Website: Send Documents/Consultation QQ Consult Quote T18937476345 (Not Contact) There are three main methods of inkjet color correction: screen display method, color card color method, and color tone method. The on-screen display method adjusts the color of the image by adjusting the color displayed on the screen; the color-tone method tones the color by contrasting the colors in the color-card; the color-measuring method performs color measurement on the target color patch by means of a colorimeter and The measured result is entered into the computer and the color is printed. Principle of operation The on-screen display method adjusts the color of an image by adjusting the color displayed on the screen, usually by selecting or adjusting the color on the screen through the color menu. This method is very useful when coloring or starting toning, and is a common color grading method for designers. However, due to the principle of colorization of fluorescent screens and the principle of coloration of dyes on posters (fluorescent screens produce colors by mixing three RGB electron beams, and dyes express colors by absorbing light waves of certain colors), on the screen The colors that can be displayed cannot all be represented by the dye on the fabric, and the slight differences between the colors exhibited by the dye cannot be clearly displayed on the screen. Therefore, this is a general method for coloring inkjet pigments and cannot be used for accurate inkjet color correction. Printing details: 1. Display color, digital inkjet printer color correction. Color Management: Color management. For PC and Mac environments, full color management is divided into three steps: Calibrate, Profile, and Mapping. The source color space ---> corresponding working color space ---> is mapped according to the profile obtained after the characterization ---> output to a device that has been corrected. It is good practice to use a monitor to simulate the target—the color gamut of a digital inkjet printer. The display effect of the display made in this way is not good, but it is close to the printing effect of the printing machine, which is very helpful for the color display of the screen display. 2. Adjust the pattern artwork by comparing the display with the standard sample. Adjust the pattern artwork by comparing the display with the standard sample, and adjust the pattern to the display effect close to the standard sample. Because dyes are subtractively mixed, the saturation or vividness of the manuscript should be higher than the standard. Color card color method The color card method adjusts the printing color by contrasting the color in the color card. The operation process is: First, establish a color card model. One or more color modes can be selected to create a color card model, the color card model is a three-dimensional (Lab mode and RGB mode) or a group of three-dimensional (CMYK mode). Second, make a color card file. The 3D model can be decomposed into a 2D graph with one of the values ​​as a variable, and for the CMYK model there are 2 variables. After making a color card file, it is printed on the corresponding fabric for use. This method of coloring is simple and easy to use. Just compare the target color with the color card and select the same color. However, if this method is used, different fabrics may produce chromatic aberrations, so the color card fabric is the same as the target fabric. In addition, the three-dimensional stereoscopic subdivision of the color card will also affect the color effect. If the scale is too small, the number of color cards and the workload of the comparison will be greatly increased; if the scale is too large, the number of color cards will be controlled. Advantages: Easy to use, high color accuracy in the same fabric. Inadequate: different fabrics need to make different fabric color cards. Colorimetry This colorimetric method uses a spectrophotometer to perform color measurements on a target color patch, and transmits the measured results to a PC and prints out the colors. This method determines the color by the instrument, thus removing many artificial and environmental factors. When using this method, the sensitivity and accuracy of the colorimeter itself have a great influence on the measurement result; while the measurement result is inaccurate, it will directly affect the printing effect. On the other hand, consumables will also affect the accuracy of the colorimeter, because uneven surface of the fabric will produce different angles of diffuse reflection of light, thereby reducing the brightness and saturation of the measurement results, so that the printing color is darker than the original. The colorimetric method is suitable for use in highly saturated colors. It is not only easy to use but also very accurate. Introduce the type of over-cooled helium film for indoor and outdoor printing. The over-cooled enamel film can increase the picture quality, and protect the screen, which is resistant to scratch and water. However, photo images cannot be highly stain-resistant and resist UV-ray erosion. Ultraviolet light penetrates the cold laminating film to fade the picture, and for a long time, the cold laminating film is also brittle. Can be widely used in wedding dress, oil painting, calligraphy and painting, outdoor posters, advertisements, all kinds of pictures, documents, materials, and so on. Now available more than 20 models, various patterns, light / matte and laser series and other products. It can be used in larger advertising campaigns, construction and decoration renderings, and background decorations, etc. The use of cold laminating film covers better protection. Cold laminating film is made of transparent PVC by adhesive processing. According to the texture of the film surface, it can be divided into light film, matte film, frosted film, star phantom film, laser film and special texture protective film, which is widely used in advertising production. The film is a film, matte film, frosted film. The cold laminating film is covered with a hand or a cold laminating machine on the screen of the photo printing to prevent the screen (printed surface) from being scratched, contaminated, or wet, thereby protecting the screen. [Original content] For the normal printing, but the lack of strokes or colors, or high-resolution images under the blurring of this kind of minor blockage, generally using the printer's own nozzle cleaning program can be resolved, which is the staff often need to use the method And noteworthy aspects, that is, the lack of strokes or poor color, such as the discovery of a slight nozzle clogging, the cleaning process should be used as soon as the fading of the cleaning process is related to the strength, we know that the indoor photo ink production of pictures is the placement of households In places where there is no direct sunlight, only a few indoor lights are taken. In this case, if the dye has a light-fastness rating of 5 to 6, then it has an indoor storage time of two or three years (no visual seriousness). Fading) When the system is turned off, the system automatically resets the print head and printing paper after initialization. This will not only ensure the normal operation of the printer, reduce the failure rate and eliminate hidden troubles, extend the life of the printer, but also reduce the cost of printing supplies. Equipment maintenance costs greatly improve work efficiency. If the user forcibly removes the power plug from the printer when the printer is powered off, the print head cannot be reset, the top cover cannot be covered, the print head can be easily positioned and then the injector can be used to inject the cleaning fluid into the nozzle hole. If necessary, hard plastic can be used. The knife scrapes the residue from the orifice. Be careful not to contaminate the electrode during use. The problem of fading in photo printing - Shenzhen pictorial company photo The delicate picture, color saturation, gorgeous, over-excellent, is the advertiser's choice of print ads. Of course, the fading is related to the strength, we know that The photo produced by the photo ink is placed in a place with no sunlight in the room, and it only bears the illumination of some indoor lights. In this case, if the dye has a light-fastness rating of 5 to 6, the memory of the household is Put the time two or three years (no visual serious fading) here need the user's attention is that large-format color inkjet printer rack is large, light weight, there are rollers, very strong mobility, plug the power cord, be sure to put In areas that are not easily touched, avoid unintentionally dropping the power supply instead of a normal shutdown. 2. Provide a good environment for use Large-format color inkjet printer has a large number of tiny nozzles distributed on the print head. When facing such a large number of nozzles, it directly faces the printed paper when printing, and is exposed when it is not working. It is simple and good. Maintenance measures. Frequent ink filling or cleaning of the nozzle during the printing process, but the print effect is still poor or the print head nozzle is seriously blocked, the machine can not charge ink, or the printer refused to work this situation can only use manual cleaning method. Although the manual cleaning method is not complicated, but due to the need to disassemble the nozzle, especially in recent years with the price of domestic photo machine downscale, making the price of photo also fell, so more and more choose to print this type of print ads, in particular Some large shopping malls, supermarkets are the main consumer groups of photo ads, but the photo inks used in photo machines are water-based dye inks.
