What is the experience in setting up the color management system of Micolorprint printers?

Table Of Contents

In recent years, the sales of flatbed printers have been the champion of the printer market, and even the laser printers with the highest speed and text printing quality cannot compete with them. This is of course due to the fact that inkjet printers can provide high-quality color printing at lower prices.

If users want to get as close to the photo-level and “authentic” printing effect as possible, in addition to purchasing higher-grade inkjet printers and related accessories such as ink cartridges and paper, they must also pay attention to printers, monitors, scanners, and Application software’s color management system settings. To this end, we might as well listen to the views of major inkjet printer manufacturers.

HP: The best choice is sRGB

sRGB is a color management system developed by Microsoft and HP (Hewlett-Packard) for two years. It was launched at the same time as the PhotoREt II technology of HP inkjet printers. And ICM (Image Color Management) 1.0 and 2.0 are the built-in color management systems of Windows 95 and 98 respectively.

According to HP, the effect of ICM is not as obvious as that of sRGB. After using sRGB, the color of the monitor and the color inkjet printer is relatively consistent. And HP’s new printers and scanners have already made sRGB settings after installing the drivers, and users do not need to adjust them by themselves.

However, sRGB needs the cooperation and support of hardware, operating system, and application software to be effective. Therefore, it is not enough to have a color inkjet printer that supports sRGB. If it is used with Windows 95, it still cannot achieve the effect of sRGB (because Windows 95 does not support sRGB). This also happens to application software.

Therefore, HP recommends that in order to achieve a more consistent color effect for color printers, scanners, and monitors, in addition to the hardware itself supporting sRGB, it should also cooperate with Windows 98 and newer application software, such as Adobe Photoshop 5.0 or above, CorelDraw 8.0 or above, Microsoft Picture It 99 or above, etc.

As for users of HP inkjet printers, if you use monitors of individual brands such as Sony, NEC, and Hitachi, you should select Trinitron Compatible 9300K G2.2.icm, NEC Compatible 9300K G2.2.icm when setting in Windows 98 , Hitachi Compatible 9300K G2.2.icm, or sRGB Color Space Profile.icm? HP said that from their standpoint, users would be advised to choose sRGB Color Space Profile.icm.

Epson: Choose as needed

For Epson, the color inkjet printers launched in the past two years already support the ICM color management system. The latest Stylus Photo 870 supports both ICM and sRGB, as well as Epson’s own color management technology – PhotoEnhance4.

PhotoEnhance4 is mainly designed to allow users to easily create special image effects, including effects such as nostalgia, oil painting, parchment, and soft focus. Users can use it with just one click. In addition, it has a “magic trimming function” designed to improve the quality of low-resolution pictures – Digital Camera Correction (Digital Camera Correction), which can slightly enlarge the small low-resolution pictures on the Internet before printing. Of course, if the resolution of the photo is high enough, the contrast, tone, and brightness are ideal, and the user does not need any special effects, then there is no need to use the PhotoEnhance4 function.

Taking the same print sample as an example, the images printed by Epson’s own color management technology, or ICM, sRGB, etc., sometimes have slight differences. So how should users choose? Epson said it is difficult to generalize which color management technology is best and should be based on user requirements. Because the print closest to the display is not necessarily the best, and vice versa, it is not necessarily possible to have both at the same time. The reality may be that one color management technology provides a print that is closer to the display, while another color management technology provides a better print (such as higher contrast, etc.). Users can choose according to their own requirements.

As for Epson’s scanners, Epson’s own color management technology is used. When setting in Windows 98, users of Sony, NEC, and Hitachi should select the ICM files of Trinitron, NEC, and Hitachi respectively. Users of other brands can choose sRGB Color Space Profile.icm.

How to set up a color management system´╝č

Based on the opinions of the above parties, computer users should pay attention to the following points:

1. Select hardware that supports ICM (preferably ICM 2.0) or sRGB, including printers, monitors, scanners, etc.

2. Use Windows 98 and newer application software to support ICM or sRGB as much as possible.

3. In Windows 98, when setting the color management settings associated file of the monitor, Sony and Mitsubishi users should choose “Trinitron Compatible 9300K G2.2.icm”; while NEC should choose “NEC Compatible 9300K G2.2.icm”; Hitachi chooses “Hitachi Compatible 9300K G2.2.icm”; users of other brands should choose “sRGB Color Space Profile.icm”.

4. Users of Sony and Mitsubishi monitors should adjust the Color Temperature to 9300K.

Other considerations

1. If the print head is on the ink tank, a test page should be printed (selected in the driver) after each replacement of the ink tank, and the number should be entered in the driver for correction. Otherwise, the printed lines may not be straight.

2. Some inkjet printers such as HP DeskJet 970Cxi have the function of Automatic Cartridge Alignment after replacing the ink tank, which can automatically print a test page for calibration without inputting any numbers. Because this type of printer shoots some light onto the paper and bounces the light back, it corrects itself automatically. Therefore, be sure to use brand new white paper to print the test page.

3. Epson’s color inkjet printers use permanent print heads, which do not need to be calibrated after replacing the ink tank. But in terms of maintenance, you should be more careful, and you should perform “Nozzle Check” (selected in the driver) every two to four weeks to see if the printed test page is “broken”. If so, the print head should be cleaned (selected in the driver). If the printing effect is still unsatisfactory after cleaning once, you can repeat the above steps.

4. The print heads of other brands of color inkjet printers are mostly on the ink cartridges. If you feel that the printing effect is unacceptable, you can replace it with a new one.

5. When the printer is not in use, the paper should not be exposed for a long time. Otherwise, the print head will collect dust as it passes over the paper, blocking it. This particularly affects Epson’s color inkjet printers, which use permanent printheads.

6. It is best to use the original ink, because the alternative inks introduced by other manufacturers are more likely to cause the print head to block, which has the greatest impact on Epson color inkjet printers that use permanent print heads? No

7. If you don’t mind the price, it is best to use the original special printing paper. Because the special paper developed by some manufacturers is not suitable for all brands of color inkjet printers.

8. Do not take out the ink tank casually. If it is really necessary, it should also be stored in the plastic box to prevent the ink from being air-dried.

9. Avoid crumpled paper as it is easier to jam. If you do encounter it, you should turn off the printer first and then try to remove the paper, so as not to damage the motor that feeds the paper.

10. Since the inkjet printer is a line printer, the data transmission speed is not as high as that of the laser printer.

Therefore, many users think that the USB interface only affects the startup time of the inkjet printer, and once the printing starts, the USB does not help to improve the printing speed. Actually, this is not necessarily the case. Taking HP DeskJet 970Cxi as an example, if you print a large file, the speed is obviously faster and smoother when using the USB interface; while when using the parallel interface, the ink cartridge will “stay” at one end after completing a round-trip printing. . Therefore, if the printer has a USB interface, it is, of course, better to use a USB connection than a parallel port.
