Hi,

I am a new member here and new to sublimation printing. I am having problems with verticle lines during multi colour prints on white mugs, so I would be extremely grateful for any help and advice. I printed my first mug, it was just a 2 colour text and it came out perfect, however I then did a full multi coloured image (no text just a picture), and it produced verticle lines and some fading at the bottom near the corners of the print.

I checked my print setting and they were correct (mirror image, high quality, epson matte etc, correct colour codes), so I did another mug at 200 for 3minutes (as per a video suggestion on youtube) and I got the same effect only slightly worse.

My press will not go lower in temperature than 200 for whatever reason, so I am unsure if this could be a reason. I have watched a few videos about being 180 degrees for 180 seconds, but I am unable to get it down to that temperature. As its a generic make from china, I do not have a brand name to tell you unfortunately. It seems to be a standard heat press for mugs from what I have seen.

I have read threads on here with some very helpful suggestions for example, check the mugs as they may be not flush with the press and check them with each other, clean the print heads, quality of the paper, quality of the inks etc. I have tried this and I have got the same results.

I am using an epson ET -1810, with sub paper and inks from inkexpress and the press I have is a generic mug press only. I am not sure how to proceed with this.

Any advice or help would be greatly appreciated thank you so much in advance.

I'm new to sublimation myself, but as a general rule of thumb with print in general if you are getting very faint lines on the output then it would suggest an issue with print alignment or clogged print heads. I would suggest the first port of call is you need to check alignment on the print and also run a print head clean, maybe even an in-depth clean through the printer system. Even if you have done this in recent weeks might be worth revisiting it.

Is the press set to *F instead of *C

Lines on the print could be a few different issues but mainly nozzle clogging or paper.
Post some images of the issue that always helps.
