紙盒包裝的拼接排版要注意什么?

1:(1)不同種類的紙盒需要拼在一張印版上進行印刷時凹印,如果拼版時色調相同或相近的產品沒有拼在同一縱向位置上,可能會出現A款產品能達到打樣稿標準,B款產品基本接近打樣稿標準,C款產品與打樣稿有輕微色差,D款產品與打樣稿色差較大的現象。因此平版印刷,在拼版時應將暖色調、冷色調、中間色調的產品拼在同一縱向位置上,以便于印刷出的產品。
1: (1) Different kinds of cartons need to be assembled on a printing plate for gravure printing. If products with the same or similar colors are not assembled in the same longitudinal position during assembly, there may be a phenomenon that product a can meet the proofing standard, product B is basically close to the proofing standard, product C has a slight color difference with the proofing draft, and product D has a large color difference with the proofing draft For plate printing, warm tone, cold tone and intermediate tone products shall be put together in the same longitudinal position during plate making, so as to facilitate the printed products.
2:(2)拼版時如果將紙盒的非圖文部分放于叼口處,而拖梢處放的不是連續調圖像,是平網或實地的話,那么印刷時就很容易產生“鬼影”德魯巴,嚴重影響產品質量。此時應將非圖文部分放于拖梢處,這樣就不會出現“鬼影”。
2: (2) when making up, if the non graphic part of the carton is placed at its mouth, and the trailing tip is not continuously adjusted image, but flat screen or field, it is easy to produce "ghost" drupa during printing, which seriously affects the product quality. At this time, the non graphic part should be placed at the trailing tip, so that there will be no "ghost".

3:(3)拼版時還應注意不能為了節省膠片而將紙盒成品線省去,而是依靠曬版和印刷人員計算叼口和成品的位置,這樣會大大影響效率,還可能會因為曬版和印刷人員一時疏忽人物,造成重大事故。
3: (3) when making up, it should also be noted that the carton finished product line should not be omitted in order to save film, but rely on the printing and printing personnel to calculate the position of its mouth and finished product, which will greatly affect the efficiency, and may cause major accidents due to the negligence of printing and printing personnel.
4:(4)輸出的膠片上通常不含拉規標識線,但如果遇到叼口與拖梢均為空白的情況,會給紙盒的印刷定位帶來極大不便。對此,有必要在膠片上制作出拉規標識線。凡是不需要裱瓦楞紙板的包裝紙盒,拉規標識線制作于靠身部位;需要裱瓦楞紙板的包裝紙盒軟包裝,拉規標識線制作于朝外部位。 檢測系統及儀器
4: (4) The output film usually does not contain the pull gauge identification line, but if the mouth and trailing tip are blank, it will bring great inconvenience to the printing and positioning of the carton. For this, it is necessary to make the pull gauge identification line on the film. For the packaging carton that does not need to be mounted with corrugated board, the pull gauge identification line shall be made at the body part; for the packaging carton that needs to be mounted with corrugated board, it shall be soft packaged, The pull gauge identification line is made at the outward part.

5:(5)確保膠片符合印刷要求,膠片輸出后認真核對膠片上的圖文是否與打樣稿一致(作為核對基準的紙盒刀版線須規范)。
5: (5) ensure that the film meets the printing requirements. After the film is output, carefully check whether the pictures and texts on the film are consistent with the proofing draft (the carton knife plate line as the check benchmark must be standardized).
6:(6)保證不同膠片之間的正確套準,這是因為一套膠片一般分兩次輸出,其套印精度很容易受到一些客觀因素的影響。輸出的膠片一旦出現質量問題,應重新制作。
6: (6) ensure the correct registration between different films, because a set of films is generally output in two times, and its overprint accuracy is easily affected by some objective factors. Once the output film has quality problems, it should be made again.
7:(7)曬版前應認真比較膠片與打樣稿金屬包裝,如果主色調的膠片密度偏大,就應加曬版時的曝光時間,避免印刷色調偏重;如果密度偏小,則應減少曬版時的曝光時間,以免網點丟失影響色彩再現。
7: (7) before printing, carefully compare the metal packaging of the film and the proofing draft. If the film density of the main color is too high, the exposure time during printing shall be added to avoid printing color bias; if the density is too low, the exposure time during printing shall be reduced to avoid dot loss affecting color reproduction.
