In the process of wine box printing, the quality problems caused by inadequate plate making before printing often occur, which may lead to waste of materials and working hours, or even lead to product scrapping, resulting in serious economic losses. In order to eliminate the above problems, Risun-print thinks that we should pay attention to the following aspects.

         (1) When different kinds of wine boxes need to be put together on a printing plate for printing, if the products with the same or similar hue are not put together in the same vertical position, there may be a phenomenon that product a can meet the proofing standard, B product is basically close to the proofing draft standard, C product has slight color difference with the proofing draft, and D product has large color difference with the proofing draft. Therefore, the warm tone, cold tone and middle tone products should be put together in the same vertical position in order to print high-quality products.

      (2) If the non graphic part of the wine packaging box is placed at the mouth of the plate, but there is no continuous adjustment image at the trailing end, it is flat screen or on the spot, then it is easy to produce "ghost image" in printing, which seriously affects the product quality. At this time, the non graphic part should be placed at the trailing end, so that there will be no "ghost".

     (3) It should also be noted that the finished product line of wine packaging color box should not be omitted in order to save film. Instead, the position of mouth and finished product should be calculated by the printing and printing personnel. This will greatly affect the production efficiency, and may cause serious accidents due to the negligence of the printing and printing personnel.

          (4) The output film usually does not contain the gauge mark line, but if the mouth and trailing tip are blank, it will bring great inconvenience to wine box printing positioning. In this regard, it is necessary to make the marking line of the drawing gauge on the film. If it is not necessary to mount the corrugated board wine packaging color box, the pull gauge identification line shall be made on the body part; if the corrugated board wine box needs to be mounted, the pull gauge identification line shall be made at the outward position.

  (5) Ensure that the film meets the printing requirements. After the film is output, carefully check whether the picture and text on the film are consistent with the proofing draft (the knife plate line of wine box  must be standardized).

       (6) To ensure the correct registration between different films, this is because a set of film is usually output twice, and its overprint accuracy is easily affected by some objective factors. The output film should be remade in case of quality problems.

  (7) Before printing, the film should be carefully compared with the proofing draft. If the film density of the main tone is too high, the exposure time should be added to avoid the printing tone bias; if the density is too small, the exposure time should be reduced to avoid the loss of dot and affecting the color reproduction.。Websit:www.risunprint.com  Contact: Ava  Mobile / Whatsapp: 0086- 13760600787
