Exclamation HELP - Problems with blk & wht photos - printing purplish

We are having issues printing black&white photos with our Kornit 932. The t-shirts (white t-shirts) always have either a green or purple hue. I'm wondering if it's a problem with the artwork that is being prepped or the management of the files afterwards in 'QuickP'.

Any tips would be much appreciated!

Thank you

Do you use QuickP Designer or any Photoshop action? If yes, use photoshop to see the ripped tif file. You can see the black area is composed by C:35, M:35, K:100 or something like these percentage.
Try to add more percentage in C and M channel, you will get more black image after print. If you don't add C and M, you will get a little blue or purple image on the print.
In my experience, if I want to print a black image, I will arise the C and M to 70% in pure black area.
If you want to get a better image, try to use photoshop to adjust the color channel. Don't trust QuickP Designer too much! A kornit engineer told me: "Photoshop can do anything!". QuickP Designer or Photoshop action is just a convenient tool, but not the perfect tool!

u r welcome. you still need use Designer to rip the file. and use photoshop to adjust the ripped tif file to get a better printing result.
in my experience, the red, gray, brown has the same problem. try to adjust the tif file then send it to print. the more you try, you will get more experience! wish you can get better print!

This problem is seem Gray balance on your file mis-matching with Kornit Printer.

Hi, Teera

What do you mean about gray balance? Can you describe it in detail?

Hi Earl

Now your problem is Grey Balance from CMY + K from color profile not balance mixed to Grey tone level.

hi, its also possible to print (with kornit and quick-p) with only black ink on white t-shirt,or only white ink on black t-shirt?
my t-shirt printer always adds all colors to my black and white pics(BW gradients mostly )..

i have one t-shirt from IF at home (look here: )

and the white area is pure white(without black or other ink), and blue is C/M i think.

i was thinking i will sent them *.PSD in BW mode next time, but how to make T-Shirt like IF above??

When you print, be sure to set your printer to "black ink only."
