed deposits that affect ink and imprint transfer.
脫墨:金屬墨輥受濕潤液侵蝕發生氧化而排斥油墨的現象。
Deinking: The phenomenon of metal ink rollers being eroded by wetting solution and oxidizing, resulting in the rejection of ink.
油墨乳化:印刷過程中油墨吸收潤濕液的現象或由于油墨中吸收潤濕液過多而造成的印刷故障。
Ink emulsification: The phenomenon of ink absorbing wetting liquid during the printing process or printing malfunction caused by excessive absorption of wetting liquid in the ink.
拉毛:印刷過程中,因油墨太黏或紙張表面強度差異致紙張纖維、填料或涂料從紙張表面脫落或被拉掉。
Brushing: During the printing process, paper fibers, fillers, or coatings may detach or be pulled off the surface of the paper due to excessive ink adhesion or differences in surface strength.
印刷故障:在印刷過程中影響生產正常進行或造成印刷品質量缺陷的現象之總稱。
