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(shí)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(xù)調(diào)圖像，是平網(wǎng)或?qū)嵉氐脑挘敲从∷r(shí)就很容易產(chǎn)生“鬼影”德魯巴，嚴(yán)重影響產(chǎn)品質(zhì)量。此時(shí)應(yīng)將非圖文部分放于拖梢處，這樣就不會(huì)出現(xiàn)“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(shí)還應(yīng)注意不能為了節(jié)省膠片而將紙盒成品線省去，而是依靠曬版和印刷人員計(jì)算叼口和成品的位置，這樣會(huì)大大影響效率，還可能會(huì)因?yàn)闀癜婧陀∷⑷藛T一時(shí)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(guī)標(biāo)識(shí)線，但如果遇到叼口與拖梢均為空白的情況，會(huì)給紙盒的印刷定位帶來(lái)極大不便。對(duì)此，有必要在膠片上制作出拉規(guī)標(biāo)識(shí)線。凡是不需要裱瓦楞紙板的包裝紙盒，拉規(guī)標(biāo)識(shí)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(guī)標(biāo)識(shí)線制作于朝外部位。 檢測(cè)系統(tǒng)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. Detection system and instrument

5:（5）確保膠片符合印刷要求，膠片輸出后認(rèn)真核對(duì)膠片上的圖文是否與打樣稿一致（作為核對(duì)基準(zhǔn)的紙盒刀版線須規(guī)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(zhǔn)，這是因?yàn)橐惶啄z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(xiàn)質(zhì)量問(wèn)題，應(yīng)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(yīng)認(rèn)真比較膠片與打樣稿金屬包裝，如果主色調(diào)的膠片密度偏大，就應(yīng)加曬版時(shí)的曝光時(shí)間，避免印刷色調(diào)偏重；如果密度偏小，則應(yīng)減少曬版時(shí)的曝光時(shí)間，以免網(wǎng)點(diǎn)丟失影響色彩再現(xiàn)。

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.
