Hi-fi and inkjet printers

Although Roland's high fidelity inkjet printer is the only Pantone-licensed inkjet printer, there are many other brands of inkjet printers that also support hi-fi technology. The format varies, but most use more than four colors of ink. Some printers have original RIPs, and some require third-party RIPs. Wasatch is a manufacturer of RIP for large format printers. Although it does not have a Pantone license, it recently announced that it has been able to support "6+" color inkjet printer technology, including the Mimaki JV2, Roland Hi-Fi Jet and Epson 9000. The Mimaki JV2 is a 720 dpi six-color printer that can use a spot color in addition to six colors. The Epson Stylus Pro 9000 is a 1440*720 dpi large format six-color hi-fi printer. The performance of the Epson Stylus Color Pro 700 and 9000 is basically the same, but the format is smaller than the former and is 8.5 x 44 inches. ColorSpan also produces large format 4+ color printers. Among them, the DisplayMaker HiRes 8-color series uses C, M, Y, and K colors plus medium and medium M colors; there are two additional HiBrite Spot spot color inks (fluorescent inks can be used). The printer's basic resolution is 300 dpi and its maximum width is 72 inches. If we want to enjoy Hexachrome with only a small amount of investment, use a software that directly supports Hexachrome, or use HexVector to create a Hexachrome image. Then, enable the desktop printer's ICC Profile and print them out. This method can be used even for printers that use only four inks because the color gamut of such devices is usually 60% larger than the color gamut of CMYK. Using ICC Profile, we can also print scanned images in RGB mode with CMYK ink. The methods for simulating Hexachrome in the ICC workflow are: 1. An ICC profile with a scanner in an RGB scan image. 2. Use the CMM to convert the color data in the image to CIELBAB. 3. To emulate Hexachrome on a four-color device, the Hexachrome ICC-Profie should be used to convert the CIELAB values ​​of the RGB scan image to the percentage associated with the specific device. Subsequently, the device-related values ​​are returned to CIELAB. During the transition back to CIELAB, the image was mapped to the Hexachrome color space, but the L*a*b coordinates were still used. 4. Using the printer's ICC Profile, colors can be converted from the CIELAB color space to the printer's color gamut, so RGB images can be printed.
