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）拼版时如果将纸盒的非图文部分放于叼口处，而拖梢处放的不是连续调图像，是平网或实地的话，那么印刷时就很容易产生“鬼影”德鲁巴，严重影响产品质量。此时应将非图文部分放于拖梢处，这样就不会出现“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）拼版时还应注意不能为了节省胶片而将纸盒成品线省去，而是依靠晒版和印刷人员计算叼口和成品的位置，这样会大大影响效率，还可能会因为晒版和印刷人员一时疏忽人物，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）输出的胶片上通常不含拉规标识线，但如果遇到叼口与拖梢均为空白的情况，会给纸盒的印刷定位带来极大不便。对此，有必要在胶片上制作出拉规标识线。凡是不需要裱瓦楞纸板的包装纸盒，拉规标识线制作于靠身部位；需要裱瓦楞纸板的包装纸盒软包装，拉规标识线制作于朝外部位。 检测系统及仪器

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）确保胶片符合印刷要求，胶片输出后认真核对胶片上的图文是否与打样稿一致（作为核对基准的纸盒刀版线须规范）。

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）保证不同胶片之间的正确套准，这是因为一套胶片一般分两次输出，其套印精度很容易受到一些客观因素的影响。输出的胶片一旦出现质量问题，应重新制作。

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）晒版前应认真比较胶片与打样稿金属包装，如果主色调的胶片密度偏大，就应加晒版时的曝光时间，避免印刷色调偏重；如果密度偏小，则应减少晒版时的曝光时间，以免网点丢失影响色彩再现。

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.
