Color test for the Epson printer. How to test the quality of inkjet ink at home

Focus on the non-calibrated monitor is difficult, as the similarity of the prints with the monitor screen will be partial.

For check color profile There are three options. The first way to print black and white photos - they should be black and white, without color impurities. You need to look after complete stabilization of ink and at the source, which is ordered by the color profile. The second way is to print photos and comparing them with a calibrated monitor. It is possible that we will have to compare in paper imitation mode. This can do photoshop, illustrator, indison, coreldraw. The third way is to print our test images and visual analysis of their quality. The fact is that sometimes the printed image in itself has a color shift, especially when shooting indoors. We tried to collect images without explicit color deviations.

Presented two blocks of images:

  • Check RGB drivers. Printing from Windows native printer drivers. RGB Color Profile.
  • Check photo laboratories (wet printing). RGB pictures.

Color-rich test images for checking a photo laboratory (wet printing).

Each user after purchase new techniqueShe strives to try it as soon as possible in the case. Of course, it concerns printers. The only correct way to check the printing device is a stamp of a solid page. This procedure will make sure that all the basic settings of the device were set correctly, you can additionally make sure that the color is transmitted in full compliance with the desired result.

In addition to the information listed, printing the trial page on the HP printer will learn the exact version of the drivers and the model itself. All information presented may well come in handy in case any problems or additional questions arise.

Trial Printer on HP Printer

Press the left key of the button "Start in the taskbar and from the Services list to select" Control Panel.

Mouse over your selected printer and press the right key. The printer context menu appears. From the context menu, select the "Properties command and click on it left key.

In the "Properties of the Open tab of the General tab and press the left mouse button on the TRACK printing command. If the printer launches for the first time or they did not use for a long time, it will be necessary to wait a few seconds (from 15 to 30) before printing starts. Just the printer driver is needed to collect all information about the system. In the future, printing speed will be higher. The parameters of the test page of any printer are default and printable all printer parameters are tested when printing. The test page on different models may differ.

When the seal is over, rate the test page. It must contain graphics, text, samples of absolutely all colors. There should be no distortion and irregularities. If the seal has been made using an inkjet printer, there must be no paint drums.

When the printer completes the print page, the proposal will follow the Save Print Parameters. If all the parameters of the test page are satisfied with you, you can simply click on the "Save Print Parameters by default.

How to print a HP test page without a computer?

To start, download the usual white sheets of paper of the appropriate format in the input tray.

Print Test Page for inkjet printers It is printed as follows: Turn off the device with a button, click the "Sheet, without relearing it, click the" ON, release it, continue to hold "a sheet of about 10 seconds.

What problems can I arise?

But sometimes the next problem occurs: the test page is printed incorrectly. In this regard, the question arises about what to do in this case and how to print this page? So, if the test print page is not correctly printed, then one of possible problems lies in old or "broken drivers.

To solve it, you need to download and install their updated version. But what if this action did not help and the problem associated with the fact that the printer does not print before the printer remains relevant? In this case, give complete "Everyone for" C: \\ Windows \\ System32 \\ Spool \\ Printers, after which you remove the desired printing device on the HKEY_USERS \\ .Default \\ Printers registry branch.

In addition, give the usual user to the right that admin possesses and install a new driver under his name. After that, it is possible to re-remove the rights previously provided. You should also disable UAC. If the actions taken will not help, then the Process Explorer utility should be launched and during printing to pay attention to what rights is missing.

To assess the quality of inkjet ink used three types test pages : TF1, TF2 and TF3.

Test page TF1 Used to test the quality of color ink. It allows you to analyze the ability of ink to produce accurate color reproduction of shades and halftone.

Test File Test Samples

The TF1 test page is printed on standard A4 paper. It represents a combination of monochrome and color images, multi-colored square "dies" and sections with a gradient fill from zero to one hundred percent.

With the help of the TF1 test page, it is possible to objectively evaluate both the color reproduction of any one inkjet ink, and organize comparative testing of several types of ink.

To determine the quality of the color reproduction of inkjet ink, the obtained TF1 test pages are digitized with a color scanner. The resulting files are used to determine the RGB components in certain areas of the page. To do this with a graphic editor Adobe Photoshop. The result of the transfer of primary ink colors is recorded, and the data obtained are recorded in the colors table. The resulting table allows you to determine the correction factor in ink in different colors and shades. This coefficient is calculated by the formula:

Formula definition of the correctness coefficient

The lower the ratio of the correctness of the playback of colors and shades, the more accurate color reproduction will provide ink ink for the printer.

The data obtained when checking the quality of the inkjet ink color renditions allow you to construct a graph in which we lay the distance on the axis x, the pixel values \u200b\u200bon the axis. We connect the dots and get a single line, failures and peaks on which indicate an unbalanced color transmission. If there are no dips and peaks, the color rendition is balanced. The recommended range of RGB values \u200b\u200bshould not exceed 255.

The next test page, which is used to assess the quality of inkjet ink, is the TF2 page.

Test page TF2.

Test page TF2. - This is a PDF file consisting of several groups of elements, which, in turn, include six parts independent of each other located vertically and horizontally. Groups of elements of the TF2 test page are numbered, with each previous element a little more than the subsequent. Quality Printing of the smallest elements of the test page determines the resolution of inkjet ink.

Test Pages TF2 are used to test monochrome and color inks for inkjet print. For printing TF2 pages, A4 paper is used. At the same time, when testing monochrome ink, standard office paper is used, and when testing the colored ink - photo paper.

The third type of test pages is the TF3 files used to determine the quality of monochrome black ink.

    Perfect test list. This example shows how impeccable printing should look like.

    Repeatable black dots located vertically on a white test sheet. This test list characterizes the most common type of marriage - the point breakdown of the photottery of the photobaban. The tributes are of different diameters: from barely distinguishable points to oily spots. In this case, there is a need for a complete replacement of the phototraban, since there is no technology to restore it. This solution It is accepted depending on the client's requirements for print quality, since small point triggers when printing only texts are practically indistinguishable and there is no need to replace the photobaban. But over time, points are increasing in size. Then you can think about replacing such an important component.

    Marriage of the magnetic shaft. The vertical strip on the black test list indicates the presence of scratches on a magnetic shaft, which is marriage. In this case, the magnetic shaft is subject to a mandatory replacement, since the light strip significantly worsens the print quality of the text and pictures.

    Solid vertical black stripe on a white test sheet. The appearance of a solid or intermittent vertical one black or several bands along the edges of the white test sheet speaks of serious damage to the photo film on the drum. Otherwise, such drums are called "burners". These defects are well different from the naked eye. Photoslah in the place of damage has a characteristic brown color or in the absence of the following layers. Photorabank is subject to mandatory replacement. On the black test sheet, with such defects, an intermittent strip can be seen on the edge.

    An example of marriage cartridges Samsung and Xerox. They differ from defects on HP and Canon cartridges due to the difference in the technological device. Stains on both test sheets, vertical stripes on a black test sheet and repetitive horizontal points on white talk about the need to replace a large rubber shaft, photobraba.

    Toner ends. The photo shows how the test list looks like when the toner cartridge ends. This is especially well noticeable on a black test list. This example is not a defect. Just it is time to fix the cartridge.

    Divorces and waves on light dough. The occurrence of divorces and waves on the light dough speaks of incorrect storage of the cartridge, as a result of which he has dumped. In this case, the consumility must be cleaned from the old toner and to fix in a new one.

    Vertical strip, pallor print.The pallor of printing, a well-distinguisable vertical strip on a black dough occurs with scratches on a magnetic shaft, as well as its strong wear. The same signs appear during the burnt photographers. To improve print quality, it is advisable to replace worn and damaged components.

    Toner Nalip on Raquel. Sometimes the toner can pour on various parts of the cartridge under the influence of temperature increase in the printer during operation, significantly worsening the print quality. It is necessary to clean the rhael, remove the excess toner with parts.

    We talked about the main defects of cartridges and their impact on print quality.

From the printer in domestic use, if, of course, it does not apply to play photos, rarely when something except the clarity of the letters and duration of life is required. But if the machine is used to print non-ferrous products, the requirements for it immediately increase. And here it becomes important not only the number of points per inch or clarity of the image, but also chroma.

Checking the printer printing is carried out using special test pages.

When checking is conducted

The quality of printout is important for any document - and monochrome, and color. Accordingly, the test procedure is carried out in several cases.

  • When buying a new device, it is often not possible to check the operation of the device in the store. However, at home, nothing prevents the user to download the corresponding tests and find out how much the playback is true.
  • Cartridges over time are exhausted and required or charge the device by purchasing the appropriate set, or buy a new cartridge. However, not all ink are compatible and sometimes for HP apparatus have long to look for special. However, it is not only in the mismatch of the characteristics of the fluid for different printing devices - the case is also in different colors.

When buying a cartridge or filling in a licensed store, the likelihood that the ink shade will be exactly the coincidence with the apparatus, much higher. However, not all users have physical or financial opportunity Purchase special inks. Accordingly, the user has to select all compatible options.

Of course, after installing a new cartridge, you need to spend a test to understand how the shades coincide with the previous ones.

  • Also check the color printer with the planned translation of the device to other inks - with pigment to water, for example. In this case, make sure that the device's adequate operation.

Test pictures will be required to determine the status of the printhead. Over time, it is contaminated and the printing of the corresponding image allows you to determine the level of pollution and exercise the extension. Such a procedure is standard and enters software printer.

Analysis of the work of the device

To find out how high-quality ink is purchased, the bought printer of the Epson line is carried out tests. It will take high-quality paper - white matte, since any shade of the leaf will spoil the test, the actual printing device and the cartridge with new ink.

The test protrude colorful pictures with certain specified parameters, which allow you to evaluate gradient, compliance with the shade, playback capabilities and other print parameters. Ourselves test tasks It is easy to find on the Internet and upload to the HP device.

Pictures for checking the printer should include:

  • gradient transition from black to white, with the inclusion of a given number of shades of gray;
  • portrait, and, more precisely, photography, with natural skin color and unfastened pores;
  • an image of bright details on a dark background, as well as dark elements on light;
  • test strips with different colors.

In addition, for cleaning nozzle or analyzing the status of printheads use a test black page. If the shade is not saturated and uniformly, it is necessary to carry out the cleaning procedure. In the same Epson, for this, the "Test Check" is chosen in the window and the test result assigns cleaning.

Each such an element serves to check one of the playback parameters. If the device is used only for home printing, you can limit the two first parameters.

But if you assume to print photos for commercial use, you should pay attention to all factors. At the same time, analyzing the resulting image, you should pay attention not to the exact reproduction of the color compared to the original, but on the balance of the selected ink set.

The color picture for checking the printer is analyzed as follows:

  • first of all, they estimate the fill with gray. If all of its shades exactly coincide with the reference image, the ink can be used. If the color is distorted at least in one position, alas, the cartridge is far from the ideal. It is the very presence of an extraneous shade that allows you to determine ink ink. This is relevant for analyzing the work of any HP devices - Epson, Canon;
  • drawing the smallest details of both bright and darkness also indicates the quality of ink. With high-quality materials, the drawing will be the most detailed as possible;
  • color reproduction distortion is best determined by the human portrait or image of living objects. Color range of non-living items - still life is not so informative, while determine the realism of the shade of human skin is much easier.

You can adjust the color to some extent using the settings of the device itself. If the Epson printer check led to unsatisfactory results, you can try to use software settings. To do this, in the corresponding tab, "Printer Setup" and adjust the semitone curve.
