Why Is My Dtg Magenta Ink Printing Blue

Written By Sunday, 3 July 2022 Add Comment Edit
  1. I have a Canon Pixma Pro 9000 printer, which until lately has given excellent service. Recently, however, reds are no longer coming out red. They are coming out brown, with a redish tint. All the other colors in the print are correct. I ran the head cleaning routine, but a clogged head is apparently not the problem. I calibrate my monitor, and I soft proof the image in Lightroom 5.7. I have tried printing from LR as well as letting the printer manage the colors. I tried converting the image to a 16 bit tiff with the Adobe RGB color space. But the results are all about the same, but the printer managed colors are slightly better, but nowhere near a bright red. I have a show coming up soon, so I need a solution fast - or I'll have to go outside for printing.
  2. There should be a utility to check the health of the print heads. You will get a grid of each color, C, M, Y and K, which should be continuous. If you have a partly clogged or defective head, you will usually get streaks. You know, of course, that the printer has no red ink. Red is produced by a combination of magenta and yellow. Heads do die, and can fail completely within two or three prints.
    There are printers with red, blue and green inks, in addition to the usual CMYK set. I don't thing the Pixma is among those hybrids, and I certainly wouldn't go looking for one.
    If you have a printer utility program to "calibrate" the printer-managed color, you might try that, and/or run a test print from that utility program. If a test print is okay, then you may have mixed or doubled print profiles in play. If Photoshop is directed to "manage the color" you need to make sure any built-in color control is disabled, and that you have a valid print profile available to Photoshop.
    You also get strange results if you "convert" an image to a print profile, then re-apply that profile when printing. Profiles and color spaces have the same structure, which can make things interesting if crossed.
  3. You know, of course, that the printer has no red ink.​

    This printer does have a red ink cartridge. It really helps to know about something before commenting. It's an eight color printer with CMYK, red, green, photo cyan and photo magenta.

    I'd look into software solutions, the Canon printer software is actually pretty good but you need to make sure you aren't running both its software and LR. When I was reviewing a similar Canon printer, there were problems if the Canon software was running and I printed through LR.
    Have you tried Canon support?

  4. Red ink? How nice! Then there should be a red pattern in a head check print, a normal precursor to cleaning, I should think.
    This question sat unanswered for nearly 12 hours. I try to help, and Jeff pounces on the messenger. Thanks.
  5. Download purge.zip at http://www.inksupply.com/purging.cfm There is a RED purge page in the file. You can scale it to full page if desired. Printing a single color patch that fills 1/3 to 1/2 a page shows the condition of the print head.
  6. Hi Edward-sorry about your experience; some people around here seem to act as if they have a chip on their shoulder (and they should know better). cb :)
  7. Thanks, everyone, for your response. I did run a head cleaning routine, and the red printed normally like the others - no streaks. I have not found a calibration routine, but will look again. I think something is wrong with the red tank itself, so I'm going to buy another red tank and see if that solves the problem.
