Transparent Prints have color where should be transparent

[GayCarnes5341]

I am printing to an EPSON-2800 with Hiipoo sublimination ink.  I am using their ICC profile.  When I print a psd or a png file, it prints a light pink background where is should be transparent.  I never had this problem a few months agao.  But, it seems like the new Photoshop updates have changed something that I can't seem to cope with.  Please help!

I am using Photoshop 25.1 release, but this happened sometime before that.  I am printing to an Epson ET-2800 which contains sublimation ink.  I am using it to print to such items as coffee cups, tumblers, etc.  I need the print to be transparent; however, when I use a tumbler press to "bake" the logo or item on the cup, I get the pink hue background, and that will not do. I am attaching a photo I took of the print.  See attached  I am also attaching in .pdf format my settings in photoshop and print spec. I am using an .icc profile from hiipoo ink because that is the type of ink I am using.

I think I forwarded in the right area community.adobe.om, but no one has given me an answer.

I think it is important to know the RGB value of you "transparent" background. Is it a white background or a transparent layer? If it is transparent then I would suspect double profile printing. If the value of the "white" background is not 255,255,255 RGB values then there is the problem.

I have the exact same problem in this exact context

@PatChoq I suspect a colourmanagement issue, if you are printing from Photoshop are you using "Photoshop manages color" and selecting the correct ICC profile for your inkset and printer?

see also the reply from @Barry Rudick - the RGB values of the background should be 0.0.0 - if not you'll see a tint. 

I hope this helps
