If different types of display boxes need to be printed on a printing plate, if products with the same or similar color tone are not located in the same vertical position, then it may happen that some products can meet the standard of sample drafts, but some products do not. To the standard situation of the sample manuscript. And there may be relatively large and unusual gaps between different products. Therefore, in order to complete high-quality display box printing, warm, cool, and mid-tone products should be put together in the same vertical position.
In addition, if the non-graphic part of the color box is placed at the mouth during imposition, and the continuous adjustment image is not placed at the trailing point, but is laid on the spot, then ghost images will be generated, which will The quality of the product caused great damage.
There is also a very important point to note, that is, the color box product line cannot be omitted in order to save costs, because this will greatly affect the production efficiency, and the worst thing is that this is likely to be caused by the temporary negligence of the printing staff. , Causing a very serious accident.
Also, there is usually no rule marking line on the film, so if the gripper and the trailing tip are blank, it is not convenient for the display box to print. Therefore, it is necessary to make the rule marking line on the film. The display box does not need to be packaged in corrugated cardboard, so the marking line needs to be leaning against it, and if necessary, it should be made towards the outside.
Then it is necessary to make sure that the produced film meets the requirements. After outputting the film, carefully check whether the above graphics and text are consistent with the sample draft.
Also, it is necessary to ensure that the film and the best film are correctly registered. This is mainly because the film is usually outputted twice. If the film has quality problems, it must be reproduced.
The last is to carefully compare whether there is a difference between the proofing draft and the proof before printing. If the density of the film is too high, then the exposure time should be increased. If the density is too small, the exposure time during printing should be reduced to avoid quality problem.
