Precautions for the post printing process of inkjet products

post production is an indispensable process in the inkjet industry, which plays a very important role in the success or failure of the whole work and quality assurance. A fast and exquisite post production can not only make the work icing on the cake, but also create greater economic benefits and corporate reputation for the company. Post production has a wide range of concepts, and basically all design and production work is post production. For example: output, clipping, lamination, mounting, splicing, etc. Next, I will make a little explanation for the later work


the first job after the image design and production is output. In this process, the output image must merge all layers, and generally needs to be saved as TIF or Jpg format. If the image is made by Apple computer, the file must have an extension. For the setting of image file points, the output accuracy can be achieved by basically keeping it around 100dpi. If the image to be output has a large surface, the points can be reduced appropriately. There are several points to pay attention to in this process: first, spray painting is different from printing, and the color of spray painting is much more beautiful than printing. Therefore, RGB mode must be set instead of CMYK mode in inkjet drawing. The surface of the inkjet image is often large, and some defects that are not easy to detect on the printed matter will become obvious and exaggerated after amplification, which cannot be found through the small sample. Therefore, the inkjet image must be magnified to 100% and carefully checked after production. For pictures with many words, you should proofread them carefully. And because there is no ready-made color mark in the inkjet output, we should rely on experience to grasp the color deviation, which is the purpose of making small samples


after the picture is output, the machine will automatically cut paper. If there is a large difference between the picture size and the paper and it needs to be cut, it should be cut neatly. When we cut the film, we should also use scissors to follow the marking line, because this will facilitate the film work in the film covering, and better ensure the quality and success rate

film coating

China is a large country of refractory production. Film work is a three person project, which requires high cooperation of personnel. A successful film coating work is the result of the high coordination of paper feeding, film pulling and rock. The specific operations are as follows:; Under the condition that the drawing width is appropriate, the length of the film should be appropriately lengthened (generally 20cm). First, adjust the knob of the roller until you feel no resistance at all and the knob is slightly tight. Spread the membrane and feed it in, so as to ensure that there is no side deviation and extrusion during the process of membrane walking. Then, pull up the film. When the film is about to end, stabilize the roller and pull the film hard to ensure that the end is flush. At this time, the film puller droops the protective film and the paper feeder can enter the picture (one end of the picture should be flush) to ensure that the picture is flat and both sides are parallel to the film. When the total root mean square value of acceleration grms=... Formula (13 ⑵) (g) is ready, the rocker can shake slowly. After seeing that there is no problem, he can advance to the end at a uniform speed. In this process, the paper feeder should carefully check whether there are hair and other things on the screen and try to remove them. After the film covering is completed, the cutting work is started

plate mounting

when the customer requests to add plates, we will enter the next plate mounting process. There are two commonly used technologies for table mounting, namely, back glue paper type and 3M glue spraying type. Compared with the two, the adhesive backed type will last longer

back glue type

cut the picture to the required size, place it flat on the display board, align the four sides, and press the middle with a heavy object or someone. Uncover a 10 cm strip of adhesive on one end, paste it on the display board, and then take it to the laminating machine, and adjust the pressure until it just passes through the display board. Enter the pasted picture end, pull up the picture, pull out the adhesive paper by one person, and push the board to the end

glue spraying type

for standard display boards with card strips on four sides (specifications: 120cm 90cm, 90cm 60cm), it is more convenient for us to apply glue spraying method. Put the display board flat and the picture on the display board flatly. In order to make the four sides of the picture better match the edge of the display board, we first cut the picture along the two adjacent sides, and then align the edge of the display board based on the two sides, fix the relative position between the picture and the display board (press a heavy object on the picture or by others), lift one side of the aligned two sides, and spray glue on the subsequent display board. After half a minute, pull both sides of the screen tightly and fall at a uniform speed. At this time, one person presses the picture from the center of the picture to both sides with a scraper until the picture completely fits the display board; In the same way, lift the other end of the picture, spray glue and press it tightly. Finally, use a paper cutter to cut off the excess part of the picture along the card strip of the display board, that is, the whole picture is framed


when the picture required by the customer is larger than the maximum inkjet format of the inkjet machine, we will output the picture separately and then splice it together. When doing this kind of splicing work, the design, production and output of the picture is the premise, so every step should not be wrong. First of all, check the splicing position of the picture to find out who is on the top, who is on the bottom, which will be larger and which will be smaller. In the process of output, because the picture to be output is the same picture, its color must be consistent and its size must be corresponding (for example, the width must be certain), and the setting parameters during output must be recorded to ensure that it is correct. In the process of splicing, first cut the end of the two paintings to be connected. Then flatten the picture on a large enough plane, place the picture according to the correct relative position, fix it with adhesive tape, lift the front end of the connecting part of the upper picture, spray glue (to cover the picture from being sprayed), and then use a scraper to compact and stick the picture from the middle to both sides. Turn over the other end of the upper picture, spray glue on the connecting part of the lower picture, compact it, and the picture will be spliced. The spliced paintings can be used as degradable substitutes. The high cost surface must not be rolled up vertically, so it is easy to wrinkle at the junction. This should be noted
