Post-production is an indispensable process in the inkjet industry, and plays an important role in the success or failure of the entire work and the guarantee of quality. A fast and refined post-production will not only make the work icing on the cake, but also create greater economic benefits and corporate reputation for the company. Post-production concepts are extensive, and basically all post-production work is post-production. For example: output, cutting, laminating, mounting, stitching, etc. Next, a little explanation of the later work.
Output
The first work after the image design is completed is the output. In this process, the output image must be merged with all layers (layer), generally need 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 the number of points in the image file, the output accuracy can be basically achieved by maintaining the upper and lower of 100dpi. If the image of the image to be output is large, the number of points can be appropriately reduced. There are several issues to be aware of in this process: First, inkjet printing is different from printing, and the colors of inkjet printing are much more beautiful and beautiful than printing. Therefore, the inkjet drawing must be set to RGB mode, not CMYK mode. The surface of the inkjet image is often very large, and some defects that are not easy to detect on the printed matter will become obvious and exaggerated after being enlarged and output, and this cannot be found through the sample, so the inkjet image must be enlarged to 100% after the production is completed Double check. For pictures with a lot of text, you must check them carefully. And because there is no ready-made color mark in the output of the inkjet printing, it is necessary to rely on experience in grasping the color deviation. This is the purpose of making the sample.
Tailoring
After the screen output is completed, the machine will automatically cut the paper. If there is a big difference between the size of the screen and the paper, you need to cut it neatly. When we cut the film, we should also use scissors to align along the marking line, because this will facilitate the work of applying the film in the cover film, and can ensure the quality and success rate.
Laminating
"Laminating" work is a "three-person" project, which requires high cooperation of personnel. A successful laminating work is the result of highly coordinated "paper feeding", "film pulling" and "rock". The specific operation is as follows; in the case of ensuring that the width of the drawing is appropriate, the length of the film should be appropriately lengthened (generally 20cm). The first is to adjust the knob of the roller, until the hand feels that there is no resistance at all, the knob is slightly tight. Feed the membrane flat to ensure that it does not deflect or squeeze during the movement of the membrane. Then, pull up the film, when the film is about to reach the end, hold the roller steady, pull the film firmly to ensure that the end is flush. At this time, the person who pulls the film and hangs the protective film while "feeding" can enter the picture (one end of the picture should be flush) to ensure that the picture is flat, and the two sides are parallel to the film. When you are ready to order, you can let the "rock" rocker shake slowly, and see if there is no problem, then move forward to the head at a uniform speed. During this process, the feeder should carefully check whether there is anything like hair on the screen, and try to remove it. After laminating, it will enter the "cutting" work.
Mounting board
When the customer requests to add a board, we will enter the next board mounting process, and there are two commonly used technologies for table mounting, namely adhesive paper type and 3M glue type. Compared with the two, the adhesive type will be more durable.
Adhesive type
Cut the picture to the required size, place it flat on the exhibition board, align the four sides, and use a heavy object in the middle or be pressed by a person. Peel off one end of the adhesive tape about 10 cm, stick it to the exhibition board, and then take it to the laminator to adjust the pressure until it just passes through the exhibition board. Enter the end that has been pasted on the screen, pull up the screen, one person pulls out the adhesive tape, and one person pushes the board to the end.
Spray type
For standard display panels with clips on all four sides (specification: 120cm × 90cm, 90cm × 60cm), we are more convenient to apply the glue spray method. Lay the display panel flat and place the picture on the display panel flat. In order to make the four sides of the picture better match the edges of the exhibition board, we first trim the picture along the two adjacent sides, and then use these two sides as a reference to align the edges of the exhibition board and fix the relative position of the picture and the exhibition board. Objects or pressed by others), lift one of the aligned sides and spray glue on the posters behind it. After half a minute, the two sides of the screen were pulled tightly and dropped at a uniform speed. At this time, a person presses the screen from the center of the screen to both sides with a scraper until the screen completely fits the display panel; the same method is used to lift the other end of the screen, apply glue after pressing, and finally use a paper knife along the clip of the display panel. Cut off the extra part of the picture, that is, finish the whole frame.
splice
When the picture requested by the customer is larger than the maximum printing size of the inkjet machine, we will output the pictures separately and then splice them together. When doing this kind of splicing work, the design and production of the picture is its premise, so every step There should be no mistakes. First of all, we need to figure out the stitching position of the picture, who is on the top and who is on the bottom, which one will be bigger and which one will be smaller. In the output process, because the picture to be output is the same picture, it is necessary to keep its color consistent and corresponding in size (for example, a certain width), and record the setting parameters at the time of output to ensure that it is correct. In the process of splicing, first cut the ends of the two paintings to be connected. Then flatten the screen on a large enough plane, put the screen in the correct relative position, fix it with glue strips, lift the front end of the upper picture connection part, spray glue (to cover the screen from being sprayed) Afterwards, use a scraper to press the screen tightly 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, and compact it, that is, stitch the picture together. The stitched picture must not be rolled up by vertical seams, so it is easy to produce wrinkles at the junction, this should be noted!
Honeycomb Blinds also called Cellular Shades. window covering used to block or filter light and insulate windows to save energy. Cell size can vary. Cell shapes hold trapped air and create a barrier between the window surface and the a room. we have different fabric style provide to you choose, you can choose half light shading style, also can choose full light shading style Cellular Shades.
