In the printing process of cartons, quality problems caused by inadequate pre-press plate making occur from time to time, ranging from waste of materials and man-hours to waste of products and serious economic losses. In order to prevent the occurrence of the above problems, the author believes that the following aspects should be paid attention to. small cookie boxes
(1) When different types of cartons need to be assembled on one printing plate for printing, if the products with the same or similar color tone are not assembled in the same vertical position during the imposition, it may appear that the A product can meet the proofing standard, and the B product can meet the proofing standard. cookie cake boxes The product of type C is basically close to the standard of the proofing draft, the product of type C has a slight color difference from the proofing draft, and the color difference between the product of type D and the proofing draft is relatively large. Therefore, products with warm tones, cool tones, and mid-tones should be put together in the same vertical position during imposition, so as to print high-quality products. cookie box packaging.regular cigarette case
(2) If the non-graphic part of the carton is placed at the mouth during imposition, and if the continuous tone image is not placed at the trailing end, but flat screen or solid, then “ghosting” will easily occur during printing. Seriously affect product quality. At this time, the non-graphic part should be placed at the trailing tip, so that there will be no “ghosting”. boxed cake cookies
(3) When imposing, it should also be noted that the carton finished line cannot be omitted in order to save film, but rely on the printing and printing personnel to calculate the position of the mouth and the finished product, which will greatly affect the production efficiency, and may also be caused by printing The momentary negligence of the printer and the printing staff caused a major accident. crumbl cookie party box
(4) The output film usually does not contain the marking line of the drawing gauge, but if the gripper and the trailing tip are blank, it will bring great inconvenience to the printing and positioning of the carton. For this, it is necessary to make a gauge marking line on the film. For packaging cartons that do not need to be mounted with corrugated cardboard, the pull-gauge marking line is made on the body; for packaging cartons that need to be mounted with corrugated cardboard, the pull-gauge marking line is made on the outer part. crumble cookie box
(5) Ensure that the film meets the printing requirements. After the film is output, carefully check whether the graphics on the film are consistent with the proofing draft (the carton cutting line used as the check benchmark must be standardized). box chocolate chip cookies.preroll king size box
(6) Ensure the correct registration between different films. This is because a set of films is generally output twice, and its overprint accuracy is easily affected by some objective factors. Once the output film has quality problems, it should be remade. cookie packaging boxes
(7) Carefully compare the film and the proofing draft before printing. If the film density of the main color is too high, the exposure time during printing should be increased to avoid heavy printing; if the density is too small, the exposure time during printing should be reduced.
