Mutoh 1641sr printing cyan blue halo in place of white (white being turned blue)

[JessiTheBestiArt]

I've got an interesting problem that started happening recently. If I put something into flexi and send to vertelith with a white outline, it will print every are that is supposed to be white, a light blue. Letters, eyeballs... Everything is being printed this blue color. I did a nozzle check, they're fine. Printed the 100% CMYK boxes.. yellow looks a little off but everything seems fine. I changed from absolute colormetric to perceptual. Everything is set to the srgb 2.1 icc profile..

I had to turn cyan all the way to 0% to get rid of the blue halo.. and this isn't a permanent fix because most of my art has white or purple/blue

If I had to guess...
There's clearly a problem with vertelith overcompensating for something...
I used the 900x1200 matte heat transfer vinyl profile in vertelith.

Any suggestions?

Try making anything that's white, clear/cut out instead. Each material has a different white point. It sounds counter intuitive but, a lot of the time, the RIP will add a little cyan to white areas to make it look more white because the white of the material isn't quite white and it tries to compensate. If you tell that white area to just print nothing instead, it will only show the white of the vinyl without printing anything extra.

The fact that this just happened out of the blue though could mean something else changed. Maybe you changed profiles?

I did try that, but when I throw it in flexi it adds cut paths to everything - like all around the letters and the eyeballs.. so then I have to manually remove all those little cut paths which takes time.

Ideally, you would make your own color profile and linearize the head output so that white prints white every time but that costs some dough. If the cutout solution works and the only thing holding you back from using it is the contour problem in Flexi, there should be a little check box in the Flexi contour cut window that is labeled something like "With Holes" or "Without Holes". Try turning that on and off and it should give you the option to only do the contour around the whole image and not cut out anything inside it.

Interesting, how the hell would I go about making my own color profile? Are there not some good icc profiles that don't rend towards cyan? I will try that! The holes thing, thank you!

It requires equipment and software or you can hire someone to do it. You can try a bunch of other profiles and see if it helps. At the end of the day, profiles are supposed to calibrate everything based on your printer, media, and environment so using profiles made on another machine, in a different environment will give different results. It's usually good enough for most people but then you run into issues like this and it becomes a problem.

It could still be something else but that's what I'm leaning towards. The nozzle check looks solid and it's not over spraying or anything.

Do you sell icc profiles by chance? Also here is a side by side comparison from my canon pro and my mutoh. Contacted sign warehouse and they say it's because the file is low quality... The file is 75mb, I don't see how that's low quality but okay. Thanks for your help!
